Which Employers & Employees Are Covered Under DOT Alcohol Testing Rules

Federal law under 49 CFR Part 40 requires employers in six safety-sensitive sectors to maintain alcohol testing programs for covered employees: FAA, FRA, FMCSA, PHMSA, FTA, and USCG. If your workforce includes CDL-holding drivers, pilots, transit operators, pipeline workers, railroad employees, or maritime personnel, your employees are likely subject to these requirements.

Testing occasions that trigger a DOT breath alcohol test include pre-employment, random selection, post-accident, reasonable suspicion, return-to-duty, and follow-up testing. Each occasion has specific procedural requirements under Part 40. An evidential breath testing device (EBT) must be NHTSA-approved and operated only by a certified breath alcohol technician. FastestLabs meets both requirements.

Frequently Asked Questions

What Is the DOT Alcohol Concentration Limit?

Under 49 CFR Part 40, a BAC result of 0.04 or higher constitutes a violation for safety-sensitive employees. A result between 0.02 and 0.039 requires the employee to be removed from safety-sensitive duties for a minimum period even though it doesn’t trigger a full violation.

How Is a DOT Test Different from a Standard Breathalyzer?

A DOT breath alcohol test must use an NHTSA-approved evidential breath testing device, be conducted by a certified breath alcohol technician, and follow strict chain-of-custody procedures under 49 CFR Part 40. A standard roadside breathalyzer doesn’t meet those requirements for workplace compliance purposes.

Is Mobile or On-Site DOT Breath Alcohol Testing Available?

In addition to in-lab testing, mobile and on-site testing options may be available. Contact us at (208) 408-8197 to discuss what works best for your location and scheduling needs.

What Happens After a Positive DOT Breath Alcohol Result?

The employer must immediately remove the employee from safety-sensitive duties. Return-to-duty and follow-up testing requirements under Part 40 then apply before the employee can resume those duties.

What to Expect During a DOT Breath Alcohol Test at FastestLabs

A DOT breath alcohol test follows a two-step process. The technician first administers a screening test using the Lifeloc Phoenix® 6.0. If the result is 0.02 or higher, a confirmation test is required on the EBT at least 15 minutes after the screening. Breath alcohol testing measures blood alcohol concentration (BAC) through the alcohol present in exhaled breath.

Each test uses individually-wrapped mouth blow tubes and is documented on the three-part breath alcohol testing form required under federal regulations. The technician records the result and provides copies to both the employee and the employer’s designated representative. Results are available within about 2 minutes. The entire process is designed to be straightforward, fast, and fully compliant with 49 CFR Part 40 from start to finish.
