Why are cones, drums, and barricades placed in construction zones?

Cones, drums, and barricades are essential tools used in construction zones to clearly guide drivers through areas that are undergoing work. These physical barriers help to establish safe lanes for vehicles and indicate areas that are off-limits or hazardous. By visually directing traffic away from construction activities, they enhance safety for both drivers and workers on-site.

Using these items effectively communicates to drivers where to navigate, ensuring that they follow designated paths and reduce the risk of accidents. This organization is crucial in maintaining a smooth flow of traffic while protecting the workers who are conducting the construction tasks. Overall, the deployment of these safety devices is aimed at facilitating a safer navigation experience around construction zones.
