Road signs practice test

Sign shapes and colors are set by the federal Manual on Uniform Traffic Control Devices (11th Edition, Revision 1 (December 2025)), which every state adopts. Learn them once and they hold in any state. The signs shown are the official MUTCD designs (public-domain artwork).
