What it means
The S-355 sign is placed over the carriageway on a motorway or dual carriageway and indicates an immediate exit toward a motorway or dual carriageway. It links the signed lane with the exit path, so you must read it as lane and destination guidance at a nearby decision point. It usually appears at links where a high-capacity road connects with another of the same or similar type. When you see it, confirm your destination, occupy the corresponding lane safely, and do not cross markings or lanes late. In the test they often ask that the exit is immediate and that the sign is located over the carriageway.
