Appeal from a judgment in favor of defendant Los Angeles Transit Lines, following an order sustaining its demurrer to plaintiff’s complaint for personal injuries without leave to amend. Appellant recovered judgment by default against defendants Paul and C. M. Garcia in the sum of $25,000, which remains wholly unsatisfied.
Respondent corporation operates a general street railway system in Los Angeles, and maintains wooden poles adjacent to the curbing on Whittier Boulevard near the corner of Spence Street, as part of its system. Appellant was standing on the sidewalk near one of these poles when a 1938 Plymouth automobile, negligently driven by Paul Garcia, collided with the pole. It broke a short distance above the ground and fell on appellant, causing severe injuries. Paragraph IV of the complaint alleges:' ‘ That at the time of the aforesaid accident, defendant, Los Angeles Transit Lines, carelessly and negligently maintained the aforesaid wooden pole in that said pole was rotten and its strength had become badly impaired by rot or termites; that said pole had been in a rotten condition for a long period of time which condition was known to defendant, Los Angeles Transit Lines, or by the exercise of reasonable care, should have been known to said defendant; that said Whittier Boulevard is a main and heavily traveled highway used by thousands of automobiles daily and said defendant, Los Angeles Transit Lines, in the exercise of reasonable care, should have anticipated that accidents would occur upon said highway and that automobiles would be likely to come *683 over the curbing and strike said pole and that if said pole was permitted to remain in a weakened condition as aforesaid that it would constitute a hazard to persons on the sidewalk and that the same was likely to be caused to fall upon or against said persons, and in particular, upon plaintiff; that the negligence of the defendant, Los Angeles Transit Lines, as aforesaid in maintaining said wooden pole in the condition above described together with the negligence of defendant Paul Garcia, in the operation of his said automobile contributed concurrently to cause the injuries to plaintiff hereinafter complained of. ’ ’
It was the duty of respondent to select and maintain poles sufficiently strong to withstand the ordinary strain of weather conditions and other tests of strength likely to be encountered along a busy highway.
(Keller
v.
Pacific Tel. & Tel. Co.,
It is respondent’s contention that, as a matter of law, any negligence of which it may have been guilty could not have been the proximate cause of plaintiff’s injuries. The termite-weakened pole, it is argued, furnished only the condition upon which the unforeseeable intervening act of Paul Garcia operated independently to cause the harm. In the cases upon which respondent relies in support of this proposition
(Sweet
v.
Los Angeles Railway Co.,
It is well settled that proximate causation is not always arrested by the intervention of an independent force. If the original negligence continues to the time of the injury and contributes substantially thereto in conjunction with the intervening act, each may be a proximate concurring cause for which full liability may be imposed.
(Gerberich
v.
Southern Calif. Edison Co.,
Respondent appears to contend that it is absolved from liability since it was not foreseeable that á motorist would negligently collide with its pole with such force as to cause it to fall upon plaintiff. However, in order to prevent an intervening act from being a superseding cause which will relieve the defendant of responsibility for his negligence, the law does not inevitably require that the precise act be foreseeable. Numerous cases have declared that if the defendant’s conduct exposes persons in the class to which plaintiff belongs to a foreseeable risk of injury, and his act or omission contributes substantially to injury of that nature actually occurring, he may be held liable notwithstanding the fact that an unforeseeable independent intervening act is a con

curring cause. (Prosser on Torts, pp. 369-372, and cases cited;
Sandel
v.
State,
The principle is recognized in section 435 of the Restatement of Torts: “If the actor’s conduct is a substantial factor in bringing about harm to another, the fact that the actor neither foresaw nor should have foreseen the extent of the harm
or the manner in which it occurred
does not prevent him from being liable.” (Emphasis added.) Thus, in
Carroll
v.
Central Counties Gas Co.,
Although language found in some of the California cases which discuss concurrent causes may not be entirely reconcilable with the views here expressed, we are satisfied that the decisions themselves are not in conflict with the principles we have stated. Without unduly extending this opinion we may say that the facts alleged in the present case distinguish it from cases where the intervening act was committed either deliberately or with knowledge of the existing danger
(Polloni
v.
Ryland,
Whether an intervening act is a concurrent cause or a superseding cause of the injury normally presents a question of fact.
(Stockwell
v.
Board of Trustees,
As we have seen, the allegations of the complaint were broad enough to admit of proof from which it could be found that respondent should have reasonably anticipated that its defective pole would be caused to fall and injure passing individuals such as plaintiff, either of its own weight, or by the forces of nature, or by the operation of any one of a number of other possible extraneous forces. If defendant failed to act as a reasonably prudent person to protect plaintiff and others from this hazard, it could be held liable for the injuries resulting from its occurrence. (See
Mars
v.
Meadville Tel. Co.,
The judgment is reversed with directions to the trial court to overrule the demurrer.
Wood, J., and Vallée, J., concurred.
Respondent’s petition for a hearing by the Supreme Court was denied May 25, 1950.
