i was told its because they are for when you are parked only, and if you drive with them on someone could mistake that you're parked and hit you.
depends on whether or not the car is parked well. if the car is parked properly, in the right spot then it should be the car that hit it that is at fault.
Get the license number and insurance info from that person
How do you hit someone while parallel parking???
Whom ever hit it. If it was in park then who hit it is responsible. Depending on the circumstances, your employer should be.
I think it would have to be the person who hit your car because they caused your car to crash into the other car.
Assuming the parking lot was open, and the car had every right to be parked there. The owner of the snowplow, and possibly the operator of it would be liable for damages to the parked car.
From your question I am perceiving that you parked straight and someone came and parked beside you but the rear of their car is blocking the rear of your car. You would be at fault because you should have realized that you wouldn't have been able to back out. In that case you should have contacted the local police (don't call 911) to have them do something with the car if you are not able to find the owner of the vehicle.
Either the parking brake / transmission gave out or sombody else hit it for you.
Several things can happen. Allowing you parked legally other than insurance: the person who hit your parked car is responsible to pay damage. If you were parked on private property the lack of insurance means nothing. If you were parked on a public road or public parking lot you could be on the hook for a ticket for uninsured vehicle, but the other guy should pay anyway. Don't admit to driving with out insurance!
YES TO MAKE A POLICE REPORT DEPENDING ON WHERE YOU WERE PARKED THEY MAY HAVE A VIDEO IF IT WAS IN A PARKING LOT IF IT WASNT THEN I DONT KNOW
It depends if the illegally parked car is a danger or interuption to the normal flow of traffic. For instance if someone is parked in a handicap spot illegally, and you hit them, obviously it is your fault. You need to be able to prove that due to the other persons actions of illegally parking, it inevitably led to you hitting their vehicle. Just remember, you are the one moving, and you are the one who hit the "non-moving" object.
