Under federal law (49 CFR Part 40), any employee in a DOT-regulated safety-sensitive position who fails or refuses a drug or alcohol test must be evaluated by a DOT Qualified Substance Abuse Professional before they can return to work. This applies to CDL truck drivers, MBTA transit workers, Amtrak railroad employees, aviation workers, pipeline workers, and maritime employees — all of whom operate in Massachusetts.
The SAP evaluation is not a punishment. It's a clinical assessment designed to determine what education or treatment, if any, is appropriate — and to establish a path back to safety-sensitive work. The SAP is the only person who can authorize a return-to-duty test.
I'm Paul Collette, MS, LADC. I'm independently licensed in Massachusetts (LADC1) and offer virtual evaluations statewide. Same-day and next-day scheduling is available.

Massachusetts CDL drivers: a positive test enters the FMCSA Clearinghouse immediately.
CDL drivers, freight carriers, owner-operators, and commercial drivers throughout Massachusetts — from the Pike to Route 128 and beyond.
Pilots, air traffic controllers, aircraft mechanics, and other safety-sensitive aviation workers at Logan International (BOS), Worcester Regional (ORH), and Hanscom Field.
Railroad workers on Massachusetts rail lines, including Amtrak, MBTA Commuter Rail, and freight operators serving the state's dense rail network.
MBTA operators, maintenance workers, and all FTA-regulated transit employees in the Greater Boston area and throughout the Massachusetts Bay Transportation Authority system.
Natural gas and hazardous liquid pipeline workers operating in Massachusetts under PHMSA jurisdiction — including Eversource and National Grid employees.
Commercial maritime workers on Massachusetts waterways, including Boston Harbor, New Bedford's working port, and Cape Cod Canal operations.
We meet virtually over a secure video call — fully compliant with 49 CFR Part 40. I review your history, the circumstances of the test, and any substance use concerns. This typically takes 1–2 hours and can be scheduled same-day.
Based on my evaluation, I recommend either an education program or a formal treatment program. This is a clinical decision — I recommend what's appropriate for your situation, not the most expensive option.
You complete the education or treatment program I've recommended. Massachusetts has strong substance use treatment resources, and I can refer you to DOT-compliant providers throughout the state.
Once you've completed the program, we meet again. I review your records, assess your current status, and determine whether you're ready to return to safety-sensitive duties.
You pass a directly observed drug and/or alcohol test arranged by your employer or C/TPA. Once you pass, you can return to your safety-sensitive position.
After returning to work, you'll be subject to unannounced follow-up testing for up to five years. I determine the number and frequency of tests as your SAP.
Paul Collette brings over two decades of clinical expertise — including 24 years in federal probation, 6 years in drug court, and 7+ years in private practice. He is independently licensed in Massachusetts (LADC1) and understands both the clinical and regulatory dimensions of DOT compliance.
