Conn. Agencies Regs. § 14-67d-5
A licensed manufacturer or "bona fide full-time employee" of such licensed manufacturer may operate a motor vehicle displaying such general distinguishing registration plates in connection with the business of manufacturing or distributing motor vehicles and for his or her personal use. No commercial motor vehicle displaying such general distinguishing registration plates shall be operated on the highway while carrying a load except for demonstration purposes. "Bona fide full-time employee" means a person who is employed by a licensed manufacturer for not less than thirty-five hours per week and appears on the records of such employer as an employee for whom social security, withholding tax and all deductions required by law have been made. If the licensee is a corporation, a motor vehicle displaying such general distinguishing registration plate may be used by any corporate officer actively engaged in the management of the corporation, just as if the officer were an individual licensee.
