The SCDOT noted in its video that each road sign is designed as a “traffic control device” that must adhere to five criteria outlined in the Manual on Uniform Traffic Control Devices or MUTCD.

The agency also maintains an intricate online filing system that tracks every road sign used across the state’s transportation network.

The SCDOT noted that aluminum is one of the most common base materials used to create road signs, while the sign’s reflective material is designed to last over a decade.
