Typically the person who hit you pays. If they don't have insurance, your no fault insurance will pay for it.
If you are hit from behind it is usually always the guy that hit you that is at fault unless you were in reverse backing up
The car that hit you from behind.
It is their fault.
Unfortunatey, if you hit a car from behind, it is your fault. Period. Your insurance will pay for damages and the other person's injuries, if any. Hopefully, nobody was seriously injured, but you can expect your insurance to go up!
you are at fault
If they wern't going backwards when you hit them you are at fault.
The car behind you
the driver behind is not at fault as the in front should be liable as he was negligent
is fault of car behind the second car not yours
Hard to say. Possibly equal fault by both parties but most likely the person backing out.
If you hit someone from behind it is automatically your fault.
