What do construction and maintenance signs notify drivers of?

Answer: D — Possible danger in or near work areas, diamond-shaped signs, cones, drums, and barricades

Construction and maintenance signs are all about warning you there could be danger or changes in traffic flow in a work zone. They’re typically orange and often diamond-shaped, with cones, drums, and barricades marking the area. This combination signals you to slow down, use caution, and obey any directions from workers or temporary signals. The purpose is to alert you to hazards such as workers on or near the roadway, changing lanes, narrowed lanes, or detours, so you can navigate safely. Other signs indicate things like the end of a road, speed limits, or the location of rest areas, which aren’t specifically about hazards in work zones.
