Important changes to road toll systems in Europe – what do hauliers need to know?

Over the coming month, major changes to truck toll systems will take effect in several European countries. The new regulations include higher fines, an expanded toll road network, updated tariffs, and the introduction of CO₂ emission classifications.

Belgium: New rates in Flanders and Brussels from 1 July 2025

From 1 July, updated toll rates for trucks will apply in Flanders and Brussels. The indexation will affect all vehicles over 3.5 tonnes subject to the Viapass system.

The toll rates depend on the permissible gross vehicle weight (three bands: 3.5–12 t, 12–32 t, and over 32 t) and the vehicle’s emission class – from Euro 0 to Euro 6. Zero-emission vehicles (ZEVs) will continue to benefit from a 0 cents/km rate, provided they are equipped with an active OBU device.

In Wallonia, toll rates will remain unchanged, having already been updated earlier this year.

Denmark: Increased fines and the risk of being stopped at the Storebælt Bridge

Under amendments adopted by the Danish Parliament at the end of April, the fine for non-payment of road tolls has doubled from DKK 4,500 to DKK 9,000 (approx. €1,206). Notably, only one fine per day can be issued per vehicle.

A new regulation allows trucks to be physically stopped before crossing the Storebælt Bridge. If the system detects unpaid tolls, the driver will have to pay on the spot or turn back. The system uses automatic number plate recognition, and any violations are reported to the police.

Since the launch of the KmToll system in January 2024, hauliers have reported numerous technical issues and incorrect penalties. The Danish transport association ITD advises companies not to pay unjustified fines, as these can be postponed until the conclusion of appeal or court proceedings.

Although authorities announced that unpaid fines could lead to the automatic seizure of trucks from 1 July 2025, in practice this process may take several years. The Danish DTL organisation emphasises that only a final court ruling can trigger enforcement.

Lithuania: Toll road network extended by 1,151 km from July 2025

The Lithuanian government has announced the expansion of the toll road network to include 21 additional regional road sections. From 1 July 2025, the total length of tolled routes will reach 2,851 km.

The new sections – including routes such as Kaunas–Alytus, Šiauliai–Pasvalys, and Biržai–Panevėžys – will apply only to commercial transport of goods and passengers. Private vehicles will remain exempt.

The main objective of the reform is to improve road quality, as currently only just over half meet technical standards. According to the Lithuanian agency Via Lietuva, toll revenues are expected to rise to €77 million in 2026.

Slovakia: CO₂-based toll rates from 1 July 2025

Slovakia’s toll system will be aligned with the EU Eurovignette Directive. From 1 July 2025, all vehicles will be assigned to one of five CO₂ emission classes – from CO₂ Class 1 (highest rate) to CO₂ Class 5 (zero-emission vehicles).

Vehicles registered before 1 July 2019 will automatically be placed in CO₂ Class 1, unless they are electric or hydrogen-powered. Newer vehicles may apply for a more favourable classification by submitting relevant documents (COC, CIF, registration certificate details) via the website www.emyto.sk, email, or post.

This process is voluntary and does not involve penalties for failing to update the emission class. However, applying may result in lower tolls – particularly beneficial for operators of modern, low-emission fleets.
