What is a critical aspect of personal safety at a roadway incident scene?

Wearing high-visibility clothing is a critical aspect of personal safety at a roadway incident scene because it significantly enhances the visibility of individuals working in potentially hazardous conditions. Roadway incidents often involve heavy traffic, and emergency responders or safety personnel need to be easily seen by drivers to minimize the risk of accidents. High-visibility clothing, typically made from bright colors and reflective materials, ensures that workers stand out against the background, even in low-light conditions or poor weather.

By increasing the likelihood that drivers will notice the presence of workers, high-visibility clothing helps prevent secondary collisions and injuries, which are common risks at incident scenes. This safety measure is essential not only for the individuals directly involved in managing the incident but also for the safety of all motorists approaching the scene.
