Belgian Road Toll Faces EU Ban

Belgium is getting ready to charge every car using its roads through a digital vignette, with the scheme due to begin in May 2027. There is nothing inherently unlawful about that. EU rules allow member states to charge for road use under the Eurovignette directives, the bloc’s framework for road pricing, provided the charge does not discriminate by nationality.

The difficulty is what Belgium appears to be preparing around the charge. If Belgian drivers pay the vignette but then recover the cost through lower domestic car taxes, while Dutch, French and German drivers pay the full amount, the toll stops being equal in any meaningful sense.

The Precedent Germany Created

The Court of Justice of the European Union has already dealt with this exact structure. In 2019, it struck down Germany’s planned passenger-car toll in Austria v Germany (Case C-591/17). Berlin had designed a toll that, on paper, applied to everyone. But it also reduced motor-vehicle taxes for German-registered cars, meaning German drivers were made whole while foreign drivers carried the real cost.

The Court treated that as indirect discrimination under Article 18 TFEU, the treaty rule banning nationality-based discrimination inside the single market. The lesson was plain enough: a toll can be neutral in its wording and still unlawful if its economic effect falls mainly on non-residents. The judges looked at the whole package, not just the toll notice.

Belgian reporting suggests a similar design may now be emerging. BRUZZ says the vignette is tied to a wider reform of traffic taxation. Belgian German-language outlet BRF has reported that costs for Belgian residents could be "offset or settled through the traffic tax", the annual vehicle registration charge paid by car owners in Belgium. If that happens, Belgium would be walking close to the German line.

The mechanics matter because Belgium is not a simple centralised state. Vehicle registration taxes are controlled by the three regions, Flanders, Wallonia and Brussels-Capital, rather than by the federal government. That is not a constitutional footnote. In the German case, the Court examined the net burden created by the toll-and-tax system as a whole. If even one Belgian region cancels out the vignette for residents through its own tax relief, the scheme could face a discrimination challenge.

Dutch Drivers at the Border

The sharpest response has come from the Netherlands. Dutch infrastructure minister Vincent Karremans has called the plan "disappointing" and has pressed his Flemish counterpart for easier treatment of regular border crossers.

This is not a theoretical complaint. People in Noord-Brabant, Zeeland and Limburg cross into Belgium for work, shopping and family visits as part of ordinary life. Some do it several times a week. A national vignette would turn that routine cross-border traffic into a recurring charge. For Irish readers, the sensitivity is familiar enough: once daily life runs across a border, small administrative changes can carry a political weight far beyond the fee itself.

The Dutch objections have not yet become legal action. According to ANP-BELGA reporting, Belgium’s proposal is expected to go to the European Commission in August. If the Commission believes the design breaches EU law, it can open an infringement procedure, the formal route by which Brussels takes a member state to court. The Netherlands could also bring a state-to-state case, though it would first have to go through the Commission. It has not done so.

For now, the resistance is mainly Dutch. Germany’s ADAC, the country’s largest motoring association, still describes Belgian motorways as essentially toll-free for passenger cars, which gives a sense of how visible the change would be. Berlin, however, has not objected, and there is no sign yet of a wider coalition of neighbouring states forming against the plan.

The Design Will Decide

Belgium has a defensible argument for road charging. Foreign cars use Belgian roads, and asking users to contribute to infrastructure costs is not, in itself, an EU problem. The legal issue is narrower and more dangerous for Brussels: whether Belgian drivers end up paying less than the advertised price while foreign drivers pay the full fare.

That answer will depend on how the regions handle any traffic-tax offset. The final legal text has not been published. The European Commission is expected to review the proposal in August, before the vignette takes effect.

If Belgium creates a genuine equal-cost toll, it should survive. If it recreates Germany’s old model with a Belgian regional twist, the Court has already written the ending.
