Stein Connelly, head of transport resilience (operations) at Transport Scotland, said: “We’re working closely with our colleagues at the Met Office and transport operators to understand the impact of snow and ice across Scotland. We’re well prepared and have well established plans in place which are now in effect.
“This cold snap is already causing difficult driving conditions in the current warning areas, with further severe impacts anticipated on Tuesday as part of the existing warnings.
“It’s important that anyone that has to travel during the warning period plans their journey in advance and allows extra time.
“Police Scotland’s official travel advice is likely to change at short notice, so it’s important people check the news and follow social media accounts for the latest advice.
“If you have to travel, please drive to the conditions. Consider what kit you might need to keep in your car in the event of those difficult conditions.
“There may also be disruption on other modes of transport, so please check with your transport operator before setting off if you’re planning to travel by rail, ferry or air.”
