Which of the following is a reason for using temporary barriers in work zones?

Using temporary barriers in work zones primarily serves to increase safety by directing vehicles safely around the work area. The presence of these barriers helps to protect both road users and construction workers by clearly defining the boundaries of the work zone. This minimizes the risk of accidents, as it aids in guiding traffic away from hazardous areas and reduces confusion for drivers navigating through or around the construction area.

While other factors such as project efficiency and site aesthetics can play roles in work zone management, the primary focus of temporary barriers is safety. They are designed to keep vehicles at a safe distance from construction activities, thereby enhancing the overall protection for everyone involved in or adjacent to the work zone.
