The main idea here is who has the primary legal authority to regulate and oversee roads and public transportation in the United States. That authority largely rests with state governments. States run the show through their departments of transportation, setting highway design and safety standards, traffic laws, licensing, and funding decisions that guide how most roads and intercity or regional transit systems operate within the state. They also coordinate with local jurisdictions to ensure consistency across the state.

Local governments do play a crucial role because they own and maintain many local streets and operate some local transit services. But their authority typically comes from state law, and they work within the framework and funding provided by the state. The federal government influences transportation mainly through nationwide safety standards and funding programs, not by owning or directly controlling the bulk of roads and transit.

So, while local and federal roles matter, the fundamental legal authority for most roads and public transportation is held by state governments.
