Belgium Driving Laws: Traffic Fines, GAS Sanctions and Perception Immediate

Belgian traffic law runs on two separate tracks that are easy to confuse. Moving violations, from speeding to running a red light, are federal offences prosecuted under one law, in one system of courts, the same way everywhere in the country. Stopping and parking violations, by contrast, can be handled locally, by the municipality, under an entirely different administrative system. This section, part of the wider Belgian legal guide, covers both, plus the roadside settlement mechanism that resolves most minor traffic offences before either system reaches a courtroom.

Whether you are reading this because of a speeding ticket, a parking fine, or simply to understand how Belgian traffic enforcement works, the two spoke pages below go into the figures and procedure in detail. This page orients you first.

Two separate systems, one federal frame

The starting distinction is jurisdictional, not just procedural. Moving violations, meaning anything to do with how a vehicle is driven: its speed, a red light, alcohol, lane discipline, are governed by the Wegverkeerswet, the loi relative à la police de la circulation routière, a federal statute, and, when a case is serious enough to reach a courtroom, they are heard by the politierechtbank, the tribunal de police, the specialised traffic court found across the country. A municipality has no power to fine a moving violation itself, however strongly a local council might feel about a particular stretch of road.

Stopping and parking, by contrast, sits on a separate track. A gemeentelijke administratieve sanctie, a sanction administrative communale (GAS / SAC), lets a municipality issue its own administrative fine for a violation, but only for the narrow category of offences a federal decree actually lists, principally stopping and parking violations and certain sign infringements. The GAS / SAC municipal fines page covers exactly where that boundary sits.

Perception immediate: how most tickets actually get resolved

Most Belgian traffic offences never reach a courtroom because the perception immediate, onmiddellijke inning, system settles them first. A police officer, or a payment order sent afterward, offers a fixed amount that closes the matter once paid, avoiding both a court date and the need for the case to be tried. The speeding fines page sets out the current, post 1 July 2026, figures for speed specifically, including the point at which this option disappears and a court summons follows instead.

Four degrees of severity

Belgian traffic law grades offences into four degrees, and the degree drives both the size of any fine and whether roadside settlement is even on offer. A first-degree offence is treated as comparatively minor; a fourth-degree offence, at the other end, can exclude immediate perception altogether for a Belgian resident, a rule the speeding fines page explains in more depth for that specific offence.

Why the same statute can quote two different euro figures

A recurring source of confusion is that a Belgian traffic statute can state one euro figure while a court, or a roadside fine, applies a different one. Two mechanisms explain most of that gap. First, the opdecimes: a multiplier applied to a bare statutory fine once a court imposes it, and that multiplier rose from eight times to ten times on 1 February 2026, so an article figure quoted from before that date understates the real number. Second, the 1 July 2026 increase: every perception immediate amount, the figures collected at the roadside, rose 10 percent that day, the first change since 2017, so a pre-2026 figure circulating anywhere, in an old article or an old fine notice, is no longer current either.

The two spokes

Speeding fines sets out the current per-km/h rates, the built-up-zone premium, the technical correction, the caps on immediate perception, and the opdecimes distinction described above, in full.

GAS / SAC municipal fines sets out the municipal fine ceilings, who imposes a GAS fine and who hears an appeal, and exactly how narrow the traffic slice of the GAS system actually is.

Frequently Asked Questions

Is Belgian traffic law the same in every Region?

Yes, for the offences and fines described in this section. Moving-violation law and its enforcement are federal, so the rules are identical in Flanders, Wallonia and Brussels. What differs locally is only the posted speed limit or a municipality's own parking regulation.

What is the difference between a federal traffic fine and a GAS fine?

A federal traffic fine covers moving violations, from speeding to a red light, prosecuted under the Wegverkeerswet before the politierechtbank, the tribunal de police. A GAS fine is a municipal administrative fine, and in traffic it is limited to stopping and parking violations and certain sign infringements; a municipality cannot use it for a moving violation.

What is perception immediate, onmiddellijke inning?

It is the roadside or payment-order settlement that resolves most minor traffic offences without a court appearance. It is not available above certain thresholds, which vary by offence; the speeding fines page sets out the thresholds for speed specifically.

Why did Belgian traffic fines change on 1 July 2026?

Perception immediate amounts across the board rose 10 percent that day, the first such increase since 2017. Any figure quoted from before that date is now out of date.

What are the four degrees of traffic offence?

Belgian traffic law sorts offences into four degrees of severity, with the degree driving both the size of a fine and whether immediate roadside settlement is available at all. The highest degree can exclude roadside settlement altogether for a Belgian resident.

Why do court-imposed traffic fines look bigger than the figure printed in the statute?

Because a court applies the opdecimes, a multiplier on top of the bare statutory figure, and that multiplier rose from eight times to ten times on 1 February 2026.
