Yes - in UK law you would be considered At Fault for such an accident. Please see the link below to see how to determine fault generally in a road traffic accident.
It depends on whether or not the car is stationary at the time of the accident. If your car is stationary and they stumble into it, then they are at fault. However, if your car is moving when they are hit then you're at fault.
The car in motion is ALWAYS at fault when it hits a stationary vehicle.
If he was truly stationary and you hit him, you are probably at fault. If he was illegally going through the turn, he might be at fault.
The car that rolled into the parked car is at fault.
Yours. If it was stationary and you hit it then it was your fault.
You are. You didn't park your vehicle properly. The fact that the other vehicle was parked illegally doesn't give you permission to crash into it.
Car A is at fault.
Car 1 would be at fault as it was the initiator of the acident.
Yes. You are always at fault when you hit a stationary object.
Assuming you're talking about a parking lot situation, generally there is no way to establish fault in such an incident. Unless you're a fan of the old "Brady Bunch" TV series. A 50/50 fault, where each driver pays their OWN repair costs.
It would be the owner of the skateboard's fault. Especially if the skateboard does any damage to that car.
it stays the same
