OTTAWA -- The Supreme Court of Canada has agreed to hear a pair of cases involving drivers stopped by police at roadside checks.

One of the cases involves a British Columbia man who got a warning reading after blowing into a roadside screening device.

Lee Michael Wilson received a three-day driving ban in September 2012 after the roadside device registered a blood-alcohol level in the warning range.

He took the issue to the B.C. Supreme Court, which dismissed the roadside prohibition, saying there was no evidence indicating Wilson's ability to drive was affected by alcohol.

But the B.C. Court of Appeal later overturned the lower court's ruling.

The other case involves six B.C. drivers who either refused to give a breath sample or registered a fail on a roadside screening device.

They challenged the province's automatic roadside prohibitions for those who blow over .08 on a screening device.
