Where are cameras currently being used?
Photo red light enforcement has been used in the United States for more than 15 years and in Europe for nearly 30 years. Systems are used in the United States in more than 160 communities in 25 states, including Tennessee, Georgia, Arizona, California, Maryland, and Ohio. Studies indicate a substantial decrease in traffic crashes at intersections and on roadways where traffic enforcement cameras are installed. Organizations such as the National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety have information and web sites available on this subject.
