No U-Turn Sign - Official Traffic Regulation Symbol #1840367 (License: Personal Use)

The image displays two variants of the internationally recognized "No U-Turn" traffic sign: a full-color version with a red circle, diagonal slash, black U-turn arrow, and downward arrow; and a grayscale line-art version suitable for printing, schematics, or accessibility contexts. Both follow Vienna Convention on Road Signs and Signals standards for clarity and universal recognition.

Used on transportation websites, driver’s manuals, municipal signage guides, and traffic engineering resources to illustrate prohibited maneuvers; matches user intent for understanding road rules, designing signage, or preparing driver education materials.
