To become a qualified Breath Alcohol Technician (BAT) or Screening Test Technician (STT), you must know Part 40 and the DOT agency rules that apply to the employers you serve, and you must complete a qualification training program and a monitored proficiency demonstration (49 CFR 40.213). Your qualification is not tied to a location.
Law enforcement officers certified by a state or local government to conduct breath alcohol testing are deemed qualified as BATs.
Do I need to be "certified"?
No. DOT does not certify BATs or STTs and does not keep a registry. You only need to be qualified before conducting DOT alcohol tests.
What is the difference between an STT and a BAT?
An STT may conduct screening tests only, using an approved alcohol screening device (ASD). A BAT may conduct screening tests with an ASD or an evidential breath testing device (EBT), and confirmation tests with an EBT.
What must the training cover?
- The DOT model BAT or STT course, or an equivalent course.
- Part 40 alcohol testing procedures.
- Operation of the specific testing device you will use.
- Your responsibility to protect the integrity of the process and the employee's privacy.
The instructor must be a qualified BAT or STT who has regularly conducted DOT alcohol tests for at least one year, has taught BAT or STT courses for at least one year, or has completed a "train the trainer" course.
What is the proficiency demonstration?
After training, a BAT completes seven consecutive error-free mock tests and an STT completes five. The mock tests show that you can respond to the device's messages, handle errors and malfunctions, recognize an air blank, and know when an external calibration check is needed. The monitor must attest in writing that the mock tests were error-free.
Documentation and refresher training
- Be ready to show DOT agency inspectors, employers, and service agents that you are currently qualified.
- Complete refresher training at least every five years.
Which devices are approved?
Screening tests must use a device on the National Highway Traffic Safety Administration (NHTSA) Conforming Products List for screening devices; confirmation tests must use an EBT on the NHTSA list for evidential devices.
DOT does not offer or approve BAT or STT training. For more information, visit the DOT Office of Drug and Alcohol Policy and Compliance (ODAPC).
