(a) When a resident carrier of this State interchanges a properly licensed trailer or semitrailer with another carrier who is a resident of another state, and adequate records are on file in his office to verify such interchanges, the North Carolina licensed carrier may use the trailer licensed in such other state the same as if it is his own during the time the nonresident carrier is using the North Carolina licensed trailer.

(b) Motor vehicles duly registered in a state or territory which are not allowed exemptions by the Commissioner, as provided for in the preceding paragraph, desiring to make occasional trips into or through the State of North Carolina, or operate in this State for a period not exceeding 30 days, may be permitted the same use and privileges of the highways of this State as provided for similar vehicles regularly licensed in this State, by procuring from the Commissioner trip licenses upon forms and under rules and regulations to be adopted by the Commissioner, good for use for a period of 30 days upon the payment of a fee in compensation for said privilege equivalent to one tenth of the annual fee which would be chargeable against said vehicle if regularly licensed in this State: Provided that only one such permit allowed by this section shall be issued for the use of the same vehicle within the same registration year. Provided, however, that nothing in this provision shall prevent the extension of the privileges of the use of the roads of this State to vehicles of other states under the reciprocity provisions provided by law: Provided further, that nothing herein contained shall prevent the owners of vehicles from other states from licensing such vehicles in the State of North Carolina under the same terms and the same fees as like vehicles are licensed by owners resident in this State.

(c) Every nonresident, including any foreign corporation carrying  on business within this State and owning and operating in such business any motor vehicle, trailer or semitrailer within this State,  shall be required to register each such vehicle and pay the same fees  therefor as is required with reference to like vehicles owned by residents of this State.
