About Breathalyzer Tests

Orange County DUI Defense Attorney

In California, it is unlawful for a driver to operate a motor vehicle while with a BAC of .08% or greater. To prove that a driver is DUI, law enforcement will often administer a breathalyzer test. This will gauge the concentration of alcohol in the driver's breath. If it shows a result of .08% or greater, the driver will be charged with DUI.

Were you arrested for DUI? Did you submit to a breathalyzer test or refuse this test? At the Law Offices of Virginia L. Landry, we offer competent legal counsel to clients throughout all of Orange County, California who have been pulled over and arrested for DUI and who failed or refused breathalyzer tests. In these cases, you are at risk of facing driver's license suspension and criminal charges. We offer you the attorney representation you need at both your DMV hearing and in criminal court in order to seek the best possible result on your behalf.

Challenging Breathalyzer Tests

Breathalyzer tests are notoriously prone to operator error or other issues that will affect their ability to give accurate readings. For example, a breathalyzer device must be properly calibrated and maintained as per state standards. If a law enforcement agency is negligent in maintaining a breathalyzer machine, this may be grounds to bring a breath test result into question. Additional factors may also be challenged, such as whether the officer administered the test properly or was trained in doing so. By evaluating and investigating your particular case, Orange County DUI lawyer Virginia Landry can determine how to challenge your breathalyzer test.

Breath Test Refusals in California

Under California's Implied Consent law, a driver arrested for DUI in Orange County must submit to a breath test or blood test. A refusal of a chemical test will result in the automatic suspension of your driver's license.
