AV Emergency Response Coordination Act: Robotaxi Safety Bill

A series of high-profile traffic meltdowns in San Francisco has finally pushed Washington to act. Representative Kevin Mullin of California introduced the AV Emergency Response Coordination Act on July 28, a bill that would, for the first time, give the federal government authority to set nationwide standards for how autonomous vehicles handle emergencies, from blocking fire engines to driving through active crime scenes.

The legislation directs the National Highway Traffic Safety Administration to establish minimum safety protocols that every autonomous vehicle operator must follow. Among the requirements: a 24/7 emergency hotline staffed by the AV company, standardized response procedures for first responders, and geofencing technology that can keep robotaxis out of active emergency zones. The bill targets the kinds of failures that have become routine in San Francisco, where Waymo vehicles have obstructed emergency responders 31 times since April 2025 alone.

San Francisco Mayor Daniel Lurie appeared alongside Mullin at Fire Station 4 in Mission Bay to voice support for the measure, a notable shift for a city that has long embraced autonomous vehicles with minimal restrictions. Lurie and local authorities do not have the power to regulate the autonomous fleet directly, leaving them reliant on state and federal action.

What Triggered the AV Emergency Response Coordination Act

The most dramatic incident came during July 4 festivities this year, when dozens of Waymo vehicles came to a complete stop and blocked traffic across San Francisco, creating gridlock that trapped emergency vehicles. But that was far from an isolated event. Autonomous vehicles have also driven into active emergency scenes, failed during power outages, and contributed to large-scale traffic jams. The pattern prompted NHTSA Administrator Jonathan Morrison to issue a directive on July 8 warning AV developers that the agency had identified a clear pattern of driverless vehicles interfering with law enforcement and first responders. Morrison gave companies until the end of July to present solutions.

The AV Emergency Response Coordination Act, if passed, would go further than a warning letter. It would codify specific requirements into federal regulation, creating a national template that every AV operator, including Waymo, Cruise, Zoox, and Tesla, would have to follow. The legislation has already drawn support from San Francisco city leadership and highway safety advocacy groups, and Mullin has expressed confidence it will draw bipartisan support in Washington.

The Limits of Local and State Authority

San Francisco finds itself in an awkward position. The city welcomed autonomous vehicles with few initial restrictions, but the operational reality has forced a recalculation. Local officials have limited tools: they cannot directly regulate a fleet operated under state and federal permissions. That gap has pushed the city to explore a local fining system. A draft proposal at City Hall would give San Francisco agencies the authority to issue administrative penalties when autonomous vehicles block emergency responses. Supervisor Connie Chan has backed legislation that would impose financial consequences on AV companies for blocking emergency routes.

At the state level, California Senator Dave Cortese introduced SB 1246 in February, a bill that would fine AV companies up to $10,000 for blocking first responders. That measure would require companies to immediately dispatch a technician to move a stalled vehicle or allow first responders to move it themselves. For robotaxis without manual controls, the company would bear full responsibility for any obstruction.

These overlapping efforts, local fines, a state bill, and now a federal proposal, illustrate a broader shift. The regulatory center of gravity for autonomous vehicles is moving from the California Public Utilities Commission in San Francisco to Capitol Hill in Washington. The AV Emergency Response Coordination Act is the first major federal legislative attempt to regulate how robotaxis behave in emergencies, and if it passes, it could preempt or supersede many of the patchwork local and state rules currently being drafted.

What the AV Emergency Response Coordination Act Requires

The core of the legislation breaks down into three operational mandates. First, every AV operator must maintain a 24/7 emergency hotline that first responders can call to reach a human operator who can remotely direct or disable specific vehicles. Second, operators must develop and share standardized response protocols with local police and fire departments so that emergency crews know exactly how to interact with the vehicles, how to move them, how to shut them down, and whom to contact. Third, the vehicles themselves must have geofencing capabilities that allow operators to exclude them from active emergency zones, preventing the kind of autonomous drift into active scenes that NHTSA documented in its July 8 letter.

The bill directs NHTSA to establish these minimum safety standards, meaning the agency would define the technical specifics through its rulemaking process. That approach gives regulators flexibility to adapt requirements as the technology evolves rather than locking specific engineering choices into statute. But it also means that even if the bill passes quickly, the actual standards could take months or longer to develop.

For Waymo and other AV operators, the stakes are existential in a practical sense. The industry has scaled its deployments faster than its technology has proven it can handle unpredictable real-world emergencies. NHTSA has already stated bluntly that emergency scenes are not edge cases but foreseeable operating conditions that every autonomous system must handle. The AV Emergency Response Coordination Act would turn that expectation into binding federal law.

The financial implications are also significant. California SB 1246 proposes fines of up to $10,000 per incident for blocking first responders. With 31 documented Waymo obstructions since April 2025, and likely more unreported cases, the aggregate liability under such a regime would run into the hundreds of thousands of dollars, with further escalation if the pattern continues. Federal standards could introduce even steeper penalties or operational restrictions, including potential suspension of deployment permits for noncompliant operators.

The broader competitive picture adds another dimension. Uber and Waymo are already engaged in a political contest over the regulatory framework for robotaxis in Washington D.C. The AV Emergency Response Coordination Act could reshape that contest by establishing a uniform national floor for emergency response, potentially advantaging operators who have already invested in remote-assist infrastructure over those who have not.

Why this matters

This bill is the moment when robotaxi regulation shifts from a local and state patchwork to a federal framework. For autonomous vehicle operators, the era of relatively unchecked urban deployment is ending. The requirement for 24/7 emergency hotlines, geofencing, and standardized responder protocols will impose real operational costs and engineering demands. For cities like San Francisco that have watched robotaxis disrupt emergency response with no recourse, the legislation offers a pathway to accountability. And for the broader autonomous vehicle industry, the message is clear: the technology must prove it can coexist with emergency services, or regulators will force the issue.
