Comox Valley RCMP are urging drivers to slow down following seven motor vehicle incidents in two-and-a-half hours Tuesday morning.
One incident this morning was a collision requiring medical attention, police confirm.
While the road appear to be wet with temperatures being just below freezing, there is black ice on many roads and highways in the area.
Police add a good rule of thumb in weather conditions such as this is if drivers don't have to be on the road, stay home until temperatures rise and road conditions improve.
"At this time the Ministry of Highways is contemplating closing some roadways until conditions improve," said Comox Valley RCMP Insp. Tim Walton. "... at this time Highway 19 north of Horne Lake and south of Cooke Creek is closed due to treacherous road conditions."
