National Highway Traffic Safety Administration (NHTSA) Administrator Jonathan Morrison issued a directive Wednesday to autonomous vehicle (AV) developers, stating that it is unacceptable for their vehicles to interfere with first responders or law enforcement.

Morrison noted in the letter that the agency has “identified a clear pattern of driverless AVs interfering with law enforcement and other first responders,” citing instances in which these vehicles drove into active emergency scenes, blocked the paths of ambulances and firefighters, or failed to recognize and respond to basic safety conditions like flashing lights, flares, smoke, fire, and traffic cones.

The agency has demanded that AV developers present their “solutions” to this problem by the end of the month.

“Let me be clear: the inability to detect and appropriately respond to such situations represents a functional insufficiency,” Morrison’s letter reads. “Emergency scenes are not rare or extreme ‘edge cases.’ As such, NHTSA is today issuing a call to action for AV developers and operators to immediately focus their resources on fixing this issue.”

The agency doesn’t explicitly call out any particular company in the letter; however, the details suggest it is directed at robotaxi operators like Waymo.

TechCrunch has reached out to Waymo for comment and will update the article once the company responds.

A previous TechCrunch investigation found that Waymo — which operates the largest robotaxi fleet in the United States, with vehicles in cities including Los Angeles, Phoenix, and San Francisco — has had repeated run-ins with first responders. In at least six incidents identified by TechCrunch through March of this year, first responders had to take control of Waymo vehicles and move them out of traffic during emergency situations. In one instance, an officer was in the middle of responding to a mass shooting. In June, an officer was recorded moving a Waymo to unblock a roadway for first responders headed to a natural gas explosion at an apartment building.

The agency’s letter to AV developers doesn’t say what the consequences would be if the request is ignored. Nor does it outline what the acceptable solutions would be. But the agency does imply it would hold companies accountable, just as it does human drivers who impede law enforcement.

“Every second matters when law enforcement officers, firefighters, or paramedics are answering a call because lives are on the line,” the letter states. “That is why human drivers who impede these operations are subject to fines and even jail time.”

The agency also noted in a press release accompanying the letter that it’s making progress on updating Federal Motor Vehicle Safety Standards (FMVSS) requirements, which govern vehicle design and equipment requirements. These proposed changes could help autonomous vehicle companies like Tesla and Zoox, which are developing vehicles without steering wheels, pedals, or other features required on human-driven cars. The agency has already proposed rules that would eliminate the need for windshield wipers, sun visors, defogging systems, and tire placards. The agency released a new 2026 Regulatory Plan and Unified Agenda last week, outlining its proposals.
