Two license plates shall be issued for every motor vehicle, except that one plate shall be issued for dealers, motorcycles, minitrucks, truck-tractors, trailers, buses, apportionable vehicles, and special interest motor vehicles that use the special interest motor vehicle license plate authorized by and issued under section 60-3,135.01. The license plates shall be of a color designated by the director. The color of the plates shall be changed each time the license plates are changed. Each time the license plates are changed, the director shall secure competitive bids for materials pursuant to sections 81-145 to 81-162. Motorcycle, minitruck, low-speed vehicle, and trailer license plate letters and numerals may be one-half the size of those required in this section.
(2) When two license plates are issued, one shall be prominently displayed at all times on the front and one on the rear of the registered motor vehicle or trailer. When only one plate is issued, it shall be prominently displayed on the rear of the registered motor vehicle or trailer. When only one plate is issued for motor vehicles registered pursuant to section 60-3,198 and truck-tractors, it shall be prominently displayed on the front of the apportionable vehicle.
