Ice and fog warning for Derbyshire
Motorists are being warned of possible hazardous driving conditions as freezing temperatures hit Derbyshire.
A Met Office yellow warning remains in place, with a risk of ice and freezing fog predicted across parts of the county.
Derbyshire County Council said keeping the main road network clear was a top priority.
It has also employed a team of contractors to help clear minor routes across the region.
Local farmers have also been helping the council to keep local roads clear of snow.
On Monday, more than 100 Derbyshire schools closed, with travel problems reported across the county.
Snow also closed the A6024 towards Holme Moss and the A57 Snake Pass.
There were also delays at East Midlands Airport after poor conditions closed the runway and affected more than 30 flights.
Most schools in the region reopened on Tuesday although six remain closed.
Motorists have been advised to approach the A38 in Sutton In Ashfield with care between junction 28 of the M1 and the B6139 Coxmoor Road junction due to black ice on the road.
Residents in some areas of Derbyshire have also complained of not receiving any post since last Thursday.
Morag Turnbull, Royal Mail spokeswoman said they had attempted to make deliveries where it was safe but the severe weather had made it impossible in some areas.
She added: "We apologise to customers who are experiencing delays to their deliveries in Derbyshire as a result of the severe winter weather conditions there.
"A range of measures have been put in place to ensure deliveries reach people as quickly as possible."
