A bill introduced this week into the House by Wisconsin Republican Reid Ribble would force the U.S. Department of Transportation’s hand on making carriers use hair samples to test truckers for drug use as opposed to urine samples if made law. The bill requires that the DOT implement a pilot program to evaluate drug testing via hair vs. drug testing via urine.
Some larger trucking companies and the American Trucking Association have pushed for a hair sample mandate for years and some fleets have implemented them independently.

Affected trucks include model year 2008-2018 Freightliner Cascadia and Western Star 4700, 4900, 5700 and 6900 trucks. DTNA says after hard brake applications, the brake light pressure switch may not activate the brake lights with the light application of the brake pedal.
