The National Highway Traffic Safety Administration (NHTSA) has opened an Audit Query, numbered AQ26002, into the technical data and process Tesla used to self-certify that its new Cybercab complies with all applicable Federal Motor Vehicle Safety Standards (FMVSS), according to an NHTSA press release and reporting by the New York Times and Electrek. The investigation, opened September 3, 2026, covers an estimated 1,000 Cybercab vehicles and was prompted by public information, according to the filing.
A Vehicle With No Manual Controls
Cybercab has no steering wheel or pedals, and Tesla began putting paying passengers in the vehicles in Austin, Texas the same day the audit was opened. NHTSA said it will examine “the extent to which Tesla’s certification depended on determinations that certain FMVSS are inapplicable to the Cybercab,” according to Electrek, focusing on whether standards written for vehicles with traditional human controls can be validly waived for a fully autonomous design.
How Self-Certification Works
Under the US system, automakers certify their own compliance with federal safety standards rather than obtaining pre-approval from regulators, with NHTSA auditing that certification after the fact. The audit will assess the technical data and processes underlying Tesla’s compliance determination and how occupant protection is addressed in a vehicle operating without a human driver behind physical controls, according to NHTSA.
Stakes for Tesla’s Robotaxi Rollout
Tesla has said it plans to gradually expand Cybercab deployment to more vehicles and locations. The outcome of the audit could influence the pace of that expansion and is being closely watched as a test case for how federal vehicle safety standards, largely written around human-operated cars, apply to commercially deployed vehicles with no manual controls at all.
