DOT-COMPLIANT · ON-SITE EMPLOYER DRUG TESTING
Texarkana, AR Mobile Drug & Alcohol Testing
I-30 Texas-Arkansas border freight corridor · Red River Army Depot contractor employers · Manufacturing and industrial workforce · St. Michael's and healthcare employers · Same-day dispatch available
Texarkana is uniquely positioned as a city that literally sits on two state lines - the Arkansas side (Miller County) and the Texas side share a downtown, a post office with two addresses, and an economy that functions as one. I-30 is the primary freight artery connecting Dallas-Fort Worth to Little Rock, Memphis, and the rest of the mid-South, and the Texarkana crossing is a significant volume point for motor carriers running this corridor. Red River Army Depot in nearby New Boston, Texas, supports a defense contractor community that extends into the Arkansas side of the metro with logistics, IT, and base support employers. Timber and paper products manufacturing has a historical base in Miller County. St. Michael's Health System anchors healthcare employer demand in the Arkansas Texarkana market. The cross-state nature of the metro means employers on the Arkansas side regularly deal with employees who live in Texas - and vice versa. OnSite Employer Testing dispatches mobile collectors to Texarkana fleet yards, defense contractor facilities, manufacturing plants, and employer sites throughout Miller County.
OnSite Employer Testing coordinates mobile drug testing collections at your Texarkana-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.
Texarkana straddles the Arkansas-Texas state line on I-30 - a critical border freight crossing and defense contractor hub where DOT fleet testing and federal drug-free workplace obligations converge at the edge of two states.

Applicable Regulations - Texarkana, AR
DOT-regulated employers in Texarkana, AR are primarily subject to 49 CFR Part 382 (FMCSA - motor carriers on I-30 and US-82) and 49 CFR Part 40. Defense contractors with federal contracts are subject to the Drug-Free Workplace Act (41 U.S.C. Section 8102) and 48 CFR Part 223. The cross-state nature of the Texarkana metro creates a specific compliance note: Arkansas law governs employees working on the Arkansas side of the line regardless of which state they reside in. Arkansas medical marijuana (Amendment 98, A.C.A. Section 20-56-408) applies on the Arkansas side and explicitly protects employer drug-free workplace policies. Texas has no medical marijuana law of significance - the Texas Compassionate Use Program is extremely limited. DOT testing is unaffected by either state's cannabis statutes. Program design remains the employer's responsibility.

Questions from employers in this region
We run a carrier fleet on I-30 between Texarkana and Dallas - can you dispatch to our Arkansas-side terminal for DOT random collections?
Yes. Provide your terminal address, CDL driver pool size, and preferred window at booking. We confirm routing and collector availability before you finalize the draw. For post-accident dispatch on I-30, call immediately after the scene is safe.
We are a defense contractor supporting Red River Army Depot operations in the Texarkana area - what testing program do we need?
Federal contracts above $100,000 require a written drug-free workplace policy under the Drug-Free Workplace Act. Red River Army Depot installation access requirements may impose additional conditions. We perform on-site collections at your Miller County or Bowie County facility for any program your contract requires. Consult your contracting officer on specific installation requirements.
Our employees live in Texas but work at our Arkansas facility - whose drug laws apply?
Arkansas law governs your Arkansas workplace regardless of where your employees reside. Your written policy applies to all employees at your Miller County facility. Texas cannabis law (which is extremely restrictive) and Arkansas cannabis law both point in the same employer-favorable direction - neither creates a cannabis accommodation obligation for your employees. DOT testing is federal and applies regardless of state.
