Driving without a number plate in Belgium: fine and consequences

Driving without a number plate in Belgium is a second-degree traffic offence. That applies to an unregistered vehicle, to a missing front plate and to a plate that is illegible or covered. For offences committed from 1 September 2026, you face a court fine of 200 to 5.000 euros; at the roadside, the police often offer an immediate payment (onmiddellijke inning / perception immédiate) of 128 euros.

If you are also driving without insurance, the matter becomes far more serious. Below we explain what is compulsory and how best to respond.

The registration requirement: no driving without a registration plate

In the legislation, the number plate is called a registration plate (kentekenplaat / marque d’immatriculation). The rules are set out in the Royal Decree of 20 July 2001 on the registration of vehicles. Article 2 is clear: a vehicle may only be put into traffic if it is registered. There are only a few exceptions, such as vehicles of the Belgian Defence forces.

If you live in Belgium, a vehicle you use here must be registered in Belgium, even if it is already registered abroad (art. 3). A person living abroad must have the vehicle registered in an EU Member State or a treaty state and carry the plates required by that country (art. 4).

In Belgium, the plate follows the person who registers the vehicle, not the vehicle itself. When registering a new vehicle, you can ask to reuse a plate already in your name (art. 22, § 2). If you stop using a vehicle, you must return the plate within fifteen days (art. 35).

Rear plate and front plate: what is compulsory?

The official registration plate you receive on registration is fitted at the rear, in the space the vehicle provides for it. The decree refers to the European rules on rear registration plates for this purpose (art. 29).

At the front there is no second official plate, but a reproduction: the front plate. For cars, vans, lorries and buses, this reproduction is compulsory. It must be fixed in the middle or on the left-hand side of the front, in a roughly vertical plane, with its upper edge no more than 2 metres above the ground (art. 30). Buy a reproduction that meets the specifications laid down by the minister (art. 21).

For motorcycles and mopeds, article 30 does not provide for a reproduction at the front; the rear plate is sufficient. A reproduction is, however, compulsory on a bicycle carrier mounted at the rear or on the tow bar and, in certain cases, on a trailer.

Illegible, hidden or altered plate

The plate and its reproduction must be firmly attached and remain visible at all times. In daylight and clear weather, they must be legible from at least 40 metres. For small plates measuring 210 x 140 mm, the distance is 30 metres, and for motorcycles 20 metres (art. 29).

Article 31 prohibits any interference with the plate, the reproduction or their immediate surroundings that could cause confusion about what is shown. Drilling additional holes is also prohibited. The plate may never be covered, not even with transparent material, so tinted films and covers are ruled out. A plate caked in mud or snow is not legible either.

Unregistered vehicle or another vehicle’s plate

The Road Traffic Act (Wegverkeerswet / loi relative à la police de la circulation routière) classifies registration-related conduct that allows a person to evade prosecution as a second-degree offence (art. 29, § 1, third paragraph, Road Traffic Act). The Royal Decree of 30 September 2005 (art. 2) designates, among others:

• No registration. Putting into traffic a vehicle that is not registered, for example a car you have just bought or a vehicle whose plate has been returned (art. 2 Royal Decree of 20 July 2001).
• Wrong plate. A vehicle not carrying the plate assigned on its registration, such as the plate from your previous car or from another vehicle.
• Foreign registration. Driving, as a Belgian resident, a vehicle registered only abroad, outside the statutory exceptions (art. 3).
• Temporary registration. Failing to comply with the conditions of a temporary registration (art. 5).
• Altered plate. Driving with a plate whose number, embossed seal or the plate itself has been altered.
• Fitting and reproduction. Failing to comply with the rules on fitting and reproduction: missing front plate, illegible or covered plate (art. 29 to 31).

Where a stolen or counterfeit plate is involved, offences under the ordinary criminal law may also come into play.

The link with compulsory insurance

A vehicle without valid registration is often uninsured as well, for example where the plate has been returned and the policy cancelled. A motor vehicle may only use the public road if civil liability is covered (art. 2, § 1 of the Act of 21 November 1989, the Motor Insurance Act or WAM-wet). Driving without that insurance is a separate and much more serious offence (art. 22 of the Motor Insurance Act), for which the court may also impose a driving disqualification (verval van het recht tot sturen).

In the event of an accident, you also risk being held personally liable for the damage. Read more in our article driving without insurance: what are the risks? and on our page about assistance when driving without insurance.

Penalties for offences committed from 1 September 2026

Since 1 September 2026, the Road Traffic Act uses the penalty levels (strafniveaus) of the new Criminal Code. A second-degree offence is punishable by a level 1 penalty, with a fine that the statute sets at 160 to 4.000 euros (art. 29, § 1, third paragraph, Road Traffic Act). With the surcharge multiplier (opdeciemen, x 1,25), you actually pay 200 to 5.000 euros. Level 1 means no prison sentence.

For offences committed before 1 September 2026, the former penalties and surcharges still apply. If the new law is more lenient for you, you benefit from it (art. 2 Criminal Code). You will find more information in our article on the new Criminal Code and traffic offences. Prosecution becomes time-barred after three years (art. 68 Road Traffic Act).

Immediate payment, settlement and payment order

When an offence is recorded, the police may offer an immediate payment, provided that nobody suffered damage (art. 65 Road Traffic Act). For a second-degree offence it has amounted to 128 euros since 1 July 2026. If you committed, at the same time, an offence for which no immediate payment is possible, that option lapses for the whole.

If you do not pay, an offer of settlement (minnelijke schikking / transaction) usually follows (art. 216bis Code of Criminal Procedure). If that also remains unpaid, the public prosecutor may issue a payment order (bevel tot betalen / ordre de paiement): the sum increased by 35 %, payable within 30 days. Within the same 30 days, you can lodge an appeal with the police court (politierechtbank / tribunal de police) (art. 65/1 Road Traffic Act).

Payment in principle ends the prosecution, unless the public prosecutor’s office announces within one month that it will prosecute nonetheless.

What should you do?

1. Check your vehicle. Is the rear plate firmly attached, and are the reproductions at the front and on the bicycle carrier present, legible and uncovered?
2. Do not drive before registration. Only drive away a car you have bought once it is registered in your name and insured.
3. Gather evidence. Take photos of the plate and reproduction straight away and keep your registration certificate and proof of insurance.
4. Read the payment proposal carefully. Which facts, which article and which deadline?
5. Do not pay blindly. If you believe the finding is wrong, have the file reviewed before the deadline expires.
6. Check the insurance. Was the vehicle insured at the time of the facts? If not, seek legal advice immediately.
7. Received a summons? The case will then go before the police court. First read our article on a summons to the police court.
