The NHTSA is investigating Tesla's 'Full Self-Driving' system following a fatal collision.

• The U.S. federal automotive safety regulator, NHTSA, is conducting a safety investigation into Tesla's "Full Self-Driving" feature.
• Tesla's FSD systems will be assessed for safety in fog, bright sun, and reduced road visibility conditions by the probe.
• A Tesla probe has been launched after a series of collisions involving FSD within 30 seconds of the crash, including one where a Tesla driver fatally struck a pedestrian.

A Tesla driver who was using FSD struck and killed a pedestrian, and there were other FSD-involved collisions during reduced roadway visibility conditions.

The NHTSA conducted a preliminary evaluation of approximately 2.4 million Tesla EVs on U.S. roads, including Model S and X vehicles produced from 2016 to 2024, Model 3 vehicles produced from 2017 to 2024, Model Y vehicles produced from 2020 to 2024, and Cybertruck vehicles produced this year and last, which offer drivers the option to use Tesla's FSD.

Tesla's "partial driving automation system," now referred to as FSD, is a paid, premium driver assistance option. However, the company previously offered it to all drivers in the U.S. for a free monthlong trial.

The National Highway Traffic Safety Administration (NHTSA) monitors collisions involving automakers' advanced driver assistance systems, including Tesla's Autopilot and FSD, and as of October 1, 2024, had recorded 1,399 incidents where Tesla's driver assistance systems were active within 30 seconds of the collision, resulting in 31 fatalities.

Tesla CEO Elon Musk announced at a recent marketing event that the company plans to launch "unsupervised FSD" in Texas and California next year in its Model 3 and Model Y electric vehicles.
