A Section 69 of the Road Traffic Act 1960
lays down the number of trailers which may be drawn by different types of vehicle. In the case of a goods vehicle (i.e. a "motor car" or "heavy motor car") the number of trailers which may be drawn is limited to one. As a result a rigid vehicle would not normally be allowed to tow an articulated vehicle because the tractive unit and semi-trailer would then be considered to be two trailers.
However. paragraph 3 of Section 69 does permit a rigid vehicle to tow an articulated outfit, i.e. a tractive unit and semi-trailer which has broken down when, providing the trailer is unloaded, it is then considered on this occasion to be a single trailer.
It follows, therefore, that a complete artic outfit, i.e. tractive unit and semi-trailer, is not legally permitted to tow another vehicle.
