In foggy conditions, what should drivers do?

In foggy conditions, drivers should use low beam headlights. Low beam headlights are designed to provide better visibility on the road in conditions where there is limited visibility, such as fog, rain, or snow. High beam headlights can create a glare that reflects off the fog and makes it even harder to see, as the light scatters in the fog, creating a white wall that obscures the driver's view. Keeping headlights off is not advisable, as it significantly reduces visibility for both the driver and any other vehicles on the road. Using hazard lights is also not an appropriate choice for driving in fog; they are intended to indicate a stopped vehicle or emergency situation but do not aid in visibility while driving. Therefore, utilizing low beam headlights is the correct and safest practice for navigating through fog.
