Difficulty: MediumStopping and Braking Procedures

When executing the controlled braking technique during an emergency stop, the driver applies the brakes as hard as possible without locking the wheels, allowing the vehicle to stop while maintaining directional steering control.

Answer: Answer

Answer

True: Controlled braking is the procedure of applying maximum braking pressure without locking the wheels so that steering control is maintained.
The statement is correct because official commercial driving safety standards define controlled braking as applying the brakes as hard as possible without locking the wheels, which preserves tire grip and steering control throughout the stop.

Step-by-Step Solution

1
Identify the core mechanism of the controlled braking procedure.
Controlled braking involves depressing the service brakes as hard as possible while keeping the wheels rolling just shy of lockup.
Maintaining wheel rotation ensures lateral traction for directional steering.
2
Compare the statement with standard commercial motor vehicle emergency braking procedures.
The statement accurately reflects the definition and operational goal of controlled braking.
Differentiating controlled braking from stab braking (which involves intentionally locking and quickly releasing the wheels) is critical for commercial vehicle control.
3
Determine the truth value of the statement.
The statement is true.
All operational criteria stated in the prompt conform to standard CDL emergency braking protocols.
