Norway ADR Exam common mistakes

Norway ADR Exam · Understand the traps and how to avoid them.

Mistake 1

Treating the ADR certificate and the Norwegian driving-licence goods-transport competence as one and the same, so the candidate assumes no additional national requirement exists and cannot state what the ADR certificate actually entitles the holder to do.

The Agreement sets out the ADR driver training and examination requirements, but Norwegian national rules layer additional competence and licence requirements on top. Candidates who study only the ADR text never separate the two layers and blur them under exam pressure.

What to do instead

Build a two-column note: left column = what ADR requires (basic training, specialisation for tanks or Class 7, refresher within 5 years, certificate carried on the vehicle), right column = what Norwegian rules add (goods-transport competence, licence categories, national transport-manager rules). Learn where each fact comes from.

Mistake 2

Answering scope questions by assuming 'dangerous goods' means only goods with a UN number, so the candidate wrongly excludes articles, empty uncleaned packagings, and equipment containing residues from the scope of the Agreement.

The UN number is the most visible identifier on a label or document, so candidates anchor on it. The Agreement's scope is defined by the classes and by the dangerous-goods lists, and empty uncleaned means of containment are explicitly within scope for many provisions.

What to do instead

Memorise the scope logic in order: is the substance or article covered by a class in Part 2? Is it named or covered by a generic or N.O.S. entry? Is it in a special provision or exemption? Then apply the exemption thresholds. Practise on empty uncleaned tank and packaging examples until they become automatic.

Mistake 3

Reading only the proper shipping name in the dangerous goods list and ignoring the columns for special provisions, packing group, limited and excepted quantity limits, and the tunnel restriction code, then giving a plausible but wrong combined answer.

The list is wide and candidates under time pressure scan horizontally for the name and stop. Each column carries a separate rule that often decides the exam question, especially tunnel codes and quantity limits.

What to do instead

Practise reading the list as a fixed sequence of columns for one entry at a time: UN number, name, class, packing group, special provisions, limited quantities, excepted quantities, packing instruction, portable tank instruction, tank code, tunnel code. Recite the sequence aloud until it is a habit before answering.

Mistake 4

Selecting a packing instruction by matching the substance name to a familiar packaging type, instead of looking up the packing instruction referenced in the list and then applying its specific requirements and any special packing provisions.

Candidates remember 'this class usually goes in steel drums' from training examples and generalise. The list assigns the instruction, and the instruction assigns the packaging, not the other way round.

What to do instead

For every packaging question, write down three things before choosing: the packing instruction number from the list, the packing group, and the special packing provisions lettered after the instruction. Only then read the packaging code. Reject any option that skips one of the three.

Mistake 5

Confusing package marking with package labelling, for example stating that the UN number must appear on the orange hazard label, or that the proper shipping name goes on the label rather than beside it.

Both appear on the same package surface and both are often orange or coloured, so they merge visually in memory. Candidates who learned from photographs rather than from the text never separated the two sets of requirements.

What to do instead

Learn the pair as a contrast: marking = UN number and proper shipping name (plus the relevant special marks), applied to the package; labelling = the hazard labels for each hazard, plus elevated-temperature or environmentally hazardous marks where required. Draw one package and place each element yourself.

Mistake 6

Writing a transport document that omits the tunnel restriction code, or placing it in the wrong position, or treating the instructions in writing as a substitute for the transport document.

Candidates memorise the first few document elements (UN number, name, class, packing group) and stop. The tunnel code is a later element and is easily forgotten; the instructions in writing are a separate document with a separate purpose.

What to do instead

Memorise the transport document as an ordered checklist ending with the tunnel restriction code where required, and keep a separate mental slot for the instructions in writing as a cab document in the required language. Practise writing a complete document from a substance entry with nothing left out.

Mistake 7

Describing vehicle marking as 'orange plates front and back' without stating when plates are required, what the numbers on them mean, and when the alternative placarding applies instead.

Orange plates are the most recognisable ADR image, so candidates recall the picture but not the conditions. The distinction between the plain plate and the plate carrying the hazard identification number and UN number is a frequent trap.

What to do instead

Learn three facts together: when orange plates are required for a laden vehicle, what the upper and lower numbers on a plate mean, and when placards or the alternative marking may be used. Then check whether the question is about a tank vehicle, a package vehicle, or a vehicle carrying only limited quantities.

Mistake 8

Applying segregation rules by class alone, for example 'Class 3 and Class 5.1 must always be separated', without checking the specific substances, the segregation groups, and whether the rule concerns mixed loading in one vehicle or separation within a load space.

Class-level rules are the ones taught first and are easier to remember, but the Agreement's segregation provisions operate through segregation groups and specific entries, and the answer depends on which of the two questions is being asked.

What to do instead

Before answering a segregation question, identify the segregation group of each substance from the list, then apply the segregation table, then check whether the question is about mixed loading or about stowage distance. State the group letters in your working, not just the classes.

Mistake 9

Treating the tunnel restriction code as a property of the vehicle or of the driver, rather than of the load, and therefore failing to match the code on the transport document against the category of the tunnel being entered.

Tunnel rules are taught as a driving restriction, so candidates file them with driver behaviour. In fact the code comes from the goods and the decision depends on the tunnel category, which is a separate piece of information.

What to do instead

Learn the decision as a chain: goods entry gives the tunnel code, the code plus the total quantity gives the permitted tunnel categories, the tunnel signage gives the category of the tunnel ahead. Practise the chain on several codes until each step is explicit.

Mistake 10

Answering emergency and incident questions with general first-aid common sense, without linking the response to the instructions in writing, the emergency information, and the duty to inform the emergency services with the specific details required.

First aid and incident response feel like general knowledge, so candidates do not study them as a rule set. The exam expects the specific content of the instructions in writing and the specific information to be passed to the emergency services.

What to do instead

Learn the structure of the instructions in writing as a sequence of actions, and learn the incident notification as a checklist: what happened, where, the substance and its UN number, the quantity, and any injuries or fire. Rehearse both aloud in the order they appear.
