What should a truck driver do when approaching an extreme grade?

When a truck driver approaches an extreme grade, the most appropriate action is to bring the truck to a stop and shift into a lower gear. This practice is essential for maintaining control of the vehicle on steep inclines or declines. By stopping and shifting to a lower gear, the driver ensures that the engine provides maximum torque, which helps to maintain traction and control when navigating the grade.

Using a lower gear is crucial because it enhances the vehicle’s ability to climb steep elevations without losing power or momentum. In the case of descending, a lower gear helps to prevent the brakes from overheating, which could lead to brake failure. Being in gear allows for optimal engine braking, reducing the reliance solely on the service brakes and minimizing the risk of uncontrollable speed.

Maintaining safety while managing steep grades is a critical skill for truck drivers, and this strategy directly contributes to both the driver’s safety and the safety of others on the road.
