In work zones, what is the purpose of barriers such as drums, cones, and tubes?

The purpose of barriers such as drums, cones, and tubes in work zones is primarily to keep traffic out of hazardous areas. These barriers serve as physical obstacles that guide and restrict the flow of vehicles, ensuring that drivers stay away from construction activities, equipment, and workers. This is crucial for maintaining safety, as construction sites often present dangers such as open trenches, heavy machinery, and other potential threats to both drivers and workers.

While these barriers may also offer some degree of directional guidance, their main function is to protect everyone involved in or near the work zone from accidents or injuries that could occur if vehicles were to enter into unsafe areas. Therefore, the use of these barriers is an essential element of traffic management in work zones, helping to reinforce the need for caution and awareness while drivers navigate through potentially dangerous environments.
