Rep. Kevin Mullin (D-California ) has proposed a bill that would direct federal regulators to establish minimum national safety standards for autonomous vehicle operators.

Waymo and other robotaxi operators are facing increased scrutiny — and possible new federal requirements — over how their autonomous vehicles interact with emergency responders, a regulatory risk that’s becoming harder for the industry to shrug off. Rep. Kevin Mullin (D-Calif.) is the latest lawmaker to put pressure on the industry with a proposed bill that would direct federal regulators to establish minimum national safety standards for autonomous vehicle operators. The proposed legislation, expected to be introduced in Congress this week, follows a number of incidents in which autonomous vehicles have blocked ambulances and fire trucks, driven into active crime scenes, and failed to recognize safety signals such as traffic cones and flares. A TechCrunch investigation earlier this year identified a number of incidents in which Waymo relied on first responders to manually drive its vehicles when they encountered issues. The legislation, called the AV Emergency Response Coordination Act, was unveiled Tuesday during a press conference in San Francisco, a hub of autonomous vehicle testing and where hundreds of Waymo robotaxis already give rides to paying customers. San Francisco mayor Daniel Lurie, San Francisco fire chief Dean Crispen, and Advocates for Highway and Auto Safety president Cathy Chase also spoke at the press conference. “We have seen disturbing, and frankly, an unacceptable number of incidents where autonomous vehicles inadvertently interfere with emergency responders,” Mullin said during the press conference. Crispen said that while the fire department has worked with AV operators, a number of incidents, and a pattern of continued behavior, shows changes need to be made. He noted that robotaxis are picking up and dropping off passengers directly in front of fire stations and ambulance deployment facilities, which obstructs emergency access. Mullin’s bill proposes requiring AV companies to provide clear emergency protocols for first responders, establish a 24-hour hotline that gives public officials direct access to these companies, and directs the National Highway Traffic Safety Administration (NHTSA) to develop minimum national emergency response standards. The bill would also create a process allowing public officials to “geofence” AVs, a term referring to placing limits on where these vehicles can operate during emergencies or other ongoing safety hazards. For AV operators, that geofencing provision could matter as much as the safety standards themselves: It would give city and public safety officials a real-time lever to restrict where robotaxis can drive, rather than waiting on companies to self-regulate.
