Police are warning the public of treacherous driving conditions which are expected tonight [Monday 19 March] through to tomorrow morning.
A Yellow Weather Warning is in place across Devon and Cornwall for ice from 7 pm tonight through to 9 am tomorrow.
Areas of Devon and Cornwall have seen significant snowfall causing challenging conditions and disruption on the road network, with a number of collisions and abandoned vehicles causing further problems.
Police advice is to avoid travel in the hours of darkness and to take heed weather warning for ice which will make travelling potentially dangerous.
We are also advising the public who are travelling on foot to be careful as it will become extremely slippery underfoot.
A lot of rural routes are impassable at present and Exmoor, Lynton, Lynmouth and Coombe Martin are currently cut off. Devon Highways and partners are working hard to clear the roads and enable access to these areas.
We are also asking motorists to avoid the moors today and tomorrow due to the dangerous driving conditions.
Primary routes are currently passable with care.
The multi-agency operation to keep roads as clear as possible via gritting and ploughing continues. Temperatures will remain low today and tomorrow making driving conditions treacherous due to ice.
We have been working with partner agencies all weekend to keep people safe and main routes open, however, our advice is still for motorists not to travel unless essential. If you have to travel, carry additional warm clothing/footwear, food, drink, a charged mobile phone, and ensure your vehicle has a full tank of fuel.
We would like to thank the public, volunteers and partners once again for all of their assistance, co-operation and hard work over the past few days.
