Policy & regulation
Regulatory Compliance for Self-Driving Cars
Regulatory compliance is the set of laws, permits and safety rules a self-driving car must meet to test or operate on public roads. There is no single global standard. In the United States it is largely a state-by-state patchwork, layered on top of federal vehicle safety rules, and it differs again across Europe and Asia.
Where did self-driving regulation begin?
In June 2011 Nevada became the first place in the world to pass a law for autonomous vehicles. Assembly Bill 511 directed the state motor vehicle agency to write rules for testing and operating self-driving cars, and in 2012 Nevada issued the first testing license, to Google.
Other states followed quickly, including California, Florida and Michigan, each with its own rules. That early head start is why so much testing clustered in a few states.
Who regulates self-driving cars?
In the United States the job is split. The federal regulator, NHTSA, sets the safety standards the vehicle itself must meet and issues guidance. The states control licensing, testing permits, where driverless operation is allowed, and insurance. There is still no comprehensive federal self-driving law.
Outside the United States the picture differs again. International bodies such as UNECE set shared vehicle rules, the European Union has its own framework, and individual countries add their own road laws and approvals.
Does a self-driving car still have to meet car safety standards?
Yes. A self-driving car is still a motor vehicle, so in the United States it must meet the Federal Motor Vehicle Safety Standards, or FMVSS, set by NHTSA. The country uses self-certification: NHTSA does not approve a vehicle before it is sold. The manufacturer certifies that it meets every applicable standard, and NHTSA can test it, investigate and order recalls afterward.
The standards were written for cars with a human driver. Many assume a steering wheel, brake and accelerator pedals, mirrors and a driver's seat. In 2016, NHTSA told Google it would treat the self-driving system as the driver in its design, but that many standards would still need rule changes or an exemption before a car without manual controls could be sold. A 2022 rule updated the crash-protection standards for such vehicles. The standards for braking, lighting, wipers and other equipment are still being modernized, with proposals published in 2026.
Until those rules change, a vehicle with no steering wheel or pedals generally needs an exemption from NHTSA. The main route, a Part 555 exemption, is capped by law at 2,500 vehicles per manufacturer per year, usually for two years. Bills in Congress in 2026 would raise that cap, but none has become law. Robotaxis built on conventional cars, which keep their steering wheel and pedals, do not face this hurdle.
| Year | Vehicle | What happened |
|---|---|---|
| 2020 | Nuro R2 delivery vehicle | First NHTSA exemption for a driverless vehicle, covering mirrors, windshield and backup camera rules; goods only, no passengers |
| 2022 | Cruise Origin | GM requested an exemption; NHTSA never decided it, and GM shelved the vehicle in 2024, citing regulatory uncertainty |
| 2025 | Zoox robotaxi | Demonstration exemption after a two-year NHTSA review of Zoox's self-certification; rides allowed, but no fares |
| 2026 | Zoox robotaxi | First commercial exemption for a purpose-built robotaxi (July), allowing paid rides |
| 2026 | Tesla Cybercab | Self-certified by Tesla; NHTSA opened an audit of that certification the day rides began (September) |
What does a company have to comply with?
Compliance is layered. A developer must satisfy rules about the vehicle, about how and where it may drive, and about what it must report when something goes wrong.
| Layer | Who sets it | What it covers |
|---|---|---|
| Vehicle safety | NHTSA (federal) | The car's equipment and crashworthiness, under the FMVSS, or an exemption from them |
| Testing and operation | State agencies | Permits to test and to run driverless on public roads |
| Crash and data reporting | State and federal | Mandatory reporting of collisions and disengagements |
| International | UNECE and national rules | Vehicle approval and road rules outside the United States |
Why is regulation so fragmented?
The technology moved faster than the law, so rules grew up one jurisdiction at a time rather than from a single plan. Hard questions about safety evidence, liability after a crash, and public trust are still being worked out.
The result shapes the product. Because approval is local, operators confine their cars to the cities and conditions where they are permitted, which is one reason a robotaxi service exists in one metro area but not the next.

Frequently asked
- Which was the first state to legalize self-driving cars?
- Nevada. In June 2011 it passed Assembly Bill 511, the first law in the world for autonomous vehicles, and in 2012 it issued the first testing license, to Google.
- Is there a federal self-driving car law in the United States?
- There is no comprehensive federal self-driving law. NHTSA sets the safety standards for the vehicle and issues guidance, while individual states regulate testing, driverless operation, licensing and insurance.
- Who regulates self-driving cars?
- In the United States, NHTSA regulates the vehicle's safety and the states regulate testing and operation. Internationally, bodies such as UNECE and each national government set their own rules.
- Do robotaxis need approval in each city?
- In the United States, largely yes. State agencies decide where driverless vehicles may test and carry passengers; California, for example, requires permits from both its DMV and its public utilities commission. So operators seek approval market by market.
- Can a car without a steering wheel be sold in the United States?
- Only with care. Federal safety standards assume manual controls, so such a vehicle generally needs an NHTSA exemption, capped at 2,500 vehicles a year per manufacturer, unless its maker can certify it meets every standard, which NHTSA may then audit.
