Well if you were backing in and hit someone then it is your fault. But if they hit you, then it is their fault.
Backing up--it is your fault.
Any time the driver who is backing is at fault, in all 50 states.
both of you for not looking back
The person backing out. If you were in the lane/road behind them they needed to use caution when backing out.
If you are driving the backing car, no matter WHERE the other cas is located, YOU are the one at fault if you collide with it.
Whoever the police report charges with the accident.
If the person backing out of the space had not seen a pedestrian walking the "wrong way" it would be the fault of the driver of the car backing out....... So it is the fault of the person backing out. They did not look to make sure it was safe to do so.
The car that is in motion is ALWAYS at fault.
Depends on the jurisdiction, but typically, two vehicles backing up is a 50/50.
If you were both backing out at the same time, then it will be considered joint fault, sometimes called contributory negligence. That means both drivers failed to notice the other driver.
The greater fault lies with the person backing out of the parking space. You may still be partially at fault for not driving with due care.
If they backed into you, it's their fault. Failure to yield.
