DOT-COMPLIANT · ON-SITE EMPLOYER DRUG TESTING
Mobile Employer Drug Testing in Lafayette, Indiana
We travel to your facility — trailer plant, engine manufacturing campus, fleet yard, or aerospace employer — and administer federally compliant DOT and Non-DOT collections on-site. No clinic. No downtime.
Lafayette sits on I-65 at U.S. 52 and U.S. 231 in west central Indiana, with Amtrak service and freight rail corridors running through the Wabash River valley. Wabash National — one of North America's largest manufacturers of semi-trailers and truck bodies — is headquartered in Lafayette, making the city home base for the company that builds the trailers used by FMCSA-regulated fleets across the country. Caterpillar's Large Engine Division produces diesel and natural-gas engines in Lafayette for transportation and industrial markets. GE Aviation operates an advanced manufacturing plant in the Greater Lafayette area, bringing FAA-adjacent aviation manufacturing employment to the region. Purdue Airport in West Lafayette and the Purdue Aerospace District serve aviation employers and aerospace research tenants with FAA-regulated operations. For employers in a city where the products made drive DOT regulatory demand nationally, mobile testing at the facility keeps the workforce that builds those products compliant without interrupting production.
OnSite Employer Testing coordinates mobile drug testing collections at your Lafayette-area facility, manufacturing plant, or fleet yard. We do not operate a clinic. Review how it works or browse all locations we serve.
Why Lafayette Employers Need Mobile Testing
Lafayette's manufacturing identity is built on transportation equipment and industrial power — trailers, diesel engines, and aviation components. The workforces that build those products are subject to Non-DOT company-policy testing programs and, for CDL-driving plant logistics employees, FMCSA DOT programs. Wabash National's manufacturing campus, Caterpillar's engine plant, and GE Aviation's facility all operate on production schedules where an unplanned absence for a clinic trip disrupts a shift. Mobile collection at the plant eliminates that disruption.
The Purdue Aerospace District adds FAA-regulated aviation employers to the Lafayette market — a category that competitors' generic 'drug testing in Lafayette' pages almost never address specifically. Post-accident testing for FAA safety-sensitive employees has mandatory regulatory response requirements that a clinic-based model cannot reliably meet for an employer located in an aerospace research district.
Program design and compliance obligations remain your responsibility under applicable law — we coordinate the collections.
Industries We Serve in Lafayette
Trailer and Transportation Equipment Manufacturing
Wabash National is headquartered in Lafayette and manufactures dry-van trailers, refrigerated trailers, platform trailers, and liquid tank trailers — the core equipment of the FMCSA-regulated trucking industry. The manufacturing campus employs production workers, CDL yard drivers, and outbound shipping crew subject to Non-DOT company-policy testing and, for CDL interstate operators, FMCSA 49 CFR Part 382 programs. Wabash also operates a fleet of carrier and test vehicles that may require DOT testing oversight. We coordinate both DOT drug testing and Non-DOT workplace drug testing at the Wabash campus and at supplier facilities in the Lafayette area.
Engine and Industrial Power Manufacturing
Caterpillar's Large Engine Division in Lafayette produces diesel and natural-gas engines for transportation, oil and gas, and industrial power applications. The plant employs a large shift-based manufacturing workforce with CDL-driving supply chain logistics staff moving components and finished engines. Non-DOT company-policy programs for production employees and FMCSA programs for CDL drivers are standard for an employer of this scale. We coordinate collections at the Caterpillar campus and at supplier facilities throughout Tippecanoe County.
Aviation Manufacturing and Aerospace Employers
GE Aviation operates an advanced manufacturing plant in the Greater Lafayette area producing components for commercial and military aircraft engines. FAA-adjacent aviation manufacturing employers — while not always subject to FAA Part 120 directly — often maintain Non-DOT programs aligned with aviation industry safety standards. Purdue Airport in West Lafayette and the Purdue Aerospace District host FAA-regulated aviation employers including fixed-base operators, charter carriers, and aerospace research tenants. We coordinate FAA-compliant aviation and airline employer collections at airport facilities and aerospace campus locations.
Trucking and Rail-Served Freight
I-65 and U.S. 52 generate significant logistics and transportation activity through Tippecanoe County. FMCSA-regulated carriers staging at Lafayette for the I-65 corridor serve Wabash, Caterpillar, and broader Greater Lafayette industrial base shipments. Freight rail access through the Wabash River valley corridor supports rail-served industrial tenants with FRA-regulated covered employee obligations. We coordinate FMCSA and FRA-compliant collections at carrier facilities and rail-served industrial sites.
Construction and Infrastructure
The Greater Lafayette area's active commercial, industrial, and infrastructure construction sector employs CDL operators and heavy equipment operators subject to FMCSA or Non-DOT testing programs. Construction contractors working on industrial projects at the Purdue Aerospace District, shovel-ready industrial sites, and I-65 corridor development are within our service range. We coordinate collections at job site trailers and contractor yards throughout Tippecanoe County.

Questions from employers in this region
Wabash National builds trailers for FMCSA fleets across the country. What DOT testing program applies to Wabash's own CDL yard and test-drive operators?
Wabash National employees operating CDL vehicles in interstate commerce — including outbound delivery drivers and test drivers operating on public roads — are subject to FMCSA 49 CFR Part 382. Production plant employees who do not operate commercial motor vehicles in interstate commerce are not subject to FMCSA but may be covered by a Non-DOT company-policy program. Program design and compliance obligations remain your responsibility under applicable law — we coordinate the collections.
GE Aviation's Lafayette plant makes components for aircraft engines. Are those employees subject to FAA 14 CFR Part 120?
FAA 14 CFR Part 120 applies to air carriers, operators, and contractors who perform safety-sensitive functions as defined by the FAA — typically direct aviation operations including flight crew, ground crew, fueling, and aircraft maintenance performed on certificated aircraft. Manufacturing employees who produce components but do not perform these direct operational functions at a certificated air carrier operation are generally not subject to Part 120. They may, however, be subject to Non-DOT company-policy testing or, in some cases, DOD requirements if the contract involves military aircraft. Program design and compliance obligations remain your responsibility — we coordinate the collections.
Caterpillar runs three production shifts. Can you accommodate random selections that need to happen before the 0500 first shift?
Yes. For employers with early morning shift starts, we coordinate with your Designated Employer Representative to schedule random collections at a time that fits the shift structure. Collections happen at your designated on-site location; employees do not leave the campus.
Do you serve aviation employers at Purdue Airport and in the Purdue Aerospace District in West Lafayette?
Yes. Purdue Airport and the Purdue Aerospace District in West Lafayette are within our standard Tippecanoe County service range. We coordinate FAA-compliant collections for charter carriers, FBO operators, and aerospace research tenants with safety-sensitive employees at those facilities.
