When operating a commercial vehicle on a roadway with reduced traction, a driver must slow down to a safe speed before entering a curve rather than braking while turning, because braking in a curve on a slippery surface can easily cause the wheels to lock up and initiate a skid.
Cevap: Cevap
Cevap
True. A commercial driver must reduce speed to a safe level prior to entering a curve on slippery road surfaces, as braking during a turn can exceed available traction and trigger a dangerous skid.
The statement is true because commercial driving safety rules require completing all speed reductions prior to entering a curve. Applying brakes while turning on a low-traction roadway divides available tire adhesion between braking and lateral cornering forces, which can easily cause the wheels to lock up and trigger an unrecoverable skid.
