Red light running happens frequently and is often deadly. In 2019, 846 people were killed in crashes that involved red light running. In 2019, an estimated 143,000 people were injured in red light running crashes.
An IIHS study found that cameras reduced the fatal red light running crash rate of large cities by 21 percent and the rate of all types of fatal crashes at signalized intersections by 14 percent.
Among drivers involved in 2019 fatal red light running multiple-vehicle crashes, the red light runners were more likely than other drivers to be male, to be younger, and to have prior crashes or alcohol-impaired driving convictions. The red light runners also were more likely to be speeding or alcohol-impaired at the time of the crash and less likely to have a valid driver's license.
