Hi vis apparel is mandatory for highway construction safety. Highway construction workers are much too close to oncoming traffic and all sizes of vehicles, some of which don't obey the construction zone speed limits.
In the evening, it's even more dangerous. So for workzone crews, or any construction worker that needs to be easily seen, wearing a retroreflective safety vest can be a lifesaver.
Hi-visibility safety awareness campaigns also go a long way, not only for protecting roadside crews but also for pedestrians and motorists from potentially harming these construction workers.
Construction workers on the highway need increased visibility especially after dark. Performing their duties without high visibility gear would endure an accident. Add any kind of detrimental weather and it makes it nearly impossible to see them.
