CDL · Night and weather
On a cold day, the temperature climbs just enough for ice on the road to start melting. What happens to the road surface?
Correct answer: It becomes more slippery than before.
Answer options
- AIt gives tires better grip as the ice softens
- BIt becomes safe for normal driving again
- CIt becomes more slippery than before Correct
Why
When ice starts to thaw, a thin film of water forms on its surface, and wet ice is much slicker than ice that is still frozen solid. Treat temperatures near the freezing point as especially dangerous: slow down and avoid abrupt braking or steering.
