Bay Area police officers pull over Waymo robotaxi during DUI operation (www.cbsnews.com)

During a grant-funded DUI enforcement detail in San Bruno over the weekend, Bay Area officers pulled over a Waymo robotaxi after seeing it make an illegal U‑turn at a light — with no human behind the wheel. Police posted the encounter quipping “no driver, no hands, no clue,” but said they could not issue a citation because their forms don’t include a box for “robot.” Waymo confirmed it is investigating, reiterated that its autonomous driving system is designed to follow road rules, and said it remains committed to improving safety. The stop underscores a growing regulatory and operational gap as driverless fleets scale: current traffic-enforcement frameworks assume a human operator and lack clear mechanisms for attributing responsibility when a vehicle breaks a rule. Technically, such maneuvers can arise from perception, localization or planning edge cases, map mismatches, or fleet-management decisions — issues traceable only through vehicle telemetry, logs and remote operator workflows. San Bruno noted pending legislation to let officers issue notices to autonomous-vehicle companies, reflecting a broader push for legal tools, auditability, and clearer accountability as robotaxis expand across the Peninsula, San Francisco and Silicon Valley.
