low loader a semi-trailer which is constructed and nor mally used for the carriage of engineering equipment so constructed that the major part of the load platform does not extend over or between the wheels and the upper surface of which is below the height of the top most point of the tyres of those wheels, measured on level ground and when–
(a) any adjustable suspension is at the normal travelling height,
(b) all pneumatic tyres are suitably infl ated for use when the vehicle is fully laden, and
(c) the semi-trailer is unladen,

stepframe low loader a semi-trailer (not being a low loader) which is constructed and normally used for the carriage of engineering equipment and is so constructed that the upper surface of the major part of the load platform is at a height of less than 1m above the ground when measured on level ground and when–
(a) any adjustable suspension is at the normal travelling height,
(b) all pneumatic tyres are suitably inflated for use when the vehicle is fully laden, and

3B 
An articulated vehicle, the semi-trailer of which is a low loader. 18”
(c) in column 2 of item 7, there shall be inserted after the words “after 1st of May 1983” the words “which does not meet the requirements of paragraph (6) and is not a low loader”; and
(d) after item 7 there shall be inserted the following item–“

7A 
A composite trailer drawn by–
(a) a goods vehicle being a motor vehicle having a maximum gross weight exceeding 3500 kg; or

(4) For paragraph (6) there shall be substituted the following paragraphs–“
(6) The requirements of this paragraph, in relation to a semi-trailer, are that–
(a) the longitudinal distance from the axis of the king pin or if there is more than one king pin, the foremost one, to the rear of the semi-trailer does not exceed–
(i) 12.5m in the case of a car transporter, or
(ii) 12m in any other case; and
(b) no point in the semi-trailer forward of the transverse plane passing through the axis of the king pin or, if there is more than one king pin, the rearmost one, is more than–
