Waymo Recalls 3,871 Robotaxis Over Construction Zone Hazard
Original: Waymo Recalls Robotaxis Over Risk They'll Drive at Speed Into Freeway Construction Zones
Why This Matters
Repeated safety recalls underscore challenges autonomous vehicle developers face in highway operations and construction zone detection.
Waymo filed its fourth safety recall with NHTSA on June 17, 2024, affecting 3,871 vehicles. The company's autonomous cars entered closed freeway construction zones at highway speeds due to faulty hazard prioritization logic. No collisions or injuries were reported.
Waymo has issued its fourth safety recall since February 2024, this time covering 3,871 vehicles equipped with its 5th Generation automated driving system (ADS). The National Highway Traffic Safety Administration (NHTSA) filing, submitted June 17, 2024, identifies a defect where autonomous vehicles may enter and drive at speed through freeway construction zones under certain circumstances. The fault stems from two issues: the ADS sometimes fails to recognize construction zones entirely, and in other cases actively prioritizes avoiding other freeway hazards while ignoring construction zones. Incidents began in April 2024 in Phoenix, where vehicles drove past ramp closure signs into pre-planned construction zones on April 11 and 19. A second cluster occurred May 18 in the San Francisco Bay Area, when seven Waymo vehicles drove between construction cones into active lane closures. Though no collisions or injuries resulted, these incidents prompted Waymo to restrict freeway operations company-wide. The company's Safety Board reviewed the issue June 1 and authorized a formal recall June 8. Waymo stated it has voluntarily restricted all freeway operations while developing a permanent software fix, which the NHTSA filing notes is currently under development. The company will deploy the fix via over-the-air software updates once completed. This represents a significant operational restriction, as Waymo previously offered freeway services in San Francisco, Los Angeles, Phoenix, and Miami.
