Safety: Clear advice on driving in fog

Road safety charity the Institute of Advanced Motorists offers weekly motoring tips from Britain’s top advanced driver, Peter Rodger. This week he is advising motorists on how to drive in fog.

Peter said: “Fog is one of the most difficult conditions to drive in. Ensure you are prepared so that you can carry out your journey safely, and allow lots of extra time for the trip.”

Tips for driving in the fog:

l Before setting off, clean your windows and windscreen and ensure all your lights are working.

l When you’re ready to leave, switch on the dipped headlights. Use front and rear fog lights if visibility is less than 100 metres.

l Use your windscreen wipers on an intermittent setting to clear condensation.

l Switch the heater or air conditioning on and leave it running to keep the inside of the glass clear.

l 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.

l Fog is not the same density all the time – it may get thicker, slow down if it does.

l Brake gently but earlier than usual so your brake lights warn drivers behind.

l At junctions, wind the window down and listen for traffic.

l Take high-viz clothing in case you have to leave the car.

Peter said: “Don’t underestimate the effect fog has on your visibility. Adjusting your driving to the weather conditions will help you to become a better driver.”
