Your DUI tests may have been administered improperly.

DUI Tests - 15 Minute Observation Period for DUI

If you are pulled over for DUI in California, you will likely be asked to take a blood or breath test. A blood or breath test is required if you are actually placed under arrest for DUI. So, if your breath test results show that you over the legal limit of .08% blood-alcohol content, that means you're guilty of DUI, right? Not necessarily.

An experienced DUI attorney may be able to prove that the DUI breath test you took was administered improperly, and this could lead to the charges against you being reduced or dropped entirely. One way to show that a breath test may have been administered improperly is to attack the required 15-minute observation period.

What is the 15-Minute Observation Period for a Breath Test?

California law requires that an officer administering a DUI breath test must continuously observe a DUI suspect for a minimum of 15 minutes. The 15 minutes must be uninterrupted and observed before administering a Breathalyzer test.

If the arresting officer did not observe you for a minimum of 15 uninterrupted minutes prior to giving you a breath test, your Wallin & Klarich DUI defense attorney can attack the blood test results as illegally obtained and inadmissible as evidence. This will also lower the credibility of the arresting officer.

Some other common things that may occur during the 15-minute period that could impact your BAC test results include:

  • You burped or belched
  • You vomited
  • You consumed alcohol or any other substance during the mandatory 15 minute observation period
  • The arresting officer was distracted by radio dispatch, taking notes, directing traffic, dealing with other people who were in the car, etc.
