(c) The following vehicles are exempt from payment of a user fee:

(d) The department may, subject to approval of the board, prohibit certain classes of vehicles from operating in a user fee facility through the posting of appropriate signage, wherever the department determines, on the basis of an engineering and traffic investigation that the presence of those vehicles impairs the safe or efficient operation of the user fee facility.

(e) A person who uses a user fee facility and fails to pay the user fee within ninety (90) days of the person's notice of nonpayment under § 54-3-114, or a person who operates a prohibited vehicle on a user fee facility, commits a Class C misdemeanor and is subject to a fine of not more than fifty dollars ($50.00).
