(b) the overall length of the combination of vehicles comprising the tractor and trailers does not exceed 22 metres.
(6) (a) The overall length of a vehicle or trailer shall be the distance between vertical planes at right angles to the longitudinal axis of the vehicle or trailer and passing through the extreme projecting points at the front and rear of the vehicle or trailer, and for that purpose—
(i) in calculating the overall length of a trailer, the drawbar shall be included;

(iii) in calculating the overall length of an articulated vehicle—
I. any load on the vehicle shall be deemed to form part of the vehicle save where the vehicle is carrying poles for use in connection with the provision of telephone or electricity services,
II. the longitudinal axes of the drawing and drawn components shall be in the same vertical plane.
(b) The overall length of a combination of vehicles shall be the distance between vertical planes at right angles to the longitudinal axes of the drawing and drawn components comprised in such combination (while such axes are in the same vertical plane) and passing through the extreme projecting points at the front and rear of the combination.
(7) The provisions of this article relating to the overall length of a combination of vehicles shall not operate so as to prohibit the towing of a broken down vehicle which is being towed, in consequence of the breakdown, to the nearest convenient place of safety or repair.
(8) A load, other than poles intended for use in connection with telephone or electricity services, on a vehicle which is not drawing a trailer, or on the rearmost trailer in a combination of vehicles, shall not project more than 3 metres to the rear beyond the rearmost point of such vehicle or trailer.
(9) Where a load (including an implement carried by a tractor) projects more than 1 metre to the rear beyond the rearmost point of a vehicle or the rearmost trailer in a combination of vehicles, a warning device (being either a red flag or cloth at least 300 millimetres square, or a rigid device having a surface of a similar area coloured red or in two colours, one of which is red and the other of which is lighter than red) shall be carried at the rear of the load during the day time".

EXPLANATORY NOTE.
These Regulations provide for increased maximum permitted vehicle weight limits in respect of mechanically propelled vehicles and their trailers and include revised maximum weight limits in respect of axles and individual wheels. The maximum permitted vehicle weight limits are subject to detailed controls in relation to axle spacings. Provision is also made for increased maximum permitted lengths in respect of vehicles and combinations of vehicles. The Regulations also provide for axles to be weighed when a vehicle is moving on a weighing machine.
