10- If the yellow clearance time is not set according to the minimum requirements, as
shown in the table, would my red light camera ticket be dismissed ?
The chances are very high that a judge would dismiss red light camera tickets based on the
insufficient yellow clearance time, provided that sufficient evidence is produced to show that
the yellow clearance time was not in accordance to the standards.
11- What is the California Vehicle Code Section for red light ticket violation?
The California Vehicle Code Sections that regulate the red light violation for a red light
camera ticket or for a red light ticket issued by a traffic officer are:
12- Is a red light camera ticket defense different for violation of 21453 a in comparison
to violation of 21453 c ?
Yes. The most important issue is that the minimum yellow clearance time requirement for a
tuning movement (left turn or right turn) is 3.0 seconds. Although the minimum yellow
clearance time may be increased taking into consideration various conditions at the
intersection. However, the extended yellow clearance time is not mandatory. Therefore, a
compelling argument must be made to demonstrate that the minimum yellow clearance time
in that particular location created an unsafe situation for the public and the lack of
incremental increase in the yellow clearance time contributed to the red light camera ticket.
13- What are the components in a red light camera system?
A red light camera system consists of the following on-street components:
14- What type of red light camera units are there?
There are three general types of camera units used to automatically record red light
violations, as shown below:
15- How do red light camera systems detect cars running red light ?
There are vehicle detectors that are used to trigger the red light cameras to record a vehicle
speed approaching an intersection and potentially running red lights.
16- What are red light camera vehicle detectors?
A great majority of red light camera systems employ two sets of in ground traffic signal
inductive loops installed near the intersection. However, it is critical for the loops to be
installed in appropriate positions to prevent the issuance of unwarranted red light camera
tickets. Therefore, the integrity of the red light camera system depends heavily on the loop
detectors as well as the minimum yellow clearance time. If the loop detectors are not
properly installed that argument may be used to dismiss red light camera tickets.
17- What is the purpose of the advanced loop detectors?
Most of the software used to operate the red light camera systems rely on data transmitted
from the advanced loops installed in advance on the approach to the intersection. The
purpose of the advanced loops is to estimate the approach speed of a vehicle. Depending
on preset thresholds based on speed, the red light cameras are activated to record the
approaching vehicles that are likely to run red lights.
18- How much is a red light camera fine?

shown in the table, would my red light camera ticket be dismissed ?
The chances are very high that a judge would dismiss red light camera tickets based on the
insufficient yellow clearance time, provided that sufficient evidence is produced to show that
the yellow clearance time was not in accordance to the standards.
11- What is the California Vehicle Code Section for red light ticket violation?
The California Vehicle Code Sections that regulate the red light violation for a red light
camera ticket or for a red light ticket issued by a traffic officer are:
- 21453 a for entering an intersection while there is a round red traffic signal indication.
- 21453 b for not stopping at a red traffic signal indication prior to turning at an
intersection. - 21453 c for entering an intersection while there is a red arrow traffic signal indication.
12- Is a red light camera ticket defense different for violation of 21453 a in comparison
to violation of 21453 c ?
Yes. The most important issue is that the minimum yellow clearance time requirement for a
tuning movement (left turn or right turn) is 3.0 seconds. Although the minimum yellow
clearance time may be increased taking into consideration various conditions at the
intersection. However, the extended yellow clearance time is not mandatory. Therefore, a
compelling argument must be made to demonstrate that the minimum yellow clearance time

The following provides general information and a list of frequently asked questions about
red light violation of California Vehicle Code Section 21453 and red light camera systems:
The technical factors that effect traffic signals at an intersection could play a vital role on a
driver’s behavior when approaching a signalized intersection and result in a red light ticket.
This is especially true for locations equipped with red light camera enforcement systems. If
the traffic signal and the red light cameras are not properly installed and operated according
to design standards, then it is likely that a driver may enter the intersection during the red
light cycle without the intention to do so and receive a red light ticket. This is where a
detailed knowledge of red light camera systems and traffic signal operating standards could
be vital to beat red light tickets in traffic court.
To successfully fight red light tickets a defendant must be able to point out that there was
a problem with the red light cameras and the traffic signal regulating driver conduct, or
some other technical issue that renders the red light violation charge against the driver
invalid.
Virtually every jurisdiction is subject to stringent rules and regulations for operation of red
light camera systems and traffic signal design and operation. As a result, violations of those
regulations can provide a defense for an officer issued red light ticket or a red light camera
ticket.

