"the 1986 Regulations" means the Road Vehicles (Construction and Use) Regulations 1986(2);
"articulated bus or coach" means a single vehicle which is a bus or coach consisting of 2 or more rigid sections which-�
articulate relative to one another;
are intercommunicating so that passengers can move freely between them; and
are permanently connected so that they can only be separated by an operation using facilities normally found only in a workshop;
"articulated vehicle" means a tractor unit to which a semi-trailer is attached;
"axle weight" means the sum of the weights transmitted to the road surface by all the wheels of an axle, and for the purpose of calculating axle weight the 2 axles comprised in a tandem axle and all the axles comprised in a triaxle shall be treated as one axle;
"centre-axle trailer" means a trailer having only a single axle or group of axles which is positioned at or close to the centre of gravity so that, when the trailer is uniformly loaded, the static vertical load transmitted to the towing vehicle does not exceed 10 per cent of the maximum authorised weight for the axle or group of axles or 1000 kg, whichever is the less;
"kg" means kilograms;
"m" means metres;
"maximum authorised weight" in relation to a vehicle, vehicle combination or axle means the maximum authorised weight for the vehicle, vehicle combination or axle determined in accordance with these Regulations;
"rigid motor vehicle" means a motor vehicle which is not a tractor unit or an articulated bus;
"road friendly suspension" means a suspension system whereby at least 75 per cent of the spring effect is produced by air or other compressible fluid under pressure or suspension recognised as being equivalent within the Community as defined in Annex II of Council Directive 96/53/EC(3);
"semi-trailer" means a trailer which is constructed or adapted to be drawn by a tractor unit and includes a vehicle which is not itself a motor vehicle but has some or all of its wheels driven by the drawing vehicle;
"steering axle" means an axle that can be positively steered by the action of the driver;
"tandem axle" means a group of 2 axles not more than 2.5m apart so linked together that the load applied to one axle is applied to the other; references to a "driving tandem axle" include a tandem axle where either or both the axles comprising the tandem axle are driven and references to a "non-driving tandem axle" are to a tandem axle where neither of the axles comprising it is driven;
"tractor unit" means a motor vehicle by which a trailer partially superimposed on it may be drawn so that, when the trailer is fully loaded, not less than 20 per cent of its load is borne by the drawing vehicle;
"triaxle" means-�
a group of 3 axles in which no axle is more than 3.25m apart from any other axle; or
a group of more than 3 axles in which no axle is more than 4.6m from any other axle,
and in either case so linked together that the load applied to one axle is transferred to both or all the others; and
"vehicle combination" means an articulated vehicle or a rigid motor vehicle drawing a trailer.
(2) For the purposes of these Regulations the distance between any 2 axles of a vehicle or vehicle combination shall be taken to be the shortest distance between the line joining the centres of the areas of contact with the road surface of the wheels of one axle and the line joining the centres of the areas of contact with the road surface of the wheels of the other axle.
(3) In these Regulations, except where otherwise specified,-�
(a)a reference to a numbered regulation is a reference to the regulation in these Regulations so numbered;
(b)a reference to a numbered paragraph is a reference to the paragraph so numbered in the regulation or the Schedule in which the reference occurs;

4.-(1) Subject to paragraph (2) and regulation 5, no vehicle to which these Regulations apply and which is of a description specified in a Schedule to these Regulations shall be used on a road if-�
(a)the weight of the vehicle exceeds the maximum authorised weight for the vehicle determined in accordance with Schedule 1;
(b)where the vehicle is used as part of a vehicle combination, the weight of the combination exceeds the maximum authorised weight for the combination determined in accordance with Schedule 2; or
(c)the axle weight of any axle of the vehicle exceeds the maximum authorised axle weight for that axle determined in accordance with Schedule 3.
(2) A vehicle to which any of the provisions of regulations 75 to 79 of the 1986 Regulations apply, so long as it is so used that those provisions are complied with, shall be taken to comply with these Regulations.
5. Nothing in these Regulations shall prejudice or affect regulation 80 of the 1986 Regulations and a person using or permitting a vehicle to be used contrary to the provisions of that regulation commits an offence even if the weights authorised by these Regulations are not exceeded.

(This note is not part of the Regulations)
These Regulations make new provision for the weights of wheeled motor vehicles and trailers which fall within category M2, M3, N2, N3, O3 or O4 of the vehicle categories defined in Annex II of Council Directive 70/156/EEC as amended. They do not apply to vehicle combinations that meet the requirements for combined transport in Schedule 11A to the Motor Vehicles (Construction and Use) Regulations 1986.
Regulation 4 introduces the three Schedules, which respectively lay down maximum authorised weights for individual vehicles (Schedule 1), for vehicle combinations (Schedule 2) and for axle weights (Schedule 3), and prohibits the use of a vehicle on a road if any of these weights are exceeded.
A vehicle which complies with the provisions by regulations 75 to 79 of the 1986 Regulations is taken to comply with these Regulations (regulation 4(2)).
The new weight limits are, in accordance with regulation 5, also subject to the overriding limit in regulation 80 of the 1986 Regulations, to which amendments are made by the Road Vehicles (Construction and Use) (Amendment) (No. 7) Regulations 1998 (S.I. 1998/3112).
This Regulation has been notified to the European Commission pursuant to Directive 83/189/EEC of 28th March 1983 laying down a procedure for the provision of information in the field of technical standards and regulations (OJ 1983 L109, p.9) as amended by Council Directive 88/182/EEC of 22nd March 1988 (OJ 1988 L81, p.75) and European Parliament and Council Directive 94/10/EEC of 23rd March 1994 (OJ 1994 L100, p.30).
1988 c. 52; section 41 was amended by the Road Traffic Act 1991, Schedule 4, paragraph 50 and Schedule 8.
S.I. 1986/1078; relevant amending instruments are S.I. 1987/676; 1992 /2016; 1994/329 and 1997/1096.
