What is the purpose of an orange warning sign?

The purpose of an orange warning sign is to indicate temporary traffic control situations. These signs are typically used in construction zones, maintenance areas, or any other situation where road work is occurring. They serve to alert drivers that they need to proceed with caution due to changing conditions, potential hazards, or altered traffic patterns ahead. In essence, these signs are critical for ensuring the safety of both workers and motorists by prompting drivers to be aware of their surroundings and adapt accordingly when navigating through or near work zones.

Other options relate to specific types of signs like stop or prohibition signs that indicate mandatory actions, regulation signs that provide specific legal instructions, and general warning signs that alert drivers to potential dangers. However, an orange warning sign specifically focuses on temporary situations in the traffic environment, making it essential for maintaining safety during road work operations.
