Show answer

Correct answer to question 89 (Tank Vehicles): It can shift weight toward one side of the vehicle, increasing the risk of a rollover

Why

When surge pushes liquid toward one side of the tank during a turn or lane change, it shifts weight in that direction, which can raise the risk of a rollover if not managed with a smooth, controlled maneuver.
