Will my car insurance cover a rental car if i sell my car?

Insurance covers the car identified in the insurance policy. You could ask if they could transfer your insurance policy to the rental car.

it depends... is that the only car on the policy? if so, then no once u have no more vehicles.. you can no longer have car insurance. you no longer have an insurable interest in the vehicle. But if you have car insurance on a vehicle and you have the right coverage (OPCF 27) then your auto insurance will cover the insurance portion of your rental, assuming u have collision and comprehensive on that policy.
