Belgium's three regions announced on Friday that they would introduce a road tax next year that foreign drivers transiting the country would also have to pay.
The country does not currently charge drivers to use its highways and the issue of introducing some form of payment has been debated for years.
"Everyone who uses our roads must contribute fairly to their maintenance," said the transport minister for the southern Wallonia region, François Desquesnes.
Starting on 1 May 2027 drivers will need to register their vehicle and pay the road tax, with day passes available for drivers driving across the country.
An annual pass for a zero-emission car will cost €90 and up to €125 for higher polluting vehicles.
Road cameras that catch cars that haven't paid for a pass will incur a fine of €70.
In Belgium, the individual regions are responsible for maintaining roads and motorways.
Currently, drivers can use almost all highways toll-free but the possibility of an introducing a charge has been under discussion for several years.
The revenue would be used for the operation and maintenance of the road network.
The proposed toll still needs final approval from the regions and European authorities.
According to the chairman of the liberal-conservative MR party, the government intends to offset the new toll by lowering other taxes for Belgians.
