(3)Following the request of the European Parliament and with the aim of simplifying and accelerating the adoption of type-approval legislation, a new regulatory approach has been introduced in Union vehicle type-approval legislation in accordance with which the legislator in the ordinary legislative procedure sets out the fundamental rules and principles only and delegates the power to adopt delegated acts concerning further technical details to the Commission. With regard to substantive requirements, this Regulation should therefore lay down only fundamental provisions on functional safety, occupational safety and environmental performance and delegate to the Commission the power to lay down the technical specifications in delegated acts.
