In fog or other low-visibility conditions, use low beams and reduce speed. High beams bounce off the fog and create glare, making it harder to see and for others to see you. Low beams illuminate the road at a closer range and minimize glare, helping you detect hazards more reliably. Slowing down gives you more time to react and increases your safety margin when you can’t see as far ahead. If your vehicle has fog lights, they can help in addition to low beams, but they don’t replace the need for proper headlights; hazard lights are not a substitute for driving safely in these conditions.
