Which device must you have your foot on when shifting from parking gear to a driving gear?

When shifting from parking gear to a driving gear, it is essential to keep your foot on the brake pedal. This action is a crucial safety measure that prevents the vehicle from rolling unexpectedly and ensures that you have control over the vehicle while changing gears. Activating the brake pedal allows you to secure the vehicle in place, providing a stable base for the transition between gears.

Using the brake pedal is especially important in automatic transmission vehicles, where the vehicle must be in a stationary position before changing from park to drive or reverse. This helps avoid potential accidents and enhances safety for both the driver and surrounding individuals.

In contrast, the accelerator pedal is not involved in this process, as you are not accelerating when making the gear change from park to drive. The clutch is relevant primarily in manual transmission vehicles and doesn't apply to the question regarding automatic transmissions. Similarly, while the gear shifter is the tool you manipulate to change gears, it does not provide the necessary control and safety that the brake pedal does during this operation.
