Article 3
1. A Member State may not reject or prohibit the use in its territory: - in international traffic, of vehicles registered or put into circulation in any other Member State for reasons relating to their weights and dimensions, - in national traffic, of goods vehicles registered or put into circulation in any other Member State for reasons relating to their dimensions, provided that such vehicles comply with the limit values specified in Annex I. This provision shall apply notwithstanding the fact that: (a) the said vehicles are not in conformity with the requirements of that Member State with regard to certain weight and dimension characteristics not covered by Annex I; (b) the competent authority of the Member State in which the vehicles are registered or put into circulation has authorized limits not referred to in Article 4 (1) exceeding those laid down in Annex I. 2. However, paragraph 1 (a) shall not affect the right of Member States, with due regard to Community law, to require vehicles registered or put into circulation in their own territory to be in conformity with their national requirements on weight and dimension characteristics not covered by Annex I. 3. Member States may require conditioned vehicles to carry an ATP certificate or ATP certification plate provided for in the Agreement of 1 September 1970 on the international carriage of perishable foodstuffs and on the special equipment to be used for such carriage.
