From zero to €300 a head: how much do Belgium's GAS fines really bring in?
A Het Nieuwsblad analysis of municipal accounts across Flanders finds that revenue from GAS fines — Belgium's municipal administrative penalties — swings from nothing to more than €300 per inhabitant, depending on the town.

- Het Nieuwsblad's analysis of Flemish municipal accounts finds GAS-fine revenue ranging from zero to more than €300 per inhabitant depending on the town.
- GAS fines are imposed directly by municipalities without a court; the maximum adult fine is €350 under the 2013 federal law, which also lowered the minimum age to 14.
- Leuven and Brugge collect steady, growing GAS income, while some municipalities raise almost nothing because they barely apply the system.
- Coastal and tourist-heavy towns such as Middelkerke rank high because parking and traffic penalties on visitors are counted against a small resident population.
GAS (gemeentelijke administratieve sancties) are municipal administrative sanctions: fines imposed directly by a Belgian municipality for minor nuisance — littering, vandalism, noise, wild urination, and increasingly low-level traffic and parking offences — without going through the criminal courts. They were introduced by the federal law of 13 May 1999 and expanded by the law of 24 June 2013, which lowered the minimum age to 14 and set the maximum adult fine at €350. Since 2021 many municipalities can also process certain traffic and limited-access-zone violations via GAS. Key named actors: the municipalities of Leuven, Brugge, Middelkerke, Halle and Leopoldsburg; the VVSG (Vereniging van Vlaamse Steden en Gemeenten), which represents Flemish local governments; and the Liga voor Mensenrechten, a leading GAS critic.
Background
Belgium created municipal administrative sanctions with the federal law of 13 May 1999 to relieve overloaded criminal courts of trivial nuisance cases. The system was significantly broadened by the law of 24 June 2013 — lowering the minimum age of liability to 14 and capping adult fines at €350 — a change that drew criticism from children's-rights and civil-liberties groups. A further shift came from around 2021, when municipalities were increasingly empowered to handle minor traffic and limited-access-zone offences through GAS, transforming what began as a litter-and-noise tool into a significant, and in some towns lucrative, enforcement channel.
What to do
The likelihood and size of a GAS fine for a minor offence in Belgium depend heavily on which municipality you are in; residents and visitors should be aware that parking, traffic and nuisance rules — and their prices — vary sharply between neighbouring towns.
Impact
Regional — The analysis centres on Flanders, comparing municipalities including Leuven (Vlaams-Brabant), Brugge (West-Vlaanderen), Middelkerke (coast), Halle (Vlaams-Brabant) and Leopoldsburg (Limburg). Coastal and city administrations that lean on traffic-related GAS collect far more per head than towns that barely apply the system, meaning residents and visitors face sharply uneven enforcement across neighbouring communities.
