If a vehicle is permanently withdrawn from a proportionally registered fleet and a replacement vehicle is added to the fleet in the same calendar month, the replacement vehicle shall be considered fully registered as provided in Section 1133 of this title and Section 14-109 of this title, if the replacement vehicle is registered for a weight equal to or less than the vehicle permanently withdrawn, or if additional registration fees are paid when the replacement vehicle is registered for a weight greater than the vehicle withdrawn. If a vehicle is permanently withdrawn from a proportionally registered fleet and is not replaced by another vehicle in the same calendar month, credit shall be allowed as otherwise provided in this section.
The Corporation Commission shall have the authority to promulgate rules which provide procedures for implementation of comparable regulatory fees and taxes for vehicles used in this state by residents of other states.
Any revenue derived from this subsection shall be apportioned in the same manner as provided in Section 1104 of this title.
It is the intention of the Legislature that the motor vehicle registration and licensing fees assessed against residents of other states operating similar vehicles in Oklahoma be comparably the same as the motor vehicle registration and licensing fees assessed against residents of Oklahoma operating a similar vehicle for a similar purpose in such other state; and that the Corporation Commission diligently monitor the motor vehicle registration and licensing fees assessed against residents of Oklahoma by other states and to provide for uniform treatment of Oklahoma residents operating vehicles in other states and for residents of other states operating vehicles in Oklahoma.
