Kilometer charge: what will change on January 1st

By: stephanie

Brussels, December 7, 2023 – From Monday January 1, 2024, the following elements will be changed in the kilometer charging system:

In Flanders, the tariff for 686 km of roads will go from zero to a normal tariff. A preferential rate of zero cents/km will be granted to zero-emission vehicles (ZEV) across the entire Flemish road network. However, the OBU remains mandatory for ZEVs. In the Brussels-Capital Region and Wallonia (Sofico), ZEVs will still be classified in the EURO VI emission category.

In Wallonia (Sofico structuring network), the kilometer charge rates will be indexed. In Flanders and the Brussels-Capital Region, indexation will take place on July 1.

The use of an OBU of the TriBoxAir type from the service provider Eurotoll will no longer be permitted on Belgian roads as from 01/01/2024. The service provider Eurotoll has already informed its affected customers. Customers of this service provider who have not yet received a message or who have not yet replaced their TriBoxAir are invited to contact Eurotoll.

The software of activated OBUs (On Board Units) of the six service providers accredited to operate mileage collection in Belgium will be automatically updated in order to reflect the new rates and network coming into force from January 1. The six service providers concerned are Axxès, Satellic, Telepass, Toll4Europe, TotalEnergies Marketing Services and W.A.G. Payment Solutions.

An OBU is a device in the truck cabin that records the number of kilometers driven on paying toll roads. Trucks and semi-trailer towing vehicles registered in Belgium or abroad must always have the OBU switched on when driven on public roads in the three regions.

The amount charged per kilometer on toll roads depends on three factors: the region where the road is located, the GVW and the Euro emission standard of the vehicle. The kilometer charge applies to three GVW categories (more than 3.5 tons to 12 tons, more than 12 tons to 32 tons, and more than 32 tons) and seven Euro standards (from the most polluting Euro 0 standard to the most environmentally friendly Euro 6 standard). The higher the Euro standard of the vehicle and the lower its GVW, the more advantageous the tariff per kilometer driven.

On 1 January, the new tariffs will be available for consultation on the download page of the Viapass website. You can already consult the tariffs that will apply then via the site’s “news” page.


  • The preferential rate for ZEVs will only apply in Flanders. In Brussels and Wallonia (Sofico), ZEVs will still be part of the EURO VI category.
  • ZEVs must always be equipped with an OBU, even on Flemish roads.

The zero-fare routes that will change to normal fare in Flanders are shown on the map below.

  • Dark purple roads constitute the current non-zero tariff road network;
  • Light purple routes are routes that will go from zero fare to normal fare on 01/01/2024.
