If you caused the accident, most policies don’t provide coverage for a rental vehicle unless you buy this additional coverage. If another party was responsible for the accident, the insurance company for the person who caused the wreck is required to provide you with a rental car. If the other driver is at fault, we will demand that the insurance company for the person who caused the accident provide you with a rental car for the time needed to repair your vehicle. Sometimes, you must pay the rental car bill first, with reimbursement coming from the insurance company later.
