San Mateo County Traffic School

San Mateo County covers the Peninsula between San Francisco and Santa Clara County, with the bay to the east and the ocean to the west. US 101 follows the bay shore from South San Francisco to East Palo Alto, and Interstate 280 runs along the hills from Daly City. Highway 1 hugs the coast through Pacifica and Half Moon Bay, and State Route 35 follows the ridge as Skyline Boulevard. Route 92 runs from Half Moon Bay to the San Mateo-Hayward Bridge, and Route 84 through Redwood City to the Dumbarton Bridge. The Census Bureau counts 743,568 residents in 20 cities.

The California Office of Traffic Safety counted 3,333 people killed or injured in San Mateo County crashes in 2023, which ranks the county 36th of 58. In these rankings 1st is the worst. Two figures rank much higher. Bicyclists killed or injured numbered 216, 7th in the state, and pedestrians aged 65 or older numbered 45, 6th.

San Mateo County Superior Court hears every traffic arraignment in one building, the Northern Branch at 1050 Mission Road in South San Francisco. The court says this holds wherever in the county you were cited, whether in East Palo Alto, Half Moon Bay or Daly City. If you need to appear, reserve a court date with a clerk by phone at (650) 363-4300. The Redwood City Area of the California Highway Patrol covers roads across parts of the county, and its Hayward Area takes a small piece near the Dumbarton Bridge, so a CHP ticket lands in the same Superior Court as one from a city police officer. Tickets for drivers under 18 go to the county Probation Department, not the court, at (650) 312-8887.

It is easy to assume a ticket goes to Redwood City, the county seat, where the Hall of Justice at 400 County Center is the court's Southern Branch. The court lists civil, criminal, family law, probate and small claims cases there, and its citation page says no other services for traffic cases are available at the Redwood City location. The hearing schedule still places some traffic trials in that building, so ask the clerk before you plan on one. On the DMV's code list, the county's one adult traffic code, 41470, is named Southern Traffic Division, Redwood City, and the Northern Branch has none. That code is a label in the DMV system, not a place to appear.

When the court allows traffic school, you pay the full bail plus a non-refundable administrative fee before you can enroll, and the court sets the date by which you must finish. If the traffic school date passes without a completion, the fee is forfeited as bail and the DMV is told of the conviction. Miss the citation's own due date and the court can add a civil assessment and place a hold on your license.
