I think the only way you can 'prove' it is to apply for Slovenian E-Vignette here.I don’t want to doubt you, but can you provide evidence that for sub 7.5t but over 3.5t this is the case, it would be really helpful as at 5 tons I’ve danced round the roads in Slovenia without getting the Darsgo box for the motorways
Maybe go through the entire process, but don't actually pay up.
We are over 3.5t (but not by much, and we look like any other German MoHo with a 3.5t limit)
I filled in the night before.
Which I seem to remember is the earliest you can fill it in as you can only defer until the next day.
(Edit, you can now apply up to 30 days before)
I agree, it does now seem to exclude vehicles over 3.5t
However if I enter my vehicle as a Mercedes Sprinter, I get told it's a type '2B'
