For decades, the Federal Motor Vehicle Safety Standards (FMVSS) have been the rulebook for everything from seatbelts to headlights. But when those rules were inked, the idea of a car piloting itself without a steering wheel—or even a driver—was strictly the stuff of science fiction. Today, with autonomous shuttles already roaming certain city streets, the government is finally working to catch the law up to the tech.
The National Highway Traffic Safety Administration (NHTSA) has proposed a slate of changes aimed at making those aging regulations compatible with driverless vehicles, particularly robotaxis and purpose-built shuttles like those operated by Amazon-owned Zoox. In their current form, the rules are littered with assumptions about human drivers, from references to transmission shift levers to requirements tied to the driver’s seating position.
Among the four updates on the table: revising standards for transmission shift position sequences, as well as modernizing rules covering windshield defrosting, defogging, and wiper systems. NHTSA also wants to tweak FMVSS 108, the catchall regulation for lights and reflective devices, which currently presumes a human behind the wheel.
The move builds on an earlier effort to simplify the exemption process for companies developing autonomous vehicles. By clearing away outdated driver-centric language, NHTSA hopes to both streamline development and keep individual states from cobbling together their own patchwork rules—a nightmare scenario for automakers trying to scale nationwide fleets of AVs.
“Federal Motor Vehicle Safety Standards were written for vehicles with human drivers and need to be updated for autonomous vehicles,” said NHTSA Chief Counsel Peter Simshauser. “Removing these requirements will reduce costs and enhance safety.”
It’s a statement that captures both the promise and the tension of this moment. Regulators want to “unleash American ingenuity” while ensuring that safety doesn’t take a back seat to speed of deployment. With the rules of the road under revision, the big question is how fast these robotaxis will move from novelty to normal.
