Oklahoma City, OK Mobile Drug & Alcohol Testing
I-35 / I-40 fleet operators · Tinker AFB defense contractors · Oil & gas and pipeline employers · Aerospace & aviation maintenance workforce · Same-day dispatch available
Oklahoma City is the economic and geographic center of the Southern Plains, positioned where I-35 (the north-south NAFTA corridor from Laredo to Duluth) intersects I-40 (the east-west corridor from Los Angeles to North Carolina). That interchange alone drives enormous FMCSA-regulated fleet testing demand from motor carriers, tanker operators, and LTL distributors running both corridors. Tinker Air Force Base - the largest military installation in Oklahoma and home to the Air Force Sustainment Center - anchors a defense contractor and aerospace maintenance ecosystem employing tens of thousands. The city's oil and gas industry runs from wellhead to pipeline to refinery, with major operators and service companies headquartered downtown and operating across the Anadarko Basin. The FAA's Mike Monroney Aeronautical Center, also located in Oklahoma City, adds federal aviation employer testing obligations. Oklahoma City's construction sector has ranked among the fastest-growing in the country for multiple consecutive years. OnSite Employer Testing dispatches mobile collectors to OKC fleet yards, Tinker contractor facilities, oil field service staging areas, construction sites, and employer locations throughout Oklahoma County and the surrounding metro.
OnSite Employer Testing coordinates mobile drug testing collections at your Oklahoma City-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.
Oklahoma City sits at the I-35/I-40 crossroads of the nation's midsection - a major oil & gas, aerospace, and logistics hub where DOT and federally mandated employer testing is a daily operating requirement.

Applicable Regulations - Oklahoma City, OK
Oklahoma City's multi-industry employer base spans several DOT modal rules. Motor carriers on I-35 and I-40 follow 49 CFR Part 382 (FMCSA). Aviation maintenance employers at Tinker AFB (civil aircraft functions) and Will Rogers World Airport follow 14 CFR Part 120 (FAA). Pipeline operators carrying gas or hazardous liquids follow 49 CFR Part 199 (PHMSA). All DOT collections follow 49 CFR Part 40. Defense contractors at Tinker AFB are subject to the Drug-Free Workplace Act (41 U.S.C. Section 8102) and 48 CFR Part 223. Oklahoma does not have a recreational cannabis law; only the Oklahoma Medical Marijuana Authority (OMMA) program exists under State Question 788. Under 63 O.S. Section 425, Oklahoma employers may still enforce a drug-free workplace and deny employment or terminate employees who test positive for cannabis even with a valid OMMA license. DOT testing is unaffected by Oklahoma's medical cannabis program. Program design remains the employer's responsibility.

Questions from employers in this region
We are a Tinker AFB contractor with both DOT drivers and non-DOT facilities workers - can you handle both programs in one dispatch?
Yes. At booking, specify which employees are DOT-regulated (FMCSA, FAA, or PHMSA) and which are non-DOT so our collector arrives with the correct chain-of-custody documentation for each program. We confirm routing and availability before you hold the schedule.
Oklahoma has a medical marijuana program - can our oil field employees use OMMA cards to avoid consequences for a positive THC result?
No. For DOT-regulated employees (FMCSA, PHMSA pipeline operators), federal law controls and an OMMA card provides no protection against a DOT violation. For non-DOT employees, Oklahoma law under 63 O.S. Section 425 explicitly allows employers to enforce drug-free workplace policies and act on positive cannabis results even when an employee holds a valid OMMA license. Program consequences are the employer's responsibility.
We run a tanker fleet out of OKC on I-35 and I-40 - how quickly can you dispatch for a post-accident collection?
Contact us immediately after the incident is confirmed safe to address. DOT post-accident timing under 49 CFR Part 382.303 requires alcohol testing within 8 hours and drug testing within 32 hours of a qualifying incident. We verify collector routing and availability to your location as soon as you call. Do not delay.
