What is the main purpose of high visibility gear in traffic incident management?

High visibility gear is designed primarily to ensure that personnel are easily seen by motorists. This is crucial during traffic incidents where the visibility conditions can be compromised due to factors like lighting, weather, or the chaos of the scene. The bright colors and reflective materials used in such gear help enhance the safety of first responders by making them more conspicuous, reducing the risk of accidents and allowing motorists to notice them from a distance. This visibility is especially important in ensuring the safety of emergency responders who are working in close proximity to active traffic, as it helps signal to drivers to slow down or navigate carefully around the scene.

In contrast, considerations like weight reduction, temperature maintenance, and fashion do not address the urgent safety needs that high visibility gear is intended to fulfill in traffic incident management.
