Waymo has paused its driverless ride-hailing service in four U.S. cities after its robotaxis repeatedly struggled with heavy rain and flooded roads, an issue serious enough to have prompted a vehicle recall just a week earlier. The Alphabet-owned company confirmed it halted operations in Atlanta, San Antonio, Dallas and Houston as severe weather swept across the Southeast and Texas.
A robotaxi stuck in an Atlanta flood
The latest suspension was triggered when one of Waymo's robotaxis was spotted driving through a flooded street in Atlanta before becoming stuck for about an hour, according to local news reports. The vehicle was unoccupied and was later recovered and removed from the scene. "Safety is Waymo's top priority, both for our riders and everyone we share the road with," the company said, adding that an empty vehicle "encountered a flooded road and stopped" during a period of intense rainfall.
An unfinished fix
The flooding problem is not new. Waymo issued a software recall the prior week but acknowledged it had not yet finished developing a "final remedy" for avoiding flooded areas. Instead, it shipped an update placing restrictions in locations and at times with an elevated risk of encountering a flooded, higher-speed roadway. The company said the Atlanta storm produced so much rain that flooding occurred before the National Weather Service issued a flash flood warning, removing one of the signals Waymo relies on to prepare its fleet for poor weather.
Regulators watching closely
The National Highway Traffic Safety Administration said it is aware of the Atlanta incident, is in communication with Waymo, and will take action if necessary. The flooding episodes add to scrutiny of the company, which is already facing investigations tied to its robotaxis passing stopped school buses and a separate January incident in which a vehicle struck a child in Santa Monica, California. As Waymo expands its service area, real-world edge cases like severe weather continue to test the limits of autonomous driving. The challenges echo broader debates about how driverless systems handle unpredictable conditions, a theme explored in coverage of safety frameworks for connected robot vehicle networks and delivery robot mishaps during urban integration.
Caution as a default
A Waymo spokesperson said the company paused service in Dallas and Houston out of an abundance of caution ahead of forecasted severe weather, rather than in response to a specific incident. The move underscores how operators are balancing rapid expansion with conservative safety choices, a tension also seen as autonomous machines normalize in public spaces and prompt new city regulations. Waymo has not said when service will resume in the affected cities.
