Sometimes signpostedRed light camera (red light safety camera)
Looks like: A camera at the junction, linked to the traffic lights and to sensors just before the stop line or crosswalk.
Catches: Entering the junction after the light has turned red. A right turn on red without a full stop, or where it is banned, may also count.
Used by 351 communities in 2025, in 22 states and Washington DC. Cities with them include Chicago, Denver, New Orleans, New York City, Philadelphia, San Francisco, Seattle and Washington DC. Banned in Idaho, Maine, Mississippi, Montana, New Hampshire, South Carolina, South Dakota, Texas and West Virginia, though some Texas cities still run cameras under contracts signed before the 2019 ban. Many programmes allow up to half a second after the light turns red.
