Rollover crashes most commonly result from which factor?

Rollover crashes most commonly result from which factor?

• A. Driver fatigue
• B. High speeds
• C. Poor weather
• D. Equipment failure

Answer: (B)

Rollovers are driven by the forces that push a vehicle to tip when it changes direction or encounters a loss of control. As speed increases, the centrifugal force felt during a turn or sudden maneuver grows, making it easier for a vehicle—especially one with a high center of gravity—to tilt onto its side. SUVs and pickups are more susceptible because their weight is higher above the wheels, reducing stability in corners or on uneven surfaces. So, the factor that most strongly raises the odds of a rollover is high speed, which magnifies the lateral forces that can overwhelm a vehicle’s stability. While fatigue, poor weather, or equipment failure can contribute to crashes in general, they don’t explain why rollovers occur as frequently as speed does.
