Construction zone vehicles are usually large and slow moving. Heavy machinery like bulldozers, excavators, dump trucks, and other equipment used in road work can’t travel quickly due to their size, weight, and the loads they carry. This slower pace helps keep workers safe and gives drivers more time to react to equipment entering or leaving the roadway or to changes in traffic patterns. Bright colors are common for visibility, but the defining trait you’ll notice most across many work zones is their large size and slower speed. When you see construction activity, slow down, increase following distance, and be prepared for sudden stops or lane shifts.
