DOT-COMPLIANT · ON-SITE EMPLOYER DRUG TESTING
Mobile Employer Drug Testing in Columbus, Indiana
We travel to your facility — Cummins logistics center, manufacturing plant, industrial park, or fleet yard — and administer federally compliant DOT and Non-DOT collections on-site. No clinic. No downtime.
Columbus sits on I-65 in south central Indiana, with direct access to I-70, I-74, I-465, I-69, and I-64 within a two-hour drive — making it one of Indiana's best-positioned industrial cities for overnight freight to major Midwest and Southeast markets. Cummins, headquartered in Columbus, operates multiple manufacturing and logistics facilities in Bartholomew County including its Southern Indiana Logistics Center, placing a significant FMCSA-regulated CDL workforce and warehousing operation at the center of the local employer landscape. Toyota Material Handling, NTN Driveshafts, and Forvia/Faurecia add major manufacturing and industrial logistics demand. Columbus Municipal Airport and the Columbus AirPark host aviation-related tenants. The Louisville and Indiana Railroad provides short-line rail service to Columbus-area industrial parks. Columbus is within overnight shipping range of the Indianapolis International Airport FedEx hub, the UPS Worldport in Louisville, and the DHL hub at Cincinnati/Northern Kentucky — a logistics reality that creates unusual employer demand for keeping safety-sensitive rosters fully staffed and compliant around the clock.
OnSite Employer Testing coordinates mobile drug testing collections at your Columbus-area facility, logistics center, or job site. We do not operate a clinic. Review how it works or browse all locations we serve.
Why Columbus Employers Need Mobile Testing
Columbus employers operate in one of Indiana's tightest logistics windows. Cummins' Southern Indiana Logistics Center ships aftermarket parts with late-cutoff overnight delivery to dealers and distributors who need product before their service bays open in the morning. A CDL driver or warehouse associate who misses a shift because of a clinic routing delays a load that cannot be recovered. The math on mobile testing — one visit to the facility versus one employee off the clock for 90 minutes — is straightforward.
The L&I Railroad's short-line service to Columbus-area industrial parks creates FRA-regulated covered employees on properties that are primarily manufacturing-focused. Employers often overlook FRA testing obligations for rail car movers and industrial switching employees who may meet the definition of covered railroad employees. We coordinate DOT collections for rail-served industrial park tenants alongside their standard FMCSA and Non-DOT programs.
Program design and compliance obligations remain your responsibility under applicable law — we coordinate the collections.
Industries We Serve in Columbus
Diesel Engines, Logistics, and Cummins Operations
Cummins Inc. is headquartered in Columbus and operates manufacturing plants and its Southern Indiana Logistics Center in Bartholomew County. The logistics center's CDL-driving workforce — handling parts distribution for Cummins' global aftermarket network — requires FMCSA 49 CFR Part 382 pre-employment, random, and post-accident testing. Cummins' manufacturing plants employ forklift operators and CDL yard drivers subject to company-policy Non-DOT programs for pre-employment and random testing. We coordinate both DOT drug testing and Non-DOT workplace drug testing at Cummins-affiliated facilities in the Columbus area.
Manufacturing and Industrial Supply Chain
Toyota Material Handling manufactures forklifts and material handling equipment in Columbus, operating large production and logistics facilities with CDL-heavy outbound shipping. NTN Driveshafts and Forvia/Faurecia add precision manufacturing and automotive-component supply chain operations. The manufacturing corridor along I-65 and Park 65 at Woodside generates daily CDL driver and Non-DOT workforce testing demand. We coordinate collections at manufacturing campuses, distribution docks, and industrial park facilities throughout Bartholomew County.
Rail-Served Industrial Parks
The Louisville and Indiana Railroad provides short-line freight service to Columbus-area industrial parks. Rail-served tenants — manufacturers and distributors receiving inbound materials by rail car — may employ industrial switching locomotive operators or contract rail car movers who meet the FRA definition of covered railroad employees. FRA 49 CFR Part 219 random and post-accident testing obligations apply to those employees regardless of the employer's primary industry classification. We coordinate FRA-compliant DOT drug testing collections at rail-served industrial facilities in the Columbus area.
Aviation and AirPark Tenants
Columbus Municipal Airport and the Columbus AirPark host aviation-related tenants and business aviation operations. FAA 14 CFR Part 120 applies to air carriers, operators, and contractors with safety-sensitive employees at the airport. We coordinate FAA-compliant aviation and airline employer collections at the airport campus and at employer facilities in the AirPark industrial zone.
Construction and Contractor Workforce
Columbus and the I-65 corridor generate active construction project demand — infrastructure, industrial, and commercial — with general contractors and subcontractors whose CDL operators and equipment operators require DOT or Non-DOT testing as a condition of site access or company policy. We coordinate mobile collections at job site trailers and contractor staging yards throughout Bartholomew County and surrounding areas.

Questions from employers in this region
Cummins' Southern Indiana Logistics Center ships aftermarket parts on tight overnight delivery schedules. How does mobile testing fit around late-shift dispatch?
We coordinate collections at the employer's facility at a time that fits the dispatch schedule — before first departure, between shifts, or during a designated collection window your safety coordinator defines. Drivers do not leave the campus. For random selections, we work with your DER to schedule the collection at the optimal point in the operational day.
Does the Louisville and Indiana Railroad's short-line service to Columbus industrial parks create FRA testing obligations for plant employees who operate industrial switching locomotives?
Yes. Employees who perform covered service on an FRA-regulated railroad — including industrial switching operations on a short-line carrier's track — are covered railroad employees under FRA 49 CFR Part 219, regardless of whether their employer is a railroad or a manufacturer. If your plant uses L&I Railroad switching services and your employees operate locomotives during those moves, you should evaluate whether those employees meet the FRA covered-employee definition. Program design and compliance obligations remain your responsibility under applicable law — we coordinate the collections.
Toyota Material Handling ships forklifts by truck across the country from Columbus. Are their outbound CDL drivers subject to FMCSA 49 CFR Part 382?
Yes. CDL drivers operating commercial motor vehicles with a GVWR above 26,001 pounds in interstate commerce are subject to FMCSA 49 CFR Part 382 regardless of the commodity being transported. Forklift and heavy equipment shipments by flatbed or specialized carrier meet those thresholds. Pre-employment, random, and post-accident testing are all required program components.
Do you serve industrial employers in the Seymour and Edinburgh corridor south of Columbus along I-65?
Yes. The I-65 corridor from Columbus south through Edinburgh, Seymour, and into Jackson County is within our standard service range. FMCSA-regulated carriers, manufacturers, and construction employers throughout that corridor can schedule mobile collections at their facilities.
