The road has a severe bug related with it. The Basic road object is broken, so vehicles drive on them while their wheels clip through the road.

I see. I will try that

@Brrnout only way to fix it is to set other road to main road or to ban traffic with a "zoned neighborhood with ban traffic settings". I use the same parameter as the bus lane in the game. In-game with vanilla bus lane w/ 4 or 6 lane road, car still using bus lane to make right or left turn too This road item keeps your game "vanilla"

Cars are randomly going down the lane

This does not work :(

doesn't work without DLCs

Is After Dark required?

@Sauber i know, but i use the exact same settings than bus lane in-game :/ the only fix that i found is to set the nearest road to "Main Road" to force the traffic to not use it.

All cars use it by me. Can you change that, so no private cars use it ?! Or need definitely a road-mod for that? (I haven't.)

Bei mir nutzen alle Fahrzeuge diese Straße. Kannst du das ändern, sodaß keine Privatfahrzeuge sie nutzen ?! Oder brauch man dafür unbedingt eine Straßen-Mod? (Ich nutze keine.)
