Visit of a President

The Head of State of Mum's home country is visiting Sweden for a couple of days. roads where he is supposed to travel have been closed for ordinary traffic for security reasons. He is not a King, nor an Emperor, but merely a President. Mum says this is better than a King or Emperor, but I disagree. Nevertheless, he is a Head of State and it is right to treat him as such. Thus, it must be all right to close roads.
