The general nature of this action to recover damages arising out of a traffic accident was stated on a former appeal, Campbell v. Clark, 10 Cir.,
Error is predicated upon the action of the court in admitting in evidence the testimony of Ralph H. Snyder,
*768
an expert witness. The witness was not at the scene of the accident, either at the time or later. He examined photographs taken at the scene of the accident shortly after the collision, made a study of the facts and circumstances disclosed, and expressed an opinion respecting primarily the point of the impact between the truck and the automobile, the angle of each vehicle at the time of the impact, and other related matters of secondary importance. It is the general rule that expert testimony or conclusions to be drawn from facts and circumstances are inadmissible in instances where the normal experience and qualification of laymen jurors enable them to draw proper conclusions from given facts and circumstances. Grayson v. Williams, 10 Cir.,
More often than otherwise, the question of the admissibility of expert evidence in actions for damages arising out of highway accidents has involved testimony of members of highway patrol, sheriffs, deputies, police officers, or other public officials who went to the scene after the accident had occurred, viewed the facts and circumstances, and then gave their opinion as to what happened. The courts are sharply divided numerically and otherwise respecting the admissibility of evidence of that kind. See notes to Tuck v. Buller,
This accident occurred late Monday afternoon. It was snowing and there was evidence tending to show that earlier in the day the highway was slick with ice at a point not far from the place of the accident. The truck driven by appellant was going south, and the automobile driven by appellee was going north. Appellant was the only eye witness to the accident who testified. The substance of his testimony was that he was traveling at about thirty-five or forty miles per hour; that the automobile was about one hundred yards away when he first saw it; that it was coming on its side of the road; that all at once it fishtailed to the left; that it then swerved to the right; that after swerving to the right, it instantly or a second later headed right straight at him; that the impact of the accident occurred on his side of the road; that the truck ended up in the ditch on the west side of the highway; and that the automobile ended up in a southwesterly fashion across his lane of traffic. He made statements concerning the circumstances of the accident which were not in complete harmony with each other and in some material respects were in conflict with his testimony. Appellee was a witness in the case. She testified that her automobile was in good condition; that she had no trouble controlling it; that she had reduced her speed on account of the snow; that she was driving about twenty miles per hour; that the snow reduced her visibility; that she could see the road but could not see very far ahead; and that she was on her own side of the road. But she did not have any recollection of the accident. Her last recollection was when she came over a hill about one-half to three-quarters of a mile south of the point where the accident occurred; and the next thing she knew was Tuesday night when she was told of the accident. The expert witness was a safety engineer and also was known as an accidentologist. At the time of giving his testimony, he was engaged in three types of business at Oklahoma City, Oklahoma. They were all testing. He conducted a laboratory setup where drivers were tested to ascertain whether they were competent to drive trucks or equipment they were being hired to drive. He conducted a safety service company which consisted of a slide proposition. Through it, he furnished investigators and attorneys the braking distance of vehicles under all conditions, and various technical data for use in investigating accidents. And he conducted what he called an accident analysis laboratory. In connection with that operation, attorneys and others sent him their accident cases for analysis. Sometimes he was called to the scene of the accident if he was available or it happened close by; but as a rule, attorneys sent him cases and he made investigations and analyses for them. He had been investigating highway accidents many years and had testified as an expert in many cases. He had read extensively writings relating to investigations of accidents and he had written articles for publication in technical magazines and in the press relating to the analysis of accidents. He testified that when automobiles collide on the highway there are two impacts, and he referred to them as the first impact and the secondary impact. He commented upon the response of vehicles to such impacts. He explain
*770
ed the difference in weight as a factor in determining the behavior of vehicles in response to the impact. He referred to kinetic energy as a factor in molding circumstances developing in the course of highway accidents. He discussed the energies of moving vehicles in point of being dissipated by the initial impact. He said that in a collision, the vehicles may come clear off the ground, and that they then may turn one way or the other or assume one position or the other depending upon whether they met head on or at an angle. He discussed the difference in metals at different parts of auto-biles as indicating a clue respecting the position of vehicles at the time of the collision. And he discussed other matters of a technical nature. Photographs used by the witness in making his study of the collision were introduced in evidence. He testified that he had not been able to determine how the vehicles arrived at any particular location on the highway prior to the point of the collision; that his findings were from the instant of impact afterward; that in his opinion they came together at an angle; and that in his opinion the truck was angled to its right and the automobile to its left at the instant of the impact. He made it clear that in reaching such conclusion, he took into consideration the weight of the two vehicles, the dominance in point of force of the truck, the points of damages to the vehicles, and the respective positions at which the vehicles came to rest. In Virginia, similar testimony given by the same expert witness was held to be inadmissible for the reason that it tended to usurp the function of the jury. Venable v. Stockner,
Complaint is made that the court erred in giving to the jury an instruction on unavoidable accident. The substance of the argument is that the evidence was confined to negligence and that, therefore, no instruction should have been given relating to unavoidable accident. Meneley, by Myers v. Montgomery,
Finally, it is urged that the court should have given certain requested instructions. The brief of appellant purports to quote three requested instructions. But they do not appear in the record, and therefore, no question relating to their refusal is open to review.
The judgment is affirmed.
