The US Department of Transportation is rewriting the rulebook for what counts as a car. The agency is moving to eliminate the requirement that vehicles include a brake pedal, a steering wheel, and other traditional human controls, clearing the regulatory path for fully driverless vehicles to hit American roads at scale.

The update targets the Federal Motor Vehicle Safety Standards (FMVSS), the set of rules that has governed vehicle design in the US for decades. Those standards were written with an assumption so obvious nobody questioned it: a human would be driving. That assumption is now officially outdated.

What’s actually changing

The National Highway Traffic Safety Administration (NHTSA), the arm of the DOT responsible for vehicle safety, has been working on updated FMVSS rules designed to accommodate vehicles built around Automated Driving Systems (ADS).

The updated standards are set for approval in March 2026. They would replace conventional safety requirements that mandate things like brake pedals, steering columns, and accelerators with performance-based criteria. Instead of asking “does this car have the right hardware for a human driver,” regulators would ask “does this car’s autonomous system meet equivalent safety benchmarks.”

Transportation Secretary Sean Duffy introduced a broader policy framework in June 2025 aimed at accelerating the process. One key piece: speeding up the Part 555 exemption process, which allows manufacturers to deploy vehicles that don’t meet traditional FMVSS requirements, provided they can demonstrate equivalent safety.

Under the old timeline, getting a Part 555 exemption could take years. The new policy aims to compress that decision window to months. Each manufacturer can receive exemptions for up to 2,500 vehicles per year under this pathway.

The 2025 actions also included amendments to crash reporting protocols and the inclusion of domestic vehicles in the Automated Vehicle Exemption Program, broadening the pool of companies that can participate.

Why this matters beyond the auto industry

For years, autonomous vehicle companies like Waymo and Zoox have been constrained by safety standards written for a world where someone’s foot needs to reach a brake pedal. Building a vehicle without one meant navigating a complex, slow exemption process. The regulatory framework was, in effect, forcing companies to design around a human driver who was never supposed to be there.

The shift to performance-based standards changes the incentive structure entirely. Instead of bolting on legacy hardware to satisfy a checkbox, manufacturers can design vehicles from the ground up for autonomous operation. That opens up new form factors, new interior layouts, and potentially new business models for ride-hailing, delivery, and logistics.

NHTSA has been laying the groundwork for this moment since at least 2020. The agency has been conducting long-term studies evaluating how 81 existing FMVSS apply to ADS-equipped vehicles, covering critical systems like braking and electronic stability control. The March 2026 rule update represents the culmination of that multi-year review.

What this means for investors

With the FMVSS update on track for March 2026 and the accelerated exemption process already underway, companies positioned at the front of the autonomous vehicle race, particularly those with operational driverless fleets or vehicles already in testing, stand to benefit most from faster regulatory throughput.

The 2,500-vehicle-per-manufacturer annual cap on exemptions is worth watching. It’s high enough to enable meaningful commercial deployment but low enough to keep a lid on runaway scaling before safety data catches up.

The broader signal here is a philosophical shift from prescriptive regulation to performance-based regulation. Rather than dictating specific components a vehicle must include, the government is moving toward asking whether the overall system achieves equivalent or better safety outcomes. That approach tends to favor incumbents with deep engineering resources and extensive real-world testing data, while potentially creating higher barriers for smaller startups that lack the infrastructure to demonstrate safety equivalence at scale.

The risk side of the ledger isn’t empty. Performance-based standards are only as good as the metrics used to evaluate them, and NHTSA hasn’t finalized all the testing protocols. A high-profile accident involving a pedalless vehicle could slow the entire program. And the 2,500-unit cap means even under the best scenario, we’re talking about a gradual rollout, not a flood of robotaxis appearing overnight.
