Whomever backed into it is at fault.
The individual who had custody over the unattended, parked vehicle would be at fault. Clearly, the vehicle was not adequately parked (or not up to safety standards) if it rolled down a hill and damaged persons/property.
You do.
You Dummy!!
definitely not, perhaps if you parked in a no parking zone.
nothing
you are. you should have been paying attention. it doesn't matter if the other car was attended or not. you are responsible for you and your vehicle.
I hope you got a police report. In any case, whether or not you were parked legally is not relevant. A driver is responsible for damages caused when hitting any stationary object... like a parked car. Just offer to take her to small claims court, or contact a lawyer. Most lawyers would just consider that one fun.
It would be the car who had parked illegally because he was not parked in a legal spot.
Of course it is your fault. The fact that the car was illegally parked is of no consequence. You didn't look where you were backing or you would not have hit the parked car. Would you have hit this car if you had been looking? Perhaps the illegally parked car is a Mini Cooper, parked illegally 1 foot behind a Hummer and therefore not visable when the driver looks before backing up...
i'd have to say the person who left the car running. if they didnt leave it running they could have prevented the thief from smashing it into your car.
Generally speaking, the driver in motion is considered to be at fault when a parked car is hit, even if the car was parked illegally. The exception to this would be if the car was parked in a dangerous, hard-to-see location and the driver in motion could not have reasonably avoided hitting it. For example, if a car is parked on a sharp curve in the travel lane of a narrow road, and the driver of a car driving around the curve at the speed limit would not be able to see the parked car until too close to it to avoid a collision, then the driver might not be liable for damage to the parked car, and indeed the driver who parked the car might be liable for damage to the car that hit it.
