What role do temporary road signs play in traffic control?

Temporary road signs are crucial in managing traffic and ensuring safety in work zones. Their primary function is to communicate essential information to drivers about changing conditions, guiding them safely through or around construction areas. This includes indicating detours, warning of hazards, and advising on reduced speed limits. By effectively directing traffic, temporary signs help minimize confusion and enhance the overall safety of both drivers and workers present in and around the work zone.

While options that suggest advertising local businesses, providing entertainment, or simply marking the end of a work zone might seem relevant in some contexts, they do not encapsulate the primary purpose of temporary road signs. Their focus is strictly on traffic management and safety, underscoring the importance of proper signage in the planning and execution of roadwork to protect all road users.
