Article 2. Prior And Separate Offenses of California Vehicle Code >> Division 11.5. >> Chapter 4. >> Article 2.

(a) For the purposes of this division, Section 13352, and Chapter 12 (commencing with Section 23100) of Division 11, a separate offense that resulted in a conviction of a violation of subdivision (f) of Section 655 of the Harbors and Navigation Code or of Section 191.5 of, or subdivision (a) of Section 192.5 of, the Penal Code is a separate offense of a violation of Section 23153.
  (b) For the purposes of this division and Chapter 12 (commencing with Section 23100) of Division 11, and Section 13352, a separate offense that resulted in a conviction of a violation of subdivision (b), (c), (d), or (e) of Section 655 of the Harbors and Navigation Code is a separate violation of Section 23152.

(a) In any case charging a violation of Section 23152 or 23153 and the offense occurred within 10 years of one or more separate violations of Section 23103, as specified in Section 23103.5, that occurred on or after January 1, 1982, 23152, or 23153, or any combination thereof, that resulted in convictions, the court shall not strike any separate conviction of those offenses for purposes of sentencing in order to avoid imposing, as part of the sentence or term of probation, the minimum time of imprisonment and the minimum fine, as provided in this chapter, or for purposes of avoiding revocation, suspension, or restriction of the privilege to operate a motor vehicle, as provided in this code.
  (b) In any case charging a violation of Section 23152 or 23153, the court shall obtain a copy of the driving record of the person charged from the Department of Motor Vehicles and may obtain any records from the Department of Justice or any other source to determine if one or more separate violations of Section 23103, as specified in Section 23103.5, that occurred on or after January 1, 1982, 23152, or 23153, or any combination thereof, that resulted in convictions, have occurred within 10 years of the charged offense. The court may obtain, and accept as rebuttable evidence, a printout from the Department of Motor Vehicles of the driving record of the person charged, maintained by electronic and storage media pursuant to Section 1801 for the purpose of proving those separate violations.
  (c) If any separate convictions of violations of Section 23152 or 23153 are reported to have occurred within 10 years of the charged offense, the court shall notify each court where any of the separate convictions occurred for the purpose of enforcing terms and conditions of probation pursuant to Section 23602.

Only one challenge shall be permitted to the constitutionality of a separate conviction of a violation of Section 14601, 14601.2, 23152, or 23153, which was entered in a separate proceeding. When a proceeding to declare a separate judgment of conviction constitutionally invalid has been held, a determination by the court that the separate conviction is constitutional precludes any subsequent attack on constitutional grounds in a subsequent prosecution in which the same separate conviction is charged. In addition, any determination that a separate conviction is unconstitutional precludes any allegation or use of that separate conviction in any judicial or administrative proceeding, and the department shall strike that separate conviction from its records. Pursuant to Section 1803, the court shall report to the Department of Motor Vehicles any determination upholding a conviction on constitutional grounds and any determination that a conviction is unconstitutional. This section shall not preclude a subsequent challenge to a conviction if, at a later time, a subsequent statute or appellate court decision having retroactive application affords any new basis to challenge the constitutionality of the conviction.

A conviction of an offense in any state, territory, or possession of the United States, the District of Columbia, the Commonwealth of Puerto Rico, or the Dominion of Canada that, if committed in this state, would be a violation of Section 23152 or 23153 of this code, or Section 191.5 of, or subdivision (a) of Section 192.5 of, the Penal Code, is a conviction of Section 23152 or 23153 of this code, or Section 191.5 of, or subdivision (a) of Section 192.5 of, the Penal Code for the purposes of this code.
