Belgian limits depend on the region. Built-up areas are 30 km/h in Brussels and 50 km/h in Flanders and Wallonia. Ordinary roads outside them are 70 km/h in Flanders and Brussels and 90 km/h in Wallonia, and motorways are 120 km/h. Belgium uses fixed cameras and a large network of average-speed sections.
| Road type | Brussels | Flanders | Wallonia |
|---|---|---|---|
| Built-up areas | 30 km/h | 50 km/h | 50 km/h |
| Ordinary roads outside built-up areas | 70 km/h | 70 km/h | 90 km/h |
| Motorways | 120 km/h, usually signed lower | 120 km/h | 120 km/h |
What are the speed limits in Belgium?
Article 11 of the Belgian Highway Code sets a separate general limit for each of the three regions, and a sign always replaces it.
- Brussels-Capital Region: 30 km/h in built-up areas and 70 km/h on ordinary roads outside them. The 120 km/h motorway limit applies almost nowhere in the region, because signs set a lower limit.
- Flanders: 50 km/h in built-up areas and 70 km/h outside them. Some roads carry a sign allowing 90 km/h.
- Wallonia: 50 km/h in built-up areas and 90 km/h outside them, with 30 km/h on stretches for pedestrians and cyclists marked by signs D9 or D10.
- Motorways and dual carriageways: 120 km/h for cars on motorways and on roads with at least two lanes each way and physically separated directions.
Because the general limit changes with the region, read each sign on a trip across the country. A revised Highway Code is due to take effect on 1 June 2027, according to the Wegcode site, so check again after that date.
What kinds of speed cameras does Belgium use?
Belgium uses automatic fixed and average-speed devices, and Article 62 of the Road Traffic Act gives their recorded evidence legal weight.
- Average-speed sections (trajectcontrole): Flanders describes these as number-plate cameras that measure average speed over a longer distance, with results passed to the federal police. VRT reported 281 working sections across Belgium in May 2023, citing a parliamentary answer from the Interior Minister.
- Wallonia: RTBF reported 16 approved average-speed sections on Walloon motorways in March 2026, citing Vias. RTBF reported in August 2025 that the Walloon programme planned 150 devices for that year: 100 fixed radars, 40 average-speed sections and 10 red-light cameras.
- Road safety results: Flanders cites a Hasselt University study that found fewer speeders and fewer crashes on motorway sections with trajectcontrole.
We found no current count for the whole country, so this guide does not give one.
Are speed camera apps legal in Belgium?
We found no specific rule on location-based warning apps in Belgium, so check locally if you need certainty. Article 62bis of the Road Traffic Act bans intentionally carrying any equipment or other means that hinders or prevents the recording of offences, or that detects automatic enforcement devices, and it does not name apps. ADAC’s country table (May 2025) lists location warnings in navigation systems as permitted in Belgium. Article 8.4 of the Highway Code separately bans using, holding or handling a mobile device with a screen while moving, unless it is fixed in a holder made for that purpose (checked on 30 October 2026).
What should visiting drivers know about Belgium?
- Speeds are in km/h, and the general limit depends on where you are, not on where your car is registered.
- A road with a general limit of 90 km/h in Wallonia drops to 70 km/h at the line into Flanders, unless a sign says otherwise.
- Next door, the Netherlands has limits that change by the hour, and Germany bars drivers from using warning functions.
