Napa has installed automatic red-light cameras at Highway 29 and Trower Avenue and at Soscol and Imola avenues. The installation completes the city's four-camera network, with all four intersections classified as high-injury in the city's 2022 Local Roadway Safety Plan.
Why it matters
The camera network is intended to reduce car crashes in town. At the first camera site, Soscol and Lincoln avenues, the city reports crashes fell from 10 in the 605 days before enforcement to two in the 605 days after.
The city reports 14,799 warnings and violations from its first camera in nine months, and two crashes at that intersection in 605 days of enforcement versus 10 in the 605 days before. Whether the same pattern will appear at the new sites is not yet known.
The players
Caltrans
The California Department of Transportation, which owns the state highway rights-of-way where the new cameras are located and issued the city its construction permit.
Napa City Council
The city's elected legislative body, which approved the four-camera red-light program in August 2023.
The details
The cameras record video and still photos covering all four approaches to each intersection. Caltrans granted the city a construction permit in July 2026 because the new cameras sit on state rights-of-way, and once online they will issue a 30-day warning period before citations begin.
Timeline
August 2023: City Council approved the four red-light cameras.
2025: The first two cameras were installed at Lincoln and Soscol avenues and at Redwood Road and Solano Avenue.
July 2026: Caltrans granted the city a construction permit for the new cameras.
Seasonal Patterns
The four camera sites were each classified as high-injury in Napa's 2022 Local Roadway Safety Plan, and the new installations carry that plan's identified intersections forward into enforcement. The outcome at Soscol and Lincoln will be compared against the city's pre-enforcement crash baseline.
Drivers approaching these four intersections should expect a 30-day warning period before citations begin. Fines are $445 for running a red light or turning left on a red arrow, $217 for stopping late then turning right, and $363 for turning right where no right on red is posted.
The takeaway
Drivers at these four intersections should treat red lights and no-turn-on-red signs strictly, since fines range from $217 to $445. Checking the city's enforcement schedule before the warning period ends can help avoid a first citation.
What happens next
The two newly installed cameras will begin issuing citations after a 30-day warning period once they come online.
