DOT-COMPLIANT · ON-SITE EMPLOYER DRUG TESTING
Ardmore, OK Mobile Drug & Alcohol Testing
I-35 Oklahoma-Texas border freight corridor · Oil & gas and oilfield services employers · Ardmore Industrial Airpark employers · Manufacturing and industrial workforce · Same-day dispatch available
Ardmore sits approximately 100 miles south of Oklahoma City on I-35, the last significant population and commercial center before the Red River crossing into Texas. That position makes it a natural break point for long-haul motor carriers running the NAFTA corridor and a supply base for oil and gas operations in the Ardmore Basin and surrounding Carter County fields. The Ardmore Industrial Airpark is a hub for aviation manufacturing, light industrial, and aerospace supply chain operations that generate consistent employer testing demand. Oil field service companies, pipeline contractors, and energy support employers use Ardmore as a southern Oklahoma base. Hardy Murphy Coliseum and the Lake Murray corridor support a tourism and hospitality sector as well. OnSite Employer Testing dispatches mobile collectors to Ardmore fleet yards, oilfield staging areas, industrial airpark facilities, and employer sites throughout Carter County.
OnSite Employer Testing coordinates mobile drug testing collections at your Ardmore-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.
Ardmore is Oklahoma's last major commercial city on I-35 before the Texas border - a critical freight stop and oil & gas services hub in Carter County where DOT fleet testing and energy employer demand intersects daily.

DOT-regulated employers in Ardmore are primarily subject to 49 CFR Part 382 (FMCSA - motor carriers on I-35 and US-70) and 49 CFR Part 40. Pipeline operators in Carter County and the Ardmore Basin follow 49 CFR Part 199 (PHMSA) for covered pipeline systems. Aviation manufacturing and maintenance employers at Ardmore Industrial Airpark performing safety-sensitive functions on civil aircraft follow 14 CFR Part 120 (FAA). Oklahoma's OMMA program does not override DOT, PHMSA, or FAA testing requirements. Under 63 O.S. Section 425, Oklahoma employers may enforce drug-free workplace policies against OMMA cardholders. Employers near the Texas border should note that Texas has no recreational or medical cannabis law - Texas employer policy does not create any obligation on Oklahoma employers. Program design remains the employer's responsibility.

Questions from employers in this region
We are a long-haul carrier running I-35 from Dallas to OKC and we need a post-accident collection in Ardmore - can you dispatch quickly?
Contact us immediately after the scene is confirmed safe. We verify collector routing and availability to your Ardmore or Carter County location. DOT post-accident timing under 49 CFR Part 382.303 requires alcohol testing within 8 hours and drug testing within 32 hours. Do not delay. We are direct about what timing and routing is realistic for your specific location.
We have an aviation parts manufacturing operation at Ardmore Industrial Airpark - does FAA drug testing apply to us?
FAA drug and alcohol testing under 14 CFR Part 120 applies to employees performing safety-sensitive maintenance functions on civil aircraft. If your operations at Ardmore Industrial Airpark involve maintaining or repairing certificated civil aircraft, those employees are likely covered. Manufacturing of aircraft parts alone - without performing maintenance on certificated aircraft - generally falls outside FAA Part 120 scope but may be addressed by your company policy or customer quality requirements. Consult your aviation legal counsel.
We service oil wells in Carter County and our drivers cross into Texas - do Texas drug testing rules apply to our drivers?
Your CDL drivers operating qualifying CMVs are subject to FMCSA 49 CFR Part 382 regardless of which state they are in on any given day. FMCSA is a federal program and applies nationally. The state you are driving through does not change your testing obligations - your DOT program is determined by your company's FMCSA registration and the vehicles and drivers you operate.
