RN Mobile Drug Testing provides DOT breath alcohol testing in Jefferson City, Missouri, using certified evidential breath testing equipment and trained breath alcohol technicians. We perform testing at our Jefferson City office or on-site at your facility — including after-hours service from 5pm to 9am.

DOT Alcohol Testing Rules

DOT alcohol testing follows the procedures in 49 CFR Part 40, Subpart J. Testing must be performed by a trained breath alcohol technician (BAT) or screening test technician (STT) using an approved device from the NHTSA Conforming Products List. Our technicians are trained in these procedures, and every test is documented on the federal Alcohol Testing Form.

When Testing Is Required

DOT regulations require alcohol testing for safety-sensitive employees in these situations:

  • Post-accident – after qualifying accidents, within 2 hours (attempts continue up to 8 hours)
  • Random – unannounced testing at the minimum annual rate for your agency
  • Reasonable suspicion – when a trained supervisor observes signs of alcohol misuse
  • Return-to-duty – after a violation, before resuming safety-sensitive duties
  • Follow-up – as directed by the Substance Abuse Professional (SAP)

Our Equipment

We use only DOT-approved evidential breath testing devices: the Intoximeter RBT-IV and the Alco-Sensor IV. Both appear on the NHTSA Conforming Products List and are calibrated and maintained to manufacturer specifications, so your results are accurate and defensible.

Trained Technicians

Our breath alcohol technicians are trained in DOT collection procedures, device operation, and Alcohol Testing Form documentation. You can expect a professional, efficient test — a screening test takes just a few minutes, and any needed confirmation test is performed after the required 15-minute wait.

Mobile Service

We bring DOT breath alcohol testing to your site anywhere in Mid-Missouri, including Jefferson City, Columbia, Fulton, California, Holts Summit, and Ashland. Mobile service is ideal for post-accident and reasonable suspicion situations, where time matters — and after-hours testing is available from 5pm to 9am.

Frequently Asked Questions

When is DOT alcohol testing required?
