The State may impose any requirements it believes is necessary to ensure itself that a driver is properly trained pursuant to § 172.704 of this title.
(iii) A restricted CDL document issued pursuant to this paragraph shall have a statement clearly imprinted on the face of the document that is substantially similar as follows: “For use as a CDL only during the period from June 30 through July 6 for purposes of transporting less than 227 kilograms (500 pounds) of fireworks classified as DOT Class 1.3G explosives in a vehicle with a GVWR of less than 4,537 kilograms (10,001 pounds).
