A 3-minute lesson from the Oregon course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Snow and ice cut your view and multiply your stopping distance. Everything you do — gas, brakes, steering — must be gentle. Oregon also has rules on chains and traction tires, and a season for studded tires.
Know the rule
On snow and ice, drive slower and leave more room ahead. Keep windows clear of snow, ice and fog, and don't use cruise control. When police or highway officials say driving is very hazardous, stay off the road.
Signs may require you to carry or use chains or traction tires. Because studded tires cause damage, drivers are encouraged to use chains or other traction tires instead. Requirements are at TripCheck.com.
It's 33°F and the road looks just wet. Near freezing is when roads are most slippery, and the bridge ahead may already be icy. Slow down before the bridge, keep your steering steady, and brake gently if needed.
Check your understanding
Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.
According to the handbook, roads are most slippery:
Only when temperatures are well below freezing
Only during heavy snowfall
Near the freezing point, not below it
Equally slippery at all cold temperatures
Answer: Near the freezing point, not below it
Near-freezing temperatures create the slickest conditions.
