Exemptions arise in three ways,
1. ADR itself has exemptions set out in part 1.1.3. The main ones are:
2. This is a limited exemption permitted by ADR 126.96.36.199 which is discussed in ADR, CDG and DGSA . It has been implemented by Regulation 3(j)
3. LQ refers to small receptacles (typically of the sort that go into the retail distribution chain) which are packed in boxes or on shrink-wrapped trays.
4. The principle behind LQ is that an acceptable level of safety is assured providing the receptacles are in a box or shrink-wrapped tray. Retail distribution of LQ packages that have been "broken down" is allowed, subject to certain conditions. Subject to those conditions being met, no other requirements of ADR apply. Note however that from 1 January 2011 there are requirements to mark certain transport units when carrying more than 8 tonnes of LQ packages. See ADR 3.4.10
5. Dangerous goods are assigned an LQ “maximum receptacle size” category (Column 7a of Table A in ADR). For some substances this figure is 0, and in these cases there is no LQ exemption.
6. 3.4.2 and 3.4.3 specify the maximum gross mass of the package into which the inner receptacle is placed. This is 30kg except for shrink wrapped trays where the limit is 20 kg)
7. For limited quantity exemptions, the general requirements for packaging (to be of good quality and suitable etc) apply, but the packaging does not have to be "UN approved.3.4.4 has a particular requirement for certain Class 8 (corrosive) goods. There are particular LQ marking requirements (see ADR 3.4.7 and 3.4.8. Subject to those conditions, ADR does not apply to "limited quantities".
8. The limited quantity mark is:
or if an air mode journey is involved
Mark has to be minimum 100 mm x 100 mm unless package is too small. In that case the minimum is 50 mm x 50 mm
9. There is a requirement, under certain circumstances, for the marking of a transport unit which is carrying dangerous goods in "Limited Quantities". See ADR 2015 paragraphs 3.4.11 to 3.4.15.
10. Hydrochloric acid, UN 1789,(Strong PG II). From column 7a of Table A the maximum receptacle (inner packaging) size is 1 litre. which means that as long as the individual “bottles” are not larger than 1 litre, and the box does not weigh more than 30 kg, then, subject to the conditions outlined above, ADR does not apply.
11. The same substance more diluted (PG III) has a maximum “bottle” size of 5 litres. Again the maximum box weight is 30 kg.For example, typical 2 ½ litre bottles, packed four to a box, are within the LQ limit. The detailed packaging requirements do not have to be met but the LQ marking requirements apply (see above)
12. Solid caustic soda drain cleaner (UN 1823) has a maximum inner receptacle size of 1 kg. Again the maximum gross overall package is 30 kg.
13. Paint UN 1263 PG II. Cans up to 5 litres may be packed in a box not exceeding a gross weight of 30kg. Cans up to 1 litre may be on a shrink wrapped tray not exceeding a gross weight of 20 kg. Subject to the box or tray being marked as above ADR does not apply.
14. Orientation arrows have be applied to LQ packages when the conditions described at 188.8.131.52 apply.
15. ADR at 3.4.12 t requires information to be given to carriers in relation to consignments of “Limited Quantity (LQ) packages”. In certain circumstances (ADR 3.4.13), the vehicle has to be marked if carrying at least 8 tonnes of LQ packages.
16. "Excepted quantities" (EQ) is a relatively new concept for land transport of dangerous goods. It has been commonly used in air transport and the new rules will facilitate the road (and rail) transport elements of a journey that includes air mode. It is, though, also a standalone provision, and gives consignors an alternative for many dangerous goods.
17. Like LQ it requires goods to be in combination packages (e.g. a bottle in a box)
18. A new code (E0 – E5) appears in column 7(b) of table A. This links to paragraph 184.108.40.206 where what is allowed by the codes is set out. For example code E0 means that no EQ provisions are applicable. Code E1 means that the substance may be carried in inner packagings up to 30g or 30ml in outer packagings with a maximum net contents of 1000g or 1000ml - and so on for the other codes.
19. Unlike for LQ there are more prescriptive rules about packaging testing and for documentation.
20. The packages have to be marked with the "EQ Symbol" and documents (where carried) must state "dangerous goods in excepted quantities" and indicate the number of packages.
* (first) label number of the goods
** name of the consignor or consignee if not shown elsewhere on the package
21. Small load exemptions relate to the total quantity of dangerous goods carried in packages by the "transport unit" (usually the van or lorry, but also any trailer). It is the transport category (TC) that determines the load limits (thresholds). Many substances are assigned a packing group but these are not synonymous in all cases with TC. TC is given in column 15 of Table A in ADR (Chapter 3.2). If that is not available, the table at ADR part 220.127.116.11.3 needs to be consulted. Load limits for the different transport categories are given below. For convenience this has been amended in accordance with the derogation but it needs to be used with care.
