On t h e d a t e o f t h e a c c i d e n t , B a r t e l was 2 4 y e a r s o l d , weighed 318 p o u n d s , was 6 f e e t , 4 i n c h e s t a l l and was n o t p h y s i c a l l y o r mentally impaired. Rartel was a truck driver living in Ronan, Montana, a p p r o x i m a t e l y 14 m i l e s n o r t h o f S t . I g n a t i u s . On t h e d a t e o f t h e a c c i d e n t , B a r t e l had l i v e d i n Ronan f o r a b o u t 6 y e a r s and had done at least a normal amount of occupational and recreational traveling i n t h e Ronan a r e a b y m o t o r c y c l e and four-wheel drive vehicle. Beginning in July 1979 and c o n t i n u i n g t o t h e d a t e o f t h e a c c i d e n t , B a r t e l had d r i v e n by St. I g n a t i u s about once a day w h i l e d r i v i n g a logging t r u c k between Ronan and Thompson F a l l s .

Around 9:00 p.m., Bartel met two other friends, George I Mitchell and Gerald Cooper, at another Ronan bar, where B a r t e l d r a n k a t l e a s t two d r i n k s c o n s i s t i n g o f s c o t c h whiskey and w a t e r . Shortly a f t e r this meeting, Bartel traded his pickup truck for Mitchell's motorcycle.

After this meeting and exchange of vehicles and t h r o u g h o u t t h e rest o f t h e e v e n i n g u n t i l 1:00 a.m., the t r i o visited various bars between Ronan and St. Ignatius. Numerous witnesses testified at trial regarding how many d r i n k s B a r t e l had a t e a c h b a r and w h e t h e r and t o what d e g r e e he became intoxicated. Bartel argues that the testimony e s t a b l i s h e s h e had no more t h a n 9 d r i n k s o f s c o t c h and w a t e r between 9:00 p.m. and 1:00 a.m. The State contends the e v i d e n c e e s t a b l i s h e s t h a t B a r t e l had a b o u t 15 d r i n k s between 9:00 p.m. and 1:00 a.m. and 18 d r i n k s t o t a l f o r t h e day.

As Bartel drove through t h e i n t e r s e c t i o n , he s t r u c k t h e n o r t h e r n t i p o f t h e t r a f f i c i s l a n d w i t h t h e m o t o r c y c l e , l o s t c o n t r o l and came t o r e s t a b o u t 50 t o 60 f e e t n o r t h i n t h e b a r r o w p i t on t h e r i g h t s i d e o f t h e highway. Bartel was taken immediately to the St. Ignatius hospital, where personnel quickly determined that the s e r i o u s n e s s of h i s i n j u r i e s r e q u i r e d t r e a t m e n t i n M i s s o u l a .

The treating neurologist examined Bartel and concluded, among other things, that Bartel was in a state of "alcoholic intoxication." A blood-alcohol t e s t , p e r f o r m e d on B a r t e l s o l e l y f o r medical purposes, i n d i c a t e d a blood-alcohol l e v e l of .I71 percent. Rased upon the .I71 percent test result, expert witnesses testified at trial that Bartel's blood-alcohol level was between . l o 3 and .213 p e r c e n t a t t h e t i m e o f t h e a c c i d e n t . The complaint sought damages for personal injuries resulting from t h e m o t o r c y c l e a c c i d e n t a l l e g e d l y c a u s e d by the State's negligence in design and maintenance of the intersection and surrounding area. After extensive discovery, the c a s e was tried before the Lewis and C l a r k County D i s t r i c t C o u r t , s i t t i n g w i t h o u t a j u r y .

