The defendant, convicted in a trial to the jury on a charge of speeding in violation of § 14-219 of the General Statutes, has appealed, assigning error in (1) the court's refusal to find certain material facts which were either admitted or undisputed; (2) the denial of the motion to set aside the verdict; (3) the denial of the motion for a new trial; and (4) certain rulings on evidence.
The jury could reasonably have found from the evidence the following facts: On June 28, 1961, at about 12:30 a.m., the defendant was traveling in a northerly direction on High Ridge Road, a public highway in Stamford. High Ridge Road is a four-lane highway, with two lanes in each direction. The traffic was light, the road was dry, the weather was clear, and the area was lighted. The defendant was operating a 1960 Ford Thunderbird which she had purchased in May, 1961. It was equipped with *Page 162 power brakes, power steering and puncture-proof tires. The car, which had only gone some 9000 miles at the time of the arrest, was in excellent mechanical condition. The posted speed limit on High Ridge Road is forty miles an hour. The defendant was clocked by a police officer for a distance of about a mile and three-quarters at a speed of between sixty and sixty-five miles an hour. In the course of the clock, the defendant passed through eight to ten intersecting streets and "passed a couple of vehicles heading north." The defendant was familiar with the locus, since she traversed High Ridge Road five or six times a day.
We first consider the ruling of the trial court in excluding a question designed to elicit the opinion of the police officer as to whether or not the speed at which the defendant was traveling during the course of the clock was unreasonable under all the circumstances. It is conceded that the police officer is an expert on the subject of speed of motor vehicles. "The rule is well established that the opinion of experts cannot be received in evidence where the subject-matter of inquiry may be presumed to lie within the common experience of all men of ordinary knowledge. . . . If the facts can be placed before a jury and are of such a nature that jurors generally are just as competent to form opinions in reference to them and draw inferences from them as the witnesses, the opinions of experts cannot be received. The fact that the expert witness may know more of the subject and better comprehend and appreciate it than the jury is not sufficient to warrant the introduction of his testimony." Rogers, Expert Testimony (3d Ed.) pp. 50, 51. "The fact that the [expert] witness may have been more skilled and experienced than the jurors does not of itself justify expert testimony. Nor will expert testimony be permitted on the ultimate facts to be *Page 163 determined by the jury, as, for instance, . . . whether an automobile can be safely operated under certain conditions." 15-16 Huddy, Automobile Law (9th Ed.) § 226, p. 406; 9c Blashfield, Automobile Law and Practice (Perm. Ed.) § 6312; 20 Am. Jur., Evidence, § 782; see Reed v. Edison Electric IlluminatingCo., 225 Mass. 163, 167 (whether "it was or was not `safe and proper' to operate the car under the circumstances existing at the time, was a question of fact for the jury and not of expert opinion, and the answer of the witness . . . should not have been received"). "[T]he standard actually applied by the trial judges of today approaches more nearly the principle espoused by Wigmore, namely that the opinion should be rejected only when it is superfluous in the sense that it will be of no value to the jury." McCormick, Evidence, p. 23; 7 Wigmore, Evidence (3d Ed.) § 1918, citing Sydleman v. Beckwith,43 Conn. 9, 12; see Stephanofsky v. Hill,136 Conn. 379, 385, and cases cited. This is the kind of statement by the witness which amounts to little more than an expression of his belief as to how the case should be decided; it would virtually place him in the jury box to weigh the evidence. See Smith v.Hickenbottom, 57 Iowa 733, 738; 2 Jones, Evidence (5th Ed.) § 417. The ruling was within the discretion of the trial court. "The judge at the trial is in so much better position than an appellate court to determine when a witness should be permitted to give opinion evidence that his rulings should be accepted save in the most exceptional circumstances." Model Code of Evidence rule 401, comment c. "The rule also precludes opinions characterizing acts or conduct as . . . reasonable or unreasonable . . . ." 32 C.J.S., Evidence, pp. 83, 84 n. 37. The court did not err in excluding the opinion of the police officer.
The defendant also assigns as error the court's refusal to permit her to examine the arrest sheet *Page 164 which was made out by the police officer at the time of the arrest. It was a statement prepared by the arresting officer for the purpose of enabling the prosecuting attorney to perform the duties of his office. "[A]n adverse party has no right to demand its production." State v. Zimnaruk, 128 Conn. 124,127, and cases cited. There was no evidence that the statements in the arrest sheet would contradict the testimony of the police officer. If the defendant believed there were material inconsistencies or contradictions in the statement, it was permissible to move for its inspection by the presiding judge. "Refusal of the accused's request for production of a writing in the prosecutor's possession may be based upon the failure to lay a proper foundation for requiring production by taking the necessary preliminary steps and by showing that the statement is at variance with the writer's testimony; the accused's request cannot be a mere fishing expedition." Note, 156 A.L.R. 345, 350, and cases cited. We cannot find error in the ruling of the trial court.
A further assignment of error is the court's refusal to grant a new trial on a claim of newly discovered evidence. It is alleged that the summons which had been issued to the defendant stated that she was operating her motor vehicle at sixty miles an hour; the original summons indicated she had been driving between sixty and sixty-five miles an hour. The summons was given to the defendant at the time of her arrest. It was in her possession at all times throughout the trial. The defendant by her own testimony conceded she was traveling at fifty-five miles an hour. "The granting of new trials for newly-discovered evidence will be allowed only where it is clear that the case does not run counter to our established rules. One of these is that the new evidence must be `sufficient to turn the cause in favor of the applicant.'" Apter v. Jordan, 94 Conn. 139, *Page 165 141. "Newly-discovered evidence which is merely cumulative, or which impeaches the reputation or credibility of a witness, will not suffice ordinarily to grant a new trial, and never unless it appears reasonably certain that injustice has been done in the judgment rendered, and that the result of a new trial will probably be different." Id., 143. "[A]nd upon such an application the court compares the old testimony with the new and decides, in the exercise of a sound discretion, whether injustice has probably been done, and whether the newly discovered evidence is likely to change the result."Levine v. Union New Haven Trust Co., 127 Conn. 435,440. We cannot say upon this record that the discretion of the court was abused. See Kliarsky v.Eastern Greyhound Lines, Inc., 116 Conn. 649, 651.
We next consider the assignment of error that the evidence did not warrant a conviction of speeding. "The degree of excess of speed over the posted limit is an important factor to be considered by the trier in determining whether, under all the circumstances, a motor vehicle has been operated at a speed greater than was reasonable." State v.Gordon, 144 Conn. 399, 402. The defendant conceded that she was operating her automobile at least fifteen miles an hour in excess of the posted limit. She was clocked at a speed of between twenty and twenty-five miles an hour in excess of the posted limit. "It is an open question for the trier to decide whether, in any given case, the speed is actually unreasonable under all the circumstances." Ibid. "Its answer involved weighing conflicting evidence and passing upon the credibility of witnesses and testimony, and it [whether the speed was unreasonable or not] was thus brought distinctly and peculiarly within the jury's province." Radwick v. Goldstein,90 Conn. 701, 706. There is nothing to indicate a prejudice on the part of the jury or improper influence *Page 166 affecting them. There was reasonable ground appearing in the evidence upon which the jury might have reached their conclusion. In these circumstances, the verdict cannot be set aside. State v. Hayes, 127 Conn. 543, 554.
There is no error.
