Two-Way Traffic Warning Sign - Meaning and Usage #2042212 (License: Personal Use)

This is a U.S. MUTCD-compliant warning sign (W1-5) used to indicate that a single lane carries traffic in both directions, often found on narrow bridges, mountain roads, or temporary detours. The bright yellow diamond shape signals caution, while the black upward and downward arrows clearly convey opposing traffic flow. Drivers must yield appropriately and be prepared for oncoming vehicles.

Used on roadways where lanes are shared by opposing traffic, especially in construction zones, rural bridges, or historic streets. It supports user intent to understand traffic signage for safe driving, driver’s education, or transportation planning.
