Generally, who ever is in reverse should yield the right of way.
But if I was the claims adjuster for the insurance company with what you say
(trying to sneak behind you) I would find him partially at fault.
Although if he didn't see you were backing or you had no turn signal on,
you would be the one At Fault.
both of you for not looking back
The person backing out. If you were in the lane/road behind them they needed to use caution when backing out.
Backing up--it is your fault.
Depends on the jurisdiction, but typically, two vehicles backing up is a 50/50.
Any driver that is the backing vehicle has a greater and duty and care to maintain proper lookout at all times. The driver that was traveling on the throughfare has control of the lane of travel and the backing vehicle must yield to them. Infortunately, you would the proximate cause of the accident for improper backing.
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.
I'm confused by the question. You were both backing? And back into each other? If that is correct more than likely you will each be 50% at fault. If you can provide more information (ie, where on each vehicle exactly is the damage, who was farther out etc), then perhaps I can be of more assistance.
Clearly, if you hit a stopped vehicle with yours then you are at fault, regardless of whether you were going forward or backward. Similarly, anyone backing up has an obligation to use the utmost care.Here is a fact you should know . Any accident in a parking lot is not covered by any insurance , only wrecks on public roads . Insurers do cover accidents that occur in private parking lots. The police however will not respond nor make a report unless there are injuries. The person who was backing up will most likely be the "at fault" driver
The car that is in motion is ALWAYS at fault.
check behind the car before getting in
Hard to say. Possibly equal fault by both parties but most likely the person backing out.
Look behind you
