Commercial motor vehicle traction varies dramatically across different adverse weather and roadway conditions. Match each roadway condition on the left with its mandatory CDL speed adjustment or vehicle management rule on the right.
- Wet road surfaceReduce speed by at least one-third ()
- Packed snow surfaceReduce speed by one-half () or more
- Icy road surfaceReduce speed to a crawl and safely stop as soon as possible
- Hydroplaning occurrenceEase off the accelerator gradually and avoid braking until tires regain contact
Cevap
Wet road surface pairs with reducing speed by at least one-third; Packed snow surface pairs with reducing speed by one-half or more; Icy road surface pairs with reducing speed to a crawl and safely stopping; Hydroplaning occurrence pairs with easing off the accelerator and avoiding braking until tires regain contact.
CDL safety regulations establish specific operational rules for each traction level: reduce speed by about one-third on wet roads, reduce speed by one-half or more on packed snow, reduce speed to a crawl and park on ice, and release the accelerator without braking when encountering hydroplaning.
Adım Adım Çözüm
Anahtar Kavram
Standard commercial driving speed reductions and emergency control actions across various low-traction road conditions.
