If someone hit you and they were in a rental car does their insurance cover you or the rental company's insurancethey didnt take additional ins through rental comp?

if the renter has insurance on another vehicle and are using/renting a vehicle, (few exclusions on this but doubt they would apply)......in place of their vehicle.......the insurance on their vehicle (that is in the shop or whatever).....transfers to this rental car, as: non-owned auto, temporary substitue vehicle etc.........so whatever or whomever their vehicle is insured with will cover you (assuming they are at fault of course).......rental car companys will not rent to someone without a copy of their insurance (liability)........a person can purchase a 'damage waiver'' from the rental car company, but that only covers the rental car its self........if something very out of the ordinary occured and vehicle was rented to an uninsured person or an exclusion in their policy removes them some how......then the rental car company policy would come into play........i have never seen a rental car companys insurance pay a claim (always the drivers)........ unless it was an employee driving the vehicle..........so find out who the company is that the driver has........ Most states require that all vehicles be insured against damages that are caused BY THAT VEHICLE. The auto rental companies are required to carry liability insurance on any vehicle they rent. Don't let anyone get away without paying for the damages to your vehicle.
