Gloucestershire County Council's gritting teams are preparing to go out again tonight as temperatures drop below freezing.
Forecasters are predicting temperatures to fall to -4 again tonight which means tomorrow morning is likely to be frosty.
The council's 33-strong team of gritters started a run this afternoon and they will be treating key routes around the county.
They will also be going out again during the night ahead of tomorrow morning's rush hour.
Although the threat of flooding has subsided, there are still some roads closed because of the recent wet weather.
Key routes closed are:
• A417 at Maisemore
• B4213 at Hawbridge
• Spittlegate Lane, Cirencester
Drivers are encouraged to take care on the roads, especially in rush hour.
Safer driving tips:
• Check that your car is up to the journey, tyres are correctly inflated and in good condition, and that your lights are clean and working properly.
• Ensure anti-freeze has been added to the radiator & that screen wash is of sufficient concentration.
• Tell a friend or relative where you are going.
• Take a flask of hot drink, torch, mobile phone (fully charged or with charger), blanket and appropriate outdoor clothing.
• Slow down on icy roads and leave a greater distance between you and the car in front.
• Check your route with such organisations as RAC Travel and AA Road-watch, and tune into local radio before you set out.
• If you get stuck in an isolated area, stay with your vehicle and remember that the engine should not be left running.
• Use your mobile phone if you need to access the emergency services for help.
