A California congressman has introduced legislation that would require federal regulators to create minimum safety standards for autonomous vehicles, directly challenging the current patchwork of state rules and responding to growing concerns about robotaxi emergency response failures.

What You Need to Know

The bill, proposed by Rep. Kevin Mullin (D-California), targets the lack of national safety benchmarks for self-driving cars. Incidents involving Waymo vehicles have highlighted problems with how robotaxis handle emergencies such as fire trucks and police stops. The legislation would give the National Highway Traffic Safety Administration two years to develop rules. If passed, the measure could slow or alter the deployment of autonomous vehicle fleets across the U.S.

The Legislative Response to Robotaxi Incidents

Rep. Kevin Mullin's proposed bill would direct the National Highway Traffic Safety Administration to establish minimum federal safety standards for autonomous vehicle operators. The move comes after multiple reports of Waymo vehicles failing to properly respond to emergency situations, including blocking fire trucks and creating hazardous conditions during police stops. Current regulations vary widely by state, with no unified national framework governing how self-driving cars should behave in crises.

The legislation addresses a critical gap in oversight. While the Department of Transportation has issued voluntary guidelines, no binding federal rules exist for autonomous vehicle safety. Mullin's bill would change that by requiring NHTSA to create standards within two years, covering everything from emergency vehicle detection to communication protocols with first responders.

Industry and Regulatory Pushback

Autonomous vehicle operators, including Waymo, have largely opposed federal mandates, arguing that state-level testing provides sufficient oversight. Industry groups contend that rigid national standards could stifle innovation and slow the rollout of safety-enhancing technology. Mullin, however, views the current approach as dangerously fragmented.

“We cannot have a situation where a robotaxi in California behaves completely differently from one in Texas when an ambulance approaches,” Mullin said in a statement. The bill has drawn support from consumer safety advocates and some local governments who have struggled to manage autonomous vehicle deployments without clear federal guidance.

  • National standards: NHTSA must create minimum safety rules within two years.
  • Emergency response: Rules would mandate how robotaxis detect and yield to emergency vehicles.
  • Data reporting: Operators would be required to report incidents involving emergency responders.

Why This Matters

The bill represents a turning point in the autonomous vehicle debate. Without federal standards, companies like Waymo have expanded operations under varying state rules, creating confusion for first responders and inconsistent safety outcomes. If enacted, the legislation would force operators to meet a uniform baseline, potentially delaying new deployments as companies retrofit vehicles to comply. The real-world impact extends beyond industry timelines. For cities and emergency services, clear federal rules could reduce the risk of robotaxis interfering with critical response operations, improving public safety. The bill also signals that Congress is willing to intervene in AV regulation, a domain previously left to states and voluntary industry efforts. This could accelerate broader federal oversight of artificial intelligence in transportation.

What Comes Next

The bill now heads to committee, where it faces strong opposition from autonomous vehicle lobbyists and some lawmakers who favor a lighter regulatory touch. Mullin has indicated he will push for hearings later this year, aiming to build bipartisan support. The outcome will affect every company operating self-driving cars in the United States, with Waymo standing as the most visible test case for the new rules. If the bill passes, it could reshape the competitive landscape, favoring operators who can quickly adapt to national standards while slowing those reliant on state-level leniency.
