There’s a reason why OPP close highways in the north during bad weather, it’s because they’re too dangerous. And now the north’s OPP detachments are issuing an advisory to motorists to stay off closed highways. They say venturing onto a closed highway is a danger to you and your passengers. And if you abandon your vehicle because you can’t drive any further, you just made it tougher for crews to clear the roadway. Driving on a closed highway can result in a 110 dollar fine plus you’ll get hit with three demerit points on your license.
