California Code, Vehicle Code - VEH § 40261

(a) Within 10 days from the mailing of a notice of delinquent toll evasion violation, any person or his or her agent, may request by mail or in person a photostatic copy or an electronically produced facsimile of the original notice of toll evasion violation.  The issuing agency may charge a fee sufficient to recover the actual cost of providing the copy, not to exceed two dollars ($2).  Within 15 days of the request, the processing agency shall mail or otherwise provide the copy.  Until the issuing agency complies with a request for a copy of the original notice of toll evasion violation, the processing agency may not proceed pursuant to subdivision (i) of Section 22651, or Section 22651.7 or 40267.

(b) If the description of the vehicle on the notice of toll evasion violation does not match the department's corresponding vehicle registration record, the processing agency may, on written request of the person, cancel the notice of toll evasion violation without the necessity of an appearance by that person.
