San Bruno Police Pull Over Driverless Waymo for Illegal U‑Turn, Exposing Ticketing Gap

State rules to hold AV operators accountable do not take effect until July 2026.

Overview

  • Officers on a DUI enforcement operation in San Bruno watched a Waymo make an illegal U-turn at a light and initiated a stop.
  • Police could not issue a moving-violation citation because there was no human driver, noting their forms have no category for a robot, and said it was a first for the responding officers.
  • The vehicle yielded to lights and siren, and officers spoke with a Waymo representative through the car’s two-way communication system.
  • Waymo said it is investigating the incident and reiterated that its autonomous system is designed to follow traffic laws.
  • California law currently bars moving-violation tickets to driverless cars, with a new notice-of-noncompliance process and DMV reporting set to begin in July 2026; Waymo has been expanding service in the Bay Area, including recent airport approvals, and has faced a recall and an NHTSA investigation in the past two years.
