Transport of Dangerous Goods by Road (ADR General)
What is ADR?
ADR is the acronym given to The European Agreement Concerning the International Carriage of Dangerous Goods by Road, which was made at Geneva in 1957 by United Nations Economic Commission for Europe, and amended April 1985.
The key article in the agreement is the second, which says that apart from some excessively dangerous goods, other dangerous goods may be carried internationally in road vehicles subject to compliance with:
- the conditions laid down in Annex A for the goods in question, in particular as regards their packaging and labelling; and
- the conditions laid down in Annex B, in particular as regards the construction, equipment and operation of the vehicle carrying the goods in question.
Annexes A and B have been regularly amended and updated since the entry into force of ADR. These annexes were entirely revised and restructured between 1992 and 2000, and a first version of the restructured annexes entered into force on 1 July 2001.
Ireland is a contracting party to ADR.
The most recent amendment to the annexes was on the 1 January 2017.
What provisions are detailed in the ADR 2017 Annexes?
Annex A details the general provisions and provisions concerning dangerous articles and substances which are divided into the following parts:
- Part 1 – General Provisions
- Part 2 – Classification
- Part 3 – Dangerous goods list, special provisions and exemptions related to limited and excepted quanitities
- Part 4 – Packing and tank provisions
- Part 5 – Consignment procedures
- Part 6 – Requirements for the construction and testing of packagings, intermediate bulk containers (IBCs), large packagings and tanks
- Part 7 – Provisions concerning the conditions of carriage, loading, unloading and handling
Annex B details the provisions concerning transport equipment and transport operations which are divided into two parts as follows:
- Part 8 – Requirements for vehicle crews, equipment, operation and documentation
- Part 9 – Requirements concerning the construction and approval of vehicles
What is classified as “Carriage of Dangerous Goods”?
Under the European Communities (Carriage of Dangerous Goods by Road and Use of Transportable Pressure Equipment) Regulations 2011 to 2017 “the carriage of dangerous goods by road” is defined as any road transport operation performed by a vehicle wholly or partly on public roads, including the activity of loading and unloading, packing and filling, covered by the ADR, but does not include transport wholly performed within the perimeter of an enclosed area not open to the public.
What goods are classified as 'dangerous' for carriage by road?
The classes of dangerous goods according to ADR are the following:
|Class Number||Substance / Article Description|
|Class 1||Explosive substances and articles|
|Class 3||Flammable liquids|
|Class 4.1||Flammable solids, self-reactive substances, polymerizing substances and solid desensitised explosives|
|Class 4.2||Substances liable to spontaneous combustion|
|Class 4.3||Substances which, in contact with water, emit flammable gases|
|Class 5.1||Oxidising substances|
|Class 5.2||Organic peroxides|
|Class 6.1||Toxic substances|
|Class 6.2||Infectious substances|
|Class 7||Radioactive material|
|Class 8||Corrosive substances|
|Class 9||Miscellaneous dangerous substances and articles|
Each entry in the different classes has been assigned a unique, 4-digit UN number, which may be either specific to an individual substance or collective to a product or substance type.
The UN numbers are assigned to different transport categories from 0 to 4 and this will influence the maximum amount of the goods that can be carried at any one time.
How do I determine the requirements for particular substances or articles?
Chapter 3.2 of the ADR contains a Dangerous Goods List. This is a table which contains a list of dangerous goods by name and description, their UN numbers, classification, transport categories and all the relevant codes for packaging, labelling, special provisions, carriage in bulk, carriage in tanks, etc.
ADR Chapter 3.1 and the introductory paragraphs of Section 3.2.1 provide explanatory notes regarding each of the columns of the dangerous goods list. The relevant section of the ADR that details the requirements for each of the codes is provided in the column header.

How is the ADR enforced in Ireland?
In Ireland the ADR is enforced by the European Communities (Carriage of Dangerous Goods by Road and Use of Transportable Pressure Equipment) Regulations 2011 to 2017.
