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.
