On-Site Employer Drug Testing in Miles City, Montana
BNSF Yellowstone Subdivision - I-94 Eastern Montana Corridor - Custer County Agriculture and Ranching - Cedar Creek Anticline Oilfield - Miles City Airport - Southeastern Montana Contractors
Miles City is the commercial hub of southeastern Montana, serving Custer County's ranching economy, BNSF rail operations on the Yellowstone Subdivision, and oilfield services contractors working the Cedar Creek Anticline oil and gas formation. BNSF train and engine crews and maintenance-of-way workers in Custer County are subject to FRA 49 CFR Part 219 testing requirements. The I-94 corridor through Miles City is a primary commercial freight route for eastern Montana, with FMCSA CDL testing obligations for motor carriers. Oilfield services contractors working the Cedar Creek Anticline face PHMSA pipeline testing requirements for covered roles. Agricultural employers -- livestock dealers, feed operations, farm supply distributors -- increasingly maintain testing programs for CDL drivers and safety-sensitive positions. Our collectors travel to BNSF facilities, contractor yards, and agricultural operations in Custer County directly.
OnSite Employer Testing coordinates mobile drug testing collections at your Miles City-area facility, yard, terminal, or job site. We do not operate a clinic. Review how it works, browse Montana locations, or see all locations we serve.

Eastern Montana Employer Rights and DOT Compliance in Miles City
Custer County employers retain full rights under Montana Code Ann. Section 16-12-108 to test for cannabis and enforce drug-free workplace policies. For BNSF rail crews, FMCSA CDL operators, and PHMSA pipeline personnel, federal rules govern and cannabis testing is mandatory. Agricultural CDL drivers operating commercial motor vehicles in interstate commerce -- including livestock haulers crossing into Wyoming or the Dakotas -- require FMCSA-compliant testing programs. A documented policy protects ranching and agricultural employers from negligent hiring and workers' compensation exposure in a sector with elevated injury rates.

Questions from employers in this region
We are a cattle rancher in Custer County with two CDL drivers hauling livestock interstate. Do we need a DOT drug testing program?
Yes. CDL drivers operating commercial motor vehicles -- including livestock trailers over 26,000 lbs GVWR or with air brakes -- in interstate commerce are covered by DOT FMCSA 49 CFR Part 40. Even two drivers trigger the requirement for a compliant program: pre-employment, random, post-accident, and reasonable suspicion testing. We come to your Custer County ranch or loading facility for collections -- your drivers stay on the operation.
Our Miles City oilfield services company works on both Montana and North Dakota wellpads. Which state's drug testing rules apply?
Federal DOT rules apply regardless of which state you are operating in. PHMSA pipeline operator requirements under 49 CFR Part 199 are federal and apply in both Montana and North Dakota. FMCSA CDL requirements under 49 CFR Part 40 are federal and apply in both states. For non-DOT positions, both Montana Code Ann. Section 16-12-108 and North Dakota employer rights statutes allow testing and zero-tolerance policies. We serve both states and can coordinate collections at your Montana and North Dakota worksites.
Can you set up a testing program for a Miles City employer who has never tested before?
Absolutely. We handle everything from program design to first collection. We help you identify covered positions, select the right testing panels, draft or review your written drug-free workplace policy, and schedule your first collections. For most small to mid-size Miles City employers, we can have a program active within 24 to 48 hours. Call (219) 315-0345 to get started.
