It's not legal to park on a freeway, period. If a vehicle is broken down or otherwise abandoned on the side of the freeway (and most other roadways, as well), once it is discovered by the police, a sticker will be placed on the windshield, notifying the driver they have a certain period of time (usually 24 or 48 hours) to have that vehicle removed, or else it will be towed and impounded.
In my area (western Canada) the first police to see it write a large time code on the rear window. -After that you have 24 hours to remove it or they will tow.
As little as 4 hours.
In California, 4 hours.
Four hours
In most locations in the US, police can cite the owner of the parked car for illegal parking and obstruction, and in some cases it will be towed away. You should know your liability before having the vehicle removed on your own.
have you checked the batterys even if there not installed in the vehicle the can still drain down
driver of parked vehicle
If the other vehicle was parked, there was no other driver to have license, insurance or registration. The driver who hit the parked vehicle is at fault and is liable for all damages to the parked vehicle.
The driver of the backing vehicle. The fact that the car was parked illegally is irrelevant. The onus is always on the driver of a moving vehicle to ensure the way is clear before backing up.
As long as the parked vehicle is parked properly and not illegally parked in any manner, then the vehicle that rear-ended the parked car is at fault. Now if the parked car is sitting illegally (such as double parked or parked in a no parking zone, etc.) then the parked car is at fault or even both the parked car AND the car that hits it are BOTH at fault.
Yes. Being illegally parked does not affect fault. If you strike a parked vehicle, it is ALWAYS your fault because you have a duty to ensure the way was clear before moving.
Aeroplanes
The driver that hit the parked vehicle would be at fault.
