How to handle running off the pavement

The National Highway Traffic Safety Administration recently conducted a study to find out what the effects are. According to their tests, a 15-passenger van that is lightly loaded has a rollover risk that's comparable to a light truck. But a van with ten or more passengers is three times more likely to roll over than a van with fewer passengers. While many actual rollover accidents had other contributing factors, such as a driver who used excessive speed or steered off the road, nonetheless, NHTSA's tests clearly show that the margin of error when driving a van is much narrower than for a car.

If I have to use a 15-passenger van, how can I be safe?

Driver awareness is always the most important safety factor. Don’t drive while fatigued, and if possible avoid driving at night when sight is limited. Never speed; this is even more important in a van than in a smaller car
