Drivers and those who own a Truma caravan water heater should take caution on roads over the next few weeks after the Met Office issued a severe weather warning.
People making journeys in the north and north-west regions of England and Scotland have been advised to take all necessary safety precautions to ensure that they and other road users remain safe, the Press Association reports.
According to forecasts, overnight snowfall in some areas will result in between two to five cm of snow on the ground and up to ten cm on higher landscapes.
The Scottish government's Transport minister Keith Brown said: "I would remind the public that wet and snow-affected roads can shield the hidden danger of black ice. Gritters will be out in force but require the necessary space to deal with snow."
He added that all motorists should "play their part" to ensure that journeys run smoothly and that vital safety precautions are in place.
Recent heavy rainfall has also resulted in warnings from weather forecast providers. Roads in some areas of Scotland have been deemed dangerous as the rainfall quickly turned to ice in low overnight temperatures.
