How can you identify a road work zone?

Identifying a road work zone primarily involves recognizing specific indicators that signal construction activities. Construction signs are placed to alert drivers about the upcoming work zone and typically display warnings regarding reduced speed limits, lane closures, or detours. Additionally, the presence of cones further delineates the work area and helps guide vehicles safely around the construction zone. Flaggers are often employed to manage traffic flow and provide directions to drivers, making their presence a clear sign of road work. These elements work together to ensure that drivers are aware of potential hazards and that they can navigate the area safely.

Other options, while they may pertain to road safety, do not provide the same direct indicators of a work zone. Simply following posted speed limit signs is necessary for safe driving but does not inherently indicate a work zone. Watching for pedestrians is important for maintaining pedestrian safety, especially in urban areas, but it is not a specific indicator of construction activities. Likewise, observing the color of the road surface may give clues about road conditions but does not offer any overt signs that there is work underway. Therefore, the combination of construction signs, cones, and flaggers makes option A the most accurate way to identify a road work zone.
