General information

General overview

Roadworthiness of a vehicle is attested by a single document, the roadworthiness certificate (DTE in Greek). If no major or dangerous deficiencies are detected, a proof of test, called the mark indicating proof of technical test (ESTE, in Greek) is attached to the vehicle by the public or private testing centre for motor vehicles (the KTEO). Certificates issued after 20/05/2018 bear the EU codes described in Annexe II of directive 2014/45/EU. The vehicle driver must carry the vehicle registration document and the roadworthiness certificate. The roadworthiness certificate is valid up to one week after the expiry date written on it. The authenticity of the roadworthiness certificate authenticity can be checked with the Greek Ministry of Infrastructure and Transport, which holds the KTEO test results. The check is done using the certificate serial number and the KTEO code number, both on the upper right part of the document. The proof of test is attached to the rear registration plate of the vehicle. The proof of test indicates the year of the test and, on the upper part of the document, the month when the next periodic test is due.
