Labelmaster Stop Signs are made from durable, heavy-duty, rust-proof 0.08" thick aluminum. The high-intensity, prismatic sheeting makes these stop signs over 3 times brighter than standard engineer-grade sheeting. These stop signs retain 80% of the original brightness after 10 years of use. 24"×24" size and greater stop signs are
Manual on Uniform Traffic Control Devices (MUTCD) compliant. *NOTE: The 18"×18" stop signs are not MUTCD compliant for accessible public roads, but are great for crossing guards.
