Match each hazardous road or driving condition with the corresponding mandatory speed adjustment procedure mandated for commercial motor vehicles.
- Wet road surface from rainReduce speed by about one-third of the normal driving speed
- Packed snow covering the roadwayReduce speed by one-half or more
- Icy roadway / glaze iceSlow down to a crawl and stop driving as soon as safely possible
- Approaching a sharp curveReduce speed before entry; avoid braking while turning
Answer
Wet road surface matches reducing speed by about one-third; packed snow matches reducing speed by one-half or more; icy roadway matches slowing to a crawl and stopping safely; approaching a sharp curve matches reducing speed before entry without braking in the turn.
Each road surface condition demands a specific proportional speed reduction according to commercial vehicle safety standards: wet pavement requires a 1/3 reduction, packed snow requires at least a 1/2 reduction, ice necessitates slowing to a crawl, and curves require speed management prior to entry.
