A traffic summons arrived: what happens next
Fines, the immediate settlement, the hearing, and the one thing worth deciding before the deadline on the letter.

Most traffic matters in Belgium never reach a courtroom. They are dealt with by an immediate settlement — a proposed sum, sent by post, which closes the file when it is paid. Understanding what that payment means is the part that catches people out.
Paying is a decision, not a formality
Paying an immediate settlement normally extinguishes the prosecution, which is usually what people want. It also ends the possibility of contesting the facts, and it does not undo everything that follows from them: an insurer may still take the offence into account, and for a few regulated professions an entry on a record matters.
Where a driving ban is at stake, the settlement route is generally not the one offered at all — you are summoned before the police court instead. A summons and a payment slip are two different letters asking for two different decisions, so the first useful step is to be certain which of the two you are holding, before the date printed on it.
If you contest
Not paying does not make the file disappear. The public prosecutor may summon you before the police court, which is where road traffic matters are heard. There you can be assisted by a lawyer, present your version and produce evidence — a calibration certificate, photographs, a witness, medical circumstances.
Speed measurements, alcohol readings and technical devices all have rules about how they must be operated and documented, and those rules are sometimes the substance of a defence. That is a file question, not something anybody can promise in advance.
Driving bans and repeat offences
The stakes change when a ban is on the table, and again when the record shows earlier offences. A ban has consequences for work and family that a court can take into account, but only if they are put before it, with documents. This is where a lawyer earns the fee most reliably, and where turning up alone is the most expensive choice.
Cost, and who might pay it
Many motor and household policies include legal-expenses cover for road traffic proceedings, and it is one of the most commonly held and least used covers there is. Check the policy before assuming the cost is yours. Means-tested legal aid applies here as elsewhere.
What to take to the first meeting
The summons or settlement proposal itself, with the date on it; the measurement report if you have it; your licence and its history; and a short, plain account written the same day you remember it. Ten minutes of that is often enough for a firm to tell you whether contesting is realistic.
