Which statement best describes the impact of overloading a CMV?

• A. It increases stopping distance, reduces acceleration, and can cause steering/control problems.
• B. It reduces fuel consumption and improves handling.
• C. It has no effect on braking or steering.
• D. It makes the vehicle lighter and easier to maneuver.

Answer: (A)

Overloading a CMV means the vehicle is carrying more weight than it was designed to handle, which directly harms braking, acceleration, and steering. The extra mass makes stopping harder because momentum is higher, so more distance and energy must be dissipated by the brakes; this can also overheat and reduce braking effectiveness. Acceleration suffers because the engine and drivetrain have to move a heavier vehicle, so it takes longer to speed up or to recover from a slowdown. Steering and handling get worse as the load increases the tire load and shifts weight, reducing grip and making the vehicle feel sluggish or less responsive to steering inputs. In combination, these effects raise the risk of loss of control, especially in emergencies or on curves and grades.
