Plaintiffs, who are husband and wife, brought this action to recover from defendants damages for personal injuries received by Mrs. Wohlenberg in an automobile accident alleged to have been caused by the negligence of defendants. The cause was tried before the court without a jury, and resulted in a judgment for defendants. From that judgment plaintiffs prosecute this appeal.
The injuries arose out of a three-car collision that occurred on the Bayshore Highway shortly after 5 p. m. on August 8, 1940. Mrs. Wohlenberg was riding in the back seat of an automobile being driven by Mrs. Berkes. The other two cars were being driven by defendant Betsy Adams and defendant Frank Malcewicz. The three automobiles were all proceeding in a southerly direction on the highway, and traffic was quite heavy. The highway is a main arterial, and has two lanes for traffic proceeding southerly. All three cars were in the inside, or fast lane. The Adams’ car was first in line, followed by the Berkes’ car and the Malcewicz’ car brought up the rear. Betsy Adams testified that she was traveling at forty to forty-five miles per hour when a truck, some distance ahead, pulled out of .the slow lane into the fast lane. This caused all the cars behind the truck to slow down. She stated that as a result she was forced to slow down very quickly. She was following another car at about a distance of one ear length. She admitted that she gave no hand signal to the cars following her, but she testified that her car was equipped with the usual red “stop” light operated by the brake pedal. When her ear had almost come to a stop, the Berkes’ car ran into the Adams’ ear, and then hit it a second time.
Maleewiez testified that he was driving some twenty to twenty-five feet behind the Berkes’ car at a speed of about twenty-five to thirty miles per hour; that he was driving a new Packard which was in perfect working condition; that the Berkes’ ear stopped very quickly; that it ran into the Adams’ car and he crashed into the Berkes’ car as the impact from the crash between that ear and the Adams car threw *511 the Berkes’ ear backward. The force of the impact with the Malcewicz’ car forced the Berkes’ car to again hit the Adams’ car. That corroborates the testimony of Betsy Adams that her car was hit twice by the Berkes’ car. That testimony was also corroborated by La Yonne Olds, a passenger in the Adams’ car.
Mrs. Wohlenberg testified that she was sitting in the back seat of the Berkes’ car; that Mrs. Berkes was going forty to forty-five miles per hour; that she noticed the traffic slowing down; that the Berkes’ ear came to an easy stop behind the Adams’ car without hitting it; that Mrs. Berkes had plenty of time to stop, and did so without hitting the Adams’ ear; that Malcewicz then crashed into the back of the Berkes’ car; that as a result of the impact she was thrown forward and backward suffering the injuries for which this action was instituted.
On this evidence the trial court found that neither defendant Adams nor defendant Malcewicz was guilty of any negligence proximately causing the accident. Appellants urge that the basic findings on negligence and proximate cause are not supported by the evidence. It is their contention that the trial court could have found that either Adams or Malcewicz was free from negligence, but that, under the evidence, it could not properly find that both were free of negligence. These contentions are unsound.
From the evidence the trial court could have found that the accident was proximately caused by the negligence of Adams, or of Berkes, or of Malcewicz, or by any combination of these drivers; or the court could have found that no one was negligent, that is, that the accident was unavoidable. The trial court did not find the cause of the accident. It was not required to do so. It found that it was not proximately caused by the negligence of Adams or Malcewicz. That means that the trial court was of the belief either, that the sole proximate cause of the accident was the negligence of Berkes, or that the accident was unavoidable. In either event, no liability would attach to defendants. Even if either or both defendants were guilty of some act of negligence neither would be liable unless such negligence proximately caused the accident. It is only in rare cases that an appellate court can say that a party was guilty of negligence proximately causing the accident as a matter of law. Normally, the question of causation is one of fact and not of law. These prin *512 ciples are elementary and have frequently been stated by the courts. (See cases collected 19 Cal.Jur., p. 732, § 139.)
Appellants urge that defendant Adams was guilty of negligence as a matter of law in failing to give a hand signal. Section 544, subdivision c, of the Vehicle Code provides that: “No persons shall stop or suddenly decrease the speed of a vehicle on a highway without first giving an appropriate signal in the manner provided in this chapter to the driver of any vehicle immediately to the rear when there is opportunity to give such signal.” Section 545 of the Vehicle Code provides in part: “The signals herein required shall be given either by means of the hand and arm or by a signal lamp or mechanical signal device of a type approved by the department. ...” Betsy Adams testified that she gave no hand signal, and appellants urge that this alleged violation of the signaling statute is negligence
per se. (Wright
