Which of the following best describes the role of high-visibility vests for ramp agents?

High-visibility vests are an essential safety measure designed primarily to enhance visibility and safety for ramp agents working in busy airport environments. These vests are typically made from bright-colored, reflective materials that ensure ramp agents are easily seen by vehicle operators and other personnel, which is crucial in areas with a lot of moving machinery and aircraft. The bright colors help to prevent accidents by making the agents more noticeable, especially in low-light conditions or during inclement weather.

The emphasis on safety through visibility is vital, as ramp agents often work in close proximity to large vehicles and aircraft that can pose significant hazards. Having a high-visibility vest helps to create a safer working environment and minimizes the risk of accidents. While aspects like authority or compliance with regulations play a role in the overall function of a ramp agent, the primary purpose of these vests is distinctly focused on enhancing visibility to protect personnel on the ramp.
