(c) Upon submission of the renewal of registration form and payment of normally required fees, the license plates, decals, and registration cards issued pursuant to this section for the vehicle shall remain valid; provided that a fleet vehicle registered under this section may be deleted from such identified fleet upon notification of the director of finance by the registered owner on the proper form, and if the distinguishing license plates, decals, and registration cards issued for the vehicle are surrendered. Failure to comply with the preceding sentence shall require payment by the fleet owner of fees due for registration of the vehicle as though the vehicle remained part of the fleet. Display of the distinguishing license plate or decal and registration card shall constitute prima facie evidence that the vehicle is currently registered. The registered owner or lessee of any vehicle registered pursuant to this section shall display in a conspicuous place on both the right and the left side of each vehicle, the name, trademark, or logo of the company. The display of the name, trademark, or logo shall be printed in sharp contrast to the background of the vehicle and shall be of such size, shape, and color as to be readily identifiable during daylight hours from a distance of fifty feet.
