The Michigan State Police reports that last year, about 40.7% of deadly traffic crashes involved drugs and/or alcohol.

But at the same time, according to Brian Swift of the National Alliance to Stop Impaired Driving, oral testing devices to detect recent substance use are sitting on shelves, collecting dust and unable to be used because they're not legally binding right now in Michigan.
