DOT Alcohol Testing in Memphis

DOT Breath Testing Equipment & Technician Requirements

49 CFR Part 40 establishes federal procedures for workplace drug and alcohol testing in transportation industries. Employers must also follow the requirements of the Department of Transportation agency that governs their operations.

Our certified breath alcohol technicians are trained to administer and document the applicable procedures. We use an evidential breath testing device to measure breath alcohol concentration and produce the records required for DOT testing.

For confirmation testing, the device must appear on the National Highway Traffic Safety Administration approved device list. It must also meet federal requirements for air-blank checks, result printing, device identification, and calibration records. The testing process generally includes identity and documentation checks, an initial screening test, and a confirmation test when the screening result reaches the applicable threshold.

When Employers Must Coordinate DOT Alcohol Tests

Testing obligations depend on the governing agency and the employee’s safety-sensitive duties. Pre-employment screening isn’t a universal DOT alcohol testing requirement, so employers should confirm which rules apply to their program.

Common DOT testing circumstances include:

• Random alcohol testing: Employees are selected through a scientifically valid method and tested according to applicable agency rules.
• Post-accident DOT alcohol testing: Testing may be required after an accident that meets the governing agency’s criteria.
• Reasonable-suspicion testing: An authorized supervisor initiates testing based on specific, contemporaneous observations.
• Return-to-duty testing: Testing occurs as part of the required process before an employee resumes safety-sensitive work.
• Follow-up testing: Additional unannounced tests are completed according to the established follow-up plan.

How to Prepare Before & After Testing

Clear internal procedures allow designated employer representatives to act promptly. Before scheduling, be ready to provide the testing reason, applicable DOT agency, employee information, and the name of the person authorized to receive documentation.

We can assist with creating and implementing a DOT drug and alcohol testing program, managing ongoing testing needs, and reporting test results. For mobile workplace collection, we’ll coordinate participants, paperwork, timing, and an appropriate worksite testing area.
