Alabama DUI Test

Breath Test/Breathalyzers

If you are stopped in Alabama, on suspicion of DUI you may be asked to take a breath test at the roadside. (Note that officers must have reasonable suspicion, or probable cause to make a DUI stop.)

A breath test measures the concentration of alcohol in your breath to estimate your BAC. Breath tests are conducted at the roadside before an arrest for DUI and is called a Preliminary Alcohol Screening (PAS) test. The purpose of the PAS test is to help officers decide if there is probable cause to arrest you for DUI in Alabama. A breath test can be used as presumptive evidence in your trial for DUI.

To take the test you will be asked to blow into a portable breath analyzer (or “breathalyzer”) which will measure your blood alcohol content (BAC). In California and all other states it is a crime to drive with a blood alcohol concentration of 0.08 percent or higher. If the roadside breath test (PAS test) shows you to have a BAC at or above 0.08 you will certainly be arrested.

Should you refuse a Alabama DUI breath test (PAS test)? Yes, absolutely.

It is in your interests to exercise your right to refuse a roadside breath test:

  • The roadside is not an ideal environment for conducting a breathalyzer or any other kind of test.
  • Officers may (and often do) lack experience operating breath analyzers
  • Breath analyzers themselves are unreliable and are calibrated to calculate blood alcohol content for an “average” person.

To refute your breath test result in a DUI defense, an Alabama DUI lawyer can attempt to show that the person facing the DUI charge is not the average person and standard formulas for conversion from breath alcohol concentration to BAC don't apply.

Evidence can be introduced that shows the suspect has recently been exposed to chemical compounds containing alcohol that increased breath alcohol concentration without raising blood alcohol content. It's also possible to try to show that the breath sample was not handled correctly or the breathalyzer was not functioning properly.
