Who pays for the rental car while my car is in the body shop?
When the claim is against the other driver's company , the other driver's company should pay your rental car cost for a reasonable length of repair time. If the car is totaled, many companies pay for your rental as a courtesy, but they are not required to do so — your right to a rental ends once a settlement has been offered.
When it's a claim against your own policy , your company will pay if you paid a premium to include rental reimbursement coverage in your policy. Most policies have a dollar limit for rental payments; your rental car rights are spelled out in your policy.
