What should you do when driving in fog?

When driving in fog, using low beam headlights and reducing your speed is essential for safety. Low beam headlights are designed to provide better visibility in foggy conditions because they illuminate the road immediately in front of the vehicle without reflecting off the fog, rain, or snow. This helps reduce glare, allowing the driver to see better.

Speed reduction is crucial in fog to increase reaction time and to allow for better control of the vehicle. Fog can significantly reduce visibility, making it difficult to see other vehicles, traffic signals, and road signs, so driving at a slower pace enhances safety by providing drivers with the opportunity to react to unforeseen circumstances.

In contrast, using high beam headlights can create more glare, making visibility worse. Driving normally with hazard lights is not advisable either, as it may confuse other drivers about your intentions. Finally, turning off headlights altogether would severely impair visibility, making it extremely dangerous to drive in fog. Thus, the practice of using low beam headlights and reducing speed is the safest approach when navigating foggy conditions.
