SmartSign "Slow Down - Only You Can Prevent Speed Bumps" Sign | 12" x 18" 3M Fluorescent Diamond Grade Reflective Aluminum

Reflective Signs Are Hard to Ignore Easy to spot by day, and reflective at night, this Slow Down - Only You Can Prevent Speed Bumps sign reminds drivers to reduce their speed and obey traffic rules on your property. 3M Diamond Grade [DG] Reflective 3M Diamond Grade Fluorescent Yellow signs offer the brightest reflectance. These offer three times the reflectivity of High Intensity and ten times the reflectivity of Engineer Grade reflective signs. Fluorescent signs are exceptionally conspicuous and make your message hard to miss. These are ideal for schools and crosswalks. Signs combine the high daytime and twilight conspicuity of fluorescent colors with the high nighttime reflectivity and wide angle performance of 3M microprismatic lens technology. This makes the Slow Down Sign uniquely conspicuous at the most dangerous times of the day (at dawn and at early evening times). USAs Oldest Sign Manufacturer You can now buy the exact same signs that you see on public roads. Our South Dakota factory is the oldest manufacturer of outdoor signs in the USA. Family owned since 1918, we take enormous pride in our signs and have been an integral part of the progression of our national traffic sign designs and specifications over the years. Fluorescent yellow is approved by the U.S. Federal Highway Administration (FHWA) for use on all yellow warning signs such as no passing zone, stop ahead, yield ahead, and roadway alignment signs such as curve arrows and chevron signs. Industry Leading Durability 3M Diamond Grade signs have 12 years of outdoor warranty, but most signs last much longer. Our 63 mil thick aluminum signs are laminated for enhanced performance. Unlike many other signs, our signs use industry-leading 3M inks and not off-brand or other low-durability inkjet pigments that fade in a year or two.
