Mandatory Left Turn Traffic Sign - Official Road Signage Guide #297991 (License: Personal Use)

This is a regulatory traffic sign used internationally to indicate that vehicles must proceed in the direction shown-in this case, a left turn. The sign features a solid blue background with a thick white arrow pointing left, enclosed in a white border, conforming to Vienna Convention standards for mandatory direction signs. It is typically mounted at intersections or roadways where traffic flow requires strict directional control.

Used on roads and highways to enforce mandatory movement directions; commonly seen before intersections, roundabouts, or lane splits where left turns are required for safety or traffic management. Matches user intent for understanding road signage, driver education, or legal compliance research.
