Trump’s Marijuana Order Doesn’t Change Drug Testing For Safety-Sensitive Workers, At Least For Now, Transportation Department Says

DOT marijuana drug testing stays put: the rules don’t blink, even as rescheduling chatter grows loud

Out on the asphalt at 3 a.m., you learn to trust the rules that don’t flinch. DOT marijuana drug testing is one of those rules. Despite the headlines, despite the promise of a federal rethink, the U.S. Department of Transportation has made it clear: safety-sensitive workers still have to pee in the cup and pass the same old test. Pilots, school bus drivers, truckers, train engineers, subway operators, ship captains—the folks who keep the country moving—remain under the federal lens. After President Donald Trump signed an executive order nudging cannabis toward Schedule III, the department answered the rumble with a simple note: until Attorney General Pam Bondi finishes the rescheduling process, nothing changes. Marijuana is still Schedule I for these workers, and DOT’s guidance on medical marijuana, recreational use, and CBD still stands. The agency even underlined it in black-and-white on its site, saying it will keep monitoring and update the industry “as appropriate” while keeping the traveling public safe. If you want the official word, it lives here: DOT’s marijuana notice. The message? Keep your hands steady, your eyes forward, and your test clean.

The letter of the law, and the spirit of the highway

Here’s the fine print that matters. Even if cannabis shifts to Schedule III, DOT’s testing regime likely won’t budge. Why? The 1991 Omnibus Transportation Employee Testing Act gives the transportation secretary power to screen for any substance they believe threatens safety. Marijuana is named outright. That means the testing authority doesn’t hinge on which shelf the DEA puts cannabis on—it rests on whether the agency thinks weed endangers planes, trains, and 80,000-pound trucks barreling down I-80. Former Transportation Secretary Pete Buttigieg said as much last year: classification changes don’t automatically rewrite the rulebook. If you need a primary-source breadcrumb, DOT’s own materials sketch the logic clearly in an official interpretation linked from its public documents: a 1991 law that locks in discretion to test. And that’s why advocates keep warning that rescheduling is a floor, not a ceiling. Banking, sentencing, and workplace policy are different roads entirely—each with its own tolls.

Until Congress draws new lines, DOT will keep its own.

Impairment isn’t a number—it’s a moving target

Here’s the messy truth: THC in your blood doesn’t behave like whiskey in your veins. Federal researchers have said there’s no neat, linear line between blood THC concentration and real-world impairment. Heavy users can carry lingering metabolites long after the buzz is gone; infrequent users can feel sharper effects at lower levels. That uncertainty makes “per se” limits feel like trying to measure jazz with a ruler. Safety advocates, trucking groups, and regulators all circle the same campfire: we need better tools to detect impairment on the road, not just presence in the bloodstream. Meanwhile, zero-tolerance remains the blunt instrument because it’s easy to administer and hard to argue with in a courtroom. But look beyond the highway shoulder and you can see how fuzzy lines invite overreach. Hemp businesses—legal under federal law—have been caught in the crosshairs when enforcement can’t tell compliant products from contraband in real time. That tension bubbled up in court in the plains, as captured in Kansas Attorney General And Law Enforcement Sued Over Raids On Hemp Businesses. Different substances, same knot: the science, the law, and the street-level reality don’t always sing in harmony.

Fifty laboratories, one interstate

America loves a patchwork. One state softens; another tightens. While Washington inches toward Schedule III, Massachusetts is flirting with the opposite tug—rolling back parts of its system, re-stirring the pot of what voters thought was settled. Watch the on-the-ground maneuvers in Massachusetts Campaign To Scale Back Marijuana Legalization Has Enough Signatures To Advance Toward Ballot, Officials Say. Head south and you’ll find a different frontier entirely: a push to normalize psychedelic therapy, a sign that regulated access to once-taboo compounds is entering mainstream rooms with dim lights and real clinical guardrails. That current gets a fresh pulse in New Jersey Bill To Legalize Psilocybin Therapy Clears Another Assembly Committee. All the while, DOT’s domain spans the whole map. The truck leaving Fresno, the jet out of Newark, the school bus in Kalamazoo—they cross borders and regulatory philosophies in an afternoon. That’s why federal uniformity, for better or worse, still sets the tone for workers whose mistakes make the evening news.

The road ahead: clarity beats vibes

So where does that leave the night crew? With a rule that doesn’t blink. DOT says it will keep the testing and the guidance as-is until rescheduling is finalized—and even then, don’t expect a sea change without explicit action. The agency may tweak terminology around THC, hone the paperwork, and keep the safety drumbeat steady. But the heart of the policy—the expectation of sobriety on duty—remains stubbornly intact. That’s not culture war; that’s institutional muscle memory. If we’re serious about both safety and fairness, the next chapter has to be about smarter impairment tools and clearer lines—science that measures whether you’re fit to drive now, not what you did last weekend. Until those tools arrive, workers in safety-sensitive jobs live by a simple gospel: know the policy, respect the test, and don’t gamble your livelihood on wishful thinking about Schedule III.
