Between 2008 and 2019, an estimated 9,227 people were killed in crashes related to red-light running according to the National Highway Traffic Safety Administration (NHTSA). 

The Insurance Institute for Highway Safety found that motorists in urban areas are more likely to be injured in crashes involving red-light running than in any other type of crash. In 2019, 846 people were killed, and an estimated 143,000 were injured in crashes that involved red-light running. About half of those killed in red-light crashes are pedestrians, cyclists and people other than the violator.

Red light cameras train drivers to always stop on red at both camera equipped sites with carry-over to nearby intersections.
