What should drivers do during foggy conditions?

Answer: C — Use low beams and reduce speed

During foggy conditions, visibility is significantly reduced, making it essential to adjust driving habits for safety. Using low beams is crucial because high beams can create glare when reflected off water droplets in the fog, actually decreasing visibility instead of improving it. The low beams help to illuminate the road directly in front of the vehicle without causing this glare, allowing drivers to see better. Additionally, reducing speed is vital in foggy weather. Slower speeds give drivers more time to react to hazards that may suddenly appear, such as other vehicles, pedestrians, or obstacles on the road. Driving at normal speed in fog can lead to dangerous situations, as the ability to perceive distances and react appropriately is compromised due to limited visibility. Overall, the combination of using low beams and reducing speed is the safest approach to navigating through foggy conditions, helping to ensure the safety of the driver and others on the road.
