Preventing Auto Rollover

A vehicle rollover is one of the most devastating types of road accidents, accounting for a higher rate of fatalities than any other single kind of accident.

Transport Canada recently conducted an investigation into the frequency and cause of light vehicle rollovers in Canada. The report shows that there are approximately 25,000 collisions involving a light-duty vehicle rollover per year in Canada and that these collisions result in the death of approximately 500 persons and injuries to another 15,000 to 17,000 persons.

Most prone to rollover are tall and large vehicles such as SUVs, minivans, light trucks and 4-wheel-drive pickups, because they have a high center of gravity and a narrow track relative to the height. These vehicles can roll over when they hit a pavement, drive through soft dirt, make a sharp turn at speed, or collide with another car.

Although it happens much less often, other types of vehicles can also roll over. The cause is usually due to the vehicle being top heavy (such as from carrying equipment on a roof rack) or swerving suddenly at speed.

Tips for preventing rollovers and minimizing damage:

• If you drive a rollover-prone vehicle (see above), choose routes that allow you to drive on smooth, hard road surfaces in good repair.
• Drive sober: Never, ever drive under the influence of drugs or alcohol.
• Ensure the driver and all passengers wear their seat belts at all times. 78% of the people who die in vehicle rollover crashes were not using a seat belt.
• Drive defensively: Many rollovers occur as a result of panic moves to avoid a collision. Be constantly aware of traffic conditions and drive as defensively as possible.
• Do not overload a roof rack, making the vehicle top heavy.
• When shopping for a vehicle, compare safety features and ratings and choose the safest vehicle you can afford.
