With warnings of ice on the roads, Superintendent Grenville Wilson of Sussex Police's operations department has warned drivers to change their habits to fit the conditions.
He said: "Drivers are reminded to check the weather forecast for the entire length of your journey before setting out and only make a journey if absolutely necessary.
"Completely clear your windscreen of ice and snow before driving and check that your vehicle's lights are working.
"Carry an emergency pack in your boot - a first aid kit, torch, blanket, food and drink, a tow rope and shovel could all come in useful if you do find yourself getting stuck. Also make sure you have a fully charged mobile phone and water proof shoes.
"When driving in snow and ice you will need to change the way you drive. Your vehicle will not start, stop or steer in the same way it usually does.
"Stopping distances are greatly increased in icy conditions, so slow down and keep a bigger distance between you and the vehicle in front. Brake or accelerate carefully and gradually, and take corners very slowly."
