Waymo has temporarily stopped allowing its fully driverless vehicles to use freeways in Phoenix as the company works to improve how the autonomous cars handle difficult roadway conditions, particularly construction zones and other unpredictable driving environments.
The company confirmed the pause affects fully autonomous freeway rides in Phoenix along with several other Waymo markets across the country, including San Francisco, Los Angeles, Miami, and additional cities where the company operates driverless ride-hailing services.
Waymo said the temporary suspension is connected to ongoing software updates and safety improvements involving the company’s autonomous driving system. Company officials explained they are reevaluating how the vehicles respond in construction zones and other complicated traffic scenarios that can rapidly change and create challenges for self-driving technology.
Despite the freeway pause, Waymo emphasized that its robotaxi service on regular city streets throughout Phoenix remains fully operational. Customers can still request rides through the Waymo One app across the company’s Metro Phoenix service territory, though trips that previously used freeway routes may now take longer because vehicles are limited to surface streets.
The freeway suspension comes after a series of incidents and growing scrutiny involving Waymo vehicles in recent months. Earlier this year, a Waymo passenger in Phoenix reportedly fled a vehicle after it drove onto light rail tracks and stopped near an approaching train. Viral videos of the incident sparked renewed debate over autonomous vehicle safety in Arizona.
Waymo has also faced additional safety concerns outside Arizona. Reuters reported the company recently recalled approximately 3,800 autonomous vehicles after identifying problems involving flooded roads and difficult roadway conditions. The company has since been updating software intended to improve vehicle behavior in those situations.
According to reports, Waymo additionally paused operations in Atlanta and parts of Texas because of severe weather and flash flooding concerns. In one incident, a Waymo vehicle reportedly became stranded in floodwaters in San Antonio, increasing pressure on the company to strengthen its systems for handling dangerous weather and roadway hazards.
Waymo began expanding freeway operations in Phoenix in late 2025, allowing its autonomous Jaguar I-PACE vehicles to operate at higher speeds on Valley freeways. The expansion marked a major milestone for the company because freeway driving presents significantly more complex challenges than city street navigation due to higher speeds, merging traffic, construction activity, and rapidly changing traffic patterns.
Phoenix remains one of Waymo’s largest and most established markets. The company launched its public autonomous ride-hailing service in the Valley years before expanding into cities such as San Francisco, Los Angeles, Miami, Atlanta, and Austin.
Waymo, which operates under Alphabet Inc., has increasingly become one of the leaders in the autonomous vehicle industry. The company says its self-driving system has logged more than 200 million autonomous miles across public roads in the United States.
However, the company continues facing public scrutiny and federal attention as autonomous vehicle technology expands. Multiple investigations involving Waymo vehicles have emerged nationwide over issues such as blocked emergency vehicles, school bus incidents, traffic disruptions, railroad track mistakes, and roadway navigation errors.
Transportation experts say freeway driving remains one of the most difficult challenges for autonomous vehicle systems because self-driving software must rapidly interpret high-speed traffic conditions, lane changes, construction detours, emergency situations, and aggressive driver behavior in real time.
Waymo has not announced a specific timeline for when freeway service in Phoenix will resume. The company said it plans to continue testing and refining its autonomous driving software before restoring freeway operations for passengers.
Phoenix has become one of the nation’s largest testing grounds for autonomous vehicle technology because of its relatively predictable weather, wide roadways, and supportive regulatory environment. Driverless vehicles from Waymo are now a common sight throughout many parts of the Valley.
