When starting a loaded bus from a stop on a steep incline, which technique is advisable with a manual transmission?

Starting a loaded bus from a stop on a steep incline requires careful coordination of the clutch, accelerator, and brakes to prevent the vehicle from rolling back. The correct technique involves slowly releasing the clutch while also releasing the parking brakes. This method allows the driver to smoothly engage the engine power without losing control of the bus.

As the clutch is engaged gradually, the engine is connected to the wheels, providing the necessary power to move forward. Doing this slowly helps ensure that there's enough power to prevent rollback while allowing for a smoother transition from stationary to moving. It's crucial in this situation because the bus is loaded, making it heavier and more difficult to start moving on an incline.

Utilizing the other techniques mentioned would not effectively address the challenges of starting on a steep incline. Quickly shifting to a higher gear would not provide enough power to start moving uphill, while releasing the parking brakes while accelerating could lead to a loss of control. Using the handbrake to prevent rolling back could be useful, but primarily, the proper technique is to manage both the clutch and the accelerator while disengaging the brakes to ensure a safe and effective start.
