If you’re pulled over and suspected of drunk driving, the police officer who pulled you over may ask you to submit to a chemical sobriety test to measure your blood alcohol content, or BAC. Depending on the state where you live, you may be asked to perform one of the following BAC chemical tests:
This method is commonly referred to as a breathalyzer test, where the device measures your BAC by estimating the amount of alcohol on your breath and converting that figure to an approximate BAC.
The officer draws a blood sample to directly measure your BAC.
This method measures the amount of alcohol in your urine to determine your BAC.
Having an officer ask you to submit to chemical testing can provoke anxiety. You might not feel intoxicated, but what if the test shows your BAC is over the legal limit? Or what if you know you’re sober and think you don’t need to take the test?
