Typically even if the person driving your car has his or her own insurance your insurance will be the primary payer for damages caused by your vehicle.
Can a person without insurance drive your car. Driving without insurance is illegal in most states. This means your insurance will likely cover another driver in the event of an accident as long as they had your permission to drive your vehicle. If someone borrows your car on a regular basis they should be included as an occasional driver on your insurance policy.
Theres no steadfast rule that says insurance must follow the car or the driver on the policy. How do you get that. There was a time when many fully-comp policies automatically gave you third-party insurance to drive any car but those days have gone.
Theres no law that says you cant purchase a vehicle without a drivers license. The short answer. Nonetheless you need to know that laws in every state forbid a person to.
The car insurance typically follows the car not the driver. So if you lend your car to your best friend your sister or even your second cousin your insurance is most often the insurance that will pay in the event of an accident. If someone borrows your car and crashes it your insurance will cover the losses however your premiums may increase.
Think of it this way. You need to buy insurance from a private insurance company. Depending on the insurer and the situation you may be covered if you give an uninsured driver permission to drive your car and they cause an accident.
Your liability coverage can pay for damages up to the limits of your policy. As long as your friend has a drivers license your permission to use your car is not doing anything illegal is not using the car for something not covered by your policy like business use and does not drive your car on a regular basis they will be covered by your insurance. Your auto insurance covers your car not the person driving it.
