My question involves a traffic accident in the State of: New York
An attendant at a parking lot was waving me forward when the driver of a parked vehicle opened his car door. The right corner of my bumper contacted his door. My bumper sustained a couple of scratches and his door is slightly dented but still opened and closed fine. The other driver took pictures of his car door and I gave him my insurance card. I asked the other driver for his insurance card while he was talking on the phone, but while I was talking to one of the parking lot attendants he left the scene and I don't have any of his information. No police report was filed.
I can take care of the damages to my car myself, but am not sure if I should report the incident to my insurance company or wait to see if he files a claim since I don't have any of his information. I've never been in a situation like this before so didn't really understand all the rules and was a little flustered .
