Unfortunately, your boyfriend hasn't got a leg to stand on *guffaw*. While the woman may well be exagerrating, she's obviously trying to milk someone for everything she can. I'm pretty sure that in the eyes of the law, your boyfriend was in the wrong on all accounts:
- The woman may have been stopping or slowing down for anything/anyone and so your boyfriend wasn't exercising due care and attention to the oncoming traffic;
- He swore (forgiveable and understandable I know, but likely to be frowned upon); and
- He didn't have insurance (that's not forgiveable at all).
The woman may ask you for a payment for the damage - I suggest you go for this. Otherwise, she'll take your boyfriend straight to court; he would lose, have some kind of punishment for not having insurance, which is very illegal,
and have to pay further fees, like court costs.
