There are two different regulations for Daytime Running Lights on automobiles that are operated in Europe.
In the Scandinavian countries, it is obligatory that all exterior lighting be illuminated at full power at all times.
In the other European countries, it is permitted that only the headlights be on (if headlights, as opposed to dedicated DRL lights, are used for DRL purposes), and they are permitted to be operated at reduced power. That is the same policy as Canada... the USA does not require DRLs by law, but many new vehicles sold in the USA are provisioned with DRLs anyway. The practice of operating headlights used as DRLs at reduced power is rapidly falling by the wayside, because only incandescent lamps benefit from being operated at less than full power.
On most vehicles, the configuration of the DRLs can be switched via software coding to comply with either the Scandinavian or Rest of Europe (and Canada) spec.
I don't know if the DRL regulations apply to trucks, or if so, what the rules are, because trucks are covered under a different set of rules.
