I can only see a 60 sign at the start of the link https://www.mapillary.com/app/?lat=-27.663581886206885&lng=152.73979205152136&z=17&x=0.49548370263958935&y=0.50767663189853&zoom=0&pKey=B-1LcWLyCAjIQqhNjTQ7AQ, & speed then jumps to 100 just before merging out onto the Cunningham Highway > > 1. maxspeed=80 represents the speed limit of the trunk way from which > the motorway link leaves. > > Welcome to Australian roads! Just because it's a trunk road, doesn't necessarily mean it's got an appropriate speed limit :-( > > 1. nothing until the SL100 sign but maxspeed=100 starting with the > appearance of the sign in the field? > > 60, not "nothing" between the 2 signs, then 100. Hope that helps! Thanks Graeme
