Vehicle Code Section 23152

In California, DUI charges are normally limited to application of Vehicle Code sections 23152(a) and (b). What can be quite confusing to people charged with DUI is that often they will be charged with both subsection (a) and (b). Too many people, this creates the mistaken belief that they have been charged with two separate DUI offenses.
What most people don’t realize is that it is possible to be charged with, and even convicted of, DUI even if one’s blood alcohol content (BAC) is below 0.08 percent.

If you’ve been arrested for DUI and have not given a blood, breath, or urine sample (for whatever reason), you will most likely be charged with only section 23152(a).

If you have been arrested for DUI and have provided a blood, breath, or urine sample that shows a BAC of 0.08 percent or more, you will most likely be charged with both subsections (a) and (b) of Vehicle Code section 23152. The fact that you have been charged with both sections does not mean that you are charged with two separate
DUI offenses.

In addition to the criminal penalties that DUI convictions carry, there are administrative penalties as well with the Department of Motor Vehicles. DUI arrests require quick action on the part of the person arrested in order to protect your rights. Contact an experienced criminal defense attorney and the DMV immediately.


Vehicle Code section 23152

(a) It is unlawful for any person who is under the influence of any alcoholic beverage or drug, or under the combined influence of any alcoholic beverage and drug, to drive a vehicle.
(b) It is unlawful for any person who has 0.08 percent or more, by weight, of alcohol in his or her blood to drive a vehicle.
For purposes of this article and Section 34501.16, percent, by weight, of alcohol in a person’s blood is based upon grams of alcohol per 100 milliliters of blood or grams of alcohol per 210 liters of breath. In any prosecution under this subdivision, it is a rebuttable presumption that the person had 0.08 percent or more, by weight, of alcohol in his or her blood at the time of driving the vehicle if the person had 0.08 percent or more, by weight, of alcohol in his or her blood at the time of the performance of a chemical test within three hours after the driving.
