Not so much an accident, more a mechanical failure but still pretty funny, although not at the time.
Back from Uni, holiday job van driving, weekend i thought i'd "borrow" my works P100 to go to Hull from Wokingham to get pick up my stuff. So set off nice and early to get here and back in the day. Been sat at 85-95 all morning, just 10 minutes from Hull so about 3 and a half hours in to the trip, at 85 in the fast lane overtaking, still going so empty van no weight in the back, the gearbox seized, rwd so teh back wheels locked instantly, the gearstick moved about a foot, popping the dash open into my face and onto my lap, the back started jumping around side to side, lots of wheel twirling and screaming like a girl, black smoke everywhere, strong odours from my arse, and i finally, somehow, bought it to the hard shoulder sort of pointing the right way with big stripes on the road as far as i could see, still shaking and weeping fluids, me and the van, phoned the RAC who turned up an hour later, then left again to get a flat bed, another hour or so i got winched onto said truck and taken to Leicester and unloaded, then waited for another truck who took me back home. Gutted, i hadn't got my stuff anf had to explain to the boss why their van was blown up outside hull on a saturday!!
Not to worry got a brand new transit out of it which was nice
