He's family, be thankful he wasn't killed. On the other hand your truck was by admission old and obviously not worth very much if you dropped coverage. Go find another that needs work or a clutch or something if you're a DIY type guy; sit down with him and his mom and just say that he will be expected to help yank an engine and change a clutch or whatever it needs within reason and he won't be payed; but he'll likely learn something in the process and be more responsible with other people's stuff after he scrapes his knuckles up on a few rusty bolts. Staying mad won't do much good...try to turn it into something positive. Once you feel he has worked it off don't bring it up ever again.
