Breath/Blood-Alcohol Tests

Breathalyzer/BAC Test Attorney Serving the Bay Area and Oakland

  • Were you pulled over on suspicion of drunk driving?
  • Were you administered a Breathalyzer, Intoxilyzer, or blood-alcohol test?

If you have been pulled over for drunk driving in California, chances are the police officer administered a Breathalyzer test, blood-alcohol content (BAC) test, or another test to check your sobriety. However, these tests do not always accurately check an individual's level of intoxication — but they are still used as evidence in many cases.

At the Law Office of Thomas F. McKenna, we defend people who have been charged with drunk driving. We are experienced in challenging the evidence supplied in Breathalyzer, Intoxilyzer and BAC tests.

Refusing Sobriety Tests — A Good Idea?

In California, an individual pulled over for suspicion of drunk driving is required to submit to one of two chemical tests: a breath or blood test It is never wise to refuse one of these tests: your driver's license can be suspended for one or two years, depending on your prior record.

Reliability of Breath and BAC Tests

Although the blood-alcohol test is quite reliable, the breath test is not. If you have been charged with drunk driving based on the results of a Breathalyzer test, it may be possible to challenge its accuracy.

Attorney Tom McKenna has defended thousands of individuals charged with DUI/DWI, and knows how inaccurate breath tests often are - even though these tests are often used as evidence in cases.
