A breath alcohol test is a non-invasive and rapid method of determining the amount of alcohol in an individual's bloodstream. A breath alcohol test determines how much alcohol is in your blood by measuring the amount of alcohol in the air you breathe out (exhale). The device called a breathalyzer uses that measurement to estimate how much alcohol is present in the person’s blood, known as BAC or blood alcohol content.
While navigating through alcohol tests, the most frequently asked question is how long does alcohol stay in your system?
Depending upon the type of test, the detection window of alcohol varies between 6-72 hours, a breath alcohol test can detect alcohol for 12-24 hours after its consumption.
There is a misconception that sleeping and drinking water increases the rate of alcohol absorption in the body, which is not true. Whereas, certain factors like the quantity of alcohol consumed, metabolism, gender, and weight of a person can affect the process of alcohol inside the body.
FMCSA requires employers to conduct drug and alcohol test for the employees performing safety-sensitive work. The drivers are directed for substances and alcohol tests under specific circumstances like pre-employment (for controlled substances only), reasonable suspicion, post-accident, random, return-to-duty, and follow-up. The following are some conditions stated by FMCSA for alcohol test:
Local authorities may also suspect you of DUI (Drug Under the Influence) if you're exceeding the speed limit, causing an accident, or veering off the road. If you're pulled over by the police, they can use a Breathalyzer to check your blood alcohol content right there at the scene of the accident.
Companies performing safety-sensitive work are federally mandated by the Department of Transportation and FMCSA to perform DOT drug and alcohol tests. Drug and alcohol testing is also a common practice to be performed on drivers who are caught speeding or involved in accidents. However, it is also demanded by companies as a pre-employment test to keep the workplace safe.
