well you notify police and let them deal with it
The best thing to do in this situation would to be to contact the police and let them know what happened. That way they could do a police report and contact the other driver and keep you from getting in trouble for leaving the scene of an accident.
Depends. If you have a licence for it or not. But, you could be fined for the exposure of it in possibly a dangerous place.
It would be the car who had parked illegally because he was not parked in a legal spot.
i was told its because they are for when you are parked only, and if you drive with them on someone could mistake that you're parked and hit you.
Strange as it may seem. I know people who have parked up their car then forgotten where they parked it, I have even driven them round looking for it. In multi storey car parks the modern remote keys help you flash the car lights in this situation.
because your car is parked below
Yes. Being illegally parked does not affect fault. If you strike a parked vehicle, it is ALWAYS your fault because you have a duty to ensure the way was clear before moving.
because it's too small to fit in the alcove
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.
As long as the parked vehicle is parked properly and not illegally parked in any manner, then the vehicle that rear-ended the parked car is at fault. Now if the parked car is sitting illegally (such as double parked or parked in a no parking zone, etc.) then the parked car is at fault or even both the parked car AND the car that hits it are BOTH at fault.
The one backing out, because you should realize someone is opening a door.
it is not possible because it is not moving
