Traffic rules
Brussels
1. Brussels
Brussels is Belgium’s capital region and consists of 19 municipalities at the centre of the country, completely surrounded by Flanders. Traffic drives on the right. Driving is predominantly urban, with busy junctions, trams, buses, cyclists, pedestrians and extensive one-way and restricted-access streets. Since 2021, Brussels has operated as a City 30: 30 km/h is the general speed limit throughout the region, while selected major roads are specifically signed at 50 or 70 km/h and residential or meeting zones can be limited to 20 km/h.
The Brussels-Capital Region also operates a region-wide low-emission zone covering all 19 municipalities, apart from the R0 Ring and certain access roads to transit car parks. Its emission requirements became stricter again on 1 January 2026. Written road information is commonly provided in French and Dutch, the region’s two official languages. Passenger cars do not need a road vignette, although qualifying goods vehicles are subject to Belgium’s kilometre-charge system.

What alcohol limits apply to drivers in Brussels?
For most drivers, the Belgian offence thresholds start at 0.5 g/l in blood or 0.22 mg/l in breath. For the professional-driver categories specified in Article 34, the lower thresholds start at 0.2 g/l in blood or 0.09 mg/l in breath. These are corresponding legal thresholds, not safe drinking targets. Being young or inexperienced does not by itself create a lower alcohol threshold, although novice-driver penalties can differ.

What speed limits apply to passenger cars in Brussels?
City 30: The general speed limit in built-up areas in the Brussels-Capital Region is 30 km/h. This City 30 rule applies unless a traffic sign indicates another limit.
Signed exceptions: Certain major roads are specifically signed at 50 km/h or 70 km/h. These are exceptions to the regional 30 km/h default, so drivers must follow the posted signs.
Residential areas: In a residential area indicated by the appropriate traffic signs, the maximum speed is 20 km/h.

Seat belts: The driver and passengers must wear a seat belt on seats equipped with one, subject to limited legal exemptions.

Can you use a mobile phone while driving in Brussels?
A driver must not use, hold or manipulate a mobile electronic device with a screen unless it is secured to the vehicle in an appropriate holder. The legal exception for a vehicle that is standing or parked does not cover waiting at a red light or in a traffic queue. A holder does not remove the duty to drive safely.

Who has priority at an uncontrolled intersection in Brussels?
The general Belgian rule is priority from the right. A driver must give way to a vehicle approaching from the right unless traffic signs, signals or another statutory exception establish a different priority.
How does zipper merging work in Brussels?
When traffic is moving very slowly and a lane ends or is blocked, drivers in that lane must merge only immediately before the narrowing. Drivers in the continuing lane must let vehicles merge alternately, one at a time. If lanes end on both sides of the continuing lane, allow a vehicle from the right first and then one from the left.

Do drivers have to form an emergency corridor in Brussels?
Yes. As soon as a queue begins to form on a road with at least two lanes in the same direction, drivers must create a rescue corridor for priority vehicles. The rule also applies on urban roads.

What safety equipment must a car carry in Brussels?
An ordinary Belgian-registered car must carry an approved warning triangle, fire extinguisher, first-aid kit and reflective safety vest. Keep the vest accessible and wear it when the breakdown rules require it, particularly on motorways and expressways. Requirements for foreign-registered vehicles can differ.

What should drivers check before entering a low-emission zone in Brussels?
Coverage: The Brussels Low Emission Zone (LEZ) covers all 19 municipalities of the Brussels-Capital Region and applies continuously. Vehicle access depends mainly on vehicle category, fuel type and Euro emission standard.
Boundaries: The R0 Ring is outside the Brussels LEZ. Certain roads providing access to designated transit car parks are also excluded, allowing some drivers to reach a Park & Ride without entering the LEZ itself.
Foreign vehicles: Most vehicles registered abroad must be registered with the Brussels LEZ system even if they satisfy the emission standard. Vehicles registered in the Netherlands are currently exempt from this separate registration requirement because their data can be obtained automatically.

Can a visitor use a driving licence issued in another EU country in Brussels?
Yes. A valid, full EU driving licence is recognised for the vehicle categories it covers. You must meet the applicable minimum age. A learner licence or a temporary replacement certificate does not have the same automatic recognition.
Are motorcycle helmets compulsory in Brussels?
Yes. On an ordinary, open motorcycle, both the rider and passenger must wear a protective helmet. Use a helmet that meets the applicable approval requirements and fasten it correctly. Check the specific rules before relying on an exemption for an enclosed or specially equipped vehicle.