" Bartel challenges these three findings of fact. In addition, t h e d i s t r i c t c o u r t found t h a t t h e n i g h t o f the a c c i d e n t was dark b u t clear, the roadway was dry and clear, and no o t h e r t r a f f i c was involved i n t h e accident. The court found that the headlight on t h e motorcycle was functioning normally and that all traffic signs could be discerned clearly with t h e headlight. The c o u r t found t h a t B a r t e l , a t a s p e e d o f 25 t o 30 m.p.h. and w i t h o u t b r a k i n g o r decelerating, passed a c r o s s t h e r o a d ' s yellow d i v i d i n g l i n e and the left lane, collided with the traffic separation i s l a n d toward i t s n o r t h e n d , l o s t c o n t r o l of h i s motorcycle and l a n d e d w i t h it i n a d i t c h on t h e r i g h t s i d e o f t h e r o a d . The c o u r t found t h a t u n d e r t h e l i g h t and w e a t h e r c o n d i t i o n s e x i s t i n g a t t h e t i m e o f t h e a c c i d e n t , an o r d i n a r i l y o b s e r v a n t motor v e h i c l e o p e r a t o r t r a v e l i n g i n B a r t e l ' s d i r e c t i o n c o u l d have s e e n from a d i s t a n c e o f n o t less t h a n 350 f e e t t h e end o f t h e t r a f f i c i s l a n d which B a r t e l h i t and c o u l d h a v e s e e n other indications of the proper route through the intersection. The court found that if Bartel had been d r i v i n g i n a r e a s o n a b l y c a r e f u l and p r u d e n t manner and n o t u n d e r t h e i n f l u e n c e o f a l c o h o l , h e c o u l d have e a s i l y a v o i d e d t h e c o l l i s i o n w i t h t h e t r a f f i c i s l a n d and t h a t B a r t e l was n o t in any way "trapped" by highway design, signing or maintenance. Although t h e c o u r t found t h a t t h e d e s i g n , c o n s t r u c t i o n , s i g n i n g and m a i n t e n a n c e o f t h e i n t e r s e c t i o n was " d e m o n s t r a b l y deficient in numerous respects and did not comport with n a t i o n a l s t a n d a r d s o r even t h e S t a t e ' s own s t a n d a r d s , " t h e s e d e f i c i e n c i e s were n o t found t o b e a c a u s e o f t h e a c c i d e n t . The c o u r t n o t e d t h a t no o t h e r a c c i d e n t s a t t h i s i n t e r s e c t i o n had been reported since 1969, when the traffic i s l a n d was installed. The court concluded that Bartel was negligent in violating several t r a f f i c safety s t a t u t e s , including driving while under the influence of alcohol. The court also concluded that Bartel was negligent in failing to see a h a z a r d which a r e a s o n a b l y p r u d e n t p e r s o n would see u n d e r t h e circumstances o r , h a v i n g s e e n i t , i g n o r i n g it o r f a i l i n g t o r e a c t t o it i n a r e a s o n a b l e and p r u d e n t manner. The c o u r t concluded that Bartel's negligence was the s o l e proximate cause of the accident. The c o u r t a l s o c o n c l u d e d t h a t any negligence of the S t a t e was n o t i n any degree a proximate cause of t h e accident. Bartel appeals. I Did t h e d i s t r i c t c o u r t err i n a d m i t t i n g i n t o e v i d e n c e without adequate foundation t h e r e s u l t s of a blood-alcohol test? Bartel contends that evidence of blood-alcohol test results was inadmissible because the State failed to establish the required foundation for i t s admission, as required by McAlpine v. Midland Electric Company (Mont. 1 9 8 1 ) , 634 P.2d 1166, 38 St.Rep. 1577. Bartel argues t h a t a l t h o u g h less s t r i n g e n t f o u n d a t i o n a l s a f e g u a r d s a r e r e q u i r e d f o r admissibi-lity o f blood test r e s u l t s i n c i v i l c a s e s than in criminal cases, McAlpine n o n e t h e l e s s requires that test p r o c e d u r e s a c c o r d w i t h "good p r a c t i c e i n t h e f i e l d " t o a s s u r e reliable results. Bartel a l l e g e s numerous i n a d e q u a c i e s i n the blood test procedure which h e contends a r e deviations from good medical practice. He alleges these deviations render the test results in this case unreliable. Bartel contends there is no evidence other than the blood test r e s u l t s t h a t h e was i n t o x i c a t e d o r i m p a i r e d i n h i s a b i l i t y t o drive. Because the State's defense depended upon showing t h a t B a r t e l was i n t o x i c a t e d , B a r t e l a r g u e s t h a t t h e e r r o n e o u s admission of Exhibit X I t h e l a b r e p o r t containing t h e blood test results, was extremely prejudicial and constitutes reversible error. A review of the detailed foundation testimony is appropriate here. Three h o s p i t a l employees testified at trial regarding Bartel1s blood test and routine blood test procedure. B a r b a r a Westphal-Marcus, a n R.N. who p a r t i c i p a t e d i n B a r t e l ' s emergency room treatment, charted the treatment Bartel received. The c h a r t showed t h a t a n I V was s t a r t e d a t 3:30 a.m. and that the drug mannitol was administered at 3:35 a.m., a l t h o u g h t h e c h a r t d i d n o t show s p e c i f i c a l l y when b l o o d was drawn. However, Westphal-Marcus testified that as a