Freezing temperatures and rain led to at least 80 accidents on Scotland's roads on Saturday night and Sunday morning.
Police described the conditions as treacherous
Police in the central belt, the Borders, Dumfries and Galloway and the Highlands dealt with numerous crashes.
However, there were no reports of serious injuries on one of the coldest November nights in recent years.
The M8 was closed for about two hours on Sunday morning to allow damaged cars to be cleared and gritting to proceed.
Central Scotland Police had warned drivers to avoid travelling unless absolutely necessary.
The M80 was reduced to one lane at the Castlecary Viaduct.
Inspector John Eggo of Central Scotland Police said: "Freezing rain is the worst possible conditions you can face as a driver.
"We're very fortunate that it was a Sunday morning and not a Monday"
Dumfries and Galloway, the Highlands and the Borders were also affected by the bad weather.
Drivers heading south found that the M6 was closed in both directions between junctions 37 and 40, from Kendal to Penrith, but it reopened before midday.
Temperatures were reported to be lowest in the Highlands overnight, with Kinbrace, in Sutherland, registering -13.2 degrees Celsius.
There were also very low temperatures in Aberdeen and Aviemore.