RED LIGHT CAMERA TICKET
For red light camera tickets, if you were not the driver of the vehicle at the time of the
alleged red light violation, then you are not responsible for the red light camera ticket. The
red light camera ticket is intended for the driver of the vehicle not the registered owner.
However, the red light camera ticket is mailed to the registered owner of the vehicle. If you
were not the driver during the alleged red light camera violation, all you have to do is to
complete a form of non-responsibility and mail it to the issuing agency as directed on the
red light camera ticket. However, you must identify the driver by providing the driver’s
name, address and etc. The traffic court will not accept your your non-responsibility form if
you are unable to identify the driver during the alleged red light camera violation and you
will be the assumed driver and be held responsible for the red light camera ticket.
If you were the driver of the vehicle and your face appears clearly in the photograph, then
to fight red light camera ticket effectively you would need to look at the detailed red light
camera system operation and the traffic signal related design and operational standards.
However, for the layperson to analyze the red light camera system and the traffic signal
operation at an intersection could be at a minimum extremely challenging to impossible.
Our red light camera ticket experts have years of experience in the design and operation of
red light camera systems and traffic signal design and operation. They will review the red
light camera ticket and the traffic signal operation at the specific intersection where the red
light camera ticket was issued and prepare a defense citing specific standards and codes
that would help to beat red light camera tickets.
More information in form of questions and answers on red light camera tickets and
technical factors that are critical to successfully fight red light camera tickets in traffic
court:
The use of red light camera systems for automated enforcement of red light violations at
signalized intersections is on the rise in United States, especially in cash strapped
California. Click on the highlighted text for a list of Red Light Camera Locations in
California by City name.
1- Why do governmental agencies install red light camera systems?
The Official buzz word used by almost all of the governmental agencies to justify the
installation of red light camera systems is “Safety”. Most agencies claim that red light
cameras reduce the number of accidents at intersections by reducing the number of red
light violations. According to a 2004 study by National Highway Traffic Safety
Administration (NHTSA), crashes caused by running red light resulted in 854 fatalities and
more than 168,000 injuries. Such studies have been used to make compelling arguments
for the installation of red light camera systems. However, rarely there is a reference made
to before and after studies that analyze the number of accidents after the red light camera
systems are installed.
2- Do red light camera systems reduce accidents at intersection?
According to a comprehensive study conducted by Federal Highway Administration, which
included 132 intersections across the country; including El Cajon, San Diego and San
Francisco, the use of red light camera systems generated the following results:
As it is evident in the data the red light camera systems reduce one type of accident,
however they result in an increase in another. Therefore, a blanket statement that
automated red light camera enforcement is used to increase safety at signalized
intersections is not accurate.
3- How are the locations for red light camera systems selected for installation?
Most agencies conducted an analysis of the accidents at signalized intersection. The
locations with the highest level of accidents due to running red light are selected for
evaluation. According to standards set by FHWA, initially the agencies are supposed to look
at deficiencies in the design and configuration of traffic signals at intersections that may
contribute to red light violation related accidents. For example, inadequate stopping
distance or limited visibility of the traffic signal may be the reason for running red light.
After all possible physical improvements have been made to improve the intersection then
a red light camera system may be considered for installation. One of the most important
considerations for reducing running red light violations at intersections is the traffic signal
timing. Research studies have shown that inadequate traffic signal timing tends to increase
running red light violations.
4- How do I know if possible engineering counter-measures were implemented to
reduce running red light violations at an intersection where I received a red light
camera ticket ?
This is where things get a little more technical. Most people will not be able to determine if
a traffic signal design, installation and the operation was done according to industry
standards or any modifications made to the red light operation. It takes years of
experience and expertise to be able to determine the deficiencies of a traffic signal
operation at an intersection, especially to fight red light camera tickets in traffic court. This
is where the help of a red light camera ticket expert can make a difference between getting
the red light camera ticket dismissed or not. However, we have listed a few of the
deficiencies here; traffic signal head visibility, additional traffic signal head, all red
clearance interval, yellow clearance time, intersection warning signs, advanced yellow
flashing lights, approach speed, traffic signal coordination, advanced vehicle detection.
5- Can a red light camera ticket be dismissed based on deficiencies in the traffic signal
operation?
Yes, driver behavior at a red light is influenced by the design and the operation of traffic
control devices including traffic signals. Therefore, drivers are more likely to run red lights
at locations where the traffic signal installation and the operation were not in compliance
with the State and Federal standards. The most important issue to successfully fight red
light camera tickets in traffic court is obviously first to be able to identify the deficiencies
in the red light camera system and the traffic signal operation and then be able to explain
it to the judge in traffic court in a clear and concise manner with detailed exhibits and
references to the specific California Vehicle Code sections and other applicable red light
manuals.
6- How does the yellow clearance time affect red light camera tickets ?
After the installation of a red light camera system, the yellow clearance time will affect the
number of red light camera tickets issued at a location. An increase in the yellow clearance
time will result in a decrease in the number of red light camera tickets and a decrease in
the yellow clearance time interval will result in an increase in the number of red light
camera tickets.
7- To reduce running red light violations and increase safety, why the agencies do not
increase the yellow clearance time at intersections?
That is a very valid question. Most probable answer is that red light camera tickets
generate a tremendous amount of money for most governmental agencies and the private
vendors that operate the cameras (see red light camera ticket cost) .
8- Can inadequate yellow clearance time at an intersection be grounds to dismiss red
light camera ticket ?
Yes, if the traffic signal timing is set in such a manner that the yellow clearance time does
not meet the minimum yellow clearance time, then that can be grounds to dismiss red light
camera tickets.
9- How long should the minimum yellow clearance time be at an intersection for red
light camera ticket?

2- Do red light camera systems reduce accidents at intersection?
According to a comprehensive study conducted by Federal Highway Administration, which
included 132 intersections across the country; including El Cajon, San Diego and San
Francisco, the use of red light camera systems generated the following results:
- 25% decrease in total right-angle accidents
- 16% reduction in injury right angle accidents
- 15% increase in total rear-end accidents
- 24% increase in injury rear-end accidents
As it is evident in the data the red light camera systems reduce one type of accident,
however they result in an increase in another. Therefore, a blanket statement that
