Final answer:
New drivers commonly make the mistake of pushing the gas pedal instead of the brake while stopping.
Step-by-step explanation:
One common mistake new drivers make while stopping is pushing the gas pedal instead of the brake. This can happen when drivers are not familiar with the pedal placement and accidentally press on the gas instead of the brake, causing the car to accelerate instead of slowing down. It is important for new drivers to practice proper pedal control and familiarize themselves with the layout of the pedals to avoid this mistake.
