Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 11406 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee
SC 15, Interchangeability of components of commercial vehicles and buses.
This second edition cancels and replaces the first edition (ISO 11406:1993), which has been technically revised.
Annexes A and B of this International Standard are for information only.

INTERNATIONAL STANDARD ISO 11406:2001(E)
Commercial road vehicles — Mechanical coupling between towing
vehicles with rear-mounted coupling and drawbar trailers —
Interchangeability
1 Scope
This International Standard specifies the requirements for the various elements and dimensions of towing vehicles
with rear-mounted coupling and of drawbar trailers, to ensure interchangeability.
NOTE Annex B gives examples of different configurations of vehicle combinations; this International Standard deals only
with No. B.1.1.
This International Standard is applicable to road trains for commercial transport of cargo of the greatest possible
variety; it does not cover dedicated or special combinations. Nor does it specify limitations of maximum gross mass
and overall dimensions, which are generally laid down by legislative requirements.
Vehicles whose couplings form the subject of this International Standard are not interchangeable with vehicles
[1]
whose couplings are mounted forward and below (which form the subject of ISO 11407 ).
