Mandatory Left Turn Traffic Sign - Official Road Signage Guide #257112 (License: Personal Use)

This standardized traffic sign features a white left-turn arrow on a blue circular background with a white border, indicating that drivers are required to turn left at the next intersection or junction. It is commonly used in urban and highway settings to manage traffic flow and prevent illegal maneuvers. The sign complies with international road signage conventions (e.g., Vienna Convention) and national standards like MUTCD or UK TSRGD.

Used on roads, highways, and intersections to enforce directional movement; typically placed before an intersection where left turns are compulsory. Matches user intent for understanding traffic rules, preparing for driving tests, or designing road safety materials.
