NHTSA Investigates If Waymo Robotaxis Are Still Running School Bus Stop Signs

The National Highway Traffic Safety Administration has opened a recall query into whether Waymo’s late-2025 software remedy actually fixed its robotaxis’ failure to stop for school buses with flashing lights and extended stop arms. The agency said most reported incidents occurred after the remedy date, prompting the new review of the voluntary recall, which was completed across the fleet in November 2025. NHTSA’s earlier probe documented the violations in Atlanta and Austin. The inquiry matters because it tests whether over-the-air fixes alone can resolve safety defects in large robotaxi fleets as Waymo expands. Next, watch whether NHTSA escalates to a full defect investigation or demands another remedy, and how Waymo responds.
