What is the name of your state? Massachusetts. The other person was citated at the scene of the accident for running a stop sign, and there was a witness who saw the accident. Two months later, I finally get my car back from repairs, I had to pay out $760.00 between rental and bettement . I submitted the receipts for reimbursment of full $760.00 because the other person was citated for causing the accident. I now get a letter from the other insured which states they are only paying out 80% towards the rental, because they feel that 20% of the accident was excessive speeding on my part and 0% towards the bettement, because it is my responsiblity. I did not speed, nor could I have, due to the condition of the traffic. I don't feel i should have to pay any amount towards this accident, not even the bettement. I already had to accept the car now having refurbished on it from the repairs. My car is only 1 yr and 2 months old with 21,000 miles at the time the accident occured. Purchased brand new. What steps can i take to get 100% reimburstment from the insurance?
