What is the difference between interstate commerce and intrastate commerce?
Interstate commerce is trade, traffic, or transportation involving the crossing of a State boundary.
Either the vehicle, its passengers, or cargo must cross a State boundary, or there must be the intent to cross a State boundary to be considered an interstate carrier.
Intrastate commerce is trade, traffic, or transportation within a single State.
If your operations include interstate commerce, you must comply with the applicable Federal safety regulations and Operating Authority rules, in addition to State and local requirements. You must notify the State in which you plan to register your vehicle(s) of your intentions to operate in interstate commerce to ensure that the vehicle is properly registered for purposes of the International Registration Plan (IRP), and International Fuel Tax Agreement (IFTA). The base State will help you by collecting the appropriate fees and distributing a portion of those fees to the other States in which you operate commercial motor vehicles.
If you operate exclusively in intrastate commerce , you must comply with applicable State and local regulations. The only Federal regulations that are applicable to intrastate operations are: the commercial driver’s license (CDL) requirement, for drivers operating commercial motor vehicles as defined in 49 CFR 383.5; controlled substances and alcohol testing for all persons required to possess a CDL; and minimum levels of financial responsibility for the intrastate transportation of certain quantities of hazardous materials and substances.
