How to Fight a Red-Light Camera Ticket in California (2026)
Step 1: Is this a real citation or a courtesy notice?
Did this come from a court (real citation) or is it a 'courtesy notice'? Many California red-light camera mailings are unfiled courtesy notices — they look like tickets but were never filed with a court. Verify before you respond.
Signs it is a REAL citation
- Has a court case number
- Bears an official court seal or agency seal
- Says 'Notice to Appear' and names a specific court
- Has an appearance date or payment due date
- References criminal infraction or civil penalty with a specific deadline
Signs it is a SNITCH TICKET (courtesy notice)
- Says 'Courtesy Notice: This Is Not A Ticket' or similar language
- Displays a vendor URL (e.g., ATS, Redflex, Verra Mobility) for 'more information'
- Says 'do not contact the court' or 'no points will be assessed'
- Has no court case number
- Fine amount is listed as 'voluntary' or no mandatory payment language
How to verify — county superior court traffic portal
Look up the citation number on the county superior court traffic portal for the county where the alleged violation occurred. If no case is found, it is an unfiled courtesy notice.
If the citation number does not appear in the county superior court traffic portal, this is an unfiled courtesy notice — you are not legally required to respond or pay. Do NOT identify the driver to the vendor or anyone else. The Fifth Amendment protects you from being compelled to incriminate yourself or others. Verify on the court portal first; if not filed, you may disregard this notice.

California's Two Red-Light Camera Tracks
Which track applies to you determines your liability, fine, forum, and document type. Identify your track from the detection hints below, then review the applicable defenses.

Driver Not Identifiable in Photo
highCVC §21455.5 requires a clear photo of the driver's face for a valid citation. If the image does not clearly identify the registered owner as the driver, the citation cannot stand.

CVC §40518 (registered owner affidavit identifying actual driver)

California Red-Light Camera Ticket FAQ
What is a snitch ticket in California?
A 'snitch ticket' (also called a courtesy notice) is a mailing from a red-light camera vendor that is NOT a filed court citation. It looks like a ticket but has language like 'Courtesy Notice: This Is Not A Ticket,' no official court case number, and a vendor URL instead of court contact info. Because it has not been filed with the court, you are not legally required to respond or pay. Verify on the county superior court traffic portal before taking any action.
Are California red-light camera tickets owner or driver liable?
It depends on which track the citation is from. Legacy red-light cameras (cities not adopting SB720) issue citations to the DRIVER as a criminal infraction (CVC §21455.5) — no conviction without driver identification. SB720 cameras (opt-in cities, eff. 2026-01-01) are owner-liable civil citations, $100 flat, no DMV points. You need to identify your track before deciding how to respond.
Do California red-light camera tickets add points to my license?
It depends on the track. Legacy RLC citations are criminal infractions — if convicted, 1 DMV point is assessed and insurers may raise rates. SB720 civil citations have no DMV points and no insurance channel. AB645 speed camera citations are also civil with no points.
How do I contest a California legacy red-light camera ticket (Trial by Written Declaration)?
Legacy RLC citations can be contested by Trial by Written Declaration under CVC §40902. You file a written statement (Judicial Council Form TR-205) before your appearance date and post bail equal to the fine. If the citing officer fails to file a response, judgment is typically entered in your favor. If found guilty in writing, you can request a Trial de Novo (in-person new trial) within 20 days of the mailed notice.
What is the 15-day mailing deadline for California red-light camera tickets?
Under CVC §40518, a Notice to Appear for a red-light camera violation must be mailed to the registered owner within 15 days of the date of the alleged violation. A notice postmarked after the 15-day window is untimely and the citation should be dismissed on that ground.
