Your first call should be 911. This will alert the police and create an official record of your accident. The police dispatcher will then notify the Philadelphia Police Department or the Pennsylvania State Police depending on the location of your collision. If you or anyone else appears seriously injured, ask the dispatcher to send an ambulance. That way, whoever’s injured can be examined by an emergency room doctor at Temple University Hospital or another nearby Philadelphia medical facility if necessary. If you’re healthy enough, gather evidence at your crash site as well. Take pictures. Talk to witnesses. Get their contact information. And exchange information with the other driver. As soon as possible, call a lawyer as well. An experienced Philadelphia car accident attorney can help you every step of the way.
