delivered the opinion of the court.
This action was instituted to recover damages for personal injuries and the destruction of property occasioned by a collision between plaintiff’s motorcycle and defendant’s automobile. Plaintiff prevailed in the lower court, and defendant appealed from the judgment and from an order denying a new trial.
Main Street, running north and south in the city of Butte, crosses Granite Street at right angles in the business district of the city. Plaintiff was riding upon his motorcycle going *398north on the east side of Main Street, and crossing Granite Street, when Arthur Leland, driving one of defendant’s taxicabs south on the west side of Main Street, turned east on to Granite Street, where the two vehicles collided, causing the damage of which complaint is made. At the time there was in force an ordinance regulating vehicle -traffic on the streets, and plaintiff charges that Leland violated the ordinance (1) in exceeding the speed limit, (2) in failing to keep to the right when he turned from Main Street on to Granite Street, and (3) in failing to have the taxicab under control while on the intersection of the two streets. There is substantial evidence tending to support each of these charges, and, in the light of the jury’s verdict, it must be accepted as established for all purposes of these appeals that defendant’s agent ¡vas guilty of negligence.
The ordinance fixed eight miles per hour as the maximum [1] speed at which either plaintiff or Leland was permitted to travel upon the intersection of the streets, and a violation of the ordinance constituted legal negligence. (Neary v. Northern Pac. Ry. Co., 41 Mont. 480, 110 Pac. 226.)
Plaintiff testified that he was upon the intersection 'of the two streets when he first saw the taxicab, and, concerning the rate at which he himself was traveling at the time, said: “I was going north; I had just entered into Granite Street, probably fifteen feet. I was within six feet of the east side of Main Street. My intended destination was Mathews, in "Walkerville. I was going up Main Street at my usual rate of speed at that time, as far as the city was concerned. My usual rate of speed traveling up Main Street at that time was anywhere between ten and twelve miles an hour; maybe was going ten miles. * * * I will say-I was going about eight or nine miles, not more than that. I will say I was going eight miles an hour. I couldn’t say exactly what I was going, but no faster than nine if I was going nine, but I will say I was traveling at no more than eight. * * * I was not exceeding nine miles an hour.” He testified further that he was about eighty feet from the taxicab when he first realized *399that he was in a position of danger, and that he did not do anything except to continue at the same speed at which he was traveling, though he tried to increase his speed, but was unable to do so.
In each of several instructions the court submitted a par-[2-4] ticular provision of the ordinance—the provision limiting the speed at street intersections by instruction 4—and in each instance directed a verdict for plaintiff if the jury found that Leland had violated the particular provision, and as a proximate result plaintiff was injured. Objection was made that each of these instructions ignored the question of plaintiff’s contributory negligence, but the objection was overruled, and these rulings furnish the basis for the contention that the cause' was submitted to the jury upon an erroneous theory.
The effect of the ruling was a refusal to submit the question of contributory negligence. Apparently the court proceeded upon the theory that, since contributory negligence was not pleaded as a defense, it could not be made available to the defendant, and that is the general rule in this jurisdiction; but a corollary to the rule, rather than an exception to it, is equally well established, viz.: “Whenever the plaintiff’s own ease presents evidence which, if unexplained, would make out prima facie contributory negligence on his part, there must be further evidence exculpating him, or he cannot recover. ’ ’ (Harrington v. Butte, A. & Pac. Ry. Co., 37 Mont. 169, 16 L. R. A. (n. s.) 395, 95 Pac. 8.) In other words, whenever from plaintiff’s own case contributory negligence is fairly inferable, defendant may avail himself of the defense even though it is not pleaded.
The violation of the speed ordinance by Leland. constituted negligence for which the defendant, his employer, might be charged, but equally so the violation of the same ordinance by plaintiff constituted negligence, and, if it may be said that Leland’s violation was a proximate cause of the collision, so likewise might it be said that plaintiff’s violation was a contributing proximate cause. (Melville v. Butte-Balaklava Copper Co., 47 Mont. 1, 130 Pac. 441.)
*400Negligence cases in which, liability may be determined as a matter of law are exceptional. As a general rule, the issue of negligence or contributory negligence must be decided by the jury under appropriate instructions.
By applying these rules to the facts narrated, it becomes apparent at once that the trial court erred in adopting the theory upon which the cause was submitted. If the jury might have concluded from the testimony of the plaintiff that he was exceeding the speed limit, they would have been authorized to deny him any relief, for our statute declares: “Between those who are * * * equally in the wrong, the law does not interpose.” (Sec. 8753, Rev. Codes 1921.)
Plaintiff’s testimony quoted above is equivocal in the extreme, but the.jury were not required to adopt the interpretation which would absolve him from the imputation of negligence. They might have accepted as true his statement that he was going anywhere between ten and twelve miles an hour. The least that can be said upon the subject is, it was not the province of the court to decide which of the conflicting statements is true.
It is beside the question' that an appropriate instruction on contributory negligence was not tendered. If such an instruction had been requested and given, it would have been in direct conflict with each of the instructions referred to above. Those instructions are not merely incomplete. .Each of them is essentially erroneous in view of the plaintiff’s own testimony. The issue of contributory negligence should have been submitted to the jury.
We deem it unnecessary to consider the other assignments.
The judgment and order are reversed and the cause is remanded for a new trial.
Reversed cmd remanded.
Mr. Chief Justice Brantly and Associate Justices Cooper and Galen concur. Mr. Justice Reynolds, being absent, takes no part in the foregoing decision.
