## Narrative
I am submitting this complaint to report a safety concern involving Tesla’s Full Self-Driving (FSD) system.  On [XXX], while my vehicle was operating under FSD in Las vegas NV, the vehicle was positioned in a clearly marked left-turn-only lane. The roadway had visible pavement arrows indicating a required left turn.  Despite these clear lane-direction markings, the FSD system proceeded straight instead of turning left.  The maneuver occurred abruptly. I did not receive a clear or timely takeover warning prior to the deviation. The transition from a left-turn lane into a straight path happened quickly, leaving extremely limited reaction time (estimated less than one second).  As a result of the system’s unexpected behavior, a collision occurred with another vehicle traveling straight.  At the time of the incident:  Weather conditions were clear.  Road markings were visible.  There were no obstructions blocking lane markings.  I was attentive and looking at the road.  The police report assigned fault to me as the driver; however, the vehicle was actively operating under Tesla’s FSD system when it disregarded the clearly marked left-turn-only lane.  I am concerned that this behavior represents a potential safety defect involving:  Lane interpretation errors  Failure to follow traffic control markings  Insufficient takeover warning timing  If this issue is systemic, it may pose a broader safety risk to other road users.  I respectfully request that NHTSA review this matter
