Red Light Running

Independently published results of traffic safety research and studies from various sources.


AAA Foundation for Traffic Safety finds the Majority of Americans Support Photo Enforcement

"A majority of drivers express some opinions consistent with a belief that traffic safety is a serious issue that warrants attention. They perceive unsafe driver behaviors such as speeding, talking on cell phones, texting and e-mailing, and red light running as serious threats to their personal safety..."
