Before a temporary regulatory sign can supersede an existing regulatory sign, what must be obtained?

For a temporary regulatory sign to supersede an existing regulatory sign, it is essential to obtain authorization from the governing jurisdiction. This is crucial because regulatory signs play a significant role in ensuring public safety and traffic management, and any changes to them need to be carefully considered and sanctioned by the appropriate authorities. Without the governing body's approval, there may be legal liabilities or confusion among drivers regarding which signs are in effect.

In the context of traffic management, governing jurisdictions have established procedures and criteria to ensure that all regulatory changes, including the installation of temporary signs, conform to local laws, standards, and practices. This ensures that signage remains consistent and reliable for the safe navigation of motorists and pedestrians.

While public approval, an emergency response plan, and a traffic study report may be relevant in certain contexts regarding traffic control or safety, they are not prerequisites for a temporary sign to take precedence over an existing one. The authorization from the governing jurisdiction is the definitive requirement to proceed with these changes.