m a t t e r o f r o u t i n e p r a c t i c e , b l o o d i s drawn f o r t e s t i n g when an IV is started. She described routine procedure for s t a r t i n g a n I V and d r a w i n g b l o o d f o r alcohol testing: the patient 's arm is prepped with betadine, a non-a l c o h o l i c s o l u t i o n ; t h e n e e d l e and c a t h e t e r a r e i n s e r t e d ; t h e n e e d l e i s then removed from the catheter; before the blood-drawing s y r i n g e i s i n s e r t e d i n t o t h e c a t h e t e r , b l o o d i s s p i l l e d from the catheter; t h e s y r i n g e i s i n s e r t e d a n d 10 c c ' s o f b l o o d are drawn; the blood is put immediately into two tubes, marked with the patient's name and ER chart number, and handed t o t h e l a b t e c h n i c i a n . Westphal-Marcus t e s t i f i e d s h e was p r e s e n t when B a r t e l ' s b l o o d was drawn. She s t a t e d t h a t b a s e d on r o u t i n e p r a c t i c e , Bartel's blood was drawn at 3:30 a.m. when the IV was started. Responding to questions from the court, she indicated that nothing unusual had been done in Bartel's case. While betadine is usually used f o r p r e p p i n g where alcohol testing is anticipated, Westphal-Marcus could not s t a t e w i t h c e r t a i n t y t h a t i s o p r o p y l a l c o h o l was n o t u s e d on this occasion. However, she stated that t h e blood spill which occurs before the syringe is inserted and b l o o d is drawn would remove any t a i n t c a u s e d by u s e o f a n i s o p r o p y l alcohol prepping solution. She n o t e d t h a t i n B a r t e l ' s c a s e a l a r g e c a t h e t e r was used and a l o t o f b l o o d was s p i l l e d . She concluded that good medical practice was used in drawing B a r t e l ' s b l o o d and t h a t t h e t e s t r e s u l t s w e r e r e l i a b l e . L e i l a n i Heuer i s t h e l a b t e c h n i c i a n who t e s t e d B a r t e l ' s blood. She recognized and identified Exhibit X as an a c c u r a t e copy o f the l a b r e p o r t s h e had p r e p a r e d from t h e original test printout and signed the night of Bartel's accident.

I n McAlpine v. Midland E l e c t r i c Company (Mont. 1981), 6 3 4 P.2d 1166, 38 St.Rep. 1577, t h e a p p e l l a n t r a i s e d s e v e r a l arguments r e g a r d i n g foundation f o r admission of blood-alcohol test r e s u l t s which are similar t o those raised by B a r t e l . There, appellant argued t h a t t h e proponent o f t h e evidence had f a i l e d t o show t h a t post-mortem blood clotting did not r e s u l t i n a h i g h e r b l o o d - a l c o h o l r e a d i n g ; f a i l e d t o show t h a t the procuring and testing of the samples followed the procedures s e t o u t i n t h e A d m i n i s t r a t i v e R u l e s o f Montana; failed to show the blood tested came from the victimsf bodies; and failed to produce the gas chromatograph records which recorded the test results. 634 P.2d at 1170, 38 St.Rep. at 1582. In McAlpine, this Court held that procedures required by administrative rule where results are to be used in a criminal prosecution are not required for admissibility of test results in a civil trial. In so holding, we quoted from Bach v. Penn Central Transportation Company (6th Cir. 1974) , 502 F.2d 1117, which stated that while test procedures for civil trial use need not comply with criminal case statutory procedures, l1 'they must accord with good practice in the field to assure reliable results.11' McAlpine, 634 P.2d at 1171, 38 St.Rep. at 1583, quoting Bach, 502 F.2d at 1121. We concluded that testimony in that case "established that the procedures employed followed good practice in the field. " 634 P.2d at 1171, 38 St.Rep. at 1583-84. We adhere to that test today. Rule 406(b), M.R.Evid. provides that "[elvidence of habit or of routine practice, whether corroborated or not, and regardless of the presence of eyewitnesses, is relevant to prove that conduct on a particular occasion was in conformity with the habit or routine practice." l1 Routine practice" is defined as "a regular course of conduct of a group of persons or an organization." Rule 406 (a), M.R.Evid. Hospital personnel and medical experts testified at length of the routine medical practices employed at the hospital in drawing and testing blood for alcohol content. These witnesses also testified at length as to whether those practices accord with good medical practice. With the single exception of Bartel1s expert witness, all witnesses testifying on this point agreed that the procedures employed were in accordance with good practice and yielded reliable and accurate results. During the extensive foundation testimony heard prior to admission of Exhibit I, the experienced trial judge questioned the witnesses in detail on various points. In response to a question from the court, Westphal-Marcus indicated she believed that the blood drawing procedure used in Bartel's case did not deviate from routine hospital procedure. Further, Heuer stated that she performed the Bartel blood test using good, reliable procedures. The above testimony, together with testimony specifically relating to Bartel's blood test, was relevant and provided adequate foundation to support admission of Exhibit X. We hold that the record contains substantial credible evidence to show that the test procedure employed in this case accorded with good medical practice to assure reliable results. Bartel vigorously emphasizes those portions of the testimony which he argues support his contention that the blood test results were inadmissible. He argues the necessary foundation was not established because the State failed to establish certain facts which he argues are essential to admissibility of the results. We will discuss each of these contentions in light of the record. 