Weather, Visibility & EmergenciesStandalone practice
After a winter storm the sun comes out, and most of the highway looks dry. Where should you still expect ice?
Correct answer: On bridges, overpasses, and shaded parts of the road
Why
Bridges and overpasses cool from above and below, and shaded areas get little sun, so ice can stay there after the rest of the road is clear. Black ice is almost invisible, so watch for sudden changes from wet to icy pavement, also at high fills, deep cuts, and near snow fences. Slow down before these spots and avoid sudden braking or steering.
