Icy pavements are causing treacherous conditions after temperatures plunged overnight.
After the heavy snowfall on Friday evening, the remaining snow has now turned to ice.
People walking through Nottingham city centre on Monday morning said they were having to watch their step.
Tricia Bowen, 44, of Carlton, said: "The pavements are a nightmare - it's very dangerous.
"You have to be very careful not to slip and it takes twice as long to get anywhere.
"Round where I live the side roads are very bad."
Semhar Fitsum, 27, of Sneinton, added: "All the snow is melting and leaving icy patches on the pavements.
"It's very slippery so you have to watch your step.
"I hope the council grits the pavements as well as the roads."
The Met Office has issued a severe weather warning for ice and is urging people to be prepared for freezing temperatures.
The chief forecaster said: "Showers currently over the North Sea are expected to drift across parts of England during this morning.
"With surfaces widely below freezing, this is expected to lead to icy stretches forming in places.
"Surface temperatures are expected to slowly rise through this morning to above freezing by 11am."
Nottinghamshire Police are warning drivers to take care on the roads - and only drive if absolutely necessary.
The force dealt with a number of car crashes over the weekend, particularly in the north of the county, where many roads appeared clear but were affected by black ice.
A spokesman said: "Officers are continuing to advise motorists to only travel where absolutely necessary and, if you are heading out, to watch your speed.
"Motorists should also beware of black ice on the roads, especially on bends or where the road is shaded by trees."
Across England, temperatures dipped to their lowest recorded levels of the year overnight.
Parts of the country saw temperatures as low as -7C.
However, those heading out for New Year's Eve celebrations on Wednesday night are in luck, as it is expected to become milder as the week goes on.
Temperatures are predicted to rise to as high as 6C.
And the start of 2015 is looking promising - with highs of 11C on Thursday.