1. Bartel argues that the State's failure to identify positively the person who drew Bartel's blood precludes admissibility of the test results. The testimony of R.N. Westfall-Marcus established that she was present for the drawing of the blood specimens from Bruce Bartel as was Bill Kirk, R.N., Jackie Clausen, Night Supervisor, and the medical doctor. While she was present at the time of the blood drawing, she could not recall whether she or Nurse Kirk had drawn the blood sample. She did testify at length regarding the procedure customarily followed in the drawing of blood. Her testimony and that of other witnesses established that the two registered nurses were both qualified to draw blood and were both familiar with routine hospital practices. Nurse west fall-Marcus completed a portion of the emergency room records with regard to the treatment of Mr. Bartel, particularly the cross-matching of blood and the ordering of the blood test. The routine procedure used by Nurse Westfall-Marcus and other nurses in the hospital was established without contradiction. There is nothing in the written records to indicate any deviation from these proce- dures. Nurse Westfall-Marcus testified there was no deviation from routine procedures. Mere inability to recall which of two registered nurses completed this particular blood test after a lapse of two years is not a sufficient basis to challenge the admissibility of the blood test itself. While it would have been preferable that the name of the nurse withdrawing the blood be shown on the emergency room records, Nurse Westfall-Marcus indicated they were so busy taking care of the severely-injured patient, Bartel, that this had not been placed on the records. The testimony established the very large number of blood tests conducted by hospital personnel and by Nurse Westfall-Marcus in the course of emergency room operation. Under the circumstances of this case, the failure to establish which of two registered nurses withdrew the blood does not preclude admissibility of the test results. 2. Bartel contends that the State failed to establish the time when the blood was drawn. He argues this is critical because it must be shown that administration of mannitol did not interfere with test results, and also be- cause time of blood drawing is critical to the accuracy of calculations made by experts to determine the degree of intoxication at the time of the accident. The time of the blood drawing is certainly a significant fact. Nurse Westfall-Marcus t e s t i f i e d t h a t the records did not disclose s p e c i f i c a l l y t h e t i m e o f t h e blood drawing, b u t only e s t a b - l i s h e d t h a t t h e I.V. was commenced a t 3 : 3 0 and t h a t m a n n i t o l was given t o Mr. Bartel at 3:35. She t e s t i f i e d that the r o u t i n e p r a c t i c e , which s h e f o l l o w e d and which was f o l l o w e d by other nurses in the hospital, would have required the withdrawal of t h e blood p r o m p t l y a f t e r t h e commencement o f t h e I.V. and p r i o r t o t h e g i v i n g o f m a n n i t o l . The t e s t i m o n y o f L e i l a n i Heuer, t h e l a b t e c h n i c i a n who c o n d u c t e d t h e b l o o d test, established that s h e completed h e r t e s t at 4:30 and t h a t it would h a v e t a k e n h e r n o t l e s s t h a n o n e - h a l f hour t o complete t h e t e s t . While t h a t e v i d e n c e d o e s n o t i n d i c a t e a s p e c i f i c t i m e , it d o e s c o n f i r m t h e p r o b a b i l i t y t h a t t h e b l o o d was withdrawn between 3 : 3 0 and 4 : 0 0 a.m. The f i n d i n g s on t h e part of t h e D i s t r i c t Court i n d i c a t e t h a t it concluded t h a t t h e b l o o d was drawn a t c l o s e t o 3 : 3 0 a.m., when t h e I . V . was begun. There i s c e r t a i n l y s u b s t a n t i a l evidence t o s u p p o r t that conclusion. There is in fact no evidence to the c o n t r a r y , b u t o n l y t h e s p e c u l a t i o n r a i s e d by M r . Bartel. We conclude that the argument of Mr. Bartel that there was m a n n i t o l i n t e r f e r e n c e must a l s o f a i l . 