When You Need to Report a Car Accident in PA and Other Rules

§ 3747 of the PA motor Vehicle Code requires the driver or owner of a vehicle involved in a PA accident to make report to the Pennsylvania Department of Transportation. Even if the police do not investigate an accident, the driver of a vehicle which is in any manner involved in the PA accident shall, within five days of the PA accident, forward a written report of the PA accident to PennDot.

Unfortunately, in a PA personal injury case, this accident report cannot be used in a trial as evidence of the PA accident.
If you are involved in a Pennsylvania car accident, you have a duty report the PA accident by the quickest means of communication to a local police station if the PA car accident involves: injury to or death of any person or damage to any vehicle involved to the extent that it cannot be driven under its own power.
Pennsylvania law also says that if the driver of any vehicle that collides an unattended vehicle resulting in any damage to the other vehicle or property shall immediately stop the vehicle at the scene of the PA accident or as close thereto as possible and shall then either locate and notify the operator or owner of the damaged vehicle or other property.
If the owner or driver of the other vehicle is unavailable, this information should be attached to the damaged vehicle or other property. You must also promptly notify the nearest police.
