Do oversize travel hours rules differ by state?

Yes. When a permitted oversize load may move here Crosstatelaws maps all 50 states for travelers who are physically in that state — not for what a state requires of its own plates or licenses.

Does oversize travel hours apply if my vehicle is registered in another state?

Operate-here rules (speed, helmets, possession, inspections you must stop for) follow the state you are in. Registration-state rules such as a front license plate do not. Read the layer notes on the map.
