Transport Minister Keith Brown said: "As the wintry weather continues, Transport Scotland stands ready to respond swiftly and appropriately. Our Multi Agency Response Team (MART) will monitor the difficult conditions and the Scottish Government's resilience team is also closely monitoring the situation to help deliver a co-ordinated response.
"Motorists and public transport users should factor the weather and high likelihood of disruption into their travel plans, staying abreast of live travel information by listening to local radio reports and checking online sources.
"While we have implemented a raft of improvements ranging from higher than ever salt stocks to a strengthened fleet of gritters, the public must play their part by making full used of the vast sources of communications available. Drivers should take the road conditions into consideration, leaving extra time for journeys if necessary.
"The Traffic Scotland Control Centre continues to monitor the travel situation very closely and the website, Variable Message Signs and internet radio will be used to provide up to date information as the situation develops. I would urge the public to stay vigilant and tuned to local radio reports and the Traffic Scotland website as circumstances could quickly change."
Assistant Chief Constable Allan Moffat, speaking on behalf of the Association of Chief Police Officers in Scotland, said: "If you are travelling, be prepared for the winter weather. Check conditions and travel advice before setting off and ensure that both you and your vehicle are adequately prepared for the journey. Allow yourself plenty of time and make sure that you have sufficient fuel and supplies such as warm clothing, food and water in case you are delayed. When you are out on the road, remain vigilant and continue listening to weather and travel reports."
