The most basic question to determine who is responsible for an accident is “Who made a mistake or was negligent?”. From there, facts about the accident are examined to determine who’s at fault. If your vehicle was rear-ended, it almost always is the fault of the driver behind you since one of the fundamental driving rules is to leave enough space in front of you so you’ll be able to stop when the car in front of you suddenly hits the break.