3. Bartel argues that the State's failure to demonstrate t h a t a non-alcoholic s o l u t i o n was u s e d for skin preparation is fatal to the test result's admissibility. Nurse W e s t f a l l - M a r c u s testified that the routine practice is to use Betadine, a non-alcoholic solution, when alcohol testing is anticipated. However, s h e c o u l d n o t s p e c i f i c a l l y remember t h e n a t u r e o f t h e s o l u t i o n u s e d on M r . Bartel. She did explain in detail the nature of the I.V. which was s t a r t e d , p o i n t i n g o u t t h a t a f t e r making a v e n i - p u n c t u r e , the needle i s withdrawn from t h e catheter with t h e tourniquet s t i l l on t h e arm s o t h e r e i s a s i g n i f i c a n t s p i l l i n g o f b l o o d on t h e f l o o r b e f o r e t h e s y r i n g e i s i n s e r t e d , a t which t i m e the 10 c c . I s of blood a r e taken out f o r t e s t i n g purposes. She c o n c l u d e d t h a t even i f a l c o h o l had been used t o swab t h e arm p r i o r t o t h e commencement o f t h e I . V . , s o much b l o o d was s p i l l e d t h a t s h e d i d n o t b e l i e v e t h e r e c o u l d h a v e b e e n any contamination. Dr. Mueller, forensic pathologist, testified that he had done studies on the effect of the use of i s o p r o p y l a l c o h o l swabs on t h e measurement o f e t h e l a l c o h o l . Dr. Mueller testified he had found the o n l y way it would affect the ethel alcohol result was if the needle was withdrawn t h r o u g h t h e s p o n g e w i t h t h e s u c t i o n s t i l l o n o r , i n o t h e r words, t h e doing of s o m e t h i n g d i s t i n c t l y abnormal o r incompetent i n withdrawing t h e blood. He testified that in the ordinary way of preparing an arm for example with alcohol, "isopropyl a l c o h o l simply d i d n o t g i v e measureable amounts o f a l c o h o l . " I n a d d i t i o n , he t e s t i f i e d t h a t t h e drug m a n n i t o l i s n o t a n i n t e r f e r i n g s u b s t a n c e w i t h t h e method o f alcohol testing used in the present case. We, therefore, conclude t h a t a f a i l u r e t o demonstrate t h a t a non-alcoholic s o l u t i o n was u s e d is not f a t a l t o t h e a d m i s s i b i l i t y of the blood t e s t . 4. Rartel argues that the State failed to show t h a t Bartel's abnormal body chemistries did not i n t e r f e r e with test results. However, the record contains nothing, indicating that body chemistries actually affected test results. 5. Bartel contends that the test results are i n a d m i s s i b l e because t h e S t a t e f a i l e d t o produce t h e o r i g i n a l t e s t machine p r i n t o u t and f a i l e d t o p r o d u c e q u a l i t y c o n t r o l records. F a i l u r e t o produce t h e o r i g i n a l test p r i n t o u t does not preclude admissibility of test results. S e e McAlpine, 6 3 4 P.2d at 7171-72, 38 St.Rep. at 1584. Heuer t e s t i f i e d t h a t E x h i b i t X was t h e l a b r e p o r t s h e p r e p a r e d by r e c o r d i n g test r e s u l t s . Further, she stated s h e would h a v e r e p e a t e d t h e t e s t if n e c e s s a r y t o g e t a n e r r o r - f r e e r e s u l t . Heuer and Spradlin testified that the hospital routinely followed q u a l i t y c o n t r o l procedures, preventive maintenance procedures and d a i l y c a l i b r a t i o n p r o c e d u r e s . W e f i n d no m e r i t i n t h e s e contentions. 6. Finally, Bartel argues t h a t t h e test r e s u l t s w e r e inadmissible because t h e State f a i l e d t o show t h a t t e s t i n g serum r a t h e r t h a n whole b l o o d d i d n o t a f f e c t t e s t r e s u l t s and f a i l e d t o show t h a t more t h a n one b l o o d sample was t e s t e d . O the contrary, Dr. n Muel l e r t e s t i f i e d t h a t t e s t i n g o f serum r a t h e r t h a n whole b l o o d was n o t s i g n i f i c a n t b e c a u s e i t c o u l d account for error of no more than 2-3 percent in test results. F u r t h e r , he s t a t e d t h a t m u l t i p l e t e s t samples w e r e unnecessary for accurate results. We reject these contentions. Despite Bartel's vigorous argument as to the significance of the alleged omissions in foundation testimony, Bartel has failed to establish any actual inadequacy in the blood test procedure which affects admissibility of t h e blood test r e s u l t s . I n McAlpine, we found it significant that the appellant had presented no evidence to support his contention that post-mortem blood c l o t t i n g seriously affected test results. We stated that a t most, t h e a p p e l l a n t had laid a b a s i s f o r a suggestion t h a t the condition of t h e victims' b l o o d had changed between t h e time of death and the time of drawing the blood. We concluded that " [sluch a suggestion goes to weight, not admissibility." 6 3 4 P.2d a t 1171, 38 St.Rep. a t 1583. I n a s i m i l a r manner, B a r t e l h a s a t most l a i d t h e b a s i s f o r a v a r i e t y o f s u g g e s t i o n s t h a t B a r t e l ' s blood t e s t r e s u l t s were i n some manner u n r e l i a b l e . Bartel h a s c i t e d numerous cases from f o r e i g n jurisdictions which h e a r g u e s e s t a b l i s h the inadmissibility of Exhibit X. These cases generally follow the rule established in Lessenhop v. Norton (Iowa 1967), 153 N.W.2d 107, which requires that before blood test results may be admitted in evidence, each of 9 specific factual requirements must be satisfied. These requirements include a showing of the time at which the blood was drawn and the identity of the person who drew the blood. 