Los Angeles BAC (Blood Alcohol Concentration) Testing

Attorney for Los Angeles DUI Charges

A primary way for law enforcement in Los Angeles to gather evidence that a driver is “under the influence” is by testing his or her blood alcohol concentration. One’s blood alcohol concentration, or BAC, can be said to be the amount of alcohol in a person’s blood. It is typically expressed as a fractional percentage in terms of the volume of alcohol per volume of blood in the body. In California and throughout the United States, a driver may not lawfully operate a motor vehicle while with a BAC of .08% or greater. This percentage is lower for commercial drivers (.04%) or drivers under the age of 21 (.01%).

To test a driver’s blood alcohol concentration, law enforcement will request that the driver submit to a breath test or blood test. Breath tests are most commonly administered. If the driver shows a result that is above the legal limit, he or she will likely face DUI charges.

So, you were arrested for suspected DUI and took a breath test that showed an illegal blood alcohol concentration. You may feel that you have no chance of avoiding a conviction in this situation. It is important to remember that there is hope! A Los Angeles DUI attorney can take an aggressive approach to challenging the chemical tests that showed you had an illegal BAC. There are actually various ways to bring test results into question.

Challenging Chemical Testing for DUI

Any chemical test used to determine a driver’s blood alcohol concentration may be subject to any one or more of three primary issues:

  • The driver’s unique physiology;
  • The environment; and
  • Procedural errors.

Your lawyer may be able to use these issues to challenge the validity of your blood alcohol concentration testing. To find out more about how we can help with your particular case, contact Los Angeles DUI Defense Lawyer Loren M. Merlin today.
