# The Motor Vehicles (Designation of Approval Marks) Regulations 1979, Paragraph 15


Paragraph 2 above shall not apply to the marking shown in item 33, but the number shown outside and below the rectangle in the marking relating to that item shall be varied, where appropriate, so as to be the number of the relevant approval document preceded by—
(a) “00”, if approval has been granted on the basis of the tyres to which the approval applies being commercial vehicle tyres as defined in the EU Instrument referred to in column (3) in relation to that item;
(b) “02”, if approval has been granted on the basis of the tyres to which the approval applies being passenger car tyres as defined in that EU Instrument;
The number shall be close to and outside the rectangle but may be above or below or to the left or to the right of it but shall be aligned so as to be read in the same direction as the number inside the rectangle. The suffix “-s” shall be added to the number to show that the tyre complies with the noise emission requirements in Annex V of the EU Instrument referred to in column (5) of Schedule 4.
