AUTOCYCLE plates first appeared in October 2017.
These are for 3-wheeled motorcycles and are the same size as regular motorcycle plates.

Numbering uses an alternating alpha-numeric pattern A0A0A (the opposite of moped plates which are 0A0A0) and probably started at A1A1A.

ALPHA KAPPA ALPHA plates also first appeared in October 2017.
These are for the Alpha Kappa Alpha Sorority, and they are the first fraternity/sorority plate issued in New Jersey.

The IV prefix refers to their Ivy Leaf symbol which appears on the plate.
