Who has the authority to establish a work zone?

The authority to establish a work zone is vested in any governing authority. This includes state and local government entities that oversee public safety and infrastructure. Governing authorities are responsible for ensuring that work zones are set up in compliance with regulations that promote safety for both workers and motorists. They have the proper jurisdiction and legal framework to implement necessary measures, such as signage, traffic control, and barriers, to alert the public of roadwork and potential hazards.

While traffic police may enforce laws and regulations in these areas, they do not have the authority to create work zones independently. Local citizens do not have the power to establish work zones; their role is typically limited to supporting or raising awareness about road safety. Road construction firms may play a crucial role in the physical establishment and maintenance of work zones, but their operations must be authorized and guided by governmental regulations and standards. Thus, the correct answer represents the formal power and responsibility that governing authorities have in establishing work zones to ensure public safety and order.
