What should you do while braking during mountain driving to ensure safety?

Apply just enough brake to slow down
Brake hard as soon as you start descending
Use cruise control
Ignore the escape route if you miss it

The correct answer is: Apply just enough brake to slow down

When driving in mountain conditions, applying just enough brake to slow down is essential for maintaining control of the vehicle and ensuring safety. This approach allows drivers to manage their speed without overheating the brakes, which can lead to reduced braking effectiveness. In mountain driving, where steep grades are common, using excessive braking can cause brakes to become too hot, potentially leading to brake failure. Additionally, this technique allows for a more gradual descent and offers greater control over the vehicle, preventing sudden stops that could destabilize the truck on a slope. It also prepares the driver to react effectively to changing conditions on the road or any obstacles that might appear. The other options pose risks; braking hard can cause skidding or loss of control, using cruise control is dangerous on steep grades as it does not allow for immediate adjustments in speed, and ignoring an escape route can lead to serious accidents in emergency situations.
