Left Turn Only Traffic Sign - Meaning, Regulations & Safety Guidance #3340420 (License: Personal Use)

The image shows a rectangular traffic sign with a thick black border and rounded corners, featuring a bold black arrow that curves sharply left from the bottom-right toward the left edge. This is a regulatory sign used internationally to indicate that vehicles in the associated lane must turn left, often placed above lanes or at intersections where straight-through movement is prohibited. Its high-contrast design ensures visibility under varied lighting conditions.

Used on roads, highways, and urban intersections to guide driver behavior and enforce lane discipline; matches user intent for understanding traffic signage, preparing for driving tests, or designing transportation infrastructure.
