Boston, MA Mobile Drug & Alcohol Testing
Logan Airport & Port of Boston carriers · Longwood Medical employers · Seaport construction sites · I-93 / I-90 fleet operators · Same-day dispatch available
Boston's economy is built on industries where workforce compliance isn't optional: air cargo and ground transport operators serving Logan International Airport, marine and port employers at Conley Terminal, a healthcare workforce exceeding 73,000 people in the Longwood Medical and Academic Area alone, and a construction sector that added thousands of jobs in recent years along the Seaport and I-93 corridor. Add to that the city's staffing agencies, biotech manufacturing plants in Kendall Square and the Innovation District, and government contractors near South Station - and the demand for on-site, schedule-friendly drug and alcohol testing is constant. OnSite Employer Testing dispatches mobile collectors to Boston worksites, job-site trailers, fleet yards, and employer facilities so your people stay on the floor, on the dock, or on the job instead of losing a half-shift at a clinic.
OnSite Employer Testing coordinates mobile drug testing collections at your Boston-area facility, yard, terminal, or job site. We do not operate a clinic. Review how it works or browse all locations we serve across the region.
Boston anchors New England's largest concentration of safety-sensitive employers - from Logan's freight ramps to the Longwood biomedical corridor.

Applicable Regulations - Boston, MA
Employers with DOT-regulated operations in Boston fall under 49 CFR Part 40 (testing procedures), 49 CFR Part 382 (FMCSA/motor carriers), 49 CFR Part 655 (FTA - MBTA and transit contractors), 14 CFR Part 120 (FAA - Logan-based aviation employers), and 46 CFR Part 16 (USCG - marine/port operators at Conley Terminal). Massachusetts has legalized recreational cannabis under M.G.L. c. 94G; however, a positive THC result under a DOT program is still a DOT violation regardless of state law - DOT supersedes state cannabis statutes in all federally regulated testing. Non-DOT employers should review their written policy language to ensure it addresses Massachusetts' current employment and cannabis statutes. Program design, cutoff thresholds, and policy language remain the employer's responsibility.

Questions from employers in this region
Can you come directly to our job site near the Seaport or Fort Point without us arranging a clinic?
Yes. We dispatch mobile collectors to active construction sites, employer yards, and facilities throughout Boston. You provide the site address and your preferred window; we confirm collector availability and routing before you hold the calendar. No clinic visit is needed for your employees.
Massachusetts has legal recreational cannabis - does that affect our DOT-required testing program?
No. DOT drug testing operates under federal law (49 CFR Part 40), which explicitly states that state cannabis laws have no bearing on DOT program requirements. A confirmed positive for THC under a DOT test is a violation regardless of an employee's Massachusetts cannabis card or recreational use. Non-DOT programs are governed by your company policy, so we recommend reviewing that language with your legal counsel.
We have employees at multiple Boston locations and a rotating shift schedule - can you handle multi-site random collections in one dispatch?
We can schedule collections across multiple employer sites in the same dispatch window when routing allows. Tell us your site addresses, headcounts, and shift times when you request coverage, and we'll build a practical window that fits your operation rather than asking your team to travel to a single location.
