When traveling downhill, is it legal to disengage the clutch and coast down the hill?

Explanation:
When it comes to the operation of a school bus or any commercial vehicle, disengaging the clutch and coasting downhill is considered unsafe and is therefore illegal. When a driver allows a vehicle to coast, they reduce their control over the vehicle, which can lead to dangerous situations, especially on steep or uneven terrain. Maintaining control of the vehicle is crucial, particularly when descending a hill. Drivers are responsible for managing their speed and ensuring they can respond effectively to any changing conditions on the road. Engaging the engine (by not coasting) provides better control, helping to prevent excessive speed and allowing the driver to utilize engine braking. Engine braking can aid in reducing speed without relying solely on the vehicle's brake system, which is essential to prevent brake overheating and potential failure. While some may think that coasting could save wear on brakes or fuel, the risk to safety and control far outweighs these perceived benefits. Therefore, engaging the clutch to coast downhill is strictly against regulations designed to ensure both the safety of the driver and passengers, as well as other road users.
