Who calibrates Napa’s traffic signals?

The City of Napa Public Works Department is responsible for ensuring that the traffic signal timing, including the yellow light timing, meets the requirements outlined in the CA Manual on Uniform Traffic Control Devices (MUTCD). 

Staff from both the PD Red Light Camera Unit and Public Works Department visits each intersection quarterly to confirm the yellow light timing meets MUTCD standards. CalTrans is responsible for the intersections on State Highways.
