Waymo Halts Robotaxi Services in Four Cities Amid Flooding Challenges
Waymo, the autonomous vehicle subsidiary of Alphabet, has temporarily suspended its robotaxi operations in four major U.S. cities—Atlanta, San Antonio, Dallas, and Houston—due to ongoing difficulties in navigating heavy rainfall and flooded roadways. This decision follows a recent software recall aimed at addressing these weather-related challenges.
Incident in Atlanta
On May 20, 2026, a Waymo robotaxi was observed driving through a flooded street in Atlanta, Georgia. The vehicle eventually became immobilized for approximately an hour before being retrieved. In response, Waymo paused its services in Atlanta to assess and rectify the issue. The company emphasized its commitment to safety, stating, Safety is Waymo’s top priority, both for our riders and everyone we share the road with. During a period of intense rain yesterday in Atlanta, an unoccupied Waymo vehicle encountered a flooded road and stopped.
Expansion of Service Suspensions
In addition to Atlanta, Waymo has also halted operations in San Antonio, Dallas, and Houston. The company cited severe weather conditions across Texas as the primary reason for these suspensions. A Waymo spokesperson noted that the decision was made out of an abundance of caution, considering the forecasted severe weather in these regions.
Software Recall and Ongoing Challenges
Prior to these incidents, Waymo had issued a software recall to address its vehicles’ performance in flooded conditions. The recall involved deploying an update that imposed restrictions in areas with a heightened risk of encountering flooded, high-speed roadways. However, the recent events in Atlanta indicate that these measures were insufficient. Waymo acknowledged that the storm produced rapid flooding before the National Weather Service could issue warnings, highlighting the unpredictability of such weather events.
Regulatory Oversight
The National Highway Traffic Safety Administration (NHTSA) is aware of the Atlanta incident and is in communication with Waymo. A spokesperson for the NHTSA stated that the agency would take appropriate action if necessary. This incident adds to the scrutiny Waymo faces, as the company is currently under investigation for other operational challenges, including issues related to school bus safety and a collision involving a pedestrian.
Historical Context
This is not the first time Waymo has encountered operational difficulties. In December 2025, the company suspended its robotaxi service in San Francisco after a massive blackout left many of its vehicles stalled on city streets. The blackout affected traffic lights and mass transit, causing gridlock throughout the city. Waymo resumed service after implementing software updates to better handle such scenarios.
Future Outlook
Waymo’s recent service suspensions underscore the complexities of deploying autonomous vehicles in diverse and unpredictable environments. The company is actively working on software enhancements to improve its vehicles’ ability to detect and respond to flooded roads and other adverse conditions. As Waymo continues to refine its technology, it remains committed to ensuring the safety of its passengers and the communities it serves.
