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

Disengaging the clutch and coasting down a hill is not legal or safe in the context of operating a school bus. Coasting can lead to a loss of control over the vehicle, as it diminishes the driver's ability to use engine braking and limits the effectiveness of the vehicle's brakes. Maintaining control is crucial, especially in a large vehicle like a school bus that carries passengers.

Coasting could also result in situations where the bus could gain excessive speed or become difficult to maneuver, particularly in emergency situations where quick response is necessary. By keeping the clutch engaged and using appropriate gearing, the driver can enhance vehicle control and safety when descending a hill. Thus, coasting without maintaining engagement with the transmission is not allowed for safety reasons.
