My teen son ever so slightly bumped another cars rear at the stop light. Both he and the driver of other car got out and she was very angry insisting on his insurance information even though there was no visible damage. She had a black vehicle which was very dirty from the winter roads. She said she wanted to make sure there were no scratches after she washes it. We asked her to contact us instead of going through her insurance because we'd rather not have to pay a surcharge for something very very minor. She texted my son today telling him to have me call her. I am afraid she is going to make up all this damage just to take advantage of us. We took pics of her bumper and you clearly see no visible damage to her car. I just want to know how we can protect ourselves in this type of situation. I'd hate to give her cash then have her turn around and call her insurance trying to collect more money. There is no damage to our vehicle either. I haven't been able to reach her yet she doesn't answer her phone the times I have tried to call.
