When driving in fog, it is essential to prioritize visibility and safety. Using low beams is appropriate because they provide better illumination of the road immediately in front of you and reduce the amount of light that reflects off the fog, which can create a blinding effect. High beams can mistakenly enhance the visibility issues caused by fog, as the light will bounce back and create a glare, making it more difficult to see.

Slowing down is equally crucial, as conditions can be unpredictable in fog, which impairs your ability to see other vehicles, pedestrians, and road signs. This allows for a more cautious approach and gives you more time to react to any situations that may arise.

Hazard lights are generally used to indicate a vehicle that is stationary or to warn other drivers of a potential hazard, but they do not enhance visibility in foggy conditions. Adhering to speed limits without considering the weather conditions can also be dangerous, as safe driving speeds should always adjust according to the environment and visibility.

Therefore, the combination of slowing down and utilizing low beam headlights represents an effective strategy for maintaining safety while driving in fog.
