True or False: To prevent rolling back on an uphill grade, it’s okay to use your left foot on the brake while accelerating with your right foot.

Using your left foot on the brake while accelerating with your right foot is a technique often referred to as "brake torque" or "brake hold." This approach can be effective for preventing rollback on an uphill slope, particularly in vehicles that are equipped with an automatic transmission. By applying the brake with the left foot, you can keep the vehicle stationary while you simultaneously apply accelerator pressure with your right foot.

This technique is particularly useful in a school bus context, as it ensures safety by preventing the vehicle from rolling backward into traffic or other hazards when transitioning from a stop to moving uphill. It’s important to note, however, that this method requires practice and caution to ensure smooth transitions and to prevent unintended acceleration or stalling.

In contrast, for manual transmissions, the process involves using the clutch instead of the brake, and it may not always be feasible or safe to use both feet in the same manner as with an automatic vehicle. Overall, understanding when and how to apply these techniques is crucial for safe driving, especially in the context of transporting passengers in a school bus.