22. Small load exemptions do not apply to tankers or bulk carriage.
23. If a vehicle is carrying under the small load threshold, many of the requirements of ADR are not applicable. The table below summarises the position. Some care needs to be taken, as "what is not exempted is still required". In most cases the remaining obligations are:
24. Note that use of these exemptions is optional. For example, a carrier may choose to display the orange plates as long as the vehicle is carrying dangerous goods.
25. All vehicle marks (orange plates) must be removed when no dangerous goods are being carried.
26. LPG. This is in transport category 2. The "small load threshold" is 333 kg and there is no LQ provision.. The result is that all cylinders count towards the load limit, but if that is less than 333 kg, the "minimum" ADR requirements apply.
27. Hydrochloric acid. Depending on its strength this is in transport category 2 or 3. The "small load threshold" is 333 or 1000 litres respectively. For TC 3, one 1000 litre IBC or five 200 litre drums or forty 25 litre drums can be carried under the "minimum" ADR requirements if the carrier chooses to do so. Any packages that meet LQ criteria are not counted.
28. Methanol. This is in transport category 2. The "small load threshold" is 333 litres. Any combination of packages up to that amount can be carried under "minimum" ADR requirements if the carrier chooses to do so. Because methanol has all packages count towards this threshold.
29. Clinical waste (UN 3291). This is in transport category 2 and there is no LQ provision. Thus all packages have to be counted. It is now possible to use combination packaging consisting of an outer "flat pack" corrugated fibreboard box into which is placed a conventional clinical waste bag. Providing the outer box is properly certified this makes the carriage of small amounts of clinical waste possible as “packages”. Sharps containers may also come into this category. Typical situations would be the collection of waste from GPs' surgeries or patients' homes. In these cases, as long as the total load is less than 333 kg (which would normally be the case) the small load exemptions will apply. . Bulk carriage of clinical waste (typical yellow bags loosely loaded into a vehicle) cannot be carried under the small load provisions. Other information concerning clinical waste is in this manual at Clinical waste
30. It can be seen that depending on the substances and the package size, there will be differences in the way the regulations are applied. In each case, if there are mixed loads the aggregation rules in ADR at 18.104.22.168.4 must be applied.

31. Regulation 16 provides that the main parts of the regulations do not apply where carriage is “not undertaken by a vehicle”. This links to the directive’s definition of vehicle and the practical outcome is that the regulations do not apply to:
Vehicles with fewer than four wheels
Vehicles with fewer than four wheels were previously exempted from ADR under the definition of a vehicle in the Dangerous Goods Directive. However, motorcycles are increasingly used to carry dangerous goods in GB, especially for time-critical consignments such as diagnostic specimens where the speed of delivery is vital for the diagnosis and ultimately the treatment of patients. In order to ensure that such consignments continue to be safely transported, GB has decided to extend the scope of the regulations to include motorcycles.
32. Movement wholly within an enclosed area is exempt from the main parts of the regulations. See Regulation 15.
33. MoD vehicles will operate in line with ADR but tankers will be placarded and plated to ADR practice rather then GB practice. Vehicles operated by commercial carriers on contract to MoD or simply delivering to MoD premises are treated conventionally. The Secretary of State for Defence may issue authorisations to allow MoD vehicles to work outside ADR but this will arise only in special cases (see regulation 12).
34. For small loads (ADR 18.104.22.168) there is no need in GB to carry the documentation except for explosives and radioactive materials.
35. The need for the consignor to provide documentation to the carrier remains (ADR 22.214.171.124.1(b) and Regulation 5.
Retail distribution of LQ packages and combination packages (See also the relevant entry: Are there any exemptions from the regulations for retails distribution of goods?
36. A UK derogation (set out in “Dangerous Goods: Approved Derogations and Transitional Provisions”) makes changes to transport categories and load thresholds for many explosives. In effect these changes maintain older arrangements for domestic transport only. See also amended table of transport categories
37. A UK derogation provides that, except for explosives and radioactive materials, the regulations do not apply to the following movements
38. There are related, but more restrictive exemptions for classes 1 and 7 goods. For details see “Dangerous Goods: Approved Derogations and Transitional Provisions”.
39. For a variety of reasons it has been found necessary to issue authorisations to allow certain activities to take place outside the strict scope of ADR. These are added to and deleted as the need arises or recedes. They are all time limited (though in some cases the time is substantial). The up-to-date list may be found at authorisations.
40. The authorisations are all in pdf files and can readily be downloaded. Some are somewhat esoteric, but those most likely to be encountered are:
