According to documents from the National Highway Traffic Safety Administration (NHTSA), after Waymo completed a software update on November 17, 2025, aimed at addressing robotaxi violations involving bypassing stopped school buses, such incidents have continued unabated, with the majority of reported events occurring post-update deployment. The NHTSA Office of Defects Investigation has initiated a "recall inquiry" to assess whether Waymo's remedial measures are sufficient. Previously, regulators had launched a preliminary investigation into a single incident where a Waymo autonomous vehicle bypassed a stopped school bus in Atlanta, which was displaying red warning lights and had students disembarking. Austin Independent School District officials subsequently reported at least five similar occurrences.
