Which statement best describes construction or temporary signs?

• A. They indicate route information
• B. They indicate parking restrictions
• C. They indicate school zones
• D. They indicate construction or temporary conditions

Answer: (D)

Signs used in work zones alert drivers to temporary conditions ahead, such as lane closures, detours, or reduced speeds. They’re meant to be seen quickly so you can adjust your driving to the current, not permanent, setup. That’s why the statement describing construction or temporary conditions is the best description. Other signs focus on different information: route signs guide you to destinations, parking signs tell you where you can or can't park, and school-zone signs warn about school areas and related speed limits.
