What the probe targets
The US National Highway Traffic Safety Administration (NHTSA) is examining whether Waymo's autonomous taxi fleet still illegally passes school bus stop signs. The agency's latest review directly questions the effectiveness of the company's 2025 software recall.
Why it matters
Stopping for school buses is one of the most sensitive safety tests for autonomous vehicles. A robotaxi breaking this rule is a serious concern both for children's safety and for public trust in driverless cars.
What the recall covered
Waymo updated its software in 2025 to fix how its vehicles recognize school bus stop signs. NHTSA's new investigation tests whether that fix actually works on the road.
What comes next
The federal review could lead to further corrective steps or enforcement discussions if problems persist. Waymo has not yet offered a detailed response.
