DOT Breath Alcohol Test (BAT)
DOT Breath Alcohol Testing (BAT) is a federally regulated process required for safety-sensitive positions, especially those governed by the FMCSA and Department of Transportation. Edify Screening’s BAT service uses certified devices, trained technicians, and strict chain-of-custody protocols to deliver results that are fast, reliable, and fully compliant with 49 CFR Part 40.
Whether it’s part of a pre-employment screening, random test, post-accident response, or return-to-duty protocol, our DOT BAT process ensures your program remains compliant—and your workforce remains safe. Results are documented in real-time and reported securely with MRO oversight where applicable.
How It Works
- Performed using DOT-approved breath alcohol testing devices.
- Initial screening followed by confirmation test if result is ≥ 0.02.
- Administered by certified BAT technicians with documentation protocols.
When to Use It
- Required for CDL holders under FMCSA or other DOT-regulated agencies.
- Post-accident, reasonable suspicion, return-to-duty, or follow-up testing.
- Any situation where alcohol use could impair safety or compliance.
TAT & Fees
- Test results typically available within minutes.
- Includes technician labor and device certification.
- Mobile testing options available (location-based fees may apply).
Why It Matters
Alcohol use behind the wheel or during safety-sensitive work creates serious risk and federal liability. DOT BAT ensures real-time alcohol detection under strictly observed, tamper-proof conditions. For employers, this means protecting the public, staying audit-ready, and taking swift action when impairment is suspected. Every test follows the gold standard of federal compliance.
Use-Cases
- Trucking companies conducting post-accident screening.
- Transit agencies performing random testing on duty personnel.
- Return-to-duty programs verifying sobriety before reinstatement.
DOT Breath Alcohol Test FAQs
Q: What is the threshold for a failed DOT breath alcohol test?
A: A result of 0.04 or higher is considered a DOT violation. Results of 0.02 to 0.039 require removal from duty until re-tested.
Q: Is the test observed?
A: Yes. All DOT BATs are directly observed by a trained technician using certified equipment.
Q: What if the first test is positive?
A: A confirmation test is required at least 15 minutes later, using a different device or procedure.
Q: Do I need to provide consent forms?
A: Yes. DOT requires written authorization from the employee prior to any alcohol testing.
Q: How is this different from a regular breathalyzer test?
A: DOT BAT includes strict federal procedures, certified staff, and equipment—all documented to ensure defensibility.
Q: Can I combine this with a drug test?
A: Yes. Many employers run a BAT alongside DOT or non-DOT drug panels for complete screening.
