Which of these statements is true about bad weather and driving conditions?

Rain makes roads less slippery
Bridges will freeze after roads
It is safer to drive fast in foggy conditions
Strong winds have no impact on vehicle control

The correct answer is: Bridges will freeze after roads

The statement that bridges will freeze after roads is correct due to the fact that bridges are typically exposed to air on both sides, which allows them to lose heat more quickly than roads that are insulated by the ground underneath. Consequently, when temperatures drop, bridges can become icy before the adjacent roadways do, presenting a significant hazard for drivers. Recognizing this difference is critical for safe driving in cold weather conditions. In contrast, the other statements are either misleading or incorrect. Rain actually causes roads to become more slippery due to a mixture of water and oil that surfaces, reducing traction. Driving fast in foggy conditions is dangerous as visibility is greatly reduced, making it challenging to react in time to obstacles. Strong winds can significantly impact vehicle control, especially for high-profile vehicles, as they can cause swaying or even force a vehicle off-course. Understanding these dynamics is crucial for maintaining safety while driving in adverse weather conditions.
