Mr Mackay said: "While this weather is not unusual in Scotland at this time of year, some areas are seeing their first snowfall of the season.
"A wide range of agencies and organisations are working together to implement their response plans with the aim of keeping disruption in difficult conditions to a minimum.
"The efforts being made by the team here at Scotland Transerv are being replicated by the trunk road operating companies across the country and the focused response to weather events will continue throughout the winter."
Mr Mackay said more salt was in stock than was used in the whole of last year and winter control rooms were ensuring routes were being treated and patrolled where and when needed.
He said motorists could see where gritters would be in operation via a map on the Traffic Scotland website with the latest information on its Twitter feed, smartphone app and internet radio.
