Trial will be held in french, although I think in this case, dutch speaking ppl will have a translator.

And, yes, laws are federal (at least in this case), so, same laws do apply.

Laws are certainly not always federal, but in this case they are.
It’s a court of assises, with a jury (don’t know the English term), a remainder from the code napoleon.

But trafic rules are different in wallonia, flanders and brussels!!! Transportation, economy, social affairs, agriculture, trade … are not federal. Though Belgium is not a confederation (yet), apart from defence and foreign affairs there’s really not much decided anymore on a federal level, most is local or EU.
Small detail, the Belgian constitution doesn’t say that Belgium has 3 official languages, it says there’s one official language in each community, which means that, if a Flemish gets caught in Wallonia, and he has to go to trial, he better learns some French (or asks for a translator) because French is the only official language! (Brussels being the exception were both French or Dutch or bilingual trials can be requested). 😎

And as the trial takes place in Luxembourg, Wallonia, the trial will be in French, translators are optional.
