Question: 1 / 400

What is true about driving conditions during bad weather?

Bridges freeze after roads

Roads are more slippery than bridges

Bridges will freeze before roads

The statement that bridges will freeze before roads is accurate because of the way heat is transferred and retained. Bridges are typically constructed with materials that allow them to cool down faster than regular road surfaces, which are more insulated by the surrounding ground. Since bridges have air circulating beneath them, they lose heat more quickly and can rely on ambient temperatures to reach freezing faster than roadways, which are often warmer due to the soil below them.

This phenomenon is particularly important for drivers to understand, especially in cold weather situations, as it indicates that bridge surfaces may become icy and hazardous before surrounding roadways do. Awareness of this can help in taking necessary precautions while driving in adverse conditions, ensuring safer travel.
