In the US, there are several different types of public roads that are normally indicated on the road itself by shield insignia. E.g. a red-white-and-blue stylized shield for Interstate Highways, a white one for US Highways (e.g. US Route 1), and a smorgasbord of State, Territory, or Local insignia (e.g. Virginia has at least two shield shapes that indicate something). I’ve also seen this type of thing in Canada, but am not really familiar with it. I’ve driven on the Trans-Canadian Highway which I believe is Federal and also some Provincial or local roads.
I understand that these designations have something to do with how the road is funded. E.g. federal roads may be maintained with Federal money, while state roads are the state’s responsibility.
I am aware of “limited access highways” and how that affects the rights of adjoining property owners to build a driveway or parking lot off the road.
Other than speed limits, does the designation of a road affect rights in any significant way, or does it affect the jurisdiction of legal issues that arise over use of the road? Feel free to respond with your favorite jurisdiction, wherever it is in the world.
E.g.:
“In <State> it’s illegal to use a cell phone while driving on a State Primary Route, State Secondary Route, or County Route. You can, however, use them on US Highways and Interstates because of some weird jurisdictional matter <or something else…>.”
or
“At least the accident occurred after I got off of US 30 and had already made it fully onto State Route 87. Otherwise, we would have to have the injury case go through Federal Court and pay through the nose for an attorney who is familiar with their procedures.”
