The articulated haulers relatively small size also make them able to drive on public roads between different worksites at a large construction project—something that is impossible for the largest haul trucks, which might even have to be disassembled to be moved between different locations. For transportation between different construction projects, articulated haulers usually have to be hauled on flatbed trailers as oversize cargo due to their width and weight, as well as their limited speed. However, in reality, it is normal for most articulated trucks to be trailered between worksites, as there are few construction sites giving an opportunity to drive on public roads between work zones, depending on the size of the machine (chassis, wheels, etc.) and the local laws this could also be illegal. For any distance greater than a few miles, it would also be considered uneconomical wear-and-tear on the hauler trucks, to be putting hours on them that aren't contributing towards the paying job. It is far more efficient and quicker to use trucks and trailers and let them do what they specialize in, over-road hauling.
