Stab braking involves the action of applying the brakes firmly to bring the vehicle to a stop in an emergency situation. This technique is specifically used in scenarios where there is a risk of skidding, particularly in slippery conditions. The process includes applying the brakes hard until the wheels lock up and then releasing them to regain traction, repeating this cycle until the vehicle comes to a complete stop. Maintaining steady pressure on the brakes is not aligned with the stab braking technique, as this could lead to a loss of control. Gradually applying brake pressure does not fit stab braking either, as it emphasizes rapid, firm applications to quickly manage the vehicle's speed. Using engine braking as a primary method is a different technique focused on reducing speed without using the brake pedal, and it does not involve the specific actions described in stab braking.
