IIHS – Red light running

Updated: Oct 13, 2021

Red light running happens frequently and is often deadly. In 2017, 890 people were killed in crashes that involved red light running.

Red light cameras are an effective way to discourage red light running. Enforcement is the best way to get people to comply with any law, but it’s impossible for police to be at every intersection. Cameras can fill the void. 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.

Cameras don’t violate privacy. Driving is a regulated activity, and people who obtain licenses are agreeing to abide by certain rules. Red light cameras are a way to catch people who break those rules, just like traditional enforcement.

Proper signal timing makes intersections safer. Adequate yellow time reduces red light running and leads to fewer crashes.
