Why this one is quoted
Official traffic signs are quoted rather than listed. Size, sheeting grade and quantity move the cost far more than they do on a printed panel, and we are not going to publish a number we might have to walk back. Tell us the code, the size, the grade and how many — you get a specified quote, not a guess.

Scope of this product
Manufactured to MUTCD and Standard Highway Signs specifications on ASTM D4956 retroreflective sheeting. Sold for authorized use. Whether a sign is warranted at a given location, which sheeting grade and size your jurisdiction requires, and how it is installed and maintained are the responsibility of the agency, owner or contractor placing it — we help you get it right, and we will not guess it for you. We make no certification claim, and we publish no durability term until your fulfilment path is set.
