Two-Way Traffic Warning Sign - Meaning and Usage #1784633 (License: Personal Use)

This is a U.S. MUTCD-standard warning sign (W1-5) indicating that the road ahead carries traffic in both directions, often used when a one-way street transitions to two-way flow. The high-contrast yellow diamond shape and bold black arrows ensure visibility and immediate recognition by motorists at speed. It is typically mounted before intersections, mid-block transitions, or after temporary closures where traffic patterns change.

Used on roads and highways to warn drivers of an upcoming change from one-way to two-way traffic, especially near construction zones, detours, or permanent route modifications. Matches user intent for understanding traffic signage, driver education, or municipal transportation planning.
