Use this bank to prepare for the Greece Category C lorry theory test.

About the Greece Category C Theory Exam
The Greece Category C driving theory examination is the official assessment for drivers extending their licence to goods vehicles over 3,500 kg maximum authorised mass. Regional Transport and Communications Directorates administer it on the computerized M.S.TH.E.Y.O. system, drawing the questions from Ερωτηματολόγιο 4 of ministerial decision 50984/7947/2013. This practice bank covers the same official syllabus - vehicle dimensions and masses, pneumatic braking, load securing, EU driving and rest times under Regulation (EC) 561/2006, the digital tachograph, Greek Highway Code rules for lorries, and defensive driving - as an English-language MCQ study adaptation rather than a reproduction of the official questionnaire.

Frequently Asked Questions
What is the official format of the Greece Category C theory test?
Article 22 of ministerial decision 50984/7947/2013 sets it at 10 questions from Ερωτηματολόγιο 4, the lorry questionnaire, taken on the Ministry's M.S.TH.E.Y.O. computers. Each question offers three answers of which one is correct, the paper lasts 15 minutes, and a candidate passes with every answer correct or at most one wrong.
How does this practice bank differ from the official examination?
It is an English-language MCQ study adaptation of the official syllabus, not a translation or a simulation of the official paper. It runs to 100 questions with four options each, whereas the official test is 10 questions with three options each. Use it to learn the material; the format itself is best rehearsed on the Ministry's own questionnaire through your driving school.
What are the prerequisites for Category C in Greece?
A valid Category B licence, normal residence in Greece, fitness certificates from doctors of at least two specialities, and at least 15 theory and 15 practical lessons at a licensed driving school. The minimum age is 21, or 18 on the Mitos route that couples the licence with the Certificate of Professional Competence (P.E.I.).
In what languages is the official Greek Category C theory test offered?
Article 22 of the ministerial decision makes the questionnaires available in Greek, English, Albanian and Russian, and also in Greek with audio through headphones. The Mitos procedure confirms the same four languages when the theory examination is scheduled.
What happens after passing the Category C theory test?
Candidates go on to the practical test of skills and behaviour in a Category C training vehicle. Where the P.E.I. is being obtained at the same time, its separate theory examination of 60 questions plus case studies and its practical test must also be passed before the practical driving test can be scheduled.
What public fees apply to the Category C licence extension in Greece?
Mitos lists EUR 263.04 in total public fees for the extension from Category B with P.E.I.: EUR 193.04 single fee, EUR 15 for the category theory examination, EUR 15 for the practical test, EUR 20 for the P.E.I. theory examination and EUR 20 for the P.E.I. practical test.
