What should newer trucks do when going down long downhill grades?

Using a lower gear when going down long downhill grades is essential for maintaining control and preventing the vehicle from gaining excessive speed. This technique utilizes the engine's braking power, which helps slow the vehicle down without relying solely on the brake system.

When a truck is in a lower gear, it allows the engine to assist in decelerating the vehicle, reducing the risk of brake overheating and fading that can occur when brakes are continually applied downhill. This method promotes safer driving practices, particularly in a heavy vehicle where maintaining control is critical. It ensures that the truck has the needed power and control to navigate steep declines without becoming unstable or losing traction.

For newer trucks, properly managing downhill speeds through gear selection is a crucial skill and contributes to overall roadway safety.
