The use of high-visibility safety apparel is critical when working close to moving vehicles in a work zone due to the increased risk of accidents and the need for maximum visibility. Workers in these environments are often in proximity to fast-moving traffic where they can be difficult to see, especially under conditions of low light, inclement weather, or during dusk and dawn. High-visibility apparel, such as vests or jackets that are brightly colored and/or have reflective strips, significantly enhances a worker's visibility to drivers, thereby reducing the likelihood of accidents.

In contrast, the other scenarios involve environments where the risk of collision with moving vehicles is minimal or nonexistent. General office work, indoor maintenance activities, and inspections in quiet areas do not present the same visibility hazards as work zones near traffic, making high-visibility apparel unnecessary in those contexts. The primary focus in creating a safe work environment in high-risk areas is to be seen by vehicle operators, thereby prioritizing safety for all personnel on site.
