Final answer:
To prevent a rollover, a driver should keep the cargo as close to the ground as possible and drive at a slower speed.
Step-by-step explanation:
There are two things that a driver can do to prevent a rollover:
- Keep the cargo as close to the ground as possible - This lowers the center of gravity, making the vehicle more stable.
- Drive at a slower speed - Higher speeds increase the risk of a rollover because they reduce the time available for the driver to react to obstacles or sudden maneuvers.
Out of the given options, the correct answer is 1) Drive at a slower speed. Increasing the cargo weight or using a larger vehicle does not necessarily prevent a rollover.
