Safety Tip of the Day: Prevent Rollover Crashes

Rollovers are complex crash incidents and are particularly violent in nature. Rollovers, more so than other types of crashes, reflect the interaction of the driver, road, vehicle, and environmental factors. So while vehicle type does play a significant role, other factors such as driver behavior and road and environmental conditions can also cause a vehicle to roll over.

VEHICLE TYPE

All types of vehicles can rollover. However, taller, narrower vehicles such as SUVs, pickups, and vans have higher centers of gravity, and thus are more susceptible to rollover if involved in a single-vehicle crash.

SPEED

Fatal rollover crashes are speed-related more often than fatal non-rollover crashes. Some 40% of fatal rollover crashes involved excessive speeding . Additionally, nearly ¾ of fatal rollovers took place where the posted speed limit was 55 miles per hour or higher.

ALCOHOL

Nearly half of all fatal rollover crashes involve alcohol . Impairment can result from any blood alcohol concentration (BAC) above .00 . Even a small amount of alcohol will negatively affect your judgment, muscular coordination, and vision, making you more likely to lose control of your vehicle.

LOCATION

Rural roads tend to be undivided and without barriers. They are thus more likely to be the scene of a fatal rollover. Almost ¾ of fatal rollovers occur in rural areas where the posted speed limit is typically 55 miles per hour or higher.

ROUTINE DRIVING

NHTSA data also suggest that over 90% of the vehicles in fatal, single-vehicle rollover crashes were involved in routine driving maneuvers (going straight or negotiating a curve) at the time of the crash. This further suggests that driver behavior (distraction, inattentiveness, speeding, and impaired driving) plays a significant role in rollover crashes.

SINGLE-VEHICLE CRASHES

NHTSA data show that nearly 85% of all rollover-related fatalities are the result of single-vehicle crashes. This means that the majority of rollover crashes and fatalities do not involve any other vehicle besides the one that rolled over, further suggesting that driver behavior plays a significant role in rollover crashes.
