Facts are not clear: "left hand turn" from where to where? In general, entering a public way from private property has to yield to everyone lawfully upon the public way. However, every person (including turning left) has obligation to observe other drivers and avoid collision if possible (the "last clear chance" doctrine). Cannot determine potential "fault" from slim facts you have provided.
It is the person who is blocking the private driveway's fault because they should have known not to park in front of a private driveway in the first place. However, if the private driveway is not marked with a sign of some sort to let people know that it is private, it may be the driveway owner's fault.
Don't force the wording of the event and I believe the answer to: "...when you back into someone....", is evident. Add to it, "...when exiting a private driveway...", where one is always required to yield to the traffic on the public street.
Pedestrians have the right of way. Unless you can prove he/she was grosely negligent or did it on purpose then you are at fault. If you are backing down on your private driveway and a neighbor who walks behind your car on your private driveway is hit and falls down who is at fault? The neighbor pedestrian has been drinking, unstable on his feet was standing in his driveway at his car then suddenly is behind my vehicle.
It is the persons fault for entering your private driveway.Another View: If the collision occurred on private property, the insurance companies of both cars will be involved. As a general rule, the driver of the backing vehicle bears the responsbibility for making sure that he can safely proceed in reverse.
Both states and municipalities establish traffic laws. In most instances person exiting a driveway whether private or public will be held accountable for an accident. The premise being, that driver is entering into the "traffic flow" and is required to use reasonable caution and take no action until the right-of-way is safely clear.
BOTH drivers are at fault for backing without caution. If the accident occurred in a driveway on private property, no ticket was probably issued. Turn it over to your insurance companies.
The person pulling out of the driveway is at fault.
any vehicle leaving private property and entering a public road ,is at fault. all vehicles leaving private property MUST yield to vehicles on a public road
If you were fully in the lane, and he is backing from private property onto public property more than likely he will bare the majority of fault/liablilty.
doesn't matter if an accident was on private property. get a police report immediately. this will be used to determine fault, if any.
The rear car would be at fault for not making a safe pass.
The person backing out of the driveway.
