The National Highway Traffic Safety Administration (NHTSA) documented a pattern of autonomous vehicles blocking ambulances, fire trucks, and police cruisers, and on July 8, 2026 demanded that companies present solutions before the end of the month. Jonathan Morrison, the agency's administrator, stated that these vehicles' inability to detect emergency scenes poses a danger to the public.

Morrison's letter, reported by Wired and TechCrunch, rejects the framing that emergency scenes are rare edge cases. The official detailed that vehicles have entered active emergency zones, blocked the path of ambulances and fire trucks, and failed to respond to flashing lights, flares, smoke, or traffic cones.

According to a TechCrunch investigation, at least six incidents were documented through March 2026 in which emergency personnel had to physically take control of Waymo vehicles to move them during an emergency. The company operates robotaxi fleets in Los Angeles, Phoenix, San Francisco, Austin, and Dallas, cities with a significant Latino community presence.

The incidents include a case from late May in Dallas, where a Waymo partially blocked a fire truck's access to a burning building, as reported by Wired. In March, in Austin, a vehicle from the same company blocked an ambulance for two minutes as it responded to a mass shooting that left three people dead and at least 14 injured.

In San Francisco, the fire department chief reported that Waymos frequently block access to stations. An Austin police representative told Wired that the technology was deployed too quickly and in excessive numbers. NHTSA had already issued corrective recalls for Waymo over failures in flooded and construction zones, and for Zoox for stopping in oncoming traffic.

The agency warned that it will exercise its enforcement authority against companies that fail to address these issues. The order arrives as discussions about the potential arrival of autonomous vehicles in Mexico advance in the transportation sector, making the U.S. experience a regulatory reference point for the region.
