Why is it crucial to use high-visibility vests at roadway incidents?

Using high-visibility vests at roadway incidents is crucial primarily because they ensure that personnel are easily visible to passing traffic. Roadway incidents often involve moving vehicles, and visibility is paramount to ensure the safety of emergency responders. High-visibility vests are designed with bright colors and reflective strips, allowing them to stand out against the backdrop of the roadway and in various lighting conditions, including nighttime and inclement weather. This visibility is essential not only to protect the personnel but also to remind drivers to be cautious and attentive when navigating through the incident scene. Enhanced visibility thereby reduces the risk of accidents involving emergency responders and increases the overall safety of everyone at the scene.
