What's happened
The US transportation safety regulator has launched a preliminary investigation into a Waymo autonomous vehicle that failed to stop for a school bus in Atlanta, Georgia, on September 22. The incident involved the vehicle passing a stopped bus with flashing lights and deployed stop arm, raising safety concerns. No safety operator was present, and Waymo has committed to software improvements. The investigation covers about 2,000 Waymo vehicles and follows multiple prior reviews of the company's self-driving systems.
What's behind the headline?
The recent NHTSA investigation into Waymo’s handling of school bus interactions underscores the persistent safety challenges faced by autonomous vehicle systems. Despite extensive testing and millions of miles driven, these systems still struggle with complex traffic scenarios involving school buses, which are among the most unpredictable and vulnerable road users.
- The incident reveals that Waymo’s system failed to recognize the bus’s flashing lights and stop arm, approaching from an angle where these signals were not visible.
- The vehicle’s maneuver—passing the bus while students disembarked—raises questions about the system’s ability to interpret and prioritize traffic laws designed to protect children.
- Waymo’s response, including software updates, indicates ongoing efforts to improve safety, but the high number of miles driven without safety operators highlights the risks of deploying these systems at scale.
This investigation will likely lead to stricter regulations and more rigorous testing protocols. It also signals that autonomous vehicle technology still has significant hurdles before it can be fully trusted in complex, real-world environments—especially around school buses. For consumers, this underscores the importance of cautious adoption and continued regulatory oversight to prevent accidents involving vulnerable populations.
What the papers say
The Independent reports that the NHTSA launched an investigation after a Waymo vehicle in Atlanta failed to stop for a school bus with flashing lights and a deployed stop arm, passing the bus while students disembarked. The incident involved the vehicle approaching from a perpendicular side street and maneuvering around the bus, with no safety operator present. Waymo has stated it has already developed improvements and will implement further software updates.
The Guardian highlights that this is part of a broader federal review of about 2,000 Waymo vehicles, following multiple prior investigations into issues like roadway barriers and wrong-lane driving. The article emphasizes that the incident occurred while the vehicle was operating without a safety driver and that Waymo’s fleet is expanding across major US cities and internationally.
The NY Post echoes these points, noting that the NHTSA’s Office of Defects Investigation flagged the incident and that Waymo’s vehicles are involved in ongoing safety reviews. It also mentions Waymo’s plans for international expansion and the company’s assertion that it prioritizes safety around children, despite the recent incident.
TechCrunch provides additional context, reporting that footage from early October prompted the investigation. It describes the vehicle’s maneuver as crossing in front of the bus and turning left, with Waymo claiming the bus was partially blocking the driveway and that the vehicle could not see the flashing lights or stop sign. The article notes Waymo’s previous issues and recalls related to roadway interactions, illustrating the ongoing safety challenges faced by autonomous systems.
How we got here
Waymo, a leader in autonomous vehicle technology, has been expanding its fleet across major US cities and internationally. The company’s vehicles operate without human safety drivers and have accumulated over 100 million miles of driving. Previous investigations have addressed issues like roadway barriers and wrong-lane driving, but this incident highlights ongoing challenges in ensuring safety compliance around school buses, especially as the fleet grows and enters new markets.
