This is the internationally recognized “No Entry” traffic sign ( Vienna Convention on Road Signs and Signals, sign C1), featuring a solid red circular background with a thick white horizontal bar centered across the disc. It legally prohibits all vehicular traffic from entering a road or lane, commonly placed at one-way street entrances, restricted zones, or dead-end roads. The high-contrast design ensures visibility and immediate recognition under varied lighting conditions.
