What is the primary purpose of construction signs in work zones?

Answer: B — To warn of potential hazards

The primary purpose of construction signs in work zones is to warn of potential hazards. These signs alert drivers and pedestrians to the presence of construction activities, which can pose various risks, such as uneven surfaces, construction vehicles, or workers present in the area. By providing this warning, the signs help to enhance safety for both road users and construction personnel. While informing about detours, advertising road services, and indicating speed limits are important functions of roadway signage, the essence of construction signs is fundamentally rooted in cautioning drivers about immediate dangers that could impact their safety. This focus on hazard awareness is crucial in fostering a safer environment in active work zones, where conditions may change rapidly and where vigilance is necessary to prevent accidents or injuries.
