Veh. Code, § 13353.2

(a) The department shall immediately suspend the privilege of a person to operate a motor vehicle for any one of the following reasons:

(1) The person was driving a motor vehicle when the person had 0.08 percent or more, by weight, of alcohol in his or her blood.

(2) The person was under 21 years of age and had a blood-alcohol concentration of 0.01 percent or greater, as measured by a preliminary alcohol screening test, or other chemical test.

(3) The person was driving a vehicle that requires a commercial driver’s license when the person had 0.04 percent or more, by weight, of alcohol in his or her blood.

(4) The person was driving a motor vehicle when both of the following applied:

(A) The person was on probation for a violation of Section 23152 or 23153.

(B) The person had 0.01 percent or more, by weight, of alcohol in his or her blood, as measured by a preliminary alcohol screening test or other chemical test.

(b) The notice of the order of suspension under this section shall be served on the person by a peace officer pursuant to Section 13382 or 13388. The notice of the order of suspension shall be on a form provided by the department. If the notice of the order of suspension has not been served upon the person by the peace officer pursuant to Section 13382 or 13388, upon the receipt of the report of a peace officer submitted pursuant to Section 13380, the department shall mail written notice of the order of the suspension to the person at the last known address shown on the department’s records and, if the address of the person provided by the peace officer’s report differs from the address of record, to that address.

(c) The notice of the order of suspension shall specify clearly the reason and statutory grounds for the suspension, the effective date of the suspension, the right of the person to request an administrative hearing, the procedure for requesting an administrative hearing, and the date by which a request for an administrative hearing shall be made in order to receive a determination prior to the effective date of the suspension.

(d) The department shall make a determination of the facts in subdivision (a) on the basis of the report of a peace officer submitted pursuant to Section 13380. The determination of the facts, after administrative review pursuant to Section 13557, by the department is final, unless an administrative hearing is held pursuant to Section 13558 and any judicial review of the administrative determination after the hearing pursuant to Section 13559 is final.

(e) The determination of the facts in subdivision (a) is a civil matter that is independent of the determination of the person’s guilt or innocence, shall have no collateral estoppel effect on a subsequent criminal prosecution, and shall not preclude the litigation of the same or similar facts in the criminal proceeding. If a person is acquitted of criminal charges relating to a determination of facts under subdivision (a), or if the person’s driver’s license was suspended pursuant to Section 13388 and the department finds no basis for a suspension pursuant to that section, the department shall immediately reinstate the person’s privilege to operate a motor vehicle if the department has suspended it administratively pursuant to subdivision (a), and the department shall return or reissue for the remaining term any driver’s license that has been taken from the person pursuant to Section 13382 or otherwise. Notwithstanding subdivision (b) of Section 13558, if criminal charges under Section 23140, 23152, or 23153 are not filed by the district attorney because of a lack of evidence, or if those charges are filed but are subsequently dismissed by the court because of an insufficiency of evidence, the person has a renewed right to request an administrative hearing before the department. The request for a hearing shall be made within one year from the date of arrest.

(f) The department shall furnish a form that requires a detailed explanation specifying which evidence was defective or lacking and detailing why that evidence was defective or lacking. The form shall be made available to the person to provide to the district attorney. The department shall hold an administrative hearing, and the hearing officer shall consider the reasons for the failure to prosecute given by the district attorney on the form provided by the department. If applicable, the hearing officer shall consider the reasons stated on the record by a judge who dismisses the charges. A fee shall not be imposed pursuant to Section 14905 for the return or reissuing of a driver’s license pursuant to this subdivision. The disposition of a suspension action under this section does not affect an action to suspend or revoke the person’s privilege to operate a motor vehicle under another provision of this code, including, but not limited to, Section 13352 or 13353, or Chapter 3 (commencing with Section 13800).
