When is it critical to utilize reflective materials in traffic control?

Utilizing reflective materials in traffic control is especially critical during low visibility conditions, such as at night or in inclement weather. Reflective materials enhance the visibility of traffic control devices, signs, and markings in these challenging conditions, ensuring that drivers can see and recognize them from a distance. This is essential for maintaining safety on roadways, as poor visibility can lead to increased risk of accidents and confusion among drivers. In low light or adverse weather situations, such as rain or fog, reflective materials ensure that essential information is conveyed effectively, helping to guide and protect drivers and road workers alike.
