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.
When this happens, your Insurance company pays for damages. If the accident is your fault, your insurance rates can go up.
It would be no difference than if the people involved in the accident had different insurance companies. The coverages are the same so there would be no difference.
no insurance + jail
I was arrested for having expired registration in Massachusetts. Seriously.
Yes it does. The cancellation of an insurance policy is not retroactive.
If stopped or in an accident they will be arrested and the vehicle will be impounded. This is the only answer I can give you.
You will have to pay fines if your car gets impounded for no insurance, registration, and inspection in PA. You will have to registration before the car is released.
The same thing that happens if you did not have an Sr22. The at fault parties insurance generally pays for the accident.
You get arrested
If both drivers have no insurance and do not file a police report, each driver is responsible for repairing the damage to his/her own vehicle.
