Emergency crews respond to several accidents within Calgary and on highways just outside Airdrie after a blast of snowfall made roads extremely slick.
A Jeep Wrangler rear-ended a Chevrolet pickup truck on Highway 567 just east of Airdrie, shutting down the route for two hours on Friday afternoon.
STARS airlifted a 68-year-old man with serious non-life threatening injuries, as well as a 47-year-old woman who suffered minor injuries.
The highway has since reopened, but motorists are being asked to use caution when driving between Crossfield and Calgary city limits.
There have also been at least three collisions on Deerfoot Trail between 7 a.m. and the early Friday afternoon.
"Drive for the conditions," said Carol Henke, a spokesperson for the Calgary Fire Department.
Drivers are also reminded to slow down when passing emergency vehicles.
"We actually had one incident this morning where a collision happened during another collision," said Henke. "Potentially, fire crews could be put at significant risk."
Henke said intersections are the most dangerous spots to drive through during winter.
"Yesterday we had a vehicle take a corner too fast and hit a garage," she said.
"It can happen so easily and if your vehicle isn't equipped with winter tires, or if you are driving too fast."
In the city, Henke reminds drivers to watch out for pedestrians especially during shorter daylight hours and that not all crosswalks are marked of have flashing lights.
