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. These signs are uniquely conspicuous at the most dangerous times of the day — dawn and early evenings
Orange 2-way traffic signs are usually posted on road work zones to regulate the traffic flow and ensure worker safety. We offer these signs in three grades of reflectivity — engineer, high-intensity, and diamond. The 3M Diamond Grade Fluorescent Orange two-way traffic sign is the brightest of all, with high daytime conspicuity and the best nighttime reflectivity.
Made using heavy gauge, 63 and 80 mil thick rustproof aluminum, our two-way traffic signs come with an outdoor life of at least 10 years. Branded 3M inks and materials used on the signs prevent fading and provide enhanced visibility. You may further extend the life of your sign by opting for the 3M SmartShield POF Laminate during checkout.
Most of our diamond-shaped two-way road signs are available in 24”, 30”, and 36” sizes, with the exception of the Wait diamond-shaped sign offered in 12” and 24” sizes. The rectangular two-way traffic signs come in varied sizes starting from 12”x18” to as large as 24”x48” and 30”x36”. Individual sign-specific sizes can be found on product pages.
