What should you do when driving in fog?

When driving in fog, using low beam headlights and reducing speed is crucial for several reasons. Low beam headlights are designed to illuminate the roadway directly in front of your vehicle without causing glare that can reflect off the fog, rain, or snow. High beam headlights, on the other hand, can create a "white wall" effect, reflecting off the fog and actually reducing your visibility even further.

Reducing speed is equally important in foggy conditions. Fog can drastically limit your visibility, making it harder to see other vehicles, pedestrians, or obstacles on the road. Slowing down allows for more reaction time and increases your ability to spot potential hazards in your path. It is essential to adjust your driving to match the visibility conditions to ensure your safety and the safety of others on the road.

Turning on hazard lights is typically not recommended while driving, as this could confuse other drivers into thinking you are stopped or experiencing an emergency. Using fog lights exclusively may not be sufficient if visibility is severely compromised, as they are intended to supplement low beams rather than replace them. Therefore, utilizing low beam headlights and operating at a reduced speed is the safest strategy when navigating through fog.
