Page 28 of the Rice Signs 2017 Traffic Safety Catalog begins the School & Pedestrian Signs section. The page covers three groups: School & Pedestrian Safety Signs (the S1 series fluorescent yellow-green School Crossing pentagons, S3 series school zone signs, S4 School Speed Limit plaques, W11 pedestrian and bicycle crossing diamonds, W15-1 Playground, W16 supplemental plaques, and R20-8 School Crossing Guard); Unsignalized Pedestrian Crosswalk Signs (R1-5 series Yield To Pedestrian signs with left and right arrow variants for marked crosswalks); and Pedestrian In-Street Crossing Signs (R1-6 black-on-yellow and white-on-black variants designed for placement in the road median or at the crosswalk centerline). All signs use the MUTCD fluorescent yellow-green ink for school zones and are fabricated on 0.080 aluminum with Engineer Grade or HIP reflective sheeting.
