Description

The R1-1 is the standard octagonal stop sign required at intersections where a full stop is mandated. White "STOP" legend on a red retroreflective background.

Three sizes cover every MUTCD roadway classification. The 30" x 30" is for single-lane and low-volume roads. The 36" x 36" is for multi-lane roads and expressways. The 48" x 48" provides enhanced conspicuity where oversized signage is required. The 30" and 36" sizes mount to a single post. The 48" size requires a two-post mount.

Reflective sheeting options vary by size. Sign post, mounting hardware, and brackets are sold separately.

NOTE: 48" signs ship truck freight.
