What is the recommended action when driving in fog?

• A. Turn on high-beam headlights
• B. Use low-beam headlights and reduce speed
• C. Drive at normal speeds
• D. Stay at a constant speed without changing lanes

Answer: (B)

Using low-beam headlights and reducing speed is the recommended action when driving in fog due to the unique visibility challenges that fog presents. High-beam headlights can create a glare when they reflect off the water particles in fog, making it even more difficult to see. In contrast, low-beam headlights illuminate the road directly in front of the vehicle and reduce the amount of light that reflects back at the driver, improving visibility under foggy conditions. Reducing speed is also crucial because fog significantly decreases sight distance. By driving more slowly, you give yourself more time to react to any obstacles or changes in traffic conditions that may not be easily visible because of the fog. This combination of using low-beam headlights and driving at a reduced speed enhances safety for both the driver and other road users.
