LiAZ-677Sh (conditional index) is a staff bus based on the excursion LiAZ-677V, designed for law enforcement officers involved in various cultural events. The headquarters modification was distinguished from the base LiAZ-677 by the presence of one hinged front door on the right, the rear door was absent (as on the LiAZ-677V sightseeing bus) and, of course, the difference was in the interior of the cabin; the headlights of the LiAZ-677Sh were square. Staff buses were assembled piece by special order.
