Question

Difficulty: MediumEvasive Steering and Avoiding Collisions

At highway speeds, a commercial motor vehicle can almost always be steered around an unexpected obstacle in less distance than it takes to bring the vehicle to a complete stop.

Answer: Answer

Answer

True
The statement is correct because commercial motor vehicles require substantial distance to come to a complete halt due to vehicle mass, perception-reaction time, and air brake lag. In critical emergencies where stopping space is inadequate, steering around the hazard requires far less distance than stopping.

Step-by-Step Solution

1
Evaluate the physics of commercial motor vehicle stopping distance versus steering maneuverability at highway speeds.
Total stopping distance includes perception distance, reaction distance, brake lag, and effective braking distance, totaling several hundred feet at highway speeds.
Understanding total stopping distance establishes why stopping in sudden emergencies is often physically impossible within short gaps.
2
Compare the distance required to execute an evasive steering maneuver against the total stopping distance.
A commercial motor vehicle can clear an obstacle by moving laterally into an open space or adjacent path within a much shorter distance than the hundreds of feet required to come to a full stop.
The CDL manual explicitly highlights that you can almost always turn to miss an obstacle more quickly than you can stop.
3
Determine the truth value of the statement based on official CDL safety principles.
The statement is True.
Evasive steering is recognized as faster and requires less distance than complete braking when dealing with sudden road hazards.
