The heirs of Albert Ferroggiaro brought an action for damages resulting from the death of Ferroggiaro when the automobile in which he was riding as a passenger driven by Edward Silverman collided with one operated by Walela May Bowline. The plaintiffs named as defendants both Silverman and Bowline, charging each with negligent operation of their respective automobiles, and also named as defendants Charles Tipri, and his employer, the Petri Brothers of Tracy. So far as the liability of these last named defendants is concerned, the amended complaint alleges that the accident happened at the intersection of Highways 99 and 399 in Kern County on October 4,1954; that on that day, Tipri, in the course of his employment and in an automobile owned by his employer, was driving “in the vicinity” of the named intersection; that he “so carelessly and negligently drove and operated said automobile as to cause the same to leave the roadway and collide with the mechanism that controls the traffic signals at said intersection, thereby causing said traffic signals to cease to function”; that immediately prior to these acts the traffic at the intersection was controlled by properly functioning signals; that shortly thereafter the Silverman and Bowline cars approached the intersection at right angles; that the two ears collided; that both Silverman and Bowline were negligent and that such negligence “concurred proximately with the aforesaid carelessness and negligence of . . . Tipri, to cause the said respective vehicles to collide violently with each other,” resulting in the death of Ferroggiaro.
Bowline and Silverman answered and cross-complained. Bowline named Silverman, Tipri and Petri Brothers of Tracy as cross-defendants, while Silverman named Bowline, Tipri and Petri Brothers of Tracy as cross-defendants. Each *762 charged the other with negligence, denied their own negligence, and both charged Tipri with concurrent negligence. The cross-complaint of Bowline alleges the negligence of Tipri substantially as did the Ferroggiaro complaint except that it is alleged that just before the accident Tipri negligently and carelessly drove his car so as to cause it to leave the roadway “and collide with a pole on which electric current was run that affected the mechanism which controlled the traffic signals at said intersection and the lights in and about the said intersection, thereby causing the said traffic signals to cease to function and causing the electric lights in and about the said intersection to go out.” The damages resulting from the collision are alleged to have been the “proximate result of the aforesaid carelessness and negligence” of Tipri and Silverman.
The answer and cross-complaint of Silverman charges Bowline and Tipri with concurrent negligence in substantially the language of the Ferroggiaro complaint.
Tipri demurred generally and specially to the complaint and to the two cross-complaints. The trial court sustained the demurrers without leave to amend. Judgment was entered accordingly, and the Ferroggiaros, Silverman and Bowline appeal. The ease is simply one in which each appellant charges Tipri with negligence in colliding with the power pole and thus extinguishing the nearby traffic lights, and then charges that this negligence concurred with the negligence of other designated persons to cause the accident. On the present appeal the sole question is whether the charged negligence of Tipri was a proximate cause of the accident, or whether the intervening negligence of some third party, as a matter of law, broke the chain of causation. Possible contributory negligence of Bowline and Silverman is not now involved, contributory negligence being a matter of defense.
Appellants argue that in negligently colliding with the pole and extinguishing the traffic lights Tipri breached a duty of care owed to a class of which appellants were all members, namely, those using the highway at the intersection in question, and that even if Bowline and Silverman were subsequently negligent, such negligence was, at most, concurrent and did not break the chain of causation. Appellants point out that proximate cause and foreseeability are normally questions of fact and not of law. Respondent argues that, as a matter of law, the charged negligent acts of Bowline and Silverman broke the chain of causation because it was not legally foreseeable that the negligence of Tipri would be *763 followed by the negligence of Bowline and Silverman. It is argued, therefore, that respondent did not foresee and necessarily could not have foreseen the results of his negligence. Under such circumstances, it is urged, proximate cause becomes a question of law.
There are certain well settled general principles that govern this appeal. A defendant may be negligent for failing to guard against an intervening cause which in ordinary human experience is reasonably to be anticipated or which the defendant has reason to anticipate. In other words, the risk created by the original act of negligence may include the intervention of the foreseeable negligence of others. (Prosser on Torts, 2d ed., p. 268 et seq.) The fact that the intervening act of a third person is a negligent one will not make it a superseding cause of harm to another for an injury which the original actor helped to bring about, if the original actor at the time of his negligent conduct should have realized that a third person might so act.

v.
Santa Catalina Island Co.,
In the present ease the only question now presented is whether or not, when Tipri negligently collided with the power pole, and thus extinguished the traffic signals and other lights at the intersection, was it reasonably foreseeable that, as a result, cars might collide at the intersection ? The answer to this question seems quite clear—it cannot be said, as a matter of law, that the type of accident that did occur was not reasonably foreseeable.
There are many eases dealing with analogous situations. Thus, where the first actor negligently maintains an obstruction in the public streets and the plaintiff is required to go around the obstruction and is injured by the negligence of a second and subsequent actor, the second act of negligence is reasonably foreseeable and both actors may be held liable.

v.
Central Counties Gas Co.,
Respondent attempts to distinguish some of these cases by urging that most of them involved situations in which the defendant had direct control of the instrumentality causing the injury, and therefore had superior knowledge of its location, condition and propensity. This may be true, but such reasoning does not distinguish the rationale of these cases. Under the allegations of the respective pleadings Tipri’s acts created the specific condition which resulted in the injury. While he did not construct, maintain or repair the lights, his negligent acts did cause them to cease to function. Under the circumstances reasonable minds can differ on the issue of foreseeability. Therefore, Tipri’s liability involved a question of fact and not of law.
Some contention is made that foreseeability in such an action must be pleaded and that the pleadings are defective in this respect.
It is
undoubtedly true that if the' possibility of the intervening act is not obvious from the facts of negli
