U.S. proposes national safety law for robotaxis

What happened?

On July 28, 2026, Representative Kevin Mullin (D-California) introduced a bill that would direct federal regulators—such as the National Highway Traffic Safety Administration (NHTSA)—to establish national minimum safety standards for autonomous vehicle operators, according to TechCrunch. The proposal comes after multiple documented incidents: Waymo and Cruise robotaxis that blocked ambulances, disrupted firefighting operations, and left passengers stranded in traffic. In San Francisco, a Cruise robotaxi dragged a pedestrian for 20 feet in October 2023, leading to the suspension of its commercial operations by the California Department of Motor Vehicles. These events have eroded public trust and highlighted the absence of a coherent federal framework.

Historically, autonomous vehicle regulation in the U.S. has been a patchwork of state and local rules. California and Arizona have been pioneers, but with divergent approaches: California requires permits and detailed reporting, while Arizona has been more lenient. The NHTSA has issued voluntary guidelines but lacks the authority to impose binding standards. This bill, formally titled the “Autonomous Vehicle Safety Standards Act,” seeks to fill that gap by establishing mandatory federal requirements for the first time.

Why is it important?

The importance of this law lies in unifying criteria at the national level, eliminating the regulatory fragmentation that has allowed companies like Waymo and Cruise to operate with different levels of oversight depending on the city or state. Currently, a robotaxi can be approved in San Francisco but banned in Los Angeles, creating uncertainty for operators and risks for the public. Federal law would end this disparity by setting a common safety floor.

Furthermore, it is an explicit recognition that autonomous technology cannot be fully self-regulated. The industry has promoted voluntary self-regulation, but recurring incidents show that economic incentives do not always align innovation with public safety. This bill reflects a paradigm shift: from trusting companies' good faith to imposing clear and enforceable rules. As Mullin stated in his announcement: “This law is a necessary step to ensure that innovation does not compromise public safety.”

The measure also comes amid growing scrutiny. The NHTSA has opened several investigations into robotaxi incidents, including collisions with pedestrians and cyclists. In 2024, the agency reported more than 200 crashes involving autonomous vehicles in California, 40% of which required human intervention. These data underscore the urgency of federal regulation.

Consequences for the industry

If passed, operators like Waymo (Alphabet), Cruise (General Motors), and Zoox (Amazon) would need to redesign their systems to comply with federal requirements. This could involve modifications to software, hardware, and operational protocols, delaying deployments and increasing costs. For example, Waymo has invested billions in its technology, and additional adjustments could add hundreds of millions. Cruise, which already faces financial difficulties after the 2023 incident, could see its expansion plan to 15 cities stalled.

The law could also affect expansion strategies into new cities. Currently, companies prefer to launch in markets with lax regulations; with uniform federal standards, the advantage of cities like Phoenix or Austin would diminish. In the long term, however, standardization could build public trust, accelerating adoption. A 2025 J.D. Power study showed that 68% of Americans distrust robotaxis, but that percentage drops to 45% when strict federal regulations are mentioned.

Opposition will not be long in coming. Groups like the Autonomous Vehicle Industry Association (AVIA) will argue that premature regulation stifles innovation and that standards should be flexible to adapt to rapid technological evolution. They will also point out that incidents are rare compared to accidents caused by human drivers (more than 40,000 deaths annually in the U.S.). However, the bill has the support of road safety organizations like Advocates for Highway and Auto Safety, which see it as a necessary step forward.

What readers should know

• The bill still must pass through committees (likely the House Energy and Commerce Committee) and then be voted on in the House and Senate. Its passage is not certain, especially in an election year where the issue could become polarized.
• Opposition from pro-innovation sectors is expected to argue that premature regulation hampers technological development and that federal standards could be too rigid for an evolving technology.
• Standards could include: requirements for communication with emergency services (e.g., ability to receive signals from emergency vehicles and yield), capability to be manually towed (many current robotaxis lack steering wheels or pedals), protocols to avoid obstructions (such as stopping in the middle of the street), and backup systems for software or sensor failures.
• The measure adds to NHTSA investigations into robotaxi incidents, including the probe into Cruise accidents that began in 2023 and is still open.

“This law is a necessary step to ensure that innovation does not compromise public safety,” Mullin said in the official statement.

In summary, Mullin's bill represents a milestone in autonomous vehicle regulation in the U.S., moving from a fragmented approach to a federal one. Although it faces political and industry obstacles, its mere introduction indicates that the era of self-regulation is over. For companies, the message is clear: safety must be integrated from the design stage, not as an afterthought. For the public, it is a sign that regulators are taking their concerns seriously. The debate is just beginning, and its outcome will shape the future of autonomous mobility in the country.
