Brussels LEZ 2026: you may already be driving… towards a €350 fine

Introduction

You have a Euro 5 diesel or an older petrol car and you keep driving in Brussels with no apparent problem? You haven't received any fine and everything seems normal? That is exactly what makes the situation misleading.

Since 1 January 2026, certain vehicles have officially been banned from the Brussels low emission zone. Yet many drivers keep driving without being penalised straight away. This creates a sense of security… that does not reflect reality.

At Garage Privé, we see a lot of confusion around this subject. Many drivers think that as long as they receive nothing, they risk nothing. This reasoning is understandable, but it is wrong.

Why you can be in breach without knowing it

The way the LEZ system works largely explains this confusion. When an offence is recorded, it does not lead directly to a fine. First, a warning is sent. Only after a three-month period, if the situation has not been put right, can a fine of €350 be imposed.

In other words, there is a gap between the moment you are in breach and the moment you are actually penalised. During that time, you can keep driving thinking everything is in order, when it is not.

On top of that, in 2026 the strict enforcement of fines was temporarily postponed for political reasons. This further reinforces the impression that the rules are not really being applied, when they very much are.

A timeline that traps drivers

This time lag is exactly what causes the problem. A driver can drive for several weeks, or even several months, without receiving a penalty. They may then conclude that the rules are lenient or rarely enforced.

In reality, it is simply a delayed effect. Offences are indeed recorded, but the consequences come later. With the recent adjustments, fines should be applied more concretely from June 2026.

This means the current situation is temporary. Receiving nothing today is absolutely no guarantee that there will be no penalty tomorrow.

A very common error of reasoning

Many drivers unconsciously follow the same reasoning: they rely on their immediate experience to judge the real risk. Since they see no direct consequence, they conclude there is no danger.

This is a classic mistake. From the driver's point of view, the LEZ system does not work in real time. It works with a delay, which distorts the perception of risk.

So the danger is not the immediate fine, but building up offences without realising it.

The real impact on the value of your car

Beyond the fines, there is another often underestimated factor: the value of your vehicle.

A vehicle affected by LEZ restrictions gradually becomes harder to sell. Buyers are increasingly well informed and anticipate the bans. They know they will face restrictions in the short term, or may even no longer be able to drive freely.

This automatically leads to lower demand, pressure in negotiations and, in some cases, an outright refusal to buy.

Thinking that the value of your car stays stable because you can still drive it today is therefore questionable. The regulations directly influence the market, even before the penalties are fully applied.

Wait or anticipate: a real strategic choice

Faced with this situation, two clear patterns of behaviour are emerging.

Some drivers choose to wait. They keep using their vehicle as long as that seems possible, without thinking ahead about the medium-term consequences. They often end up selling in a hurry, when the constraints become too great, at a reduced price.

Others prefer to anticipate. They take market trends into account and decide to act before the situation gets worse. This approach generally lets them sell on better terms and without pressure.
