Which lights should you use while driving in fog?

When driving in fog, using front fog lights and red rear fog lights is the most effective choice. Fog lights are designed to emit a wide, low beam of light that helps illuminate the road immediately in front of your vehicle without causing glare. This is crucial in foggy conditions, as high beams tend to reflect off the moisture in the air, which can actually reduce visibility.

Additionally, red rear fog lights help make your vehicle more visible to drivers behind you, ensuring that they can see you in low visibility situations. This combination of lights enhances safety by providing better illumination for yourself and increasing your visibility to others on the road.

Standard headlights, while useful in general driving, do not have the specialized design of fog lights, making them less effective in such conditions. Hazard lights, on the other hand, should only be used when your vehicle is stationary or in emergency situations, as using them while driving can confuse other road users.
