The year 2024 will bring changes to toll systems and increases in toll rates in many EU countries.

By March 2024, all EU member states must transpose the Eurovignette Directive (2022/362) into national law , which provides for a number of changes to road toll systems.

Among other things, it aims to reduce greenhouse gas emissions from road transport. The main change it implies is variable tolls, depending on the CO2 emissions of the vehicle.
The changes in tolls will certainly translate into increased costs for international transport and our rates.

Germany was the first country to introduce the relevant changes on December 1, 2023.

Other member states have already announced changes for 2024, let us introduce some of the changes in particular countries.

Belgium

At the turn of the year, the Belgian toll rates increased, as it does every year. The average adjustment of the index for January 2024 is +4.08 percent.
A significant change to the Belgian toll system is that as of January 1, 2024 the toll extends to an additional 686 kilometers of roads in Flanders. This represents an expansion of the toll road network by 30 percent.

Germany
Although the toll rates were raised significantly on December 1, 2023, the changes to the German toll system are not yet complete. From January 1, 2024, CNG and LNG trucks will be subject to tolls. Only electric trucks and hydrogen-powered vehicles will be exempt from tolls in Germany (until the end of 2025).
In addition, the toll in Germany will be expanded to include trucks over 3.5 t from July 1, 2024 (currently vehicles over 7.5 t are subject to toll). Moreover, the CO2 rate will increase from 30 euros per ton to 45 euros from January 1st.

Hungary
From January 1, 2024, road tolls in Hungary will also increase due to requirements by the EU Eurovignette Directive.
Calculating the external cost fee is complex, therefore the Hungarian Toll Directorate has designed a toll calculator, with which the exact amount of the toll can be estimated after entering the relevant data.
The toll calculator, which is available in English and Hungarian, can be accessed directly on the toll system operator’s website

Austria
The Austrian Motorway Directorate (ASFINAG) put a special emissions class calculator, which hauliers can use to check which class their vehicle falls into. The class then determines the amount of the CO2 tax.
