NHTSA audits Tesla Cybercab certification hours after Austin launch
The US road safety regulator has opened an audit into how Tesla certified its Cybercab, the driverless robotaxi it deployed in Austin with no steering wheel and no pedals. The National Highway Traffic Safety Administration announced the inquiry on Friday 4 September, as TechCrunch reported, hours after the first Cybercabs reached public roads.
Automakers traditionally certify their own vehicles against the Federal Motor Vehicle Safety Standards, and Tesla told NHTSA the Cybercab complies with all of them. The agency says it opened the investigation to “examine the process and technical data on which Tesla relied when certifying the Cybercab and related issues.” That’s an audit of the paperwork, not a verdict on how the car drives.
NHTSA fully supports the safe development and deployment of automated vehicles. But as the federal regulator, we need to ensure that all of our laws are followed.

Nothing has been ordered off the road. NHTSA hasn’t commented on the Cybercab’s safety or compliance, Business Insider reported, and the announcement doesn’t halt deployments. Texas DMV records list 45 Cybercabs registered to Tesla, and the vehicle still isn’t available for consumers to buy.
The difficulty is that the Cybercab lacks conventional human controls such as a steering wheel, pedals and side mirrors, which current federal standards require. So the audit turns on a legal question rather than an engineering one. NHTSA will look at whether Tesla was correct to decide that some of those requirements simply don’t apply to a vehicle no human drives.
There’s a recent precedent, and it points the other way. Zoox, owned by Amazon, self-certified its own steering-wheel-free robotaxi in 2022, drew a special order and an audit query from NHTSA, then went through the formal exemption process instead. That exemption was granted on 31 July 2026 and runs to 31 July 2028.
Reading the grant notice shows what Tesla is choosing to skip. NHTSA exempted the Zoox sedan from parts of eight standards, covering defrosting, wipers, lamps, rear visibility, brakes, interior impact, glazing and crash protection. The notice caps Zoox at 2,500 exempted vehicles introduced into commerce in any 12 month period, a limit written into the Safety Act itself.
| Two routes to a pedal-free robotaxi | Zoox | Tesla Cybercab |
|---|---|---|
| Mechanism | Part 555 temporary exemption | Self-certification |
| Standards position | Exempt from parts of 8 FMVSS | Certified compliant with all FMVSS |
| NHTSA action | Exemption granted 31 July 2026 | Audit announced 4 September 2026 |
| Volume cap | 2,500 vehicles per 12 months | None stated; 45 registered in Texas |
| Oversight after launch | Operational Authorizations from NHTSA | Not applicable |
Tesla’s bet is that the rules are about to change anyway. NHTSA has been rewriting the standards that assume a human behind the wheel, and in June it proposed modernising FMVSS No. 135, the light vehicle brake systems standard. The proposal says driverless vehicles face barriers from requirements such as a foot-operated service brake pedal, “which is unnecessary for operation of the vehicle by the ADS.” Stopping distance requirements would still apply to all subject vehicles.
That rewrite isn’t finished. Comments on the brake standard closed on 27 July 2026, and NHTSA said on Friday it wants to remove unnecessary barriers to American AV innovation in the coming months. In the same statement the agency added that “until that work is completed, however, existing standards remain in force.” Timing, in other words, is the whole story.
Tesla certified itself compliant with rules the regulator is still in the middle of rewriting.

Zoox self-certified in 2022 and only opened its commercial service this year, and it now charges for rides in Las Vegas. Whether Tesla faces a similarly long process is unclear, though the company has already drawn regulatory attention elsewhere in 2026, including a 3 million vehicle recall in China. Regulators have been sharpening their approach to automated systems more generally, which is how Uber came to be hit with an 825 million euro fine over automated driver deactivations.
What’s worth watching is which finishes first: the audit, or the rulemaking that would make the audit moot. Tesla didn’t immediately respond to a request for comment from Business Insider.
