Drivers were urged to take extra care as the first widespread snowfall of winter was due to hit many parts of Scotland.
About two-and-a-half inches of snow was forecast to fall in many areas, but rain and sleet was expected to wash it away as snow sweeps from west to east this morning.
Transport Scotland chaired a conference with police, forecasters and transport operating companies to ensure any problems caused by the snow can be dealt with.
Drivers were also being warned to watch out for ice on the roads as temperatures remain low.
Thermometers in central Scotland fell as low as -6˚C yesterday morning but it was coldest at Loch Glascarnoch, in Caithness, where an over night temperature of -8.2˚C was recorded.
Gemma Plumb, a forecaster with MeteoGroup, said: "In low areas there could be up to 5cm of snowfall, but sleet and rain is due to follow the snow and looks likely to wash most of it away from low areas, particularly in the west and central parts of the country.
"By morning the showers will be along the east coast and pushing into the north of Scotland.
"More snow could be due to fall on Wednesday night into Thursday, but again it seems that higher parts, 250m or so above sea level, will be most likely to see it lying."
Transport Scotland's network manager Stewart Leggett said: "As this is expected to be the first widespread snow of the winter, our Multi Agency Response Team (Mart) will be operational to monitor how the transport network is coping.
"We are working alongside police, operating companies, the rail industry and other key responders ahead of the Monday morning peak to ensure preparations are in place.
"We would urge people to be extra careful in icy conditions. This is a timely opportunity to remind the public of the wide range of advice that's available, including live travel information and tips on preparing for and driving in bad weather.
"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."
The snowfall is good news for Scotland's ski centres. Cairngorm and the Lecht, near Aberdeen, opened for business at the weekend reporting good snow cover.
Ms Plumb said up to 15cm could fall on higher ground in the next day, producing good conditions for snowsport enthusiasts.
The conditions will be a boost to business at the resorts, which saw limited skiing across much of Scotland at the start of this year.
Cairngorm did not close until the end of April due to a flurry of late snowfall over the slopes, but there was little snow cover earlier in the year.
