On the heels of yet another winter storm, the DRPS has issued a warning to motorists about road conditions in Brock, Scugog and Uxbridge.

A social media post from the DRPS at 4:20 p.m. notes that some roads in North Durham are covered in black ice.

“Please drive with extreme caution,” it reads.

The posts notes that Highway 12 – from Myrtle to Highway 7A – is “shut down,” with traffic moving at 10 km/h.
