The car to the rear, unless the car struck was backing. Depends on the situation.
If with "one impact from the last car" you mean that the rear car hit the middle car and then the middle car, as a result, hit the front car, the rear car's insurance would be responsible for all damages. If the middle car first hit the front car and then the rear car hit the middle care, the rear car's insurance would only be responsible for the damages to the middle car. i.e. where was the first impact?
A car with the engine in the rear should have rear/all wheel drive. A car with the engine in the front should have front/all wheel drive.
If you rear end a stopped vehicle, which is pushed into another stopped vehicle and then that into another, you would be responsible for all of the vehicles.
The driver who rear ended you is at fault.
the car that hit you in the rear is at fault. think about it this way. What did you do wrong if you were stopped
you need to file a claim against their insurance company- anyone who hits you from behind was not alert enough to stop in time- unless this is a fraud most people who are hit from behind should not be at fault
walk around the rear of the car
From your question I am perceiving that you parked straight and someone came and parked beside you but the rear of their car is blocking the rear of your car. You would be at fault because you should have realized that you wouldn't have been able to back out. In that case you should have contacted the local police (don't call 911) to have them do something with the car if you are not able to find the owner of the vehicle.
Usually it's the company of the car that hit the parked car regardless of location.
If the car that rearended you without being hit by the third car first then the car in the middle is at fault for your damage and the third car is at fault for the damage to the rear end of the middle car. The first car is not at fault for the quick stop.
When a vehicle is in a car accident there can be a secondary collision. For example, if car ÒbÓ was rear ended that is the first collision but when that car hit the car in front of them that is the secondary collision.
