ISO 11406:2001

Commercial road vehicles — Mechanical coupling between towing vehicles with rear-mounted coupling and drawbar trailers — Interchangeability

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

whose couplings are mounted forward and below (which form the subject of ISO 11407 [1]).
