What are the two methods for an emergency stop?

• A. Threshold Braking and Squeeze Braking
• B. Threshold Braking and Stab Braking
• C. Stab Braking and Squeeze Braking
• D. Threshold Braking only

Answer: (B)

When you need to stop quickly, the goal is to brake as hard as possible without losing steering control. The two traditional emergency-stop methods are threshold braking and stab braking. Threshold braking means applying brake pressure up to the point just before the wheels would lock, keeping the tires at the edge of slip so you maintain steering and maximize friction. If the vehicle has ABS, you press firmly and let the ABS modulate the braking, effectively maintaining near-threshold grip. Stab braking is used on older or non-ABS systems: you press the brakes to the floor to lock the wheels, then release briefly to regain traction and reapply, repeating until you stop. Squeeze braking is a smoother technique that avoids wheel lock but doesn’t provide the quickest stop, so it isn’t the primary emergency-stop method here.
