On a winter morning in the mountains, the road ahead is covered with ice. How should you set your speed?
Correct answer: Slow to a crawl, and put off the trip until the ice is gone if you can
Why
The manual gives a scale for slippery roads: about 10 mph slower on a wet road, half speed on packed snow, and a crawl on ice. Look for ice first in shady spots and on bridges and overpasses, which freeze before other pavement. Ice near the freezing point is wet, which makes it even more slippery than colder ice.
