If you are pulling into traffic, from a being parked, you have interrupted the flow of traffic. That's the tricky part about parallel parking; when to do it and how not to interfere with cars. But there is also a last chance clause; if a car sees you from a good distance away they should make every effort to stop, even if you are blocking their way. If the accident was avoidable, the car striking the car in a parking manuver can also be held liable.
It is your fault.
Backing up--it is your fault.
Yours since the car on the road has the right of way. You actually hit them since they were in the road when you pulled out.
The greater fault lies with the person backing out of the parking space. You may still be partially at fault for not driving with due care.
In general, the driver who is backing is considered to be at fault.
If you strike him - you are at fault. He can be charged with the No Parking violation but YOU are charged with the collision.
Usually their is no fault associated with parking lots. I'm sure your insurance company looks at it as your fault.
