Speed LimitsBelgium Motorway Speed 2026: 120 km/h, Section Control
Belgian motorways are limited to 120 km/h, widely enforced by average-speed section control. Outside towns the default is 70 km/h in Flanders and 90 in Wallonia; Brussels runs at 30.
Belgian motorways run at 120 km/h — but the number that catches visitors is the rural one, which is 70 in Flanders and 90 in Wallonia, and changes when you cross an internal border.
One country, two rural limits
Belgium devolved its road rules, and the most visible result is a split that exists nowhere else in Europe. Outside built-up areas, Flanders applies a default of 70 km/h; Wallonia applies 90 km/h. Brussels goes the other way entirely, with 30 km/h across most of the region.
There is no customs post between them. You cross from one regime into another on an ordinary road, and the only notice you get is the sign. A driver running from Antwerp to Namur passes through all three defaults in under two hours.
| Road Type | Cars | Trucks |
|---|---|---|
| Brussels region | 30 km/h | 30 km/h |
| Built-up area elsewhere | 50 km/h | 50 km/h |
| Outside built-up areas, Flanders | 70 km/h | 60 km/h |
| Outside built-up areas, Wallonia | 90 km/h | 60 km/h |
| Motorway | 120 km/h | 90 km/h |
Section Control Is the Enforcement Story
Belgium has rolled out average-speed section control faster than almost anywhere in Europe. Long stretches of motorway now measure your speed between two points rather than at one, which defeats the reflex of braking for a camera. The working tolerance is around 6 km/h.
Foreign plates are not a shelter. UK government travel advice confirms that “police use speed traps, cameras and unmarked vehicles” and that “speeding can result in an on-the-spot fine” (FCDO travel advice). Belgium participates in cross-border collection, and for a foreign-registered car the officer can require immediate payment.
The Low Emission Zones Are a Separate Fine
Brussels, Antwerp and Ghent all operate camera-enforced low emission zones, and the requirement is administrative rather than behavioural: you must pre-register your vehicle on the relevant city’s official website before entering. Drive in unregistered and the camera issues a penalty that has nothing to do with how you were driving.

The dual carriageway is not a motorway
A rural dual carriageway in Flanders is limited to 70 km/h, not 120. It looks like a motorway, it feels like one, and it is one of the most productive ticket sources in the country for visiting drivers.
Lit motorways, watched motorways
Belgium’s famously illuminated motorway network gives an impression of a relaxed, open road at night. The section control cameras do not switch off with the traffic.
Mandatory equipment turns a stop into an inspection
A warning triangle, reflective vest, first aid kit and fire extinguisher are all required. A speed check can easily become a full equipment check, each missing item carrying its own fine.
Phone use is expensive and actively enforced
UK government travel advice notes that “using a mobile phone while driving is illegal, unless you are using hands-free equipment”. Belgium treats it as a serious offence rather than a minor one, and the fines sit well above the level of a small speeding ticket.
Carry the documents
Licence, registration, insurance, roadworthiness certificate and passport are all expected to be in the car. Belgian police ask for them as a matter of routine.

120 km/h for cars, enforced heavily by average-speed section control rather than by single-point cameras.
Because the regions set them. Outside built-up areas Flanders uses a 70 km/h default and Wallonia 90 km/h, so the limit can change when you cross an internal regional boundary with no obvious signal beyond the sign itself.
30 km/h across most of the region, and it is strictly enforced. Brussels, Antwerp and Ghent also run camera-enforced low emission zones that fine non-compliant vehicles separately.
Yes if you drive into Brussels, Ghent or Antwerp. UK government travel advice states that vehicle pre-registration is required through each city's official website before you enter.
