When visibility is reduced due to fog, it is crucial to prioritize safety by adjusting your driving techniques. Using low beam headlights is the correct approach because high beam headlights can actually reflect off the fog and create a glare that impairs visibility even more. Low beam headlights illuminate the roadway directly in front of the vehicle without causing excessive glare.

Slowing down is equally important because reduced visibility means that you may not see hazards, pedestrians, or other vehicles in time to react appropriately. By reducing your speed, you give yourself more time to respond to any unexpected situations, helping to prevent accidents and ensuring a safer driving experience.

Turning off your headlights would leave you without any visibility to the road and other vehicles, which is highly unsafe. Maintaining your speed in foggy conditions can lead to dangerous situations, as stopping suddenly may be difficult if visibility is severely compromised. Therefore, using low beam headlights and slowing down is the most effective way to navigate through fog safely.
