NHTSA has moved from asking Tesla a question to compelling an answer. On 10 September 2026 the agency issued a formal Special Order requiring Tesla to explain, under oath, how a car with no steering wheel, no pedals and no mirrors complies with federal safety standards written on the assumption that all three exist. Tesla has until 30 September to respond.
What changed since the audit query
A week earlier, NHTSA opened Audit Query AQ26002 into the Cybercab's certification paperwork on the day paid rides began in Austin, covering an estimated 1,000 vehicles. That was a request. A Special Order is a legal instrument: it sets a deadline, it compels sworn answers, and failing to answer is itself a violation independent of what the answers reveal.
The exposure makes the difference concrete. Under 49 U.S.C. § 30166 — the section authorising the agency to demand information — penalties run to $27,874 per violation per day, capped at $139,356,994 for a related series of daily violations. That is the origin of the $139 million figure, and it attaches to the answering, not to the car.
The six standards NHTSA named
| FMVSS | Subject |
|---|---|
| 101 | Controls and telltales |
| 102 | Shift-position display |
| 108 | Turn signals |
| 111 | Mirrors and rearview images |
| 126 | Stability-control telltales |
| 135 | Foot-activated service brake |
Every one regulates a part, a display or a warning that assumes somebody is sitting in a driver's seat looking at it. Tesla's position, as NHTSA described it in the audit query, is that where the part is absent the standard has nothing to govern.
NHTSA's counter is narrower than a general objection. The agency pointed to its own published position that a manufacturer of a vehicle without a foot-activated service brake could not certify to that standard — not that it would fail the test, but that the certification is unavailable. It also quoted the statute on false certification: a person may not issue one "if, in exercising reasonable care, the person has reason to know the certificate is false or misleading in a material respect."
Why the sworn part matters
Self-certification is an honour system with an audit at the end. There is no pre-market type-approval in the United States, so Tesla attached its own compliance label and began selling, and everything the agency does afterwards rests on what the manufacturer tells it. Hence an instrument carrying a signature under penalty of perjury. NHTSA used the same pairing with Zoox, and that matter ran for years.
What it means, and what it does not
It does not mean the Cybercab has been found unsafe. No crash, injury or complaint prompted this, the cars are still carrying passengers, and NHTSA has not asked Tesla to stop. The risk is the paperwork route to a recall: a vehicle failing an applicable standard is recallable whether or not it has ever misbehaved.
Why Europe cannot run this experiment
For European readers this stays a spectator sport, deliberately. A driverless vehicle here needs approval before sale under the EU's automated driving framework, so the question Tesla is answering under oath is one a type-approval authority would have asked before the first passenger got in. That is why the Cybercab is in Austin, why Musk will not put a date on Europe, and why the joystick Tesla uses to drive the car by hand is more interesting than it looks: FMVSS 135 governs a pedal, and Tesla's fallback control is neither a pedal nor in the car.
One note on sourcing. The Special Order has not appeared in NHTSA's public investigation file, which still holds only the 3 September audit query resume. Its existence, date, deadline and list of standards come from Electrek's reporting; the penalty figures are from the statute and can be checked independently.
Update: 2026-09-19
NHTSA has since published the Special Order itself, settling the sourcing caveat above: it is now in the AQ26002 file as INIM-AQ26002-17090P1, dated 10 September 2026 and signed by Chief Counsel Peter Simshauser. The primary document confirms the 30 September deadline, the standards named and the $139,356,994 cap, and adds three things.
The order runs to 21 numbered requests. Falsifying or withholding information carries criminal exposure — a fine or imprisonment of up to 15 years under 49 U.S.C. § 30170(a)(1) — separately from the civil penalties. Requests 5 to 7 press on temporarily attached human controls: whether the Cybercab can be driven with them, whether they formed part of Tesla's certification basis, and if so how their removal squares with the Safety Act's make-inoperative prohibition, 49 U.S.C. § 30122(b). Request 21 asks how the car complies without an exemption under 49 CFR Part 555.
Update: 2026-10-08
NHTSA has moved Tesla's deadline. A memo to the AQ26002 file dated 29 September 2026, added to the public file on 7 October as IRSPO-AQ26002-19155, shows that Tesla asked on 18 September for eight more weeks, to 20 November. It cited "the voluminous nature of the request" and the need to search its records and review material for privilege. On 22 September NHTSA granted 30 days instead. The 30 September deadline given above no longer applies: Tesla's sworn answers to the 21 requests are now due on 30 October 2026. The memo does not say why the agency granted less time than Tesla asked for.
