While the technology behind a breathalizer is complex, it basically works by analyzing the amount of alcohol present in your breath. It interprets the reading in terms of alcohol percentage. If the reading indicates the amount of alcohol in your system exceeds your state's limit, you can be arrested on the spot. The officer will ask you to blow into the small device so your reading can be taken.
A breathalizer test is often performed on a driver after law enforcement suspects a case of drunk driving. These DUI and DWI tests are considered as chemical tests, along with urine and blood tests. Field sobriety tests, such as touching your nose or walking a straight line, are often used in conjunction with a breath test or other type of chemical test.
Personal use breathalizers are also available; however, these models tend to be more inaccurate than those used by law enforcement.
If you're asked to perform a breath test, you might want to consult with a DUI lawyer first, who can advise you of your rights (the arresting police officer is required to do this, too) and help you understand the applicable DUI laws and penalties in your state.
