Mandatory Bicycle Lane Sign - Official Road Signage Guide #1982518 (License: Personal Use)

This is a regulatory traffic sign used internationally (especially in Europe and under the Vienna Convention) to indicate that bicycles must use the designated lane or path. The blue circular background with a white bicycle silhouette signifies a mandatory instruction, not merely a suggestion. It is commonly installed on roads, bridges, and urban corridors to separate and prioritize cycling traffic for safety and efficiency.

Used on transportation websites, road safety guides, municipal infrastructure pages, driver’s education materials, and cycling advocacy resources. Matches user intent for understanding traffic signage, planning bike-friendly routes, or complying with local traffic laws.
