Listing of updates to the New Jersey Graduated Driver License:
November 9, 2015: T Restriction
Regulations require that a Z restriction be used on commercial driver licenses to designate “No Full Air Brake”. Therefore, the current Z restriction that appears on NJ Graduated Driver Licenses (GDL) will be changed to a T restriction. All GDL licenses issued up to and including November 7, 2015 will continue to have the Z restriction printed on them and will remain valid until their expiration date.
