Federal motor vehicle safety regulators intensified administrative scrutiny over autonomous commercial transportation systems.
On November 13, 2026, the National Highway Traffic Safety Administration formally confirmed the opening of an expedited recall query into Alphabet subsidiary Waymo. The query encompasses 2,895 autonomous vehicles equipped with fifth-generation automated driving hardware across Arizona, California, and Texas. According to official defect notification documentation published by NHTSA's Office of Defects Investigation, federal regulators are reviewing recurring failures involving school bus traffic regulations. In November 2025, Waymo deployed an over-the-air software update intended to train perception neural networks to identify extended stop arms and flashing red signals on school buses; federal field reports proved that the majority of documented violations occurred after that software patch.
Surveillance logs compiled by local school districts revealed that Waymo robotaxis repeatedly failed to yield, executing unlawful passes alongside stopped buses discharging students; in one documented incident, an autonomous vehicle crossed perpendicularly in front of a school bus from the right curb. The NHTSA Office of Defects Investigation said in published regulatory filings that it had opened an official Recall Query to evaluate the real-world effectiveness of Waymo's software remedy following reports that autonomous vehicles continued illegally passing stopped school buses across active operational territories.
The Austin Independent School District formally demanded that Waymo suspend all automated commercial passenger operations during designated morning and afternoon student bus transit windows. Waymo corporate communications officers stated that the company is cooperating fully with federal inquiries.
NHTSA demanded that Waymo furnish extensive engineering telemetry, raw video logs, and sensor calibration metrics by mid-December, and federal investigators will evaluate whether commercial expansion permits must be paused pending rigorous re-testing.
