U.S. Route signs are standardized markers used to identify highways and roads in the United States. These signs typically feature a white shield shape with a black outline, displaying the route number in bold digits. They help drivers navigate the extensive network of U.S. highways that connect cities and regions across the country. Each U.S. Route sign indicates a specific highway, allowing travelers to easily follow their intended path. The signs are part of the Manual on Uniform Traffic Control Devices (MUTCD), which ensures consistency in road signage. This uniformity aids in safety and efficient travel for all road users.
