To be at fault for an accident means that your negligence contributed to the accident — i.e., your negligence was a factual cause of the accident. It is perfectly possible to violate the vehicle code without being at fault for an accident. However, if you violate a law or vehicle code provision where that violation caused or contributed to your accident, and that statute was intended to prevent such types of accidents, then there is a presumption of fault. Frequently, there are multiple causes of an accident. It is very possible for both you and the driver to be at fault.
