The question and answer document aims to clarify the operation of the international whole vehicle type approval system. This question would confirm that a Contracting Party may apply additional requirements taken from a UN Regulation beyond those regulations specifically required under a limited whole vehicle approval (L-IWVTA). The L-IWVTA partially applies the list of requirements for a “Universal International Whole Vehicle Approval” (U-IWVTA). A CP could list UN Regulations required for an L-IWVTA and then notify WP.29 of additional requirements taken from other UN Regulations.
