Commercial drivers must adjust their driving behavior based on pavement traction and environmental conditions. Match each hazardous roadway condition with the mandated speed adjustment or vehicle control action.
- Wet roadway surfaceReduce operating speed by approximately one-third ()
- Packed snow covering the roadReduce operating speed by one-half () or more
- Road surface covered in solid iceSlow down to a crawl and stop driving as soon as safely possible
- Hydroplaning in standing waterRelease the accelerator and push in the clutch without applying the brakes
Answer
Wet roadway surface matches with reducing operating speed by approximately one-third (); Packed snow covering the road matches with reducing operating speed by one-half () or more; Road surface covered in solid ice matches with slowing down to a crawl and stopping as soon as safely possible; Hydroplaning in standing water matches with releasing the accelerator and pushing in the clutch without applying the brakes.
Each roadway condition corresponds to a specific CDL standard: wet pavement requires a one-third speed reduction; packed snow requires reducing speed by half or more; icy conditions necessitate crawling and stopping; and hydroplaning requires releasing the throttle and disengaging the driveline with the clutch without braking.
