US auto safety regulators have opened an investigation into the Amazon-owned self-driving technology company Zoox’s self-certification claims, which say its robotaxis meet and exceed the National Highway Traffic and Safety Administration (NHTSA)’s Federal Motor Vehicle Safety Standards (FMVSS).

The NHTSA sets requirements for purpose-built cars without traditional vehicle controls like steering wheels and pedals (these are the robotaxis developed by Zoox). In September 2022, the NHTSA directed Zoox to submit answers for the basis for certifying its vehicle; that review is said to be ongoing. The NHTSA stated that they will conduct an investigation into Zoox's self-certification of its robotaxis to determine whether Zoox created its own testing procedures or if they decided certain regulations did not apply to their vehicle because of its unique design.

Zoox, however, is positive that the self-certification meets and exceeds the stipulated requirements. It will continue to work with the NHTSA on the questions the authority might have.

Analyst QuickTake: Today’s news on the opening of the probe into Zoox’s self-certification comes on the heels of the company obtaining permission from the California Department of Motor Vehicles (DMV) to test its custom-built robotaxis on public roads in California.
