What type of ordinance is a local authority prohibited from enacting?

Local authorities are prohibited from enacting any ordinance that conflicts with Title 28 provisions because Title 28 typically refers to specific statutes or uniform codes regarding transportation and vehicle regulations. This prohibition ensures consistency and uniformity in the application of traffic laws across jurisdictions. If local ordinances were allowed to contradict these established regulations, it could lead to confusion and inconsistency in enforcing traffic laws, ultimately undermining public safety and compliance.

The other types of ordinances listed, such as those regarding parking regulations, noise regulations, and environmental control, can often be established by local authorities, provided they do not contradict higher laws or state statutes. Therefore, while local entities have the authority to govern many local issues, they must do so within the framework of state laws, and any conflicting ordinances with Title 28 would override local provisions.
