text: This roundabout may not be part of trunk road D424 surely not with motorroad=yes as it isn't separated from other traffic and anyone (even pedestrians) can enter it via the port service roads and Gaženicka cesta.
  
  Also, it can be seen on Mapillary (https://www.mapillary.com/app/?lat=44.09185555555556&lng=15.263116666666667&z=17) that the trunk way starts on road https://www.openstreetmap.org/way/294151987 (the traffic sign with car symbol in blue square), not on the roundabout.
  
  Or is there any official road database of Croatia that designates also the roundabout as trunk road with restricted access (as motorway, thus motorroad=yes)? But those restrictions aren't signposted or enforced in reality.
