Cal. Veh. Code § 13208

In any criminal proceeding, without regard to its disposition, wherein the defendant is charged with a violation of Division 11 (commencing with Section 21000), the court may, if it has reason to believe that any of the conditions specified in Section 12805 or 12806 exist, recommend to the department that an investigation be conducted to determine whether the driving privilege of that person should be suspended or revoked. In making the recommendation, the court shall state the basis for the belief that the condition exists and whether the defendant relied upon the condition as a part of his or her defense. The department may provide a form for the court’s convenience.
