• Before setting off, clean your windows and windscreen and ensure all your lights are working.
• Let others know you are likely to be delayed.
• When you’re ready to leave, switch on the dipped headlights. Only use front and rear fog lights where visibility is less than 100 metres.
• Use your windscreen wipers on an intermittent setting to clear the fine mist that collects on there.
• Slow down and keep enough distance between yourself and the vehicle in front. Make sure you can stop safely within the distance you can see clearly.
• Avoid relying on the vehicle in front as a guide to hazards ahead. Fog makes it more difficult to judge how hard vehicles are braking and they might be slow to react.
• Brake gently but earlier than usual so your brake lights warn drivers behind.
• At junctions, wind the window down and listen for traffic.
• Take high-viz clothing in case you have to leave the car.
Elstow said: “Don’t underestimate the effect fog has on your perception of speed. Adjusting your driving to the weather conditions will help you to become a better driver.”
