What factor increases the risk of vehicle rollover?

Answer: B — Speeding through turns or evasive maneuvers

Speeding through turns or evasive maneuvers significantly increases the risk of vehicle rollover due to the dynamics of vehicle stability. When a vehicle is driven at high speeds while turning or when sudden maneuvers are executed, the center of gravity shifts dramatically. As the speed increases, the lateral forces acting on the vehicle become more pronounced. This can cause the vehicle to lose its balance, particularly in taller vehicles such as SUVs or trucks, which have a higher center of gravity compared to sedans. In sharp turns or during quick evasive actions, the force of gravity combined with outward inertia can lead to a dangerous situation where the vehicle tips over. Proper vehicle dynamics suggest that maintaining a lower center of gravity and making gradual turns can help mitigate this risk. Therefore, understanding how speed affects vehicle handling is crucial in preventing rollovers.
