Most insurance companies will instruct you to call them first when you have an accident, unless there are injuries. You should call the police to get an accident report.
Most likely the the vehicle doing the backing up would be at fault.
Liability coverage extends from the vehicle that is pulling a trailer, boat, or camper. This means if you are backing up in a parking area and the camper hits another vehicle the liability coverage will cover the damage to the other vehicle. Even if you are going down the road and the trailer comes loose the liability is still attached to the trailer and damage it does to another persons property is covered by liability from the vehicle that it was attached to. The kicker is that damage to the trailer itself is not covered by the vehicle pulling it. You would have to have a policy on the trailer itself for physical damage coverage to cover damage to the trailer.
Impossible to answer - nowhere near enough information is disclosed.
In dealing with a towed trailer, the liability coverage will extend from the vehicle towing to the trailer being towed but the physical damage coverage does not extend. This means that if you are backing up at a fuel station and the trailer backs into another vehicle then the liability will cover the damage done to the other car that is damaged by the trailer. Any damage done to the trailer itself will not be covered.
According to the author backing up is always considered dangerous?
Yes, unnecessary backing is frowned upon.
torque converter can cause this. you will have bucking and stalling. another thing it can be ( I know this to be true as it happened to me) is the cat converter.
Driving schools that will teach drivers how long the blind spot on the ground is in back of a vehicle , and enforce checking around the vehicle while backing, as well as tell kids around the vehicle to keep out of the way while backing up.
stand up for them
EVERYTHING and everyone who might be behind you.
no
Assuming that the car hit was stopped when the other car was backing up, the one backing will be at fault. If there is no damage, or if it is below a certain threshold it may not even count as a collision.
