The director of vehicles is likewise empowered and authorized to confer, advise with, and enter into such interstate contracts and agreements and make such declarations as he or she may deem proper, expedient, fair and equitable to this state or the citizens thereof with legislative bodies, commissions, boards or officials duly authorized and empowered by the law of any other state, or addressed to any other state in the case of declarations, with the view of promoting and establishing such fair, just and equitable interstate agreements, arrangements or declarations for the licensing, movement, taxing, registration, regulation and fees to be charged therefor of vehicles licensed in this state and operated on the highways of some other state, and those owned and licensed in some other state and operated on the highways of this state.
If another state has a law or statute which contains a reciprocal interstate provision for the benefit of this state, or vehicles or owners of vehicles licensed in this state, then the director of vehicles, if he or she be of the opinion that it would be beneficial to this state or the citizens thereof, is authorized to issue a declaration of interstate reciprocity or proportional licensing upon terms specified by the director, and to notify the proper authority of such other state thereof. No interstate contract, agreement or declaration made under authority of this act shall be valid unless approved by the governor of this state. A copy of all agreements, arrangements and declarations made by the director of vehicles shall be filed with the revisor of statutes. Any agreement, arrangement or declaration entered into or issued under authority of this act may specify either residence or base as a determining factor for rights or privileges granted, or may specify any other factor or combination of factors for making such determination.
