Bicycles are recognized as "vehicles" in every state, according to the state's traffic or vehicle code. This means bicyclists are required to follow the same rules as all other automobiles on the road. So, if there is a collision between a car and bicyclist, that means the fault is assigned by "the general principals of negligence."
For example, if a cyclist fails to stop at a stop sign, and is struck by a car, he will be determined as negligent. Therefore, he cannot receive compensation for his losses.
