Three Lane Straight Ahead Road Sign - Traffic Signage Guide #1840697 (License: Personal Use)

The image displays a standard European-style mandatory direction sign (Type C1), featuring a deep blue rectangular background with a white border and three evenly spaced white upward-pointing arrows. It is used on multi-lane roads to inform drivers that all three lanes are designated exclusively for straight-ahead movement, prohibiting turns unless otherwise indicated. The high-contrast design ensures visibility and compliance under various lighting conditions.

Commonly placed above multi-lane highways or urban arterials before intersections where lane-specific movements are enforced; used by transportation departments, driving manuals, and road safety education to clarify lane usage and prevent illegal turns.
