The R3-18 sign prohibits both U-turns and left turns at the intersection where it is installed. Combines the No U-Turn (R3-4) and No Left Turn (R3-2) symbols on a single sign with a white retroreflective background. Used at intersections where both maneuvers are prohibited, eliminating the need for two separate signs.

Choose the sign size based on roadway type and required visibility. The 24" x 24" is commonly used for single-lane conventional roads and lower-speed applications. The 36" x 36" is used for multi-lane roads, expressways, and locations needing increased visibility. The 48" x 48" is an oversized option for higher-emphasis installations. Manufactured on .080" rustproof aluminum with rounded corners and pre-punched mounting holes. Hardware sold separately. 48" signs ship truck freight.
