the lady who backed into you, clearly she wasnt paying attention and backed into your car
Whomever backed into it is at fault.
Both of you. Neither driver was watching where they were backing. The ultimate fault will be determined based on the police report and an investigation.
Who knows question not clear enough.
you are at fault
Car A is at fault.
You Dummy!!
It depends on local laws, but in most places the person who backed into the car is at fault since they had the last clear chance to prevent the collision.
The fault of the one who backed in to you, unless you made a very unpredictable, unnecessary stop.
It is your fault.
If you can prove it, the other driver is at fault. It is stated in the NRS 484.449 (limitation on backing), but most likely the other driver's insurance will tell you that both of are at fault and claim 50/50 responsibility.
If they backed into you, it's their fault. Failure to yield.
the guy who backed offcourse
