What it means
The S-321 sign informs of places of interest by motorway or dual carriageway. It guides toward tourist, cultural, natural, or service destinations accessible from a high-capacity road, normally through a signed exit or itinerary. It does not require you to exit or authorise sudden lane changes to follow the indication. It usually appears before links or exits where those places can be reached with enough advance notice. When you see it, decide whether it matches your route, occupy the appropriate lane, and keep attention on fast traffic. In the test it is often distinguished from the equivalent on conventional roads and from ordinary service signs.
