Hello. I got rear-ended while exiting the freeway in Los Angeles, CA by a driver who said he was hit from behind by another car that fled the scene. No police report was taken. I had a rental car from Budget and I took out Rental Liability Insurance (not the Loss Damage Waiver, though). The other driver's insurance, State Farm of California, refused to pay claiming their driver was negligence-free since he was hit from behind. I only have damage on my rear-end. The other car is damaged on both sides, though there is no proof the other car's rear-end damage happened the same day. Is the rental company right to make me pay?
