Using the parking brake to hold the vehicle until the clutch engages is a crucial technique when starting a heavy vehicle on an uphill grade. This method is effective because it prevents the vehicle from rolling backward, which can be a significant risk when transitioning from a stationary position to moving uphill. Engaging the parking brake stabilizes the vehicle, allowing the driver to find the right balance between the clutch and throttle without the fear of rolling back.

Once the driver feels the clutch begin to engage, they can gradually release the parking brake while simultaneously applying pressure to the accelerator. This coordinated action helps ensure a smooth transition from a standstill to moving forward on an incline. Uphill starts can pose challenges, especially with heavier vehicles, making this technique an important rule for safety and control.

Other methods, such as shifting into a lower gear or releasing the clutch immediately, do not provide the same level of control and could result in a rollback or stalling, particularly on a steep incline. Each of these alternatives lacks the stability that using the parking brake provides during this critical phase of driving.
