If you are talking about California Vehicle Code 23593a, then that is a statute that requires a court to advise a person charged with DUI of certain provisions of the law. The statute is set out below and the court must make the statements set out in the statute.
23593. (a) The court shall advise a person convicted of a violation of Section 23103, as specified in Section 23103.5, or a violation of Section 23152 or 23153, as follows:
"You are hereby advised that being under the influence of alcohol or drugs, or both, impairs your ability to safely operate a motor vehicle. Therefore, it is extremely dangerous to human life to drive while under the influence of alcohol or drugs, or both. If you continue to drive while under the influence of alcohol or drugs, or both, and, as a result of that driving, someone is killed, you can be charged with murder."
(b) The advisory statement may be included in a plea form, if used, or the fact that the advice was given may be specified on the record.
(c) The court shall include on the abstract of the conviction or violation submitted to the department under Section 1803 or 1816, the fact that the person has been advised as required under subdivision (a).
