What two main groups should be protected in work zones?

The correct answer highlights the importance of ensuring safety for workers and pedestrians in work zones. Workers are at risk due to machinery, moving vehicles, and various hazards associated with construction sites. Protecting them is critical to avoid accidents and injuries on the job.

Pedestrians also face considerable risks in areas where construction or road work is taking place, as they may inadvertently walk into hazardous areas or come into contact with construction equipment or vehicles. Therefore, implementing safety measures to protect both these groups is essential for maintaining a safe work environment and preventing injuries.

This focus on safeguarding both workers and pedestrians underscores the broader aim of work zone safety, which is to create a secure passage through areas where work is being performed, thereby reducing the likelihood of accidents involving both those who are employed on site and those navigating through or around the work zone.
