How Much Is a Red Light Ticket in California? (2026 Cost & Defense Guide)
If you run a red light in California, the total cost of your ticket is usually $490 to $600, not the $100 base fine most drivers expect. Court fees, county assessments, and state surcharges make red light tickets some of the most expensive common traffic violations in the state.
On top of the fine, you also get 1 DMV point, which can raise your insurance rates for up to 3 years.
This guide breaks down the real cost of a red light ticket in California, why enforcement is so strict, and how drivers successfully fight these tickets.

Why Red Light Tickets Are So Expensive
Red light enforcement is aggressive for one reason: intersections are extremely expensive to build and maintain.
How Much Does a Traffic Light Cost to Install?
A single traffic signal in California typically costs:
- $250,000 to $500,000+ per intersection
- Up to $600,000+ in dense urban areas
Costs include:
- Signal heads and poles
- Underground wiring and trenching
- Traffic controller cabinets
- Pedestrian and ADA systems
- Smart sensors and emergency vehicle preemption
- Design, permits, and construction labor
Cities recover these costs partly through enforcement revenue, which is why red light violations are heavily monitored.
What the Law Says About Traffic Signals
Under California Vehicle Code 21350, the state and local governments must install and maintain official traffic control devices:
“The Department of Transportation shall place and maintain official traffic control devices when and as required by law.”
This means traffic signals must be:
- Properly installed
- Clearly visible
- Functioning correctly
If a signal is obstructed, confusing, or malfunctioning, that can matter legally.
Common Red Light Violations Drivers Get Cited For
- Entering the intersection after the light turns red
- Rolling right turns on red without a complete stop
- Stopping past the limit line or crosswalk
- Disobeying red arrows
- Proceeding when a vehicle sensor fails to detect your car or motorcycle

Officer Errors That Can Weaken a Red Light Ticket
Officers and camera systems still make mistakes. Common issues include:
- No clear statement of when the vehicle entered the intersection
- Failure to note vehicle position relative to the stop line
- Missing details about visibility, sun glare, or weather
- Confusing yellow-light entry with red-light entry
- Misclassifying a legal right turn on red
These gaps matter when you fight the ticket.
What the Officer or Camera Must Prove
To uphold a red light ticket, the government must show:
- The light was red when you entered the intersection
- You failed to stop before the limit line or crosswalk
- The signal was clearly visible and working properly
- For camera tickets, that photos and timing data are accurate
If any of these are unclear or unsupported, the case weakens.
Proven Defenses That Actually Work
Drivers have successfully fought red light tickets using defenses like:
-
Obstructed Signal
A truck, tree, or construction blocked the light. -
Signal Malfunction
The light cycled incorrectly or failed to detect your vehicle. -
Emergency Maneuver
You entered the intersection to avoid a collision or yield to an emergency vehicle. -
Officer Positioning Issue
The officer could not clearly see the stop line or signal. -
Sun Glare or Weather Conditions
The signal was not reasonably visible at the time. -
Poor or New Intersection Markings
Recent changes or faded markings caused confusion.
