Pam has the right of way in most cases.
You are at fault.
the car backing out.
Your mum, Steve.
Most defintley his fault, you were backing out, he should have saw you first.
From the explanation given in the discussion area - it would unfortunately appear as if both drivers were at fault. The backing driver for not being aware of his surroundings, and the other driver for failing to yield to the backing car when he saw that the backing car was already in motion.
A vehicle traveling in a parking lot has established use of the lane and the right of way. A vehicle in a parking space and backing into the lane must yield to oncoming traffic. Therefore, if a vehicle is backing out of a parking space and pulls into the path of an oncoming vehicle that has already established the lane, the vehicle backing would be at fault for the accident. However, if the vehicle which established use of the lane had an opportunity to avoid hitting the vehicle backing out of the space and failed to do so, there could be comparative negligence on both vehicles or on the one who had the opportunity to avoid the accident.
The person driving through. If you're backing out then you do not have the right of way.
The person backing out due to the other car having the right-of-way.
Backing up or entering a lane of traffic is always determined to be the cause of an accident. Drivers in those situations are required to yield to approaching traffic.
You are. Improper backing.
The car going backwards.
Is it possible that you are both at fault? The person backing out is at fault. He was stopped and should have been looking before backing out. However, if the parking lot is designed so that you can only go one way, then you may be at fault. The insurance companies will look at the police report and fight it out.
