On freezing, wet days, which roadways are most likely to hide spots of ice?

• A. Under bridges and on overpasses
• B. In direct sunlight on open stretches
• C. In the wheel ruts
• D. On dry pavement

Answer: (A)

Ice on freezing, wet days tends to hide under bridges and overpasses. These structures are exposed to cold air from all sides and don’t get the same ground warmth that smooths pavement, so the surface stays colder and any water that runs onto them freezes more readily. Water can also drain away from regular pavement but pool and freeze on the undersides of bridges, creating hidden patches of ice that can surprise drivers. In direct sunlight on open stretches, the sun’s warmth helps melt any ice, so icy spots are less likely there. Wheel ruts can trap water and freeze, but they’re not as reliably icy as the shaded, cooler bridge areas. Dry pavement won’t be icy. Stay alert for bridges and overpasses on cold, wet days and slow down to give yourself time to react if you encounter hidden ice.
