Gritting lorries are out again as road temperatures fall
Gritting lorries are out in force again on Devon and Cornwall's roads, with more wintry showers expected together with sub-zero temperatures.
On Tuesday some areas in the north and west were covered in 4in (10cm) of snow and military rescue helicopters were used to assist ambulance services.
Snow and ice made many roads impassable and parts of the A30 and A39 were blocked by a series of accidents.
Vehicles were also stuck in snow on the Devon/Dorset border near Lyme Regis.
Police said some had broken down on the A3052 Sidmouth Road, blocking it both ways.
Drivers have been urged not to go out unless absolutely necessary.
The Highways Agency, which is responsible for the A30 and A38, said motorists should avoid driving over higher ground like Dartmoor and Bodmin Moor, as snow may accumulate very rapidly, stranding vehicles.

The eastbound carriageway of the A30 at Plusha near Launceston was covered with heavy snow and only one lane of the westbound carriageway was open.
Lorries came to a halt on the A30 at Bolventor, Lifton and Launceston.
The A39 between Camelford and Bude was almost impassable and four vehicles were stuck in the snow at Polyphant near Launceston.
The St Mawes passenger ferry near Falmouth was also a victim of the weather.
In Devon about 350 elderly people did not receive home help after Primecare, a County Council contractor, said the roads were too dangerous to venture out on.
All North Cornwall District Council leisure centres were closed and refuse collections were postponed.
Refuse collections were also cancelled in west Devon, Torridge in north Devon and they have been disrupted in the Teignbridge area of south Devon.
