Your parked car was struck by a moving vehicle and your collision insurance paid for your car damage. Can you sue the driver of the other vehicle for other expenses such as car rental?

More than likely you signed away your subrogation rights to your insurance company so that they can recoup the amount paid to fix your vehicle. They will get his auto policy to reimburse them for the payments they made to you. When and if they acquire All the Money Owed, they will refund your deductible that you paid if any.
