Buses and bin lorries in Derbyshire face -15C
The freezing temperatures have been causing problems for a number of services across Derbyshire.
Bus firm Trent Barton said some of its drivers had reported temperatures of about -15C (5F) which had seen some vehicles freeze and lead to delays.
Waste collections in Derby and Amber Valley have been affected by freezing hydraulics and icy roads.
Royal Mail has also apologised for disruption to deliveries and said it was working to clear the backlog.
Mark Wilkinson from Royal Mail said: "We were experiencing up to two or three feet of snow last week and clearly that disrupted our services out to the public.
"Most walks will be going out today, albeit double manned to make sure we don't get stuck and people don't get themselves injured."
Amber Valley Borough Council said hydraulics on their refuse lorries were being affected but they were trying to get around as many houses as possible.
Residents have been advised they can put out extra waste next time if it was not collected this week.
Collections in Derby city have also been suspended as side roads are hazardous.