These regulations are based on the provisions outlined in three directives:
The Regulations principally apply to the carriage of dangerous goods by road, in tanks, in bulk and in packages, in accordance with the provisions contained in the technical Annexes to the ‘European Agreement Concerning the International Carriage of Dangerous Goods by Road' (ADR). They impose duties on the various participants associated with the carriage of the dangerous goods, including the consignor, carrier, driver, packer, loader, filler, unloader, tank container or portable tank operator, vehicle crew, consignee, safety adviser, inspection body or any other person with a duty under the relevant transport statutory provisions. They refer to the ADR which contains requirements for the vehicles, tanks, tank containers, receptacles and packages containing the dangerous goods during their carriage. They require that those involved in the carriage of the dangerous goods by road (including drivers and those responsible for the packing, loading, filling and unloading of dangerous goods) be adequately trained and, in the case of drivers, hold a certificate of such training.
The Regulations also contain provisions on an EC harmonised approach to the road checks aspect of enforcement (Directive 95/50/EC).
In 2011 Directive 2010/35/EU on transportable pressure equipment was transposed in Irish law and was incorporated in the national regulations concerning the carriage of dangerous goods by road (see section on TPED).

Who are the competent authorities for ADR in Ireland?
The following are the ‘Competent Authorities’:
- Road Safety Authority (RSA) for technical examination of vehicles and issuing of certificates of approval
- National Standards Authority of Ireland (NSAI) for testing of receptacles and tanks
- Irish National Accreditation Board (INAB) for accreditation of inspection bodies
- Minister for Justice and Equality for all matters relating to the carriage by road of explosives of the ADR Class 1
- Environmental Protection Agency (EPA) for all matters relating to the carriage by road of radioactive materials of the ADR Class 7
- National Roads Authority (NRA) for matters relating to the classification of tunnels as required
- Health and Safety Authority (HSA) for all other functions required to be performed by a competent authority under the Regulations
Can the transport document required by ADR be incorporated into another document or split between more than one document?
Yes. If all the relevant information as required by ADR 220.127.116.11.1, is situated within a document(s) which may double as an invoice or waste C1 form or another document, this is acceptable provided the ADR transport document information is clear and follows the requirements set out in ADR.
How much waste electrical goods are allowed for carriage by road without ADR applying?
Under ADR if the electrical goods, e.g. transformers or condensers etc, contain PCB’s – Polychlorinated Biphenyls (liquid or solid) or PHB’s Polyhalogenated Biphenyls (liquid or solid) with UN numbers 2315, 3151, 3152 or 3432 then all the requirements of ADR apply for any quantity transported and the driver would have to hold valid ADR Driver Training Certificate covering Class 9 as the goods would come under Transport Category 0.
It should also be noted that uncleaned empty containment vessels for such apparatus containing substances assigned to UN 2315, 3151, 3152 cannot be accepted for carriage.
However if the electrical goods do not contain dangerous substances then they are exempt from any of the requirements of ADR, the consignor has the obligation to classify the waste.
Where can I find information on the amount of other substances I can carry, by road, without ADR applying?
To find out how much of a substance can be carried you must first find out the UN number assigned to that particular substance.
18.104.22.168.3 of ADR shows a table of Transport Categories, the UN numbers that fall into those categories and the corresponding maximum total quantity per transport unit of dangerous goods that can be carried before having to apply all provisions of ADR. Note however some provisions remain and advice should be sought from a safety adviser.
22.214.171.124.4 of ADR details the provisions, which must be made if goods are to be carried together that are belonging to different Transport Categories.
Other exemptions apply and for a accurate assessment for your business you should contact a safety adviser.
Who is classified as the consignor?
Regulation 2(9) of S.I. No.349 of 2011, defines “consignor” as the person who consigns dangerous goods either on its own behalf or for a third party and shall be construed as -
(i) any person who having a place of business in the State supplies, whether as a principal or agent for another, dangerous goods for carriage by road, or
(ii) if no person satisfies the requirements of clause (i), the consignee of those goods in so far as that person has control over the carriage of those dangerous goods in the State.
Also Regulation 2(9) states if the transport operation is carried out under a contract for carriage, “consignor” means the consignor according to the contract for carriage.
What do I need to do if I want to drive a vehicle that carries dangerous goods?
If you wish to drive a vehicle for the purpose of transport of dangerous goods, you must hold a valid ADR Training Certificate. To obtain the appropriate certificate, you must first attend an approved Basic and/or Tanker Specialisation Driver Training Course and then successfully complete an exam. The management of these examinations was awarded to the Chartered Institute of Logistics, Ireland (CILT) in April 2007. For further information on applying for these exams please follow the link below;
Does the transport of asbestos material come under the ADR?
