Motorists in Dorset have been warned about driving in icy conditions - after dozens of accident over the past few days.
Temperatures are again set to drop this evening, and will remain frosty tomorrow morning.
Inspector Matt Butler of Dorset Police's Traffic Unit said: "Over the past two mornings, Dorset police has dealt with twenty separate collisions where the indication is that drivers have lost control in icy conditions.
"We have also seen vehicles involved in collisions where drivers have not cleared frost off their windscreens and windows sufficiently.
"I would ask drivers to plan ahead and allow themselves an extra few minutes to defrost their vehicle and then drive a little more slowly to ensure that they arrive safely at their destination.
"Remember many roads, particularly in rural areas, will not be gritted."
Drivers are being reminded to avoid sudden actions when roads are icy, to avoid losing control of their vehicle.
Motorists should drive slowly on bends, brake progressively on the straight before a bend and steer smoothly round the bend.
Council gritters will be out this evening - treating roads around Dorset.
A Dorset County Council spokesperson said: "With hundreds of kilometres of road in the Bournemouth and Poole area and thousands of kilometres in Dorset, it would be impossible to treat each and every single route.
"Therefore, road salting is planned according to a network of routes that carry the vast majority of traffic around Bournemouth, Poole and Dorset.
"These are primarily main roads, commuter routes, some bus routes, roads to the hospital and other emergency stations."
