Road Narrows Warning Sign - Meaning and Safety Guidance #1645703 (License: Personal Use)

The image shows a regulatory warning sign used internationally: a red-bordered equilateral triangle with a white background and a black symbol of two parallel lines converging inward, indicating a reduction in lane width. This sign is typically placed before sections where the road narrows due to construction, obstacles, or permanent design changes. Drivers must prepare to merge or adjust speed to avoid collisions.

Used on highways, urban roads, and construction zones to warn motorists of upcoming lane reductions; matches user intent for understanding traffic signage, driver education, or road safety compliance.
