Yes, this presumption is called negligence per se. Negligence per se requires that the driver violated a statute, that you suffered an injury, and that the statute the driver violated was intended to prevent such injuries. Here is an example of negligence per se: You are riding through an intersection legally on a green light when a negligent driver strikes you running a red light, in violation of California Vehicle Code section 21453(a). Red light laws exist to control traffic so as to prevent vehicles from colliding into one another at intersections. Because the driver caused such a collision as a result of violating the red light law, they are presumptively negligent by law.
