Sign S-400: Itinerario europeo

What it means

The S-400 sign identifies a European route. It informs that the road forms part of a signed European route, helping you recognise trip continuity and the relationship with other international itineraries. It does not by itself change traffic rules, limits, priorities, or the Spanish category of the road. It usually appears on direction panels, confirmation panels, markers, or accesses where the route being followed is indicated. When you see it, use it as an orientation reference and continue paying attention to the specific signing of the stretch. In the test they often ask what the European number or panel identifies, not a manoeuvre obligation.
