Carriage other than by road

If the vehicle carrying out a transport operation subject to the requirements of ADR is conveyed over
a section of the journey otherwise than by road haulage, then any national or international regulations
which, on the said section, govern the carriage of dangerous goods by the mode of transport used for
conveying the road vehicle shall alone be applicable to the said section of the journey.

In the cases referred to in 1.1.4.5.1 above, the involved ADR Contracting Parties may agree to apply
the requirements of ADR to the section of a journey where a vehicle is conveyed otherwise than by
road haulage, supplemented, if they consider it necessary, by additional requirements, unless such
agreements between the involved ADR Contracting Parties would contravene clauses of the
international conventions governing the carriage of dangerous goods by the mode of transport used for
conveying the road vehicle on the said section of the journey, e.g. the International Convention for the
Safety of Life at Sea (SOLAS), to which these ADR Contacting Parties would also be contracting
parties.
 
These agreements shall be notified by the Contracting Party which has taken the initiative thereof to
the Secretariat of the United Nations Economic Commission for Europe which shall bring them to the
attention of the Contracting Parties.

 

In cases where a transport operation subject to the provisions of ADR is likewise subject over the
whole or a part of the road journey to the provisions of an international convention which regulates
the carriage of dangerous goods by a mode of transport other than road carriage by virtue of clauses
extending the applicability of that convention to certain motor-vehicle services, then the provisions of
that international convention shall apply over the journey in question concurrently with those of ADR
which are not incompatible with them; the other clauses of ADR shall not apply over the journey in
question.

Application of standards

Where the application of a standard is required and there is any conflict between the standard and the
provisions of ADR, the provisions of ADR take precedence. The requirements of the standard that do
not conflict with ADR shall be applied as specified, including the requirements of any other standard,
or part of a standard, referenced within that standard as normative.
