Section 40305 Of Article 1. Arrests From California Vehicle Code >> Division 17. >> Chapter 2. >> Article 1.

. (a) Whenever a nonresident is arrested for violating any section of this code while driving a motor vehicle and does not furnish satisfactory evidence of identity and an address within this state at which he or she can be located, he or she may, in the discretion of the arresting officer, be taken immediately before a magistrate within the county where the offense charged is alleged to have been committed, and who has jurisdiction over the offense and is nearest or most accessible with reference to the place where the arrest is made. If the magistrate is not available at the time of the arrest and the arrested person is not taken before any other person authorized to receive a deposit of bail, and if the arresting officer does not have the authority or is not required to take the arrested person before a magistrate or other person authorized to receive a deposit of bail by some other provision of law, the officer may require the arrested person, if he or she has no satisfactory identification, to place a right thumbprint, or a left thumbprint or fingerprint if the person has a missing or disfigured right thumb, on the notice to appear as provided in Article 2 (commencing with Section 40500). Except for law enforcement purposes relating to the identity of the arrestee, no person or entity may sell, give away, allow the distribution of, include in a database, or create a database with, this print.
  (b) (1) A person contesting a charge by claiming under penalty of perjury not to be the person issued the notice to appear may choose to submit a right thumbprint, or a left thumbprint if the person has a missing or disfigured right thumb, to the issuing court through his or her local law enforcement agency for comparison with the one placed on the notice to appear. A local law enforcement agency providing this service may charge the requester no more than the actual costs. The issuing court may refer the thumbprint submitted and the notice to appear to the prosecuting attorney for comparison of the thumbprints. When there is no thumbprint or fingerprint on the notice to appear, or when the comparison of thumbprints is inconclusive, the court shall refer the notice to appear or copy thereof back to the issuing agency for further investigation, unless the court finds that referral is not in the interest of justice.
  (2) Upon initiation of the investigation or comparison process by referral of the court, the court shall continue the case and the speedy trial period shall be tolled for 45 days.
  (3) Upon receipt of the issuing agency's or prosecuting attorney's response, the court may make a finding of factual innocence pursuant to Section 530.6 of the Penal Code if the court determines that there is insufficient evidence that the person cited is the person charged and shall immediately notify the Department of Motor Vehicles of its determination. If the Department of Motor Vehicles determines the citation or citations in question formed the basis of a suspension or revocation of the person's driving privilege, the department shall immediately set aside the action.
  (4) If the prosecuting attorney or issuing agency fails to respond to a court referral within 45 days, the court shall make a finding of factual innocence pursuant to Section 530.6 of the Penal Code, unless the court determines that a finding of factual innocence is not in the interest of justice.
  (5) The citation or notice to appear may be held by the prosecuting attorney or issuing agency for future adjudication should the arrestee who received the citation or notice to appear be found.
