'Travel not recommended' warnings were issued for many Saskatchewan highways on Monday morning.

At 8 a.m. CST, large sections of the Trans-Canada Highway from Whitewood in the east to the Alberta border in the west had ice, swirling snow or drifting snow. 

In general, travel was not recommended — strongly advised, the Highways Hotline said — for highways around Regina, including Lumsden, Qu'Appelle and the Findlater areas.

Particularly bad were routes around Swift Current, Estevan and Moose Jaw.

Northwest of Saskatoon, sections of Highway 16 near Langham were icy or slippery, with swirling snow and snow drifts.

Some of the warnings were later dropped, but amid slippery conditions, a variety of cars and trucks ended up in the ditch.

Conditions were changing rapidly so people heading out were advised to check the Highway Hotline.
