California Vehicle Code VC 23610 - Blood-Alcohol Level: Presumptions Affecting Burden of Proof.

23610. (a) Upon the trial of any criminal action, or preliminary proceeding in a criminal action, arising out of acts alleged to have been committed by any person while driving a vehicle while under the influence of an alcoholic beverage in violation of subdivision (a) of Section 23152 or subdivision (a) of Section 23153, the amount of alcohol in the person's blood at the time of the test as shown by chemical analysis of that person's blood, breath, or urine shall give rise to the following presumptions affecting the burden of proof:

  1. If there was at that time less than 0.05 percent, by weight, of alcohol in the person's blood, it shall be presumed that the person was not under the influence of an alcoholic beverage at the time of the alleged offense.
  2. If there was at that time 0.05 percent or more but less than 0.08 percent, by weight, of alcohol in the person's blood, that fact shall not give rise to any presumption that the person was or was not under the influence of an alcoholic beverage, but the fact may be considered with other competent evidence in determining whether the person was under the influence of an alcoholic beverage at the time of the alleged offense.
  3. If there was at that time 0.08 percent or more, by weight, of alcohol in the person's blood, it shall be presumed that the person was under the influence of an alcoholic beverage at the time of the alleged offense.

(b) Percent, by weight, of alcohol in the person's blood shall be based upon grams of alcohol per 100 milliliters of blood or grams of alcohol per 210 liters of breath.

(c) This section shall not be construed as limiting the introduction of any other competent evidence bearing upon the question of whether the person ingested any alcoholic beverage or was under the influence of an alcoholic beverage at the time of the alleged offense.

Added Sec. 84, Ch. 118, Stats. 1998. Effective January 1, 1999. Operative July 1, 1999.

California DUI arrests (also known as DWI) trigger two separate cases: the DMV action, where a person's driving privileges hang in the balance, and the court case, where a variety of DUI punishment is available. For anyone charged with drunk driving in California, it is vital to note that persons arrested for DUI have only 10 days from the date of arrest to request a hearing with the DMV. If someone arrested for drunk driving does not request the hearing on time, his or her license will be suspended, automatically, on the 30th day following the arrest. It is critical for anyone charged with a California DUI or other drunk driving offense to obtain the services of a California DUI lawyer that understands the relationship between the court and DMV.
