Which of the following describes stab braking?

Constant pressure on the brakes
Flicking the brake pedal quickly
Applying brakes fully until wheels lock, then releasing
Gradual brake application

The correct answer is: Applying brakes fully until wheels lock, then releasing

Stab braking is a technique used primarily in emergency situations to stop a vehicle quickly, particularly in large trucks or trailers. This method involves applying the brakes fully until the wheels lock up, which helps to achieve maximum braking force quickly. Once the wheels are locked, the driver then releases the brakes momentarily to allow the wheels to start rolling again. This cycle can be repeated to maintain steering control while slowing the vehicle down effectively. This method is especially crucial because locked wheels can lead to a loss of steering ability, and by releasing the brakes, the driver can regain some control. The ability to steer is vital for navigating around obstacles while braking, making stab braking an effective technique for maintaining safety under pressure.
