DRIVERS in Gloucestershire and South Gloucestershire are being urged to take extra care on the roads ahead of forecasted heavy fog tonight and tomorrow.

The Met Office has issued a yellow warning for fog from 6pm tonight until 9am tomorrow morning, meaning drivers should plan ahead and think about possible travel delays.

Highways England is advising drivers to check their headlights and fog lights before setting out on journeys to make sure they are working properly, and adjust their speed to suit the conditions on the road.

Areas of fog are expected, including dense freezing fog pateches with visibility of less than 100 metres.

Stuart Lovatt, Highways England’s head of road user safety, said: “We’re expecting patches of fog to affect the rush hour this evening and tomorrow morning, so we’re advising drivers to take care and allow extra time for their journeys.

“Drivers should switch their headlights on when visibility is reduced – generally when you can’t see for more than 100 metres – and use fog lights if you’re struggling to see other vehicles. You shouldn’t use your lights on full beam as the fog can reflect the light back and reduce visibility.

“We’d also encourage drivers to check their lights before setting out and make sure they know how to operate their front and rear fog lights.”

Among advice being issued by Highways England, drivers are reminded to keep a safe distance behind the vehicle in front and be able to stop well within the distance you can see clearly.

They are also reminded to make good use of windscreen wipers, central heating and demisters.
