Jest odpowiedź, ale jak dla mnie nie wyjaśnia zbyt dużo...
You need a vignette as soon as you come on the motorway or on the highway ((A1, A2, A3, A5, H2, H3, H4, H5, H7), at once after border. The only exeption is Karawanken tunnel. If you pass through Karavanken tunnel you must pay a vignette for using motorway from the first junction (Hrušica) in direction to Ljubljana. For Karawanken tunnel, which is not included in vignette sistem you must pay extra toll. So, if you leave motorway on first junction after Karavanken tunnel (Hrušica), you just pay a toll for tunnel and you don't need a vignette. If you countinue your trip on motorway after Hrušica, you must have a vignette. The same is if you come on the motorway on junction Hrušica and you go towards Karavanken tunnel.
Wychodziłoby na to, że jest zjazd na węźle Hrusica...ale gdzie?
