Which clue suggests black ice may be forming?
- A.Traffic is moving at normal speed
- B.The road looks dry and dusty
- C.The pavement looks wet when temperatures are near or below freezing, and ice is forming on mirrors or antennas
- D.Other trucks are using chains
Correct answer
C. The pavement looks wet when temperatures are near or below freezing, and ice is forming on mirrors or antennas
Why
Black ice is a thin, clear layer that makes the road look merely wet, and bridges and shaded spots freeze first. Ice building on your mirrors or antenna is an early personal warning to slow down before traction disappears.
