I had a problem last week in an off-street car park with the car of one friend (I did borrow it for the weekend and he does not have a car insurance). It was raining, and while opening the back door, one of the passengers in my car hit the car that was parked beside my car. Both cars were turned off. The owner of the other car went out and asked me to provide my name (which I did) and called his car insurance. Damage is almost invisible (just a little mark on his door). I just receive a letter from RACQ insurance considering it as an accident. Question is, can I use my passenger public liability insurance since both cars were not running? Thanks for your help.
