Belgium Speeding Fines: Rates, Court Referral and the Opdecimes (2026)

A boete snelheid, or an amende excès de vitesse, is the most common traffic penalty issued in Belgium, and the amounts changed on 1 July 2026, the first increase since 2017. This page states the rates as they stand today: what the police collect at the roadside, when a roadside settlement is no longer on offer and you are summoned to court instead, and the separate opdecimes multiplier that applies once a court, rather than a police officer, sets the figure.

Speed enforcement in Belgium is federal, so every euro figure below applies the same way in Flanders, Wallonia and Brussels. What differs from one stretch of road to the next is only the posted limit and whether the road sits inside a zone that carries the higher per-km/h rate.

How a speeding fine is built

Belgium prices speeding in two steps. The first 10 km/h over the posted limit costs a flat 58 euro, whatever the road. Every km/h beyond that adds a further amount that depends on where you were driving: 12 euro per km/h inside a built-up area, a zone 30, a zone de rencontre (a shared low-speed zone) or a woonerf (a residential zone), and 7 euro per km/h everywhere else.

Two worked examples show how that adds up. Drive 20 km/h over the limit inside a zone 30: the first 10 km/h costs 58 euro, and the remaining 10 km/h costs 10 times 12 euro, or 120 euro, for a base total of 178 euro. Drive the same 20 km/h over on a road outside those zones, say a motorway: the first 10 km/h still costs 58 euro, but the remaining 10 km/h costs 10 times 7 euro, or 70 euro, for a base total of 128 euro. In both cases, the fixed administrative fee described below is then added on top, and neither total is what a court would impose if the matter were instead referred there.

Four zone types share the higher rate, not just "built-up"

A common misunderstanding is that the higher, 12-euro-per-km/h rate applies only inside a built-up area in the everyday sense. It in fact applies across four distinct zone types: the bebouwde kom, the agglomeration in the ordinary sense; a zone 30; a zone de rencontre, a shared-space zone with a low posted speed; and a woonerf, a residential zone in the stricter sense. Outside all four, the lower 7-euro-per-km/h rate applies instead.

The administrative fee: a mechanism, not a figure stated here

On top of the per-km/h calculation, a fixed administrative fee is added to every speeding fine. That fee is indexed every January, so it changes annually, and the current euro amount is not published on a source this page treats as verified for citation. mobilit.belgium.be confirms the fee exists and that it is indexed each year; for the actual current amount, check justonweb.be, the federal government's own portal for looking up and paying road fines, rather than relying on a figure quoted elsewhere.

When perception immediate is no longer on offer

Immediate roadside settlement, perception immediate or onmiddellijke inning, is not always available. It is excluded, and you are instead summoned to the politierechtbank, the tribunal de police, once you exceed the limit by more than 40 km/h, or by more than 30 km/h inside a built-up area, a zone 30, a zone de rencontre or a residential zone. It is also excluded once the total would exceed the caps described below, for a combined third-degree infraction, and for any fourth-degree infraction committed by a Belgian resident. A non-resident committing the same fourth-degree infraction can, unusually, still be offered immediate perception.

The technical correction is not the same as the tolerance

Two separate adjustments get confused constantly, and they are not the same thing. The technical correction is a fixed, statutory margin applied to every measured speed before an offence speed is even set: minus 6 km/h for a measured speed under 100 km/h, and minus 6 percent for a measured speed at or above 100 km/h. It applies automatically, every time, to every measurement, regardless of where the measurement was taken.

The discretionary tolerance, the marge de tolerance or tolerantiemarge, is a different thing entirely: a prosecutorial practice, not a statutory figure, and it has been phased out on highways and certain other roads rather than abolished everywhere. Do not assume it still applies on every road just because the technical correction always does, and do not assume it has disappeared everywhere just because it has been withdrawn on highways.

Caps on the roadside amount, and the non-resident consignment

Immediate perception itself is capped. It is excluded once the total would exceed 382 euro for someone with a fixed address in Belgium, or 953 euro for someone with no fixed Belgian address, in either case sending the matter to court instead. A non-resident who is referred to court must additionally consign 1,386 euro pending trial.

Roadside fine versus court fine: where the opdecimes comes in

Every figure above is a perception immediate, an amount a police officer can collect at the roadside or that follows by payment order. A court sets a different, larger figure. When a case is referred to the politierechtbank, the tribunal de police, whether because of the thresholds above or for any other reason, the fine imposed is the underlying statutory fine multiplied by the opdecimes, a multiplier that rose from eight times to ten times on 1 February 2026. The roadside perception amount and a court-imposed fine answer two different questions, and treating one as if it were the other will make either figure look wrong.

Frequently Asked Questions

How much is a Belgian speeding fine for going 10 km/h over the limit?

Since the 1 July 2026 increase, the first 10 km/h over the posted limit costs a flat 58 euro, the same figure everywhere in Belgium, plus the fixed administrative fee described on this page.

Does the per-km/h rate change depending on where I was speeding?

Yes. Beyond the first 10 km/h, each additional km/h costs 12 euro inside a built-up area, a zone 30, a zone de rencontre or a woonerf, and 7 euro per km/h everywhere else.

At what point do I get summoned to court instead of paying at the roadside?

Immediate perception is excluded, and you are summoned to the politierechtbank, the tribunal de police, once you exceed the limit by more than 40 km/h, or by more than 30 km/h inside a built-up area, a zone 30, a zone de rencontre or a residential zone.

Is the technical correction the same thing as the tolerance margin?

No. The technical correction, minus 6 km/h under 100 km/h and minus 6 percent at or above, is a fixed statutory margin applied to every measurement. The discretionary tolerance is a separate prosecutorial practice, being phased out on highways and certain other roads, not a fixed figure and not withdrawn nationwide.

How much is the fixed administrative fee added to a speeding fine?

Its existence and its annual indexation each January are confirmed on mobilit.belgium.be, but this page does not state a current euro figure because that amount is not published on a source treated as verified here. Check justonweb.be for the amount currently in force.

What happens if the total fine would be over the cap?

Immediate perception is excluded once the total would exceed 382 euro for someone with a fixed address in Belgium, or 953 euro for someone without one, and the matter goes to court instead. A non-resident referred to court must also consign 1,386 euro pending trial.

Why does a court-imposed speeding fine look so different from the roadside amount?

Because the two are calculated differently. The roadside figure is the perception immediate described on this page. A court-imposed fine is instead the underlying statutory fine, set by the Wegverkeerswet, multiplied by the opdecimes, which rose from eight times to ten times on 1 February 2026, so the two numbers are never meant to match.
