What is the minimum width specified for MUTCD barricade type I?

The minimum width specified for a Type I barricade according to the Manual on Uniform Traffic Control Devices (MUTCD) is indeed 24 inches. This specification is important because it ensures visibility and effectiveness in guiding or warning drivers in various scenarios, particularly in construction or road closure situations. The width helps to make the barricade noticeable from a distance, enhancing safety for both motorists and workers. A wider barricade can prevent accidental encounters, as it occupies more space and is more likely to draw attention to the hazard or obstruction. Compliance with this standard is crucial for achieving the intended safety outcomes of the barricade in traffic management.
