The photos are not zoomable, and GSV latest is 2022, so out-of-date, but from the little I can see, the signs are absurdly high, looks like 3 metres which is really outrageous, being well outside the normal viewing span of a motorist looking out for hazards in a big city. However, with no good photo, it would be best if you could do some legwork and take photos, and if you can, measure the height the bottoms of the signs are from the pavement. There seem to be no text panels below the "Flying Motorbike" signs so they apply 24x7.
