Which factor contributes most to vehicle rollovers?

Which factor contributes most to vehicle rollovers?

• A. Improper load securement
• B. Driving slowly on ramps and turns
• C. Defensive driving
• D. All of the above

Answer: (A)

Rollover risk comes from how weight is distributed and how secure the cargo is. When a load isn’t properly secured, it can shift during acceleration, braking, or turning. That shift changes the vehicle’s weight distribution and can raise the effective center of gravity or create uneven axle loads, making the rig more prone to tipping over, especially with tall or heavy loads. Driving slowly or using defensive driving helps reduce risk, but they don’t introduce the instability themselves; securing the load is the direct factor that most increases rollover danger. To prevent rollovers, always use proper restraints, check tension, and ensure loads are evenly distributed and secured before and during travel.
