Which items are commonly used in conjunction with construction signs to guide drivers safely?

Cones, drums, and barricades are commonly employed alongside construction signs to ensure the safety of both drivers and construction workers. These items serve various purposes in traffic management during construction activities:

• Cones are used to delineate lanes, guiding vehicles safely around work zones and ensuring they do not enter restricted areas.
• Drums provide a more substantial, visible barrier that can be seen from a distance, offering clear guidance to motorists navigating through or around construction sites.
• Barricades serve as physical barriers that can prevent access to dangerous areas, such as open pits or zones where heavy equipment is operating.

This combination helps to draw attention to the construction signs, ensuring that drivers are aware of the changing conditions ahead, thereby minimizing accidents and enhancing overall road safety.
