Plaintiffs, two injured and the heirs of one killed in a collision with defendants’ truck, appeal from judgment entered on a jury verdict in favor of defendants. The issues relate primarily to certain instructions.
We construe the evidence and all reasonable inferences therefrom most strongly in favor of respondents.

v.
Antoyan,
Around 1:15 p.m. defendant Nunnelee was driving a truck with two trailer attachments in the right or slow lane, also going north. As he rounded a curve he first saw, some 300 to 500 feet ahead, the Cadillac traveling in the left or fast lane going what be thought to be about the same speed as his truck. The truck was going from 48 to 50 miles an hour; it *773 was in ninth gear and controlled by a governor which prohibited speed over 50. The Cadillac then reduced its speed and the truck began to overtake the Cadillac, both vehicles remaining in their respective lanes; there was no ear between them. He did not notice anything unusual about the manner in which the Cadillac was being driven, or whether it had a flat tire or if its right side was down. At all times he was looking at the road ahead but the next time he particularly noticed the Cadillac he was within 3, 4 or 5 car lengths of it; the Cadillac was going 20 or 25 miles per hour. At this time and for “a matter of a second, maybe two,” he looked in the rear-view mirror attached to the driver’s side of the truck to determine if it was safe to pass the Cadillac; he did this as a precaution to make sure that no ear behind him would attempt to go around the truck through the gap between it (in the right lane) and the Cadillac (in the left). When he glanced back to the road “the Cadillac was just coming across the white line” from the left lane into the right lane directly in front of the truck; he was “right on it” and at that instant he “yanked at the wheel and hit at the brake” but before it could take effect the collision had occurred. The left front tire of the truck collided with the right-rear bumper of the Cadillac, and jumped up over it and into the trunk of the Cadillac. Damage to the Cadillac extended from the right rear and the right-rear side forward to the right-front door; the front-right side, the front and left-front side appear to have been undamaged by the impact. (Exs. 12,14.)
One Wilkinson, northbound behind the truck, witnessed the accident; he saw the Cadillac traveling in the left fast lane, then suddenly cut over into the right lane directly in front of the truck.
Jones, a tire expert, examined the flat tire in the Cadillac trunk (the first flat Sievers had in Los Angeles) and determined it could have been repaired with only minor effort. He also examined the flat tire on the Cadillac at the time of the accident and testified that it contained a double tube; that the blowout was caused by the outer tube rubbing against the road through a small portion of the tire which had worn out exposing a thin layer of ply fibers and the outer tube; that the outer and inner tubes revealed that the Cadillac was driven on the flat tire 10 to 25 miles—based on the fact that the tube, made of natural rubber, a strong material, required at least 10 miles of flat riding before it could become as shredded as it was; that the tire and rim were not as dam *774 aged in proportion to the outer tube because the double tube formed a large mass of rubber providing a cushioning effect inside the tire preventing the tire from being compressed entirely flat when driven; and that any sudden acceleration or deceleration of speed would cause the car to swing in the direction of the flat tire—in this ease, to the right because the right-rear tire was flat.
Harper, a physicist, examined the tire marks on the highway and correlated them with various parts of the Cadillac and truck; he found the physical evidence (damage to the vehicles and debris at the scene) to be consistent with the testimony advanced by both sides.
Around 1 p.m., Ernest Costa, a laborer in a beanfield near the highway, heard an unusual thumping sound, like that of a car going by with a flat tire at “a pretty fast rate of speed,” coming from the northbound lane of the highway; he then proceeded to the scene of the accident where he saw the Cadillac with the flat tire.
The main evidence pointing to how the collision occurred— the lane in which plaintiffs traveled, how fast Sievers drove, how far they rode on the flat tire and whether the Cadillac swerved in front of defendants’ truck—is in irreconcilable conflict. The only undisputed fact concerning the accident is that defendant Nunnelee was at all times traveling in the slow right lane where the collision occurred. Among the four occupants of the Cadillac only Sievers testified; there were no other eyewitnesses who testified except defendant Nunnelee and Wilkinson. Plaintiffs’ version of the accident is based on Sievers’ testimony that he drove the Cadillac in the slow right lane, partly on the shoulder, in slow gear at a speed of 5 to 8 miles per per hour for approximately 7/10ths of a mile; that he first saw defendants' truck in his rear-view mirror when the truck was 400 or 500 yards behind him, just rounding a curve; that a little later he saw the truck several car lengths behind and motioned defendant Nunnelee to pass; and that when he glanced in his mirror a third time he saw defendants’ truck, which had not slackened its speed, upon him and the impact occurred from the rear without warning. While Sievers, a Mr. Kutbach and a highway patrolman testified that Nunnelee, after the accident, said he had not seen the Cadillac, Nunnelee denied making such a statement.
After hearing the two versions the jury, as it had a right to do, rejected Sievers ’ story and accepted as true the testi

