On a cold, wet morning, most of the road just looks wet. Where are you most likely to find ice first?
Correct answer: On bridges, overpasses and shaded areas.
Why
Bridges and overpasses have cold air above and below them and no earth underneath to hold heat, so they can ice over while the rest of the road is only wet. Shady spots also freeze first and dry out last. Near the freezing point, ice can be wet on top, which makes it even more slippery, so slow down before you reach these areas.
