On Monday this week visibility fell between 100-150m in most areas of the UK, caused by radiation fog that blanketed the whole of the country. Radiation fog is normal to form at this time of year with clear nights cooling the ground and air above it, reducing the ability for the air to hold moisture and allowing condensation to occur.
Foggy November weather can make the roads a nightmare for drivers, therefore we have created a list of handy tips to help you drive safely in the dangerous conditions.
1. Use your dimmed Lights (fog lights in very poor visibility)
To increase your visibility during the fog, switch on your lights, even if it is during the day they will help you navigate and alert other drivers around you. Use your dimmed headlights or use fog lights if visibility is below 100m (328ft) however avoid full-beam as you can pose a danger to other drivers on the road. Remember when using rear fog lights, if visibility starts to improve switch them off. It is incredibly dangerous to leave them on in clear air as other motorists will be dazzled by the very bright rear fog lights, especially at night.
2. Drive at a slower speed
You’ll most likely come across more traffic than usual but don’t be tempted to speed, over take or drive close to another car, leave at least 2 car lengths between you and the car in front in low visibility, be patient even if you’re running late for work or trying to get the kids to school. It is easy to misjudge speed and distance when driving through thick fog, therefore it is best to drive at a slower speed to be on the safe side.
3. Plan your routes
The roads won’t be closed like the airports, but expect to hit delays as slower cars can build up queues on busy routes. Plan ahead and allow yourself extra time to make your journey. Try to avoid windy country roads that are not well lit, as any sharp corners or exits can surprise you when there’s low visibility.
4. Switch on the demisters and wipers
Make sure that your windscreen and rear window are clear before setting off. In the cold damp mornings always check that your demisters are on and get rid of any standing moisture by switching the wipers on too. Any condensation or grime on the glass will further reduce your vision of the road.
5. Listen for traffic at junctions
When approaching a junction in the fog you may find it difficult to see other drivers emerging. The best precaution is to stop, wind down your windows and listen out for traffic before making a maneuverer. This can be very useful when driving on busy routes and coming across difficult junctions in fog.
