Truck Tolling Systems: Types and How They Work

A truck tolling system is the method a country uses to charge lorries for using its roads, bridges and tunnels. Europe uses several models, which differ in how they work: how the charge is calculated and how it is collected. A single international tour often crosses more than one of them.

Main types of tolling system

• Free-flow: gantries and on-board units charge vehicles automatically at motorway speed, with no barriers.
• Closed systems: the truck is registered when it enters the motorway and pays at the exit for the distance driven in between.
• Open systems: toll stations on the road charge a fixed amount for each section, whatever the length of the journey.
• Vignette: a time-based pass (such as the Eurovignette) that allows road use for a fixed period rather than per kilometre.

The difference matters for costing. Free-flow, closed and open systems charge per kilometre or per section, so the toll belongs to the cost of each tour. A vignette is paid per period, whether the truck uses the road once or every day, so it behaves more like a fixed cost per truck.

How tolls are calculated

Charges usually depend on the distance, the number of axles, the weight class and the Euro emission class of the vehicle. Since the EU's Eurovignette Directive was amended by Directive (EU) 2022/362, the CO2 emission class counts as well: member states have to vary truck charges by CO2 class, from class 1 for conventional trucks to class 5 for zero-emission vehicles, or charge CO2 emissions separately as an external cost. Which vehicles pay is decided nationally. In Germany, for example, the toll on motorways and federal roads applies to goods vehicles with a technically permissible maximum mass of more than 3.5 tonnes. Because rates vary by country and road, dispatchers estimate them in advance with the IMPARGO toll calculator to price and plan routes accurately.

Tolls on cross-border tours

Each system needs its own preparation. A free-flow toll usually requires an on-board unit or a registration before the first tolled kilometre, a vignette has to be booked for the right period before the truck reaches a charged road, and closed systems need a payment method at the exit. To cut the number of devices in the cab, the EU's European Electronic Toll Service (EETS) lets a provider offer one contract and, where needed, one on-board unit for the toll domains of several countries.

The mix is also changing. Under the same 2022 amendment, member states may no longer charge heavy-duty vehicles time-based user charges on the core trans-European transport network from 25 March 2030, except in duly justified cases. The Netherlands, for example, left the Eurovignette on 1 July 2026 and now charges trucks per kilometre. A route that was cheap last year can therefore cost more today, which is why current toll rates belong in every quote rather than in an old rate card.
