Don't allow passengers to lay their seat back so they can sleep

When the passenger seat is leaned back, the seat belt is sitting way above the body. In the event of an accident, the passenger can slide around the seat and be thrown against the side of the car or hurled against the seat belt and then back down hard enough to sustain physical injury. People have died this way. Please insist that all passengers sit properly in their upright seats with the seat belts secured. If someone is too tired, consider stopping so everyone can rest.

Additionally, do not allow passsengers to curl up along back seat, or to sleep unsecured in the cargo area of a larger vehicle. In the event of an accident, even a minor one, these passengers are loose missiles in the car. Even a minor accident might kill them.
