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

  1. AIt gives tires better grip as the ice softens
  2. BIt becomes safe for normal driving again
  3. 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.
