The Manual on Uniform Traffic Control Devices (MUTCD) is a document published by the Federal Highway Administration that provides guidelines for traffic signs, signals, and pavement markings. Its primary goal is to ensure consistency and safety in traffic control across the United States, helping drivers and pedestrians understand and follow road rules effectively. The MUTCD outlines standards for various traffic control devices, including their design, placement, and usage. By adhering to these guidelines, state and local agencies can create a safer driving environment, reduce confusion, and improve overall traffic flow on public roads.
