According to MUTCD 6F.64, what color must traffic cones predominantly be?

Traffic cones are predominantly orange in accordance with the Manual on Uniform Traffic Control Devices (MUTCD) 6F.64. The choice of orange is intentional, as it provides high visibility during the day and night, making it easier for drivers and pedestrians to see the cones from a distance. The orange color signals caution and indicates the presence of work zones or hazards on roads, ensuring that motorists are alerted to potential dangers. This visibility is crucial for maintaining safety near traffic incidents and construction sites, as it helps to guide vehicles and pedestrians safely around the area. The use of a standardized color like orange also ensures consistency across different jurisdictions, making it easier for road users to recognize and respond appropriately to traffic management devices.
