just call his insurance, nothing will be against you. just tell them he hit you said he was sorry and gave his information. he knew he was at fault that's why he didn't take your info.
my insurance guy told me one thing you try to never do is give someone your insurance info cause that admits you're at fault in some way
I T-***** a nyc cop car a few years ago and I was ******** myself cause I thought that's it I'm done ill never drive again lol. but lucky for me my phone was recording and caught him admitting he didn't see me and he was in a rush. because we both exchanged information obviously the city was finding me at fault and my insurance said if you know you're not at fault don't give your info. the city found me 80% at fault and was only willing to pay 20% of the damage. he told my insurance that he thought I had a stop sign so when I was approaching the intersection he thought I was gonna stop so he went. 1my insurance found him 100% at fault and paid the other 80% to fix my car and didn't use it as a mark against my driving record. they ended up getting their money back from the city after everything
