Red-Light Running

IMPORTANT NOTE: The Federal Highway Administration (FHWA) does not own, operate, regulate, or oversee red-light camera (RLC) systems, nor do we formally track or inventory their use in the United States. A red-light camera is an enforcement tool, not a traffic control device, and so is not governed by the Federal Manual on Uniform Traffic Control Devices. Questions about their operation in a specific State or city, or about tickets/citations received, should be directed to the police, traffic engineering or public works department in that State or city.

Red-light running (RLR) is a serious signalized intersection safety issue. RLR-related crashes result in several hundred people killed each year in the United States. The following table summarizes the number of people killed each year in RLR-related crashes in the United States, based on data extracted from the NHTSA Fatality Analysis and Reporting System (FARS).

Year Total U.S. Traffic Fatalities Intersection Fatalities Signalized Intersection Fatalities RLR-Related Fatalities RLR-Related Fatalities involving a Pedestrian or Bicyclist
2010 32,999 8,633 2,477 687 26
2011 32,479 8,317 2,442 723 45
2012 33,782 8,851 2,618 701 40
2013 32,894 8,676 2,622 708 29
2014 32,675 8,661 2,675 710 44
