Judgment_paragraph 31 · Isabel Maria Pinheiro Vieira Rodrigues de Andrade and Fausto da Silva Rodrigues de Andrade v José Manuel Proença Salvador and Others (C-514/16)

31As regards the concept of ‘use of vehicles’ within the meaning of Article 3(1) of that directive, it should be noted that this cannot be left to the assessment of each Member State but is an autonomous concept of EU law, which must be interpreted in the light, in particular, of the context of that provision and the objectives pursued by the rules of which it is part (see, to that effect, judgment of 4 September 2014, Vnuk, C‑162/13, EU:C:2014:2146, paragraphs 41 and 42).
