Dooring accidents occur when a car driver opens their car door in the direct path of a moving cyclist. Dooring incidents happen because of the negligence of the driver and their failure to inspect their surroundings for the safe opening of the door. If the rider was approaching with speed, they could suffer serious injuries because of this kind of action. You can sue the person who causes your injuries from a dooring incident. Contact a lawyer if you've been struck by a car door.
