What should you do when driving in foggy conditions?

Using low beam headlights and reducing speed is the safest approach when driving in foggy conditions. Fog significantly reduces visibility, making it difficult to see other vehicles, road signs, and potential hazards. Low beam headlights are designed to illuminate the road immediately in front of the vehicle without reflecting off the fog or mist, which high beams would do, causing glare and further obscuring visibility.

Reducing speed is essential because it allows the driver to react more effectively to unexpected obstacles, such as stopped traffic or pedestrians that may be hard to see. Traveling at a slower speed means that a driver has more time to make decisions and stop safely if necessary.

Choosing to avoid driving altogether can be prudent in severe fog, but it is not always a practical option depending on the circumstances. Additionally, keeping windows closed does not directly address the driving issue posed by fog but might be relevant for comfort in certain conditions. Overall, focusing on using low beam headlights and driving at a reduced speed directly targets the challenges posed by fog.
