What is a key benefit of using reflective vests on construction sites?

Using reflective vests on construction sites significantly enhances safety by improving visibility. This is particularly important in environments where construction work is taking place, as workers often operate near heavy machinery, vehicles, or at times when lighting conditions are poor. The bright colors and reflective materials of these vests help ensure that workers are easily seen by their colleagues and operators of vehicles, minimizing the risk of accidents and injuries.

The other options, while they may have relevance in certain contexts, do not directly address the primary purpose of reflective vests. Durability can be a factor in choosing materials for vests, but it does not relate to safety as directly as visibility does. Similarly, temperature control and comfort can be considerations in the design of work gear, but they are secondary to the critical need for workers to be seen in hazardous working conditions. Thus, focusing on visibility aligns directly with the safety protocols that are essential on construction sites.
