What is one best practice for a flagger concerning their equipment?

Using bright and reflective clothing is critical for a flagger's safety and visibility. This best practice ensures that the flagger can be easily seen by both drivers and workers in the work zone, especially in low-light conditions or in the presence of inclement weather. Bright colors, such as fluorescent orange or yellow, increase recognition and awareness, allowing motorists to react appropriately to the flagger's signals. The reflective materials further enhance visibility at night or during poor visibility, significantly reducing the risk of accidents.

The other options do not prioritize safety or visibility in the same way. Casual clothing may compromise the flagger's visibility and professional appearance, while carrying minimal supplies can hinder their ability to perform efficiently. Using dull-colored flags would not attract attention and could lead to confusion among drivers, undermining the flagger’s role in directing traffic safely.
