Waymo will resume robotaxi highway routes it had suspended for more than two months. TechCrunch reported on Tuesday that Waymo decided to sequentially add highway routes back to its service areas, starting with Phoenix.

Waymo said in a post on social media platform X that it is gradually restoring highway routes. It said Los Angeles and the San Francisco Bay Area will follow within days after Phoenix.

Waymo said it is restarting highway driving across its entire service area, including construction zones. It applied a software update to improve driving performance around highway construction sites. It also strengthened scene recognition and route-setting functions.

The resumption comes as safety scrutiny has intensified around Waymo and other robotaxi operators. Kevin Mullin (케빈 멀린), a U.S. House lawmaker, introduced a bill this week to direct federal regulators to establish national minimum safety standards for autonomous vehicle operators. Earlier, there were a series of cases in which autonomous vehicles blocked the passage of ambulances and fire trucks or entered crime scenes, and failed to recognize safety signals such as traffic cones and flares.

Waymo began robotaxi services that include highways in San Francisco, Phoenix and Los Angeles in November 2025, and later added highway routes in Miami. It suspended those routes in May to improve performance in handling construction zones.

Waymo later said in a report submitted in June to the U.S. National Highway Traffic Safety Administration that it confirmed at least 13 cases in which robotaxis entered highway sections closed due to construction. The company voluntarily recalled its robotaxi fleet of about 4,000 vehicles and said there were no injuries or collisions related to the issue. After reviewing the incidents, it temporarily restricted highway operations.

The recall was the sixth taken by Waymo. Earlier, Waymo also modified software in cases involving robotaxis entering flooded roads or driving illegally around school buses.
