What should the driver of a truck do when going downhill with a curve?

• A. Use a lower gear.
• B. Pump the brakes when reaching the curve.
• C. Brake firmly and steadily.
• D. Speed up slightly on the curve to maintain control of the truck.

Answer: (A)

Using a lower gear when going downhill with a curve is essential for maintaining control of a truck. When descending a hill, especially one that curves, gravity increases the risk of the truck gaining excessive speed. Engaging a lower gear helps to utilize engine braking, which can slow down the vehicle without solely relying on the brakes. This is particularly important for large trucks that can have longer stopping distances and are heavier, making them more challenging to control. Additionally, a lower gear helps to stabilize the vehicle as it navigates the curve, reducing the likelihood of skidding or losing control due to an increased speed. Proper gear selection is a key aspect of safe driving in hilly terrain and ensures that drivers can respond effectively to any changes in the road or vehicle performance.
