DOT-COMPLIANT · ON-SITE EMPLOYER DRUG TESTING
Employer Drug Testing Across Connecticut
We come to your Connecticut worksite, shipyard, airport operation, plant, facility, fleet yard, or jobsite. Or your employees can use any of our 8,500+ collection locations nationwide. DOT and non-DOT programs for defense, aerospace, manufacturing, healthcare, logistics, construction, and contractor employers.
Connecticut is one of the country's most concentrated markets for defense, naval shipbuilding, aerospace, advanced manufacturing, aviation, biotech, healthcare, and interstate logistics. Electric Boat in Groton, Pratt and Whitney in East Hartford, Sikorsky in Stratford, Bradley Airport-area aviation employers, and I-95/I-84/I-91 fleets create high-value compliance demand across the state.
Connecticut cannabis employment rules require more care than a standard one-size-fits-all policy. Federal DOT, DoD, FAA, USCG, and security-sensitive positions remain subject to federal or contract-specific requirements. For non-regulated roles, employers should align testing with their written policy and applicable Connecticut law. OnSite Employer Testing coordinates on-site collection and nationwide access for programs designed by your HR, legal, and compliance team.

Two Ways to Test
Every Connecticut employer program supports both collection options:
- We Come to You — A qualified collector travels to your workplace, shipyard, manufacturing floor, airport operation, fleet yard, construction site, warehouse, or facility. Ideal for groups, remote projects, new-hire cohorts, post-accident events, and safety-sensitive operations.
- 8,500+ Nationwide Locations — Employees can complete a collection at a nearby partner location anywhere in the United States. Ideal for individual hires, multi-state contractors, traveling technicians, remote workers, and interstate fleets.

Questions from employers in this region
How does Connecticut cannabis law affect employer drug testing?
Adult-use cannabis is legal in Connecticut, and the state has specific rules that may limit pre-employment cannabis testing or adverse action for some non-regulated roles unless an exception or compliant policy applies. Federal DOT, DoD, FAA, USCG, security-sensitive, and federally regulated positions can be governed by federal requirements instead. Employers should consult Connecticut employment counsel for role-specific cannabis policy decisions; we coordinate the collection program you establish.
Do you only offer on-site testing in Connecticut, or also clinic/location access?
Both. A qualified collector can travel to your Connecticut worksite, shipyard, airport operation, or facility, or employees can complete a collection at any of 8,500+ partner locations nationwide under the same employer program.
