California's jurisdiction over a traffic citation does not end at the state line. Under the Driver License Compact, California reports the conviction to most drivers' home states — but Trial by Written Declaration lets drivers contest without returning to California.
California's Jurisdiction Does Not End at the State Line
A citation issued by a California law enforcement officer is governed by California law regardless of where the cited driver is licensed. The appear-by date on the citation, the court listed on the ticket, and the options available — paying, contesting, or appearing — all run through California's court system. An out-of-state driver's home state license does not extend the deadline or relocate the proceeding.
The Driver License Compact
California is a member of the Driver License Compact (Vehicle Code sections 15000–15028), an agreement for sharing driver record information across state lines. 47 states and the District of Columbia are members, according to the compact membership table kept by AAMVA, the compact's administrator (revised April 2026). Under the Compact, a conviction recorded by a California court is reported to the driver's home state (Vehicle Code section 15022).
Each home state determines how to treat reported convictions. Most states apply their own point systems to out-of-state violations. A California speeding conviction, for example, may result in one or more points on the driver's home-state record, which can affect insurance premiums and license standing depending on that state's rules.
Three states are not members: Georgia, Michigan and Wisconsin. Massachusetts joined in May 2023 and Tennessee in July 2020, so older lists that include them are out of date. Drivers licensed in a non-member state may not have California convictions added to their home records, though California may still record the conviction on its own system.
Consequences of Not Responding
Failing to respond to a California citation by the appear-by date triggers the same consequences for out-of-state drivers as it does for California residents. The court may add a civil assessment of up to $100 under Penal Code 1214.1. Since January 1, 2023, a missed court date is no longer reported to the DMV: AB 2746 repealed Vehicle Code 40509 and 40509.5, the sections California courts used for that. The Driver License Compact reports convictions to the home state, including a conviction from paying or forfeiting bail on the ticket (Vehicle Code 15022), not missed court dates. The case still stays open, and the court can charge a failure to appear under Vehicle Code 40508.
If the debt is eventually referred to California's Franchise Tax Board Court Ordered Debt program, collection can include wage garnishment, bank levies, and state tax refund intercepts for individuals who have California-source income or other California-connected assets.
Trial by Written Declaration Is Available to Out-of-State Drivers
California Vehicle Code 40902, which establishes Trial by Written Declaration, does not restrict eligibility to California residents. Drivers licensed in other states who receive a California infraction citation can file a TBWD to contest the citation entirely by mail, without returning to California for a court appearance.
The driver submits a written declaration describing the driver's account of events and, in most courts, deposits the bail amount at the same time (Vehicle Code 40902(b)); courts that offer online trial by declaration through MyCitations generally cannot require bail in advance unless the court makes specific findings (Government Code 68645.4). The driver then awaits the court's decision. If the driver is found not guilty or the charge is dismissed, any bail paid is refunded. If the citing officer does not submit a declaration, the case may be dismissed, but that is the judge's decision. If the court finds against the driver, any bail paid is applied to the fine. After an unsuccessful TBWD, most courts allow a Trial de Novo — an in-person hearing — if requested within 20 calendar days after the court mails its decision. Courts that offer online trial by declaration through MyCitations do not allow one; the driver can appeal instead.
Extension Requests and Deadlines
Drivers can ask the court for a continuance — an extension of the appear-by date — before the deadline. This can provide additional time to prepare a declaration or gather supporting information. Whether a continuance is granted, and for how long, is at the court's discretion.
Camera Citations and Rental Vehicles
AB 645 speed camera notices and SB 720 red light camera notices are first mailed to the registered owner, which for a rental car is the rental company. The rental company may return an affidavit of nonliability within 30 days with the rental agreement that identifies the renter, and the city's processing agency then mails the notice of violation to the renter (Vehicle Code 22426(e)(6) and 21455.9). The renter can then pay it or contest it through the city's initial review. Separately, a rental agreement may let the company charge its own administrative fee, so check the agreement.
AB 645 speed camera notices and SB 720 civil red light notices do not add DMV points and are civil penalties rather than moving violations; they are contested through the issuing city's initial review, not the TBWD process used for officer-issued tickets. A traditional red light camera ticket under Vehicle Code 21455.5 is different: it is a court citation, a conviction adds 1 DMV point, and it can be contested by TBWD.
