(a) The Traffic Committee by resolution or order entered in its minutes may regulate or prohibit the use of any controlled-access highway by any class or kind of traffic which is found to be incompatible with the normal and safe movement of traffic.

(b) The Traffic Committee adopting any such prohibition shall erect and maintain official traffic-control devices on the controlled-access highway on which such prohibitions are applicable and when these are in place, no person shall disobey the restrictions stated on such devices.

(c) The Traffic Committee may authorize the stopping of a school bus on a controlled-access highway to pick up or discharge passengers, except the National System of Interstate and Defense Highways, if after a traffic and engineering study they determine that there is no viable alternative and that adequate safety, both for the passengers, school bus, and other highway users, can be maintained.
