The Impact of Drugs & Alcohol in Trucking
Our recent webinar, “The Impact of Drugs & Alcohol in Trucking?” with SMSC Senior Safety Consultant Anne-Marie Naples and Learning and Development Specialist Ruth Bowdish, explored the serious risks substance abuse poses to drivers, public safety, and your business. Anne-Marie and Ruth walked through what DOT regulations require when a violation occurs, from the moment a driver is removed from duty to the long road back, and shared how the right policies and training can protect your fleet before an incident ever happens.

Key takeaways...
A violation triggers immediate removal — and the Clearinghouse makes it permanent and visible. Every positive test, refusal, and instance of actual knowledge is recorded, and SDLAs must begin downgrading the CDL or CLP within 60 days of notification. There is no quietly moving on to the next employer.
The SAP controls the path back, and their recommendations are binding. There is no second opinion and no provision for a second evaluation — the driver must complete the SAP's treatment or education plan, be re-evaluated, and pass an RTD test before performing any safety-sensitive function.
Return to duty isn't the finish line — the follow-up testing plan is. At least six unannounced tests in the first 12 months, extendable up to five years, held by the employer and never disclosed to the driver.
State legalization and a medical marijuana card change nothing under DOT rules. 49 CFR Part 40 still prohibits marijuana use, an MM card is not a valid medical explanation, and pending Schedule III rescheduling does not alter your testing obligations — don't change your program until final federal guidance issues.
A positive test doesn't have to end employment — but non-compliance is expensive. A driver may perform non-safety-sensitive work, and an RTD test can double as a new employer's pre-employment test (never the reverse). Knowingly letting a prohibited driver operate can cost up to $23,647 per violation, so policy, supervisor training, and program review are your cheapest protection.