mony of defendant Nunnelee and his witnesses. We will not disturb the factual determination of the jury, for it is not the province of this court to evaluate conflicting evidence.

v.
Berniker,
There is no merit to appellants’ first contention that neither the pleadings nor the evidence supports the instructions on contributory negligence. The issue of imputed negligence having been abandoned (the jury was properly instructed that the negligence, if any, of the driver of the Cadillac cannot be imputed to the passengers), and contributory negligence having been specifically and properly made a separate defense in the pretrial order

v.
Los Angeles Transit Lines,
*777 Appellants’ next contention is that it was prejudicial error to instruct the jury on the defense of assumption of the risk. There is merit to their claim and, for' the reasons hereinafter set forth, we hold the doctrine to be in-' applicable to the facts in this case and the giving of instructions on assumption of the risk to be error.
“The doctrine of assumption of risk is based on the theory that there has been a voluntary acceptance of a risk, and such acceptance, whether express or implied, requires knowledge and appreciation of the risk.”
(Hayes
v.
Richfield Oil Corp.,
“It is now well established in California that the doctrine of assumption of risk has two requisite elements: (1)" Knowledge and appreciation of the
danger
involved by the person in question; and (2) his voluntary acceptance of the risk.
(Gomes
v.
Byrne,
Under the evidence in this ease the defense of assumption of the risk can arise, if at all, only from defendant Nunnelee’s version of the accident; and while it reveals that plaintiffs must have known and appreciated their position in riding in an unsafe car disabled by a flat tire, out in the fast lane of traffic in a two-lane highway going, at what under the circumstances was, an excessive speed, it shows neither the hazard, danger or risk to which plaintiffs were subjecting themselves, and for which defendants were responsible, nor that plaintiffs had knowledge or appreciation of any such danger. As to what plaintiffs were assuming, was it the risk incident to Sievers’ negligent conduct? If so, this might be a defense to an action against Sievers, but Sievers is not a defendant herein. Was it then a risk incident to defendant Nunnelee’s negligent conduct? But again, Sievers’ testimony, which would warrant a finding of defendants’ negligence, shows no facts material to the defense of assumption of the risk; on the other hand, defendant Nunnelee’s testimony shows no negligence on his part.
The defense is predicated on “the plaintiff’s consent to relieve the defendant of an obligation of conduct toward him, and to take his chances of harm from a particular risk.” (Prosser on Torts (2d ed. 1955) p. 303), the theory being that defendant’s conduct involves certain danger of risk which plaintiff voluntarily accepts.
(Morton
v.
California Sports Car Club,
The evidence not being sufficient to warrant instructions on assumption of the risk, it was error to instruct thereon. Whether it was prejudicial to the rights of plaintiffs must be determined in the light of the unusual factual situation pre
*780
sented by this case to the jury and instructions given on the defense of contributory negligence. In accord with settled rules controlling the applicability of the doctrine, plaintiffs could have assumed the risk only if they had actual knowledge of, and consented to, the defendants’ specific negligent conduct; the risk assumed must be one created by negligent conduct on the part of defendants. But, under the facts of this case and from the instructions herein given, the jury could have reasonably inferred that if plaintiffs knew of some danger in riding in the Cadillac (even that created by Sievers ’ negligence) they would be barred from recovery regardless of the reasonableness of their conduct.

v.
Malinoff,
Our conclusions render it unnecessary to consider the other assignments of error set out in appellants’ opening brief. Por the foregoing reasons the judgment is reversed.
Wood, P. J., and Pourt, J., concurred.
A petition for a rehearing was denied July 6, 1964, and respondents’ petition for a hearing by the Supreme Court was denied August 5, 1964.
