Slovenia has no toll booths for cars. Instead, every motorway and expressway journey requires a vignette, and since the switch to the electronic system there is no sticker to attach — the e-vignette is tied to your registration plate and checked by camera.
You buy it by entering the number plate and country of registration, and you choose the start date. Nothing needs to be printed: enforcement uses automatic plate recognition at fixed gantries and by mobile patrols. Driving without a valid vignette leads to a substantial on-the-spot fine.
Cars up to 3.5 tonnes fall into category 2B, with weekly, monthly and annual options. Motorcycles have their own cheaper category. Vehicles taller than 1.3 metres at the front axle — which includes many camper vans — fall into a more expensive class, so check your registration document before buying.
For a short holiday the weekly vignette is normally the right choice; if you cross Slovenia several times a year on the way to Croatia, a monthly or annual one pays for itself quickly.
The official channel is the DARS online shop run by the Slovenian motorway operator, where you pay the vignette price with no surcharge. You can also buy at petrol stations near the border, at kiosks and at post offices. Private online resellers add a service fee on top.
Even with a valid vignette, leaving the motorway to refuel is worth it: the price difference is almost always bigger than the few minutes you lose. The live map shows which exit to take.
