Automated traffic enforcement (ATE) is one of many safety countermeasures that can be used to enhance roadway safety. Automated enforcement may involve the enforcement of red-light running violations and speed limit violations. The city of Cedar Rapids uses ATE systems to enforce red-light running and speed violations at three signalized intersections on the primary highway system. In addition, the City uses ATE systems to enforce speed violations at four locations along United States Interstate 380 (I-380).  There are two additional locations where the ATE system is in place, including the intersection of 42nd Street and Edgewood Road NE and the intersection of Center Point Road and Collins Road ramp (north side of Highway 100).  A list of all locations is available below.  The Police Department also uses a mobile photo radar vehicle that is typically deployed to areas where citizens are concerned about speeding violations in their neighborhood.

The use of automated traffic enforcement has resulted in a reduction in both crashes and crashes with injuries.  The system advances public interests of traffic safety and safety of emergency responders.

Citations with fines was initiated on July 1, 2019 following a 30-day warning period in June.

If you receive a violation notice in the mail, please follow the instructions included with the citation for the proper procedures to review the violation, pay the citation, or contest the citation.  Additional information is also available through our website:

Contesting Citations

If you have further questions, please email the Cedar Rapids Police Department at atecedarrapids@cedar-rapids.org.  Email is the most efficient form of communication for Automated Traffic Enforcement issues.  You may also call 319-286-5513.


It is the Police Department's policy that an Automated Traffic Enforcement citation be issued to a motorist who exceeds the speed limit by 12 mph or greater.  On August 6, the Police Department was made aware of at least one individual that received a citation for driving 60 mph in a 55 mph zone on U.S. Interstate 380.  This citation was sent in error and will be dismissed.  The Police Department apologizes for this error and would like to restate that speeding violations should be sent only to motorists who are exceeding the speed limit by 12 mph or greater.  While this appears to be an isolated incident, the Police Department encourages anyone who may have received an Automated Traffic Enforcement citation that was less than 12 mph over the posted speed limit to contact the Cedar Rapids Police Department at (319) 286-5513.  Citations that were issued for less than 12 mph over the posted speed limit will be dismissed.


Automated Traffic Enforcement Results

  • There has been a 62% reduction in crashes on U.S. Interstate 380 that involve injuries since the installation of Automated Traffic Enforcement in the City of Cedar Rapids.  In addition, there has been a 37% reduction in overall crashes.

  • There were an average of 5.13 crashes and 2.2 crashes resulting in injury per month before Automated Traffic Enforcement were used in the City.  With the use of Automated Traffic Enforcement Cameras, there have been 3.22 crashes and .84 crashes resulting in injury per month.  There was a 43.2% chance that a crash resulted in an injury before Automated Traffic Enforcement Cameras were in service.  After Automated Traffic Enforcement Cameras were activated, the likelihood decreased to 25.9%.

  • There has been one solitary fatal crash from 2010-2017 when Automated Traffic Enforcement Cameras were activated. From 2003-2009, there were seven fatal crashes when there was no Automated Traffic Enforcement program in place.

  • Since the Automated Traffic Enforcement program was suspended on I-380 in May 2017, the total number of crashes, as well as crashes resulting in injuries have increased.   From May 2017 through March 2019, there have been 6.78 crashes per month and 1.17 crashes with injuries per month.

Benefits of Automated Traffic Enforcement

  • Traffic cameras monitor the interstate more efficiently and effectively than actual law enforcement officers patrolling the dangerous “S-curve.”

  • Using Automated Traffic Enforcement Cameras allow law enforcement officers to respond to other calls for service and public safety concerns.

  • Automated Traffic Enforcement reduces the need for law enforcement officers to make traffic stops in particularly dangerous areas of the interstate. The Automated Traffic Enforcement cameras are located in areas which would be extremely dangerous for both citizens, first responders, and law enforcement to be stationary on the side of the road. 

  • The interstate, especially within the S-curve, is a particularly dangerous location for first responders to assist crash victims.   Automated Traffic Enforcement cameras reduce accidents in the areas which they are located, reducing risk to citizens and law enforcement. 

  • The United States Department of Labor Bureau of Labor Statistics states, “Emergency responders include public-sector law enforcement, firefighting and prevention personnel, and ambulance crews. Workers in these occupations regularly risk harm to themselves to protect the public.”  Between 2011-2015, 192 roadway vehicle incidents accounted for almost one-third of fatal work injuries for law enforcement officers.

  • Utilizing Automated Traffic Enforcement cameras provides the opportunity to modify driving behavior at high-risk and high-crash locations.
