The Do Not Pass sign (R4-1) is a regulatory traffic sign used to prohibit passing maneuvers in designated roadway segments where visibility or road conditions make passing unsafe. Commonly installed on two-lane roads, highways, and no-passing zones, this 24" x 30" sign provides clear instruction to drivers to improve roadway safety and reduce collision risk. Manufactured to MUTCD standards, it offers high visibility, durability, and long-term performance for municipal, contractor, and commercial traffic control applications.
