The safety of America's transportation systems hinges on effective drug and alcohol testing programs. This deep dive with host Joe Riley and guest Brandy Helveston, President of Straight Line Mobile Drug Testing, reveals how the Department of Transportation's testing regulations were born from tragedy and now protect millions.

Following devastating accidents in the late 1980s that claimed multiple lives, Congress established the comprehensive DOT testing framework that fundamentally transformed workplace safety across transportation sectors. Today, these regulations impact approximately 8 million employees working for 700,000 employers across trucking, aviation, rail, transit, and pipeline industries.

The conversation clarifies critical aspects of DOT compliance, from the five drug classes being tested (marijuana, cocaine, opioids, amphetamines, and PCP) to the six federally-mandated testing scenarios. Joe and Brandy explain why every DOT-regulated employer needs a trained Designated Employer Representative (DER), how supervisors must recognize impairment, and the severe penalties for non-compliance—including fines reaching $100,000 or complete operational shutdowns.

Transportation employers will particularly value the practical guidance on selecting qualified testing partners, understanding the differences between regulatory agencies, and navigating the specific requirements that apply to their industry. With oral fluid testing on the horizon and electronic record-keeping transforming compliance management, staying informed on these evolving regulations has never been more crucial.
