Breath Alcohol Testing

Drink Responsibly, Test Responsibly

What Is Alcohol Testing?

With the use of evidential breath testing (EBT) devices, we can measure how much alcohol is currently in the bloodstream.  The legal limit establishing impairment while driving is .08.

The Department of Transportation guidelines mandate that if an employee has a .04 positive test, then it requires the removal of the employee from driving or other safety-sensitive tasks. If it is a .02 result, under DOT regulations, then it requires the removal from tasks for a certain period.

Today, mandatory alcohol and drug testing is a requirement of the United States Department of Transportation for some occupations and industries. This mandatory testing includes trucking, aviation, maritime, pipeline, railroad, and transit employees in safety-sensitive occupations.

Alcohol consumption is completely legal, it is highly accessible, and it is socially acceptable. For these reasons, it is one of the top substances which cause a failed drug/alcohol test in the United States.

Some subjects cannot complete a BAT test because of health issues. Subjects that are heavy smokers, are asthmatic, or have other respiratory issues – may be unable to complete the test. The BAT test requires subjects to blow a steady stream of air into the EBT device. Subjects with respiratory issues will then receive a strip test or a saliva test. This will give the same results as a breath alcohol test.

Reasons An Employer May Enforce BAT Testing

Employers outside the mandate of DOT testing typically use alcohol testing under specific circumstances:

  • The employer may have a policy that requires a test when there is reasonable suspicion. This is known as probable-cause testing. The employer may also test if there are documented signs of possible alcohol or drug use by an employee.

  • Post-accident testing occurs whenever there is suspected alcohol or drug use that caused property damage. If alcohol or drug use is suspected in a personal injury situation in the workplace, post-accident testing may also occur. This is to clarify if impairment plays a role in the cause of the accident.

  • Random testing is performed on an unannounced, unscheduled basis on employees who have been selected arbitrarily from a testing pool.

Things to Know About Alcohol Testing


BODT breath alcohol technicians (BAT) only use Evidential Breath Testing (EBT) devices approved by the Department of Transportation.

Our EBT devices provide the following capabilities:

  • Printed triplicate result
  • Assigns a unique number to each completed test
  • Prints, on each copy of the result, the manufacturer’s name for the device, its serial number, and the time of the test
  • Distinguishes alcohol from acetone at the 0.02 concentration level
  • Tests an air blank; and
  • Performs an external calibration check

The BAT test and the saliva strip test provide immediate results. An ETG test may take 24-48 hours for results.

A BAT test does not measure the amount of alcohol drunk, rather it detects the alcohol levels in the body.
