Reflective Signs Save Lives
Easy to spot by day, and reflective at night, this No Thru Traffic Sign indicates drivers not to use the street as a through way.

3M High Intensity [“HI”] Reflective
3M High Intensity reflective signs offer exceptional reflectance - especially when approached at an angle. 3M High Intensity signs have 10-year outdoor warranty.

USA's Oldest Sign Manufacturer
Family owned since 1918, we take immense pride in our signage. Being one of the oldest certainly means we know this business in and out. Our South Dakota factory is the oldest manufacturer of metal signs in the USA. We have been an integral part of safety and convenience our Road Traffic Signs have provided over the years.

Industry Leading Durability
3M High Intensity signs have a 10-year outdoor warranty, but most signs last much longer. Our 80 mil thick Aluminum Private Driveway Sign is laminated for enhanced performance. You can clean off graffiti and your graphics are protected. Unlike many other signs, our No Thru Traffic signs use industry-leading 3M inks and not off-brand or other low-durability inkjet pigments that fade in a year or two.
