Vehicle Code Section 23610-23614

23610

  1. 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.
  2. 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.
  3. 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.

23614

  1. In addition to the requirements of Section 23612, a person who chooses to submit to a breath test shall be advised before or after the test that the breath-testing equipment does not retain any sample of the breath and that no breath sample will be available after the test which could be analyzed later by that person or any other person.
  2. The person shall also be advised that, because no breath sample is retained, the person will be given an opportunity to provide a blood or urine sample that will be retained at no cost to the person so that there will be something retained that may be subsequently analyzed for the alcoholic content of the person's blood. If the person completes a breath test and wishes to provide a blood or urine sample to be retained, the sample shall be collected and retained in the same manner as if the person had chosen a blood or urine test initially.
  3. The person shall also be advised that the blood or urine sample may be tested by either party in any criminal prosecution. The failure of either party to perform this test shall place neither a duty upon the opposing party to perform the test nor affect the admissibility of any other evidence of the alcoholic content of the blood of the person arrested.
  4. No failure or omission to advise pursuant to this section shall affect the admissibility of any evidence of the alcoholic content of the blood of the person arrested.
