Drivers continue to turn a blind eye to road closed signs.
According to OPP, amid snow and blowing snow on Saturday, five police cruisers were hit from behind by drivers who chose to ignore road closures.
The cruisers were hit as police responded to collisions in Huron, Perth, South Bruce and Middlesex counties in the evening.
The roads were closed as a winter storm created whiteout conditions that reduced visibility to zero or near zero.
During the thick of it parts of highways 4, 7, 21, and 23 were closed.
"When you see that road closed sign, it's there for a reason," Sergeant Ed Sanchuk said in a video posted to social media. "You're not only putting yourself in jeopardy, you're putting first responders and those innocent motorists that are already in the ditch... in jeopardy as well."
Sanchuk went on to remind drivers that if you go around a closure sign and get into a collision insurance companies are unlikely to cover the cost of damages to your vehicle or damages to any property.
"We just want people to use common sense. Don't put yourself in unnecessary jeopardy. If the road is closed do not go around that sign. They are big signs that you cannot miss," said Sanchuk.
At one point during the storm drivers were advised to stay off the road entirely in Huron and Perth. Police were called to multiple crashes and vehicles in ditches.
No serious injuries were reported.
