I'm a bit late, but you can use some custom POIs for that.
Spoiler: Download and extract to your content folder
Activate the height restrictions POIs and they will show up as a road sign on the map no matter what vehicle profile you selected. There is some other stuff in there like tunnels, truck, bus parking places, etc. Activate what you need. I hope you don't mind that they are in Macedonian. They should be precise enough but I am not resposible for any incorrect info![]()
