What are the two methods of emergency braking for a commercial driver?

The two methods of emergency braking for a commercial driver are controlled and stab braking. Controlled braking involves applying the brakes in a smooth manner to slow down the vehicle without causing it to lose traction. This technique allows the driver to maintain better control over the vehicle during a stop, which is crucial in emergency situations where steering control is essential.

On the other hand, stab braking is used when maximum braking power is required, often in situations where the brake system is at risk of locking up. In stab braking, the driver fully applies the brakes for a brief moment and then releases them, which helps to prevent wheel lockup and allows the driver to regain steering control if necessary.

These methods are critical for safely bringing a heavy commercial vehicle to a stop in emergency situations, showcasing the importance of proper braking technique in maintaining vehicle control and safety on the road. Understanding and practicing these techniques can significantly enhance a driver's ability to respond effectively to unexpected challenges.