153 We do not follow the rule which requires that each of a list of facts be established as foundation for admissibility of blood-alcohol test results. Rather, we follow the McAlpine rule which requires that procedures accord with good practice in the field to assure reliability. Whether procedures accord with good practice in the field is a question to be decided based upon the facts and circumstances of a particular case and the expert testimony received. Having concluded that the record supports a finding that good medical practice was followed in this case, the alleged omissions in foundation raised by Bartel go to the weight of the testimony rather than its admissibility. We hold that the District Court did not err in admitting into evidence the results of Bartel's blood-alcohol test. Are the District Court's findings of fact number 6 through 8 supported by substantial credible evidence? Bartel's contention that findings of fact number 7 and 8 are unsupported by substantial credible evidence depends upon the inadmissibility of blood test results and upon Bartel's characterization of other evidence regarding his intoxication and impairment. We have concluded that the evidence of blood test results was properly admitted. We would also conclude there is additional evidence which supports these findings by the District Court. Gerald Cooper, one of Bartel 's drinking companions, c o u l d n o t remember how many d r i n k s B a r t e l had a t any o f t h e bars they visited. George Mitchell told investigating officer Schmauch that they had been drinking, barhopping. M i t c h e l l t e s t i f i e d t h a t B a r t e l had 9 o r more d r i n k s . Randy Merryman, a Lake County Deputy S h e r i f f who was p r e s e n t a t t h e s c e n e i m m e d i a t e l y a f t e r t h e a c c i d e n t , s t a t e d t h a t t h e r e was a very definite strong odor of alcohol on Bartel's breath. Karla Court, the registered nurse a t St. Ignatius Hospital who f i l l e d o u t t h e i n i t i a l r e p o r t on B a r t e l , w h i l e s h e s t a t e d s h e d i d n o t know f o r s u r e t h a t B a r t e l was i n t o x i c a t e d , s a i d t h e s m e l l o f a l c o h o l on him was " p r e t t y s t r o n g . " Dr. Cooney, treating physician at St. Patrick's Hospital i n Missoula, s t a t e d he has e x p e r i e n c e i n r e c o g n i z i n g i n t o x i c a t i o n , t h a t he s m e l l o f a l c o h o l i s v e r y c h a r a c t e r i s t i c of i n t o x i c a t i o n , and that the alcohol smell on Bartel was the basis for the n o t a t i o n on h i s r e p o r t t h a t B a r t e l was i n t o x i c a t e d . Although there was extensive testimony regarding the number o f d r i n k s B a r t e l had and how d r u n k h e a p p e a r e d t o b e , the t e s t i m o n y was c o n t r a d i c t o r y and none of t h e witnesses could state definitely how many drinks Bartel had o r how d r u n k h e was. The c o l l e c t e d testimony supports a finding t h a t B a r t e l had anywhere from 9 to 1 5 d r i n k s between 9:00 p.m. and 1:00 a.m. on the night of the accident. The District Court concluded i n finding of f a c t number 7 that Bartel had consumed "quite probably 12 to 15 drinks c o n t a i n i n g u n d e t e r m i n e d amounts o f s c o t c h w h i s k e y . " We hold there is substantial credible evidence to support this finding. This Court will not re-weigh c o n f l i c t i n g evidence. Marriage o f Smith (Mont., Dec. 13, 1 9 8 4 ) , No. 83-502, s l i p op. a t 4 . Extensive testimony was presented regarding Bartel's blood-alcohol level at the time of the accident and the degree to which he was impaired. The testimony on these points, as on most other key points in this case, was in sharp conflict. We conclude, however, that substantial evidence supports finding of fact number 8 with respect to Bartel's blood-alcohol level and degree of intoxication. Mr. Hutchinson, a clinical toxicologist with extensive experience in blood-alcohol testing and forensic toxicology, stated that based upon certain known factors it is possible to calculate with reasonable scientific reliability the blood-alcohol level of a certain individual at a certain time. Hutchinson then testified at length regarding the details of such a calculation as to Bartel. Hutchinson concluded that Bartel's blood alcohol level at 1 a.m. would have been from .lo3 to .213, within a reasonable degree of medical certainty. The blood-alcohol level was expressed as a range of values to take into account the unknown variables of individual elimination rate and individual absorption rate. This level would require that the individual drink around 18 to 21 ounces of 86 proof scotch. Hutchinson's testimony was corroborated by Dr. Mueller. Dr. Mueller further testified that at about .08 a person's visual acuity is significantly affected. The alcohol decreases peripheral vision, ability to recognize objects clearly, ability to focus, and ability to recover after being blinded by bright light. "Starting at about .08 the effect of alcohol in the system is to produce a kind of tunnel vision." At a .15 level, the vast majority of people are severely affected in driving a motor vehicle. Functions