US automobile safety regulators have commenced an probe into Tesla vehicles featuring the autonomous driving system due to safety regulation breaches following numerous collisions.
The NHTSA stated that the electric carmaker's self-driving assistance system, which requires drivers to remain attentive and take control when necessary, had “induced car behavior that violated traffic safety laws”.
This initial assessment by the NHTSA represents the first step before potentially seeking a recall of the vehicles if the agency determines they present a danger to road safety.
The regulatory body stated it had received accounts of 2.88 million Tesla cars running red traffic lights and traveling against the wrong way during lane changes while operating the system.
NHTSA stated it has six reports in which a Tesla vehicle, operating with FSD activated, “came to an junction with a red light, continued to travel into the intersection despite the red signal and was subsequently involved in a collision with other cars in the intersection”.
The agency reported that four crashes had caused injuries to occupants.
The NHTSA announced it has identified 18 complaints and one media report alleging that Tesla vehicles, driving through an intersection with FSD active, did not stay stopped for the duration of a red traffic signal, failed to stop fully, or failed to accurately detect and show the correct light status in the car's display”.
Some complainants also stated that FSD “failed to give alerts of the system's intended actions as the vehicle was approaching a red traffic signal”.
Tesla's FSD, which is more sophisticated than its basic autopilot feature, has been under investigation by NHTSA for a year.
In late 2024, the agency started an inquiry into 2.4 million Tesla cars equipped with FSD after four documented crashes in situations of poor visibility, such as bright sunlight, fog or dust clouds. One such accident, in 2023, was fatal.
Tesla's website states that FSD is “intended for operation by a fully attentive motorist, who has their hands on the wheel and is ready to take over at any time. While these capabilities are engineered to improve over time, the presently active functions do not render the car self-driving.”
Self-driving car systems continue to face growing examination from regulatory bodies as the technology advances and real-world testing reveals potential challenges with existing deployments.
