When driving in snowy or icy conditions, extra caution is necessary on bridges and overpasses because they are more susceptible to freezing compared to regular road surfaces. This is primarily due to the fact that bridges and overpasses are exposed to cold air both above and below, leading to a quicker drop in temperature and causing these structures to freeze sooner than the ground-level roads, which maintain some warmth from the earth.

Because of this greater likelihood of ice formation, drivers should slow down and increase following distances when traversing these areas. Understanding the specific risks associated with different road types enables drivers to make informed decisions that enhance safety during inclement weather. While curves, intersections, and other road features also pose risks, none match the unique vulnerability of bridges and overpasses in freezing conditions.
