DOT-COMPLIANT · ON-SITE EMPLOYER DRUG TESTING
On-Site Employer Drug Testing in Gallup, New Mexico
I-40 Southwest Corridor - BNSF Transcon Gallup Sub - McKinley County Coal and Energy - Navajo Nation Construction Contractors - Four Corners Energy Sector - US-491 Northern Corridor
Gallup is a major commercial hub on the I-40 Southwest Corridor, handling significant east-west freight traffic between Albuquerque and Flagstaff. BNSF's Transcon line -- the highest-volume freight railroad corridor in the United States -- passes through McKinley County, with Gallup serving as a key division maintenance point and FRA 49 CFR Part 219 obligations for covered rail crews. The I-40 corridor drives intense FMCSA CDL testing demand for motor carriers. McKinley County sits adjacent to the Four Corners energy region, with coal and gas operations and associated MSHA and PHMSA obligations. Navajo Nation construction and infrastructure contracting -- tribal projects on Navajo Nation lands that cover much of McKinley County -- creates demand for both tribal-compliant and federally-compliant testing programs. Construction activity driven by healthcare, commercial, and tribal infrastructure projects is a major employer sector. Our collectors reach BNSF facilities, trucking terminals, contractor yards, and construction sites across McKinley County.
OnSite Employer Testing coordinates mobile drug testing collections at your Gallup-area facility, yard, terminal, or job site. We do not operate a clinic. Review how it works, browse New Mexico locations, or see all locations we serve.

BNSF, I-40 Corridor FMCSA, and Navajo Nation Contractor Testing in McKinley County
Gallup employers on the I-40 corridor face the full weight of FMCSA and FRA testing requirements. BNSF Transcon crews and CDL drivers on I-40 are subject to federal DOT rules that supersede New Mexico's recreational cannabis law. For Navajo Nation contractors, testing programs must satisfy both federal DOT requirements and any applicable tribal contract conditions -- the Navajo Nation government increasingly requires documented drug-free workplace programs for contracts on tribal lands. New Mexico Cannabis Regulation Act Section 26-2C-30 preserves McKinley County employer rights for non-federal positions.

Questions from employers in this region
We are a general contractor on a Navajo Nation infrastructure project in McKinley County. What drug testing do we need?
At minimum, your CDL operators require a FMCSA-compliant DOT program. Navajo Nation contracts for major infrastructure work frequently include drug-free workplace provisions -- review your tribal contract terms and any NTUA or NAPI project requirements. Drug-Free Workplace Act obligations may apply if federal funding flows through the project. We provide on-site collections at your McKinley County project site and can document testing for both federal and tribal contract compliance.
We run a trucking terminal in Gallup on I-40. How do we manage random testing for drivers who are rarely at the terminal?
We coordinate random selection and collection scheduling to match your drivers' arrival windows at your Gallup terminal. When a driver is selected for random testing, we dispatch a collector to your terminal during their next available stop or layover. DOT random drug testing at 50% annually can be managed on an on-site schedule with proper planning -- call (219) 315-0345 to set up a program.
Can we include cannabis in our Gallup employee drug testing panel?
Yes. Standard 5-panel and 10-panel urine tests include THC metabolites. NMSA 1978 Section 26-2C-30 allows McKinley County employers to test for cannabis and take adverse action on positive results under a written drug-free workplace policy. For FRA and FMCSA covered employees, cannabis testing is mandatory under federal rules.
