Ds' cars collided at an intersection. P was in his car, waiting at a stop sign. P, the ever good Samaritan, put out flares and directed traffic. P noticed his car was impeding traffic. He asked a young man, White, to move his car out of the way. White was too young to be licensed as a vehicle operator. He got in the car, lurched forward, struck another vehicle, veered across the street and struck P. This occurred about 15 minutes after the initial collision. P sued Ds and contends that the jury should decide if D is liable for P's injuries from her initial negligence in causing the first collision.
