Parking regulations are typically designed to facilitate the free flow of traffic or for the safety of motorists lawfully traveling on the road. If you struck an illegally parked car you may have a viable injury claim. A viable injury claim generally requires a finding that the car was parked or stopped in a location that endangered approaching motorists. An illegally parked car on a highway, in a travel lane, near a sharp bend in the roadway or a hill is a serious danger. Drivers that leave their cars in such dangerous locations are responsible for the injuries they cause.
