DOT Breath Alcohol Test

The Department of Transportation (DOT) in the United States has specific regulations and guidelines for alcohol testing, including breath alcohol testing, to ensure the safety of individuals in safety-sensitive positions, such as commercial drivers. The regulations are outlined in 49 CFR Part 40.

For breath alcohol testing under DOT regulations:

1. Approved Devices: Only devices approved by the National Highway Traffic Safety Administration (NHTSA) for evidential breath testing can be used for DOT alcohol testing. These devices must conform to the specifications outlined in the model specifications of the NHTSA.

2. Testing Procedures: Certified Breath Alcohol Technicians (BAT) or Screening Test Technicians (STT) perform the actual testing. Testing is conducted in a controlled environment to prevent interference or contamination.

3. Threshold Levels: The DOT sets the threshold for alcohol concentration at 0.02. If a driver's breath alcohol concentration is at or above this level, it is considered a positive test result.

4. Consequences of Positive Test: If a DOT-regulated employee has a confirmed positive alcohol test result, there are consequences, including removal from safety-sensitive duties, completion of the return-to-duty process, and follow-up testing.

5. Documentation and Recordkeeping: Proper documentation is crucial for compliance. Records must be kept, and specific procedures must be followed to maintain the integrity and validity of the test results.

It's important to note that these regulations may be subject to updates or changes, so it's recommended to check the latest version of 49 CFR Part 40 for the most current information. Additionally, employers and service agents involved in alcohol testing must adhere to DOT regulations to maintain compliance.
