Red light cameras are not illegal in California. State law expressly authorizes cities and counties to use them, and the California Supreme Court has ruled that the photographs and video they produce are admissible in court. If a camera catches you, expect a citation in the mail with a total cost that typically lands between $490 and $600 once fees and surcharges are added to the $100 base fine, plus one point on your DMV record.
Why They’re Legal
The authorizing statute is California Vehicle Code Section 21455.5. It lets local jurisdictions run automated enforcement at intersections, but it attaches conditions. Warning signs must be posted within 200 feet of the intersection and visible from every direction the camera covers. A law enforcement officer, not the camera vendor, has to review and approve every citation before it goes out. Private companies can install and maintain the hardware, but the decision to ticket a driver stays with the police.1California Legislative Information. California Vehicle Code 21455.5
The last serious legal challenge to the evidence itself fell apart in 2014. In People v. Goldsmith, a driver ticketed in Inglewood argued the camera photographs were inadmissible hearsay. The California Supreme Court unanimously disagreed, holding that the automated images are reliable records rather than testimonial statements and that the prosecution does not need to put on special testimony about the system’s hardware or software before using the pictures.2Justia Case Law. People v. Goldsmith :: 2014 :: Supreme Court of California Decisions That ruling shut down the most common attack on these systems.
What the Ticket Costs
The base fine for running a red light under Vehicle Code Section 21453 is $100. California then stacks penalty assessments, court fees, and state surcharges on top, which is why the total you actually owe usually comes to somewhere between $490 and $600. A rolling right turn on red is treated as the same violation but often totals less, around $217 to $300 depending on the county.
The one-point hit on your driving record is the part that keeps costing you. The point stays visible to insurers for three years, and a red light violation commonly triggers an insurance premium increase of roughly 20 percent at renewal. Over three years, that can outrun the fine itself.
Is the Letter You Got an Actual Ticket?
Before you pay anything, check what you received. Some agencies send a preliminary notice, sometimes called a “snitch ticket,” before they ever file a citation with the court. These come from a police department, not a court. They do not include a due date, a summons, or a court appearance deadline. Their job is to flush out who was driving, so if you fill out the identification section and send it back, the agency then files the real ticket.
A genuine citation comes from the court, names a specific deadline to pay or appear, and identifies the courthouse. If the paper in your hand lacks those things, read it carefully and do not assume you owe money yet.
Once a real citation does arrive, the registered owner is the one who gets it in the mail, but California issues the ticket to the person driving. The camera captures a close-up of the driver’s face for exactly that reason, and state law requires the citation to be mailed within 15 days of the alleged violation.3California Legislative Information.

The Right-Turn-on-Red Trap
A large share of red light camera tickets are not for driving straight through a red light. They are for right turns. California allows a right turn on red, but only after a complete stop behind the limit line or crosswalk.5California Legislative Information. California Vehicle Code 21453 Slowing to a crawl and continuing through is a violation, and the camera captures it the same way it captures someone sailing through at speed. The same complete-stop rule applies to a left turn from a one-way street onto another one-way street facing a red light.
How to Fight It
You have two realistic ways to contest the citation. Both start with pleading not guilty by the deadline on the ticket.
In-Person Trial
At trial, the prosecution puts in the photographs, the video, and typically a declaration from the officer who reviewed the footage. The strongest defense is identity. If the driver’s face in the photo isn’t clearly yours, the prosecution cannot prove you were behind the wheel, and judges have dismissed cases on that basis alone. You can also attack the procedure: a citation mailed more than 15 days after the violation, missing or inadequate signs at the intersection, or an officer who did not actually review the footage before approval are all grounds to challenge the ticket.1California Legislative Information. California Vehicle Code 21455.5
Trial by Written Declaration
Vehicle Code Section 40902 lets you fight the ticket entirely on paper. You write a sworn statement, the officer writes one, a judge reads both and rules by mail. You have to deposit the full bail amount (the fine) with the court first; if you win, you get it back. If you lose, you can still request a new in-person trial, which effectively gives you two shots.6Judicial Branch of California. Traffic Court – Trial by Written Declaration
File the request with the court clerk by the appearance date on your citation. The clerk extends the deadline by 25 calendar days and sends you forms TR-205 and TR-200. Your statement and bail must arrive by the extended due date or the court can deny the trial.
Traffic School to Keep the Point Hidden
If you’d rather pay and move on but want to protect your insurance, traffic school usually works. Completing a state-approved traffic violator school keeps the conviction confidential on your DMV record, so insurers do not see it. You pay the full fine, an administrative fee of roughly $52 to $67 depending on the county, and the cost of the school itself.
- You need a valid California driver’s license. An out-of-state license requires a judge to amend the citation.
- The violation has to be a one-point offense, which a standard red light ticket is.
- You cannot have attended traffic school for another violation within the past 18 months, measured violation date to violation date.
- Some courts only authorize traffic school if you request it before the ticket becomes delinquent.

What Happens If You Ignore It
Doing nothing is the worst option. Miss the deadline and the court can charge you with failure to appear, add a civil assessment, and report the failure to the DMV, which can place a hold on your license so you cannot renew it until the ticket is resolved.8Judicial Branch of California.

Where Cameras Actually Operate
As of early 2026, dozens of California cities and counties run active red light camera programs, including San Francisco, San Jose, Bakersfield, Beverly Hills, Fremont, Santa Monica, Elk Grove, Culver City, Oxnard, and West Hollywood. Los Angeles County operates cameras, but the City of Los Angeles ended its program in 2011 after an audit found it cost more than it generated and did not conclusively improve safety. Programs come and go as councils vote them in or out, and the IIHS keeps a current list of communities with active cameras if you want to check your regular intersections.9IIHS-HLDI.
