Which type of collision involves the vehicle overturning?

• A. Head-on
• B. T-bone
• C. Rotational
• D. Rollover

Answer: (D)

The main idea is that a rollover describes a crash that ends with the vehicle tipping onto its side or roof. In a rollover, the forces during impact cause the car to rotate about its vertical axis and lose balance, often more likely in vehicles with a higher center of gravity (like SUVs and pickups) or when sharp steering, sudden swerves, or uneven terrain initiate the flip. Because the defining outcome is the vehicle overturning, this type of collision specifically involves overturning.

Head-on collisions involve a frontal impact between vehicles or an object, not the vehicle tipping over. A T-bone is a broadside side impact at a right angle. A rotational collision describes spinning during impact, which may or may not lead to a rollover, but does not by itself define overturning. So the one that inherently entails overturning is the rollover.
