I was angle parked at an auctioneers while collecting items bought. A truck was parallel parked slightly further up the driveway behind me. I carefully backed out as I had to back around the rear of the truck and it was stationery at the time. It started moving when I was completing my turn and I saw it looming up so stopped but he continued and after scraping the rear driver passenger door severely, the truck ripped off the rear bumper. The driver gave me his name and address and phone number but said it was my fault and he had borrowed the truck so didn't know the insurance details. Then he drove off. When I phoned him to get the insurance details he put the phone down. Fortunately I am insured and have had a quote for $3,300 to repair the damage from the car accident but I have to pay $800 excess which I cannot really afford at the moment. Is there any way I can demand the driver or the insurance company of the truck to pay this under Traffic Law? My car insurance company says in this sort of claim due to reversing the respective vehicle owners have to pay for their own damage but the truck wasn't damaged at all.
