N.D. Cent. Code § 39-04-55
The registration issued for a vehicle must be in the driver's vehicle or on an electronic device in the possession of the driver or, in the case of a housetrailer or mobile home or a trailer or semitrailer, regardless of when such vehicle was acquired, inside or on the vehicle, at all times while the vehicle is being operated upon a highway in this state. The registration is subject to inspection by any peace officer or highway patrol officer. Upon request of an inspection by any peace officer or highway patrol officer, a driver may produce either a registration card or electronic registration as provided by the department. An electronic registration must be designed so that there is no need for the registration holder to relinquish possession of the device, in which the electronic registration is installed, to present the registration, or for the individual to whom the registration is presented to access the verification system to confirm the validity of the registration. Any person violating this section must be assessed a fee of twenty dollars. However, a person cited for violation of this section may not be found to have committed the violation if the person, within fourteen days after being cited produces and displays to the office of the prosecutor where the matter is pending, a registration valid at the time the person was cited. A peace officer or highway patrol officer, upon citing a person for violating this section, shall inform the person that a violation will be considered as not having occurred if the person produces and displays a valid registration in the manner provided in this section.
