This is an online guide to making and installing traffic signs within the standards of the USDOT.
In any state in the United States, you can’t install traffic signs without some sort of governmental permission, typically a local, state, or federal DOT. It’s the same with most other countries run by a government. There are standards one must follow to be able to install highway and street signs, from the design, materials, and location of these signs.
Custom signs displayed along streets, roads or highways must adhere to the standards set by the department of transportation.
