What is one significant reason for linemen to wear high-visibility clothing?

Wearing high-visibility clothing is crucial for linemen primarily because it ensures they are easily spotted by both drivers and coworkers. This visibility is essential for safety, especially when working in areas with vehicular traffic or in low-light conditions. High-visibility clothing, often characterized by bright colors and reflective materials, helps prevent accidents by making linemen more recognizable from a distance. When linemen are visible, it significantly reduces the risk of accidents and enhances overall workplace safety by allowing others to see them clearly and anticipate their movements.

The other choices do not address the primary safety concern that high-visibility clothing is designed to mitigate. Staying cool in hot weather, complying with color standards, or expressing personal style are not the main purposes of these safety garments. The primary focus in the context of linemen is safety and visibility.
