When wearing high-visibility vests at a roadway incident, responders should not engage in fire fighting or hazardous materials activities primarily for safety reasons. High-visibility vests are intended to enhance the personnel's visibility to motorists and other responders, thereby reducing the risk of accidents and injuries.

During roadway incidents, the primary focus while wearing these vests is to ensure the safety of the responders in an environment where vehicles are present and potentially moving at speed. Engaging in fire fighting or hazardous materials operations could distract from the critical task of maintaining situational awareness, which is necessary to avoid accidents in a dynamic and potentially hazardous setting.

High-visibility vests are specifically designed for use in situations where visibility is paramount, and while assisting with tasks like traffic control is appropriate, those wearing these vests should refrain from engaging in other activities that compromise their safety or the effectiveness of their visibility. By limiting their actions to roles that prioritize safety, responders can better protect themselves and others on the scene.
