Breath and Blood Tests

San Diego DUI Lawyer

If you were arrested for DUI after failing or refusing a breath or blood test an experienced and knowledgable San Diego DUI attorney at DUI Crew can help you.

In order to convict one for DUI (driving under the influence) in San Diego, law enforcement and the prosecuting attorney will often utilize a driver’s breath or blood test results. A breath test, blood test or sometimes a urine test may be used to determine a driver’s blood alcohol concentration (BAC). If the driver is operating a vehicle while having a blood alcohol concentration of .08% or higher, they may be charged with DUI. Underage drivers can have their license suspended with a BAC of .01% or greater, and commercial drivers can face criminal charges with a BAC of .04% or higher.

About Breath Tests and Blood Tests

A breath test is usually administered by having the driver blow into a breathalyzer device which determines the concentration of alcohol from the breath sample. Breath tests are typically considered less reliable than blood tests and may have a number of issues arise that can affect the result. A lawyer can bring these into question to challenge your breath test result in court. For example, the breathalyzer machine must be calibrated frequently and according to state standards in order for the results to be admissible in court. If the breathalyzer device was not calibrated, your attorney may be able to use this to help your case.

A blood test is administered by taking a sample of blood and then processing this to determine the driver’s blood alcohol concentration. Although blood tests are more accurate than breath tests, blood tests have their own faults as well and may be improperly handled, administered by an untrained professional or otherwise mishandled. Your attorney may be able to use this to help you win your case.

“Howard represented me for my DUI case a couple months ago. My BAC level was .22 which is pretty high but he was able to reduce my charges in court to a wet reckless. I hope I don’t get another DUI but if I do, Howard would be my first call.”  – Client 2012
