The National Highway Traffic Safety Administration is weighing allegations that Tesla's driverless taxis fail to keep speeds down in active school zones. The question on the table is whether automated systems in the Cybercab and Model Y are respecting posted limits when those zones are in effect.
The evaluation was triggered by a newly filed petition that includes videos of multiple incidents, according to documents posted Monday on NHTSA's website. For now, the preliminary review spans an estimated 1,000 vehicles tied to the 2026 model year. A determination on the petitioner's request to launch a full investigation has not been made by the agency. Bloomberg reported Tesla did not immediately respond to its request for comment.

This adds another wrinkle for Tesla's robotaxi push, which rolled out last year but remains available in a limited number of cities and, in some cases, relies on human safety monitors. Elon Musk has cast the service as a pillar of shifting the company toward autonomous driving and humanoid robots. Separately, NHTSA is examining the process and technical data Tesla used to self-certify the Cybercab, a two-seat vehicle with no steering wheel or pedals.
Regulators are also looking at Alphabet's Waymo over different school-related incidents. Late last year, NHTSA launched a probe, and several months afterward the National Transportation Safety Board began a similar investigation, stemming from incidents where Waymo vehicles failed to sufficiently reduce speed or come to a stop around school buses.
More regulatory checkpoints can slow deployments, add costs, and reset expectations for companies betting on autonomy to drive growth. The key signals to watch: whether this preliminary Tesla review becomes a formal investigation and how operators address school-related performance issues. Those outcomes shape public trust and, eventually, real-world adoption that shows up in products you can actually hail.
