Mandatory Direction Traffic Sign - Down-Left Arrow #1872668 (License: Personal Use)

The sign features a white arrow on a blue circular background with a white border, conforming to Vienna Convention standards for mandatory direction signs. It is commonly placed before intersections, roundabouts, or lane splits where specific routing is enforced.

Used on roads and highways to direct traffic flow, especially where lane discipline or route compliance is critical; matches user intent for understanding traffic signage, driver education, or navigation system design.