important in driving are impaired at .15 or less, even though there are no obvious signs of drunkenness apparent in those habituated to alcohol. Dr. Mueller stated that unless Bartel is very unusual, he would have suffered these effects. We hold there is substantive credible evidence to support t h e District C o u r t ' s finding of f a c t number 8 , t h a t "[alt the time of the accident, Bartel's blood s t r e a m was carrying between .lo3 and .213 percentage alcohol, which s e r i o u s l y i m p a i r e d h i s s e n s o r y and m e n t a l f u n c t i o n s . . . ." B a r t e l a l s o c o n t e n d s t h a t f i n d i n g o f f a c t number 6 , t h a t B a r t e l was "thoroughly familiar with t h e intersection," is n o t supported by s u b s t a n t i a l c r e d i b l e evidence. W e disagree. The record indicates that Bartel had driven past this intersection daily f o r many months prior to the accident. B a r t e l d e n i e d a t t r i a l t h a t h e had ever d r i v e n t h r o u g h t h i s i n t e r s e c t i o n o r t h a t h e had a f r i e n d i n S t . Ignatius.

Ignatius and h a v i n g d r i v e n t h r o u g h t h e i n t e r s e c t i o n . The t r i a l c o u r t s p e c i f i c a l l y found that Bartel had p r e v i o u s l y been in St. Ignatius on several occasions and that Bartel had done extensive t r a v e l i n g i n t h e area during t h e 6 y e a r s he l i v e d i n Ronan. We hold there is substantial credible evidence to support t h e District Court's finding of f a c t number 6, as w e l l a s f i n d i n g s number 7 and 8 .

See McAlpine v . Dahl ( 1 9 7 8 ) , 179 Mont. 23, 585 P.2d 1307; Jimison v. Unisted States (D. Mont. 1 9 6 7 ) , 267 F.Supp. 674, affirmed Jimison v. United States (9th Cir. We affirm the judgment of the District Court. We concur: --, The Honorable John M-. McCarvel, ~is&ict Judge, sitting in place of Mr. Justice John C. Harrison Mr. Justice John C. Sheehy, dissenting: I dissent from the unqualified acceptance by this Court and by the District Court of the blood test results in light of the record here. In my original dissent to the original opinion which has now been withdrawn, I contended that no foundation had been laid for the supposedly scientific tests of the blood alcohol concentrations here. I continue here in that dissent to the new opinion because at a minimum, for scientific test results a foundation should include the following factors: (1) that the persons engaged in the test were qualified; ( 2 ) that the machine used and its components were in proper condition; and (3) that the test was properly conducted. In this case, factors (1) and !3) have not been shown. It is incredible that the hospital chart does not show the precise time in which the blood was withdrawn from Bartel, nor the person who withdrew the blood. Thus we have no direct evidence as to how part of the test was conducted, a most important part, the drawing of the blood sample itself. A record of the time the blood was withdrawn from Bartel was especially important, because if the blood was taken after mannitol had been administered, at 3 :35 a.m. , then the test was subject to considerable doubt. Mannitol is a crystaline alcohol having a chemical makeup of C6HI4O6. If Bartel's blood was withdrawn before the mannitol was administered, but isopropyl was used to swab the location where the blood was withdrawn, there is still a problem (not admitted by the State experts) because isopropyl has a chemical makeup of C3H80. The chemical symbol for ethyl alcohol, the intoxicating agent in liquor is C2H60. This Court, like many another, has fallen prey to the pseudo-science of alcohol concentrations in the blood, urine or breath to determine drunkenness. With the advent of statutes using alcohol concentrations to define drunk driving, a holy mystique of a sort has grown up around the levels defined in those statutes. Courts and lawyers untutored in chemistry and in spite of their own experience accept these levels without question. They adopt the statutes as establishing a sharp cleavage between drunkenness and nondrunkenness. The assumption is embraced that one having an alcohol concentration of less than 0.10 is not drunk, but one having an alcohol concentration greater than 0.10 is drunk, even though that assumption belies their own personal observation. It is our common observation that some people carry their booze better than others. What is forgotten is that 0.10 alcohol concentration is an arbitrary figure, so arbitrary that proof of such an alcohol concentration without more, is in itself a crime in operating a motor vehicle. Section 61.