The defendant appeals from a judgment in favor of the plaintiff.
The cause of action was for damages alleged to have been caused by the negligence of the defendant, resulting from a collision between the plaintiff, who was riding on a motorcycle, and a truck belonging to the defendant, driven by one of its servants, at the intersection of D Street and Sixth Street, in the city of Eureka. D Street runs north and south; Sixth Street runs east and west. Plaintiff was going east on Sixth Street toward D Street. The truck, going north on D Street toward Sixth Street, reached the intersection first. It was traveling on the driver’s left-hand side of the center line of D Street, contrary to law. The truck was twenty-one feet long and weighed over nine thousand pounds. When the front end of the truck was a few feet north of the center line of Sixth Street, on the intersection, it suddenly stopped. The complaint alleged that the driver gave no signal of his intention to stop. The plaintiff was going at a speed of about thirteen or fourteen miles an hour and was expecting to pass to the rear of the truck in crossing the intersection. The motorcycle struck the truck immediately in front of the rear wheel about seven feet from the rear end thereof. The plaintiff’s contention is that the collision was caused by the negligence of the truck driver in suddenly stopping the truck without giving any adequate signal of his intention to do so. The defendant contends that it was caused by the plaintiff’s contributory negligence in traveling along the street at an unlawful rate of speed, and also in approaching the truck, at a speed so fast that he would be unable to stop it or turn it in time to avoid the collision, in case it had suddenly stopped without warning.
This renders it unnecessary to consider at all the parts of the argument for the defendant based on statements in the testimony favorable to the defendant but inconsistent with evidence on the same point favorable to the plaintiff. Every fact in favor of the plaintiff which is supported by substantial evidence tending to prove it must be taken as true.
The second question and answer aforesaid were as follows: “Would plaintiff have collided with said motor-truck and sustained the injury complained of regardless of whether the operator of said motor-truck had or had not given any warning or audible or visible signal of his intention to stop said truck?” Answer: “Yes.”
Defendant claims that this answer was in effect a finding that the truck driver did give an audible and visible signal of his intention to stop, and that it is inconsistent with any finding of the jury that the defendant’s truck driver was negligent.
Instruction 20 was as follows:
[5] “ The presumption is that every man obeys the law and the presumption in this case is that the plaintiff was *25 traveling at a lawful rate of speed and on the proper side of the highway at all times. This presumption is in itself a species of evidence and it shall prevail and control your deliberations until and unless it is overcome by satisfactory evidence.”
The defendant claims that this is erroneous. We think it is correct. The rule that contributory negligence of the plaintiff must be alleged in the answer, or it will not be available to the defendant as a defense, is based on this presumption. So, also, is the rule that the burden of proving it by a preponderance of the evidence is on the defendant. The code expressly declares that this presumption is disputable, that it “may be controverted by other evidence,” and that unless so controverted the jury is bound to find in accordance with it. (Code Civ. Proe., sees. 1961, 1963, subds. 1, 33.) The instruction is, therefore, strictly in accordance with the code on the subject.
We find no errors sufficient to authorize a reversal.
The judgment is affirmed.
