Glasgow and much of the west of Scotland woke up to a blanket of snow, with The Met Office warning that winter weather will continue to cause problems.
All routes around the city were passable, but sections of the M8 and M74 were slow moving during rush hour. Forecasters had predicted a cold snap and drivers were warned to take extra care.
But earlier, a bus driver was taken to hospital after two buses crashed at Glasgow Cross, near the Saltmarket, at around 7.50am. A female driver was taken to Glasgow Royal Infirmary as a precaution.
In Greenock, a female driver was uninjured after her car left the road and crashed into a building, at around 9.25am, in Wellington Street.
The Met Office had issued yellow weather warnings for most of the country early in the morning, with up to 10cm of snow falling on higher ground.
The "be aware" alert for snow in Strathclyde has been extended to midnight.
Forecasters predict rain and subzero temperatures over the next few days.
A spokesman for the Met Office, said: "Snow will turn to rain from the west during this afternoon and evening.
"However, there will be a short period of rainfall onto sub-zero surfaces, mainly affecting routes above 200 metres, and leading to an enhanced risk of ice."
