Final answer:
When no waiver has been granted, national regulations should be prioritized, with local guidelines and operational necessity considered as secondary factors. Disagreements and inconsistencies can arise from the varied application of laws across different jurisdictions.
Step-by-step explanation:
In cases where a waiver has not been granted, national regulations should be considered. These regulations prefer policies set at the national level and opt for standards of consistency across state and local governments. Considering local guidelines and operational necessity may also be important, but when no waiver is present, national regulations often take precedence.
Public policies and decision-making processes are influenced by different points of view on local, state, national, and international levels as per guideline WG.15A. These differing viewpoints result in a diversity of regulations and their application. However, the lack of uniform application can cause disparities which can lead to disagreements and sometimes litigation, emphasizing the importance of adhering to national regulations when waivers are absent.
