今天我倒车时,撞到一辆慢驾驶车。把对方后门擦了一些痕记。since i have no driver's licence( only learning licence, no insurance) so i said i want to pay him money. And we go to garge to ask the price for reparing. Because it is lunch time. so we went to two place and didn't find workers. The driver asked me how much i would like to pay. i said i have no idea. he said how about $250. I agree. then i paid him$250. he said everything is over. But i worry he knows my car plate number. can he call police? ( he only knows my plate number) or maybe he can do something bad to me? in his car there is woman, she said the driver is very nice person. but i don't know if i shohld trust him. hope somebody who has same experience could give me some advices. today is really bad day for me. I highly appreciate your help!
