American vehicle safety authorities have started an probe into Tesla cars equipped with the autonomous driving system due to safety regulation breaches following multiple collisions.
The NHTSA declared that the automaker's self-driving assistance system, which demands drivers to stay alert and take control when necessary, had “induced vehicle behaviour that breached road safety regulations”.
This initial assessment by the NHTSA represents the first step before possibly 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 nearly 3 million Tesla cars driving through red traffic lights and traveling against the incorrect way during lane changes while using the technology.
NHTSA confirmed it has six reports in which a Tesla car, using FSD activated, “approached an intersection with a red traffic signal, continued to drive into the crossroads against the red light and was subsequently part of a collision with other motor vehicles in the intersection”.
The authority reported that four crashes had caused one or more injuries.
The NHTSA announced it has found 18 complaints and one news account claiming that Tesla cars, operating at an intersection with FSD engaged, did not stay stationary for the duration of a red light, did not come to complete stop, or did not properly recognize and display the correct traffic signal state in the vehicle interface”.
Several reporters also claimed that FSD “failed to give alerts of the system's planned behaviour as the vehicle was coming to a red traffic signal”.
Tesla's FSD, which is more advanced than its Autopilot system, has been being examined by NHTSA for a year.
In late 2024, the agency started an investigation into 2.4 million Tesla cars using FSD after four documented crashes in conditions of reduced visibility, such as bright sunlight, mist or dust clouds. One of these collisions, in last year, was fatal.
Tesla's website states that FSD is “designed for operation by a completely alert motorist, who has their hands on the wheel and is prepared to take over at any time. While these features are designed to improve over time, the currently enabled functions do not render the vehicle self-driving.”
Automated car systems continue to face growing examination from safety agencies as the technology advances and real-world testing reveals possible issues with existing deployments.
