You pass through one set of signals when you cross the oncoming traffic lanes, and another set when completing the turn onto the cross street, so I would probably describe it as "turn slightly left at the first traffic signal, go (distance) and turn left onto (street) at the second signal". I tend to err on the side of tagging every node where traffic might possibly stop for a red light, and there isn't a good way at the moment to indicate that there are two or more nodes tagged with highway=traffic_signal but only one set of signals. -- David J.
