I was parked behind a car in on a street and and to get out I had to back up a little, I looked all ways and made sure there’s no one behind me. So I started backing up but a car on the next lane over made a left turn and sideswiped my bumper hitting his door . The car making the turn crossed into the opposing lane to complete the turn and that’s why there was a crash. Who’s at fualt. In NJ
