(A) (1) Each school bus and multifunction school-activity bus shall display at the rear of the bus a sign, with letters and numerals readily visible and readable, indicating the area code and telephone number of the owner of the bus, regardless of whether the owner is a school district or another person or entity. The sign shall be in the following form:
“TO COMMENT ON MY DRIVING, CALL (area code and telephone number of bus owner).”
(2) A school bus owner who placed a sign conforming to the requirements of Public Act 95-176 on a school bus before January 1, 2010 (the effective date of Public Act 96-655) may continue to use that sign on that school bus rather than a sign that conforms to the requirements of Public Act 96-655; however, if the school bus owner replaces that sign, the replacement sign shall conform to the requirements of Public Act 96-655.
(B) The owner of each school bus or multifunction school activity bus shall establish procedures for accepting the calls provided for under division (A) above and for taking complaints.
(C) The procedures established under division (B) above shall include, but not be limited to:
(1) An internal investigation of the events that led to each complaint; and
(2) A report to the complaining party on the results of the investigation and the action taken, if any.
