Commercial Drivers License Exam Prep

Answer: C - When operating a commercial vehicle on snow packed roads, drivers should reduce their speed by at least one-half. If driving 50 mph, reduce speed to 25 mph on snow packed roads. Snowy roads may require even more reduction in speed, depending on the condition of the road surface. The reduction in traction on snowy roads will increase stopping distances, increase skidding potential (especially on turns and curves) and can result in loss of control of the vehicle. If roads are icy, drivers should stop the vehicle as soon as safely possible.
