Slow Down

The first and most critical step when driving in fog is to reduce your speed. Lower speeds give you more time to react to vehicles and obstacles that emerge from the fog. Even if you know the road well, fog can hide changes or hazards that have appeared since you last traveled the route.

Use Low-Beam Headlights and Fog Lights

High beams can reflect off the fog, creating a “white wall” effect that actually reduces visibility further. Low-beam headlights and, if your vehicle is equipped with them, fog lights, are designed to cut through fog and illuminate the road without causing glare.

Increase Following Distances

It’s harder to judge speed and distance in foggy conditions, so increase your following distance beyond the usual three-second rule. Extending this to five seconds—or even more in denser fog—gives you a safer buffer zone.

Minimize Distractions

Fog demands your full attention. Minimize distractions by turning down the radio, limiting conversations with passengers, and avoiding phone use. Your eyes and ears should be focused on the road and your surroundings.

Use Windshield Wipers and Defrosters

Fog can cause moisture to accumulate on your windshield and windows. Use your windshield wipers and defrosters to keep the glass clear and prevent condensation or ice from forming.

Listen for Traffic

Turn down your music and open your windows slightly at intersections to listen for approaching vehicles and pedestrians, as visibility is severely limited.

Signal Early

Use your turn signals earlier than usual to give other drivers more time to react to your actions. This is particularly important for turns and lane changes.

Watch for Stopped Vehicles

In foggy conditions, it’s harder to see stopped or slow-moving vehicles until you are close. Be especially vigilant and ready to stop.

Stay Focused on the Road

Keep your attention on the road and avoid looking directly into the fog, which can be disorienting. Use the right edge of the road or painted road markings as a guide.

Know When to Stop

If the fog becomes so thick that you can’t see well enough to drive safely, consider pulling over into a safe location and waiting until visibility improves. Make sure to turn on your hazard lights so that other drivers can see your vehicle.

Driving Safely in Fog

Fog can turn a familiar route into a challenging and potentially dangerous journey. By adapting your driving habits, using your vehicle’s features correctly, and exercising caution, you can significantly reduce the risk of accidents when driving in foggy conditions. Remember, the key to safe driving in fog is patience, preparation, and staying focused on the conditions around you.
