Why are SUVs likely to roll in the scenario of an accident?

SUVs are more likely to roll in the scenario of an accident primarily due to their high ground clearance. This characteristic raises the center of gravity compared to vehicles with lower profiles, such as sedans. A higher center of gravity means that there is a greater likelihood for the vehicle to tip over during sharp turns or impacts, especially in situations where uneven terrain is present or when involved in collisions with other vehicles.

While speed and the shape of the structure can certainly influence the dynamics of an accident and potentially contribute to the risk of rolling, they are secondary to the fundamental physics involved with the vehicle's height and center of gravity. Therefore, the design of SUVs, emphasizing their elevated stance, is the most critical factor in their propensity to roll during accidents. This is particularly evident in rollover crash tests, which specifically highlight how SUVs respond under different conditions compared to other vehicle types.
