For effective control on steep hills, what is a recommended approach?

Using controlled braking techniques is essential for effective control on steep hills. This approach helps to manage the vehicle's speed without over-relying on the brakes, which can lead to overheating and reduced braking effectiveness. Controlled braking involves applying the brakes in a gradual and measured way, allowing the driver to maintain a safe speed while navigating steep descents.

This technique enables the driver to balance the vehicle's momentum and braking power, ensuring that the bus remains stable and does not gain excessive speed, which can increase the risk of losing control. It also helps to prolong the life of the braking system by avoiding continuous or harsh braking, which can lead to premature wear.

Other options, such as using emergency brakes or switching to neutral, may compromise safety by reducing control over the vehicle, while accelerating on a descent can dangerously increase speed without allowing for proper control. Therefore, employing controlled braking is the safest and most effective technique when descending steep hills.
