The All Traffic Must Turn Left sign (R3-7-1L) is a regulatory traffic sign used to require all approaching vehicles to make a left turn at an intersection or designated roadway location. Commonly installed at road closures, detours, channelized intersections, and construction zones, this 30" x 30" sign provides clear instruction to safely direct traffic and prevent prohibited movements. Manufactured to MUTCD standards, it offers high visibility, durability, and long-term performance for municipal, contractor, and commercial traffic control applications.
