D.O.T. Breath Alcohol Testing

DOT breath alcohol testing is typically performed during a DOT random drug and alcohol program. Many times breath alcohol testing is performed as a part of DOT pre employment qualifications. The majority of the time breath alcohol testing is requested as a result of a DOT post accident requirement. Other reasons for performing a breathalyzer test are “for cause”, reasonable suspicion or follow up testing. Regardless of the reason, Fas-Tes® Drug Testing is ready to offer DOT breath alcohol testing immediately to accommodate this sometimes very time sensitive service need.

Fas-Tes® performs D.O.T. evidentiary breath alcohol testing with Lifeloc Phoenix® 6.0 Portable Breath Alcohol Testing Equipment. We chose to use this equipment because Lifeloc is a leader in breath alcohol testing equipment as well as BAT Breath Alcohol Technician training. We use this equiment because it is a small digital breathalyzer with a thermal printer, which allows us to be portable for on-site testing.

Fas-Tes® uses a professional method to successfully train our BAT’s in accordance with 49 CFR Part 40 of the U.S. Department of Transportation’s Alcohol Testing Procedures.


We enjoy performing breath alcohol testing with this equipment because it has:

  • DOT and NHTSA approval
  • Software for DOT testing protocols
  • Thermal PermAffix Labels for wireless printing
  • Automatic Altitude Adjustment Compensation
  • Automatic features for error free testing

Using a breath alcohol screening test for identifying if an individual has blood alcohol concentrations greater than 0.02% is a D.O.T. approved screening test. Keep in mind that if a positive result of 0.02% blood alcohol concentration or greater is the result then a confirmation test must be administered after 15 minutes.  For a positive alcohol confirmation a breath alcohol test or breathalyzer must be utilized in accordance with DOT regulations.
