This is a regulatory traffic sign used internationally to indicate that vehicles must turn left at the upcoming junction. The sign features a solid blue circular background with a bold white arrow pointing left, conforming to Vienna Convention standards for mandatory direction signs. It is typically mounted above or beside the road ahead of intersections where left turns are required for traffic flow or safety.

Used on roads, highways, and urban streets to enforce mandatory turning directions; commonly seen before intersections, roundabouts, or lane-dividing points where left movement is compulsory. Matches user intent for understanding traffic rules, driver education, or signage compliance.
