How much speed-camera margin do I get in Belgium?
None — an 'allowed margin' doesn't exist; what exists is a technical measurement correction. Every clocked speed first gets a correction for measurement uncertainty: 6 km/h at speeds up to 100 km/h and 6 percent above. Clocked at 120 where 100 applies, the file says 112.8 — and the fine is computed on that. It is not a right to drive 6 too fast: the limit stays the limit, and the old extra 'tolerance margins' (quotas and thresholds that varied by prosecutor's office) are being phased out — cameras increasingly ticket from the first corrected km/h. Since 1 July 2026 a minor speeding offence in built-up areas costs €74 (previously €68), climbing per extra km/h. More than 20 km/h over in town or 30 elsewhere: prosecutor and possibly police court, with a driving ban on the table.
📋 The rules
- Technical correction: 6 km/h (≤100 km/h) or 6 % (>100 km/h) — not a licence to speed
- Fine computed on the corrected speed
- Minor urban offence: €74 (since 1/7/2026), + per extra km/h
- Extra prosecutor tolerance margins: being scrapped
- >20 km/h over (urban/zone 30) or >30 elsewhere: prosecutor/summons
🔓 Exceptions
- Average-speed checks: same correction on the averaged speed, no extra margin
- GAS administrative fines for limited speeding on 30/50 roads in Flemish municipalities: separate track
⚠️ Penalties & fines
From €74 (first degree, since 1/7/2026) rising per km/h; heavy speeding means a summons, fines in the thousands and a driving ban. Repeats within 3 years aggravate.

❓ Frequently asked
So I can drive 6 km/h over?
No — the 6 km/h/6 % corrects the device's measurement uncertainty; it's not a permitted margin, and betting on it eventually gets you flashed.
Clocked at 121 on the motorway — fined?
Measured 121 corrects to ±113.7 — under the 120 limit nothing punishable remains; measured 128 (corrected 120.3) does catch you.
What does 10 km/h over cost in town?
The first bracket costs €74 since 1 July 2026; every kilometre beyond 10 pushes the amount up.
Do prosecutor quotas still exist?
They historically varied by zone but are being systematically scrapped — counting on local leniency is outdated.
