What is another method, in addition to keeping the cargo low, to prevent a rollover?

Answer: B — Go slowly around turns

Going slowly around turns is crucial to prevent rollovers, particularly in combination vehicles. When a driver takes a turn at high speed, the centrifugal force can increase the risk of tipping over, especially if the vehicle is loaded. By reducing speed while navigating curves, the driver can maintain better control of the vehicle and minimize the likelihood of a rollover. This method is particularly important for vehicles with a higher center of gravity, as they are more susceptible to tipping. Maintaining a lower speed allows the driver to react more effectively to any unexpected situations or changes in the road conditions, ensuring a safer maneuver around corners.
