Applicable Regulations - Fort Smith, AR
Fort Smith's dominant employer base is heavily FMCSA-regulated. ArcBest and its carrier subsidiaries operate under 49 CFR Part 382. All motor carriers on I-40 and I-49 follow 49 CFR Part 382 and 49 CFR Part 40. Arkansas River port employers with USCG-regulated vessel personnel follow 46 CFR Part 16. Manufacturing employers at Whirlpool and Fort Chaffee are non-DOT for production workers but most maintain drug testing programs driven by OSHA general industry standards, customer contract requirements, and insurance obligations. Arkansas medical marijuana (Amendment 98, A.C.A. Section 20-56-408) does not require employers to accommodate cannabis use - employer drug-free workplace policies are explicitly protected. DOT testing is unaffected by the Arkansas medical marijuana program. Program design remains the employer's responsibility.

Questions from employers in this region
We are a motor carrier operating out of Fort Smith on I-40 and I-49 - can you come to our terminal for DOT random and post-accident 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, call us immediately after the scene is safe - Part 382 timing windows under 49 CFR Part 382.303 are fixed and short.
We manufacture appliances at a Fort Smith plant with large shift workforces - can you handle random pool collections without pulling workers off the production line?
Yes. At booking, share your shift schedule, pool size, and the number of donors required for the draw. We coordinate the collection window around your line rotation and shift transitions to minimize production impact.
We operate barge tows on the Arkansas River out of Fort Smith - what testing applies to our crew?
USCG regulations under 46 CFR Part 16 apply to crewmembers on inspected commercial vessels and certain uninspected commercial towing vessels operating on inland waterways. Required testing includes pre-employment, random, post-incident, reasonable cause, and return-to-duty testing. Consult your USCG marine inspector on your specific vessel classification and crew coverage requirements. We perform on-site collections for USCG-covered programs at your Fort Smith port facility.
