Is it legal to have people sitting in the back on a camper without a seatbelt if there isn't one avaliabe? I read that somewhere but I dont know if it's still the case. so what's the legality of having passengers in the back, do they need seatbelts, and does this differ a lot througout europe? I've been hitch hiking for the best part of 5 years, and I really wanna pick up hitch hikers when I'm travelling Europe, but I'd like to do so legally.
