Always call the police immediately after a pedestrian accident. Since the victim is often severely injured, a companion or bystander may have to make the call. The police will investigate, as leaving the scene of an accident is either a misdemeanor or a felony, depending on whether anyone was injured. A personal injury lawyer can also investigate the situation and attempt to identify the vehicle that hit you. This is done via an available surveillance video, which may reveal the license plate number. It is then possible to pursue a claim against the driver.
