The best braking method to stop quickly is threshold braking. This technique involves applying the brakes firmly just short of locking the wheels. By maintaining optimal tire grip on the road surface, this method allows for maximum deceleration while retaining steering control. It is particularly effective in emergencies, as it combines stopping power with vehicle stability, enabling drivers to maneuver if necessary to avoid obstacles.

In contrast, pumping the brakes can be useful in certain situations, such as when driving on slippery surfaces, but it does not provide the rapid stopping power needed in emergency scenarios. Emergency braking refers to applying the brakes as hard as possible in a dangerous situation, which may lead to wheel lock-up and lost control if not executed with awareness of vehicle dynamics. Coasting to a stop, on the other hand, typically involves gradually reducing speed without using the brakes fully, which is less effective for quick halts when immediate stopping is essential. Thus, threshold braking emerges as the optimal choice for quick stops due to its balance of speed and control.
