The registration of a vehicle shall expire at midnight on the last day of the period for which it is registered, and the vehicle shall not thereafter be operated upon the highways of this State until it has been reregistered according to law. This section shall not apply to the vehicles registered under the International Registration Plan or to vehicles registered under temporary or limited permits or certificates as otherwise provided by this title.(b) The owner of any semitrailer or trailer who wishes to match that vehicle's license plate expiration with the towing vehicle's license plate expiration may register such semitrailer or trailer for a period of from 1 to 12 months.

Newly-manufactured previous model year motor vehicles or trailers having the above criteria may initially be registered for 6 years or less by a prorated formula established by the Division of Motor Vehicles. The effective date of registration shall be the date the vehicle is titled. The registration fee shall be the number of years selected multiplied by the annual registration fee. Thereafter, the registration shall be renewed pursuant to § 2110 of this title.(d) In calculating the prorated fees or combined annual fees payable pursuant to this section, the fees shall be calculated using the rates in effect or scheduled to be in effect during the period of the prorated or extended registration.Amended by Laws 2017, ch. 184,s 1, eff. 9/21/2017.36 Del.
