Vehicles are getting into difficulty on treacherous roads in parts of Derbyshire, according to emergency services.
A spokesman for Derbyshire fire service said vehicles are becoming stuck and skidding on snowy, icy routes in the Buxton and Matlock areas.
The spokesman urged motorists in these areas to consider whether their journey is really necessary.
If they do head out, the spokesman added, they should be prepared and drive with extra care.
At about 8.50am today, firefighters were called to Chapel Road in Whaley Bridge after a car left the route and crashed into a nearby field.
Crews rescued a woman who was trapped in the car. She was treated by paramedics.

However, bitterly cold, strong winds are making make it feel below freezing.
Overnight and into Sunday, temperatures are expected to plunge to -2C with some scattered wintry showers.
