“engineering plant” means movable plant or equipment which does not comply in all respects with the requirements of the Rules, and which is either —

(a)	a motor vehicle or trailer specially designed and constructed for use in connection with engineering operations and which is only used on a road in proceeding to and from the site of such operations or when actually engaged in such operations and carrying no load other than its own necessary gear or equipment;
(b)	a trailer (including a tar boiler or road material mixing apparatus but excluding any other trailer used for the carriage of road material or similar burden), used for the purposes of, or a living van used in connection with, the construction, maintenance and repair of roads; or

Vehicles for conveyance of abnormal indivisible loads

3. The Minister has authorised the use on roads of motor vehicles and trailers specially designed and constructed, and used only, except as provided in paragraph 6, for, or empty in connection with, the conveyance of abnormal indivisible loads notwithstanding that such vehicles do not comply in all respects with the Rules, subject to the conditions and restrictions contained in paragraphs 5, 6, 7, 8 and 9 and also to the conditions and following restrictions:

(a)

in the case of a motor vehicle all the Rules, other than rules 7, 10, 11, 42, 94 and 95, shall apply;

(b)

in the case of a trailer all the Rules, other than rules 6, 7, 10, 11, 15, (4), and (5), 42, 94 and 96, shall apply;

(c)

every such vehicle shall be a wheeled vehicle;

(d)

the overall width of any such motor vehicle shall not exceed 2.9 metres and the overall width of any such trailer shall not exceed 2.9 metres except where a greater width is necessary for the safe conveyance of the particular loads carried by that trailer;

(e)

(i)	every such motor vehicle shall be equipped with pneumatic tyres or tyres of soft or elastic material;
(ii)	all wheels of any such trailer not equipped with pneumatic tyres or tyres of soft or elastic material shall have a smooth tread of not less than 250 mm. in width in contact with the road surface and shall have the edges of such tread rounded to a radius of not less than 12 mm. and not more than 25 mm.;
	Provided that all wheels of any such trailer constructed after 1st January 1938, and as from 1st January 1949 all wheels of every such trailer, shall be fitted with pneumatic tyres or tyres of soft or elastic material;

(f)

the total weight transmitted to the road surface by any wheels not fitted with pneumatic tyres of any such motor vehicle or trailer in line transversely shall be such that the average weight per 25 millimetres width of tyre in contact with the road surface shall not exceed 30 kilograms;

(g)

every such motor vehicle or trailer with more than 4 wheels, and every such trailer having more than two wheels in contact with the ground being part of an articulated vehicle shall be provided with such compensating arrangement as will ensure that all the wheels will remain in contact with the road surface and under the most adverse conditions will not be subjected to abnormal variations of load; provided that this requirement shall not apply to any steerable wheel of a motor vehicle if the load on such wheel does not exceed 2½ tonnes;

(h)

every such vehicle shall be equipped with an efficient braking system the brakes of which act upon not less than half the total number of wheels of the vehicle and such brakes shall at all times while the vehicle is used on a road be maintained in good and efficient working order and shall be properly adjusted.
