> In a "free" market why would a Bulgarian be forced to operate only near Bulgaria? But this isn't about a Bulgarian person - this is about a truck registered in Bulgaria. That means that the registration fees and taxes, which are a national responsibility and are not at the EU-level, are paid in Bulgaria. So if you only drive the truck in, say, France, you're essentially evading French taxes for the said truck.
