NHTSA Investigates Tesla FSD and Robotaxi Safety
The U.S. National Highway Traffic Safety Administration is investigating Tesla's Full Self-Driving system and planned Robotaxi service, focusing on performance in adverse weather conditions where the system has reportedly caused four prior accidents. The regulator is examining safety protocols before Tesla deploys a fully autonomous version without driver monitoring.
What happened
The U.S. National Highway Traffic Safety Administration (NHTSA) has issued a series of inquiries to Tesla regarding its Full Self-Driving (FSD) software and planned Robotaxi service. NHTSA's defects investigation office (ODI) is conducting a continued investigation into FSD.
The agency is focusing on FSD system performance in adverse weather and lighting conditions including fog, rain, and bright light. Prior to this investigation, FSD had been involved in four accidents in low-visibility environments.
NHTSA is also inquiring about Robotaxi safety testing plans on public roads. The regulator seeks confirmation of whether the planned fully autonomous Robotaxi version will be consistent with the current road version of FSD, which currently requires driver monitoring and hands on the steering wheel.
Reported impact
Tesla is required to respond to NHTSA inquiries by June 19, 2025. The investigation addresses concerns about the safety of autonomous driving technology before deployment of a fully unsupervised Robotaxi service.
Index analysis
The investigation focuses on FSD's reliability in challenging environmental conditions where the system has previously failed. Four documented accidents in low-visibility conditions suggest potential gaps in the system's ability to perceive and respond safely.
The regulatory scrutiny reflects concerns about deploying a fully autonomous vehicle service without adequate safety validation, particularly regarding whether a new autonomous version would be compatible with or equivalent to the current supervised driving system.
Governance controls
NHTSA's investigation represents formal regulatory oversight of autonomous vehicle development before deployment. The agency is requiring Tesla to provide documentation on vehicle quantities, operating areas, and safety validation methods for the Robotaxi program.
