What does MUTCD stand for?

MUTCD stands for the Manual on Uniform Traffic Control Devices. This manual provides standards for all traffic control devices, including signage, signals, and pavement markings, to ensure uniformity and safety across roadways in the United States. The purpose of this uniformity is to promote better understanding and compliance by road users, thereby enhancing overall roadway safety and efficiency.

The other options do not accurately reflect the established title or purpose of the manual. For instance, while certain terms like "method" or "model" might relate to traffic control in a general sense, they do not capture the authoritative and comprehensive nature of the manual itself. Additionally, "minimal" in the context of traffic design implies a less rigorous framework, which contrasts with the comprehensive guidelines outlined in the MUTCD.
