What happens without a valid vignette?

How do checks on a valid vignette work?

In all 9 countries, checks are largely automated, via ANPR cameras (automatic number plate recognition) mounted above or beside the motorway. Every passing license plate is photographed and instantly compared against the database of registered vignettes. If there's no valid registration, this is flagged for further handling. In most countries, additional random checks are also carried out by police or a separate enforcement service along the road, for example at border crossings or specific checkpoints.

Unlike a barrier toll gate, a digital vignette system has no stopping point: you won't notice the check at all while driving. That also means a missing vignette only becomes apparent afterwards, through a fine or, in some countries, an on-the-spot warning during a police check.

What kind of fines can you expect?

The exact amounts differ by country and can change over time. In every case, assume that driving without a vignette will cost you considerably more than buying the vignette in advance. For a number of countries, more concrete figures are known:

Country	What you roughly risk
Austria	A replacement toll (Ersatzmaut) well above the vignette price for the relevant category, with an additional administrative fine if payment isn't made on time, which can add up considerably.
Switzerland	An on-the-spot fine of CHF 200, plus having to buy the vignette itself (CHF 40) anyway.
Slovenia	A fine starting at roughly € 300, sometimes with a discount for prompt payment, and considerably higher than in some neighbouring countries.
Hungary	If you enter the motorway without an e-matrica, a short grace period of roughly 60 minutes usually applies to still buy a vignette before a fine becomes final. Miss this window, and you risk a substantial fine that grows the longer payment is delayed.
Czechia	A fine considerably higher than the vignette price itself; the exact amount may change.
Slovakia	A fine that can add up; usually lower if paid on the spot than if the case is handled administratively.
Bulgaria	A fine that can run to several hundred euros, often with the option to pay a reduced compensation amount the same day.

Amounts and procedures may change. This overview gives an indication based on the most recent information available. If in doubt, always assume the highest estimate, and buy your vignette in advance regardless.

Why ordering on time matters so much

For most vignettes this is simple: buy it before you set off, and you're covered. For a few validity periods it's more nuanced, because the statutory 14-day cooling-off period that applies to every online purchase within the EU also applies to vignettes.

The same principle applies in other countries too: the shorter your validity period, the more likely it's active immediately after purchase, but always check this at the time of ordering. Especially for a planned trip, it's wise to arrange your vignette at least a few weeks ahead, so any waiting periods don't catch you out and you never risk crossing the border without a valid registration.
