OBS_VALUE: Regulation (EU) 2018/1806 of the European Parliament and of the Council of 14 November 2018 lists the third countries whose nationals must be in possession of visas when crossing the external borders and those whose nationals are exempt from that requirement (Article 4). It provides for exemptions from visa requirements for air and sea crew. No specific reference to truck drivers has been found. However, under the previous Regime of Regulation 539/01 (EU), truck drivers have been interpreted to be subsumed thereunder (pursuant to the Ministry's interpretative circulars of 2011 and 2012). Under this regime, they were also granted multiple visas (2011 Circular, pg.163-164). For an unofficial version of Law 5038/2023, see:  https://www.kodiko.gr/nomothesia/document/873766/nomos-5038-2023