-8-406, MCA. Until the legislative amendment in 1971, the former arbitrary figure was 0.15 alcohol concentration which would be half again as much alcohol in the blood. Section 32-2142, R.C.M. 1-947, amended Ch. 32, Laws of Montana (1971) . Now courts give greater probity to blood test results than to witnesses' observations of drunken persons, when the reverse should be true. To paraphrase the remark about pornography, we cannot define drunkenness, but we know it when we see it. In this case, there was a wealth of evidence about the amount of liquor consumed, the appearance, the eyes, the breath, the gait, the slurred speech, the lack of coordination that, had the District Court relied principally on these and not so heavily on the blood test results, I would then support its judgment. But because the blood test results weighed so heavily in its opinion in determining the intoxication of Ba-rtel, I am forced to dissent. I have never worshipped at the shrine of blood test results because they are for the most part a false idol, with feet of clay and the heart of a gas chromatograph. It is evident that the majority and the District Court have not thoroughly thought out the implications of blood test results, because each blithely accepts that Bartel had "a blood alcohol level of .I71 percent" or that at the time of the accident, Bartel's blood alcohol was "between .I03 and .213 percent." Percent of what? Blood alcohol levels cannot he defined in terms of percentage unless they are expressed in terms of percentage of weight or percentage of volume. Neither volume nor weight is met under the evidence in this case. The statute defining "alcohol concentration," for the purpose of this case, requires grams of alcohol per 100 milliliters of blood. Section 61-8-407, MCA. Grams are a measure of weight. Milliliters are a measure of volume. One cannot be expressed in terms of the other by percentage unless the substances being compared weigh exactly the same. Alcohol is lighter than water, because it floats on water. In fact, absolute alcohol has a specific gravity of 0.789, compared to water which has a specific gravity of 1. Blood is thicker than water, both socially and physically. I do not know the specific gravity of human blood but I suspect that it is greater than the specific gravity of water because my personal observation is that blood sinks in water. A cubic centimeter of alcohol, therefore, would weigh much less than a cubic centimeter of human blood. If we had a 100 milliliter mixture of water and alcohol of which the alcohol consisted of 1 percent by volume, the alcohol in the mixture would weigh 0.789 grams. If the alcohol in the same mixture constituted 1 percent by weight, the mixture would contain nearly 1.267 cubic centimeters of alcohol. Chemical-ly that is a vast difference. It is for that reason that the statute defining alcohol concentration now avoids references to percent, and relates instead to weight of alcohol per volume of blood. There is nothing, however, in the record before us to tell us what the so-called experts were talking about when they were referring to "percent" in determining blood alcohol levels. Lost in the murnbo-jumbo of the pseudo-science of blood alcohol tests is the fact that the tests involve infinitesimally small amounts. This is because statutory blood alcohol terms are couched in terms of metric measures, perhaps purposely so. Most Americans do not comprehend the relationship between metric measures and their U.S. equivalents. It may have helped if section 61-8-407, MCA, had defined "alcohol concentration" as the number of 0.035 ounces of alcohol per 6.1 cubic inches of blood. (A gram is 0.035 ounce.) We might be able to grasp then that if Bartel's blood alcohol level was 0.171 (assuming that 0.171 refers to grams) that his actual alcohol level per ounce was 0.005985 (0.171 x 0.035). Put another way, if each ounce of his blood was broken into a thousand parts, at a blood alcohol level of 0.171, six parts of that blood would constitute alcohol. The minuteness of those figures is lost in the metric system in the pseudo-science of blood alcohol levels. Minute -amounts of alcohol in the blood can cause intoxication. Minute amounts of other alcohol-related substances, if present, can seriously distort blood test results. I fear the weight given to blood test results, especially in civil cases where other and more convincing evidence of drunkenness is available. I fear the testimony of experts who testify that the margin for error in these tests is "2 to 3 percent." Two percent of 0.005985 is 0.0001197. I truly doubt that any machines available here are capable of measuring down to the ten millionth part. If we accept these statements without question, we have been overtaken by a form of doublethink in the guise of metric measures. Please do not answer that the hospital and doctors used the blood test results for their medical purposes, and therefore the results must be accurate. The medical people here did not need blood tests to determine that this man had been drinking. The nurse wrote "intoxicated" upon the chart the first moment she saw him. That observation was not based on blood tests. For these reasons, I would set a rigid foundational requirement for the admission of blood test evidence. Routine would not be enough. No perfect routine and no perfect machine can escape the impact of the imperfect human being. The majority in this case have elevated routine into infallability. 1 would reverse this case on the grounds that the District Court found evidence of intoxication based on the blood tests for which no proper foundation was laid and for the further reason that the blood test results do not relate to the statutory scheme of weight per volume of blood.
