2Vehicle rollover: the most likely to be deadly
A rollover accident occurs when a vehicle tips over onto its side or roof.
Rollovers are rare. According to the National Highway Traffic Safety Administration (NHTSA) they only represent 2.1% of car accidents. They however account for 35% of all vehicle crash casualties.
Most rollovers are tripped, meaning an external object (curb, ditch, slope, guard rail, other vehicles, etc.) makes the car tip over. The higher the vehicle and center of mass, the higher risk: SUVs, vans, and trailers are more likely to roll over.
Data shows that 85% of rollover deaths are the result of single-vehicle crashes.
