Which item is often more difficult to transport compared to cones?

Drums and barrels are often more difficult to transport compared to cones due to their size, weight, and shape. While traffic cones are typically lightweight, stackable, and designed for easy portability, drums and barrels have larger dimensions and can be cumbersome to handle. They generally require more space for loading and may not fit as easily into vehicles. Additionally, the structure of drums and barrels often makes them less stable when stacked or moved, increasing the challenges in transportation compared to the more straightforward design of cones. This distinction emphasizes the logistical challenges involved in transporting various traffic control devices within work zones.