Yes, though there are some exemptions. A guide to the transport of Asbestos, which deals with classification, carriage in limited quantities, carriage of goods over or below the threshold quantities, packaging and labelling, vehicle equipment and marking, documentation, DGSA and relevant legislation is available from the HSA. See relevant guidance under Class 9 Dangerous Goods.
Are there specific requirements for transporting Ammonium Nitrate based fertilisers?
Yes, some Ammonium Nitrate based fertilisers are classified as “dangerous goods” and therefore the ADR and the 2011 Regulations apply in certain situations.
The driver will require a valid ADR training certificate and other ADR requirements will apply in the following situations:
- The fertiliser is classed as an oxidising substance, Class 5.1 UN 2067
- Calcium Ammonium Nitrate fertiliser that has greater than 80% Ammonium Nitrate (i.e. +>28% N)
The carriage of goods classed as UN 2071 is not subject to ADR and may be carried without restriction.
Are there any exemptions for farmers who transport Ammonium Nitrate based fertilisers by road?
Agricultural or forestry tractors or indeed any mobile machinery can draw any quantity of UN 2067 as these are not ‘Vehicles’ or ‘Transport equipment’ and are therefore exempt by definition under Regulation 2 (1) of SI 349 of 2011.
How do I know what should be contained in spill kits?
Different goods and substances will have a variety of different emergency procedures in the case of spills and leaks. A spill kit is the equipment that must be contained on the vehicle for use in an emergency situation. There is no standard spill kit. Equipment will vary dependant on the goods being carried.. The carrier of dangerous goods must issue instructions in writing/ TREM card (transport emergency card) which specifies the emergency procedures required for the dangerous substances in question as well as personal and vehicle equipment. The carrier must ensure that all equipment necessary to complete these procedures are provided on the vehicle.
What constitutes a Contract for carriage?
Regarding duties of consignors, where a contract for carriage exists, it would be expected that this document would be in the form of a written contract, agreed and duly signed by all implicated participants and would stipulate the terms of the contract of carriage. If the intention of the contract is for the original consignor to bear the duties of consignor throughout the various stages of "re-consignment" and if applicable the return of uncleaned packaging/tanks etc, the extent of that undertaking must be clear and unambiguous within the contract making appropriate reference to the ADR and national regulations as appropriate.
Having no contract for carriage in place automatically re-assigns consignor duties to those in the supply chain according to Regulation 2(9).
If there is no consignor established within the State, who is deemed the consignor?
The Consignee. See Regulation 2(9), SI 349 of 2011.
Do manufacturers who outsource their distribution of high consequence dangerous goods need to address security plan requirements?
Manufacturers who outsource their distribution must still comply with security plan provisions as they are consignors.
Is there guidance on security requirements?
The HSA has no specific guidance on security requirements other than what is stipulated in the ADR. However, there is a number of guidance documents available on the UK Dept. for Transport web site www.dft.gov.uk
The UK Draft guidance on security of dangerous goods publication is a comprehensive guide and may be used when considering specific security plans.
What are the requirements for fire extinguishers for transport units carrying dangerous goods?
Section 8.1.4 of ADR 2011 specifies fire extinguisher requirements for transport units carrying dangerous goods.
The table below outlines the various transport units and the specific fire extinguisher requirements:
- Fire Extinguisher requirements for transport units under ADR regulations
Section 8.1.4 of ADR 2011 specifies fire extinguisher requirements for transport units carrying dangerous goods

When do I need ADR driver training or when must I use a trained ADR driver?
You must be or you must use a suitably trained driver certified to drive vehicles carrying dangerous goods subject to national legislation/ADR. As there are exemptions to the rule you may require advice from a dangerous goods safety adviser (DGSA) to establish whether formal certification is necessary in your circumstance.
In general all tank vehicle activity requires a driver certified for carriage in tanks and for the dangerous goods being carried. For packaged dangerous goods there are thresholds under which a certified driver may not be necessary. Guidance on the various exemptions that may be available to you, and your relevant training requirements, is provided in Chapters 5 and 6 of our ADR Guide for Business (link below)
Note it is a legal duty for consignors of dangerous goods to inform the carrier of the nature and quantity of the dangerous goods to be carried.
