Question 1General requirements and legal framework (ADR, national rules, driver obligations, liability)

Under ADR, which document must a driver of a vehicle carrying dangerous goods generally be able to present during a roadside check?

  1. The consignee's commercial invoice
  2. The vehicle's annual roadworthiness certificate only
  3. The manufacturer's safety data sheet
  4. The transport document for the goods being carried Correct answer.

Explanation

ADR requires that the transport document describing the dangerous goods accompanies every consignment and is available for inspection by the competent authorities. It identifies the goods by UN number, proper shipping name, class, packing group and quantity. Other papers may exist, but the transport document is the core ADR document for the journey.

Question 2General requirements and legal framework (ADR, national rules, driver obligations, liability)

What is the primary purpose of the ADR Agreement?

  1. To regulate customs duties on chemical products
  2. To set maximum vehicle weights for road freight
  3. To standardise driver working hours across Europe
  4. To harmonise conditions for the international carriage of dangerous goods by road Correct answer.

Explanation

ADR is the European Agreement concerning the International Carriage of Dangerous Goods by Road. Its purpose is to increase safety by harmonising the conditions under which dangerous goods move internationally by road, covering classification, packaging, documentation, vehicle equipment and driver training. It does not set general traffic, customs or social rules.

Question 3General requirements and legal framework (ADR, national rules, driver obligations, liability)

A driver holds a valid ADR vocational training certificate for tank vehicles. What does this authorise in addition to tank carriage?

  1. Carriage of dangerous goods in bulk containers of any class
  2. Carriage of radioactive material exclusively
  3. Carriage of packaged dangerous goods in all classes Correct answer.
  4. Carriage of only class 3 flammable liquids

Explanation

The ADR driver training certificate for tank vehicles covers carriage in tanks and also covers carriage of dangerous goods in packages for all classes, because the tank extension builds on the full basic course. A driver with only a tank endorsement still holds the underlying package entitlement. Separate class-specific endorsements apply only to explosives and radioactive material.

Question 4General requirements and legal framework (ADR, national rules, driver obligations, liability)

Which classes require a specific additional endorsement on the ADR driver certificate beyond the basic course?

  1. Class 1 and class 7 Correct answer.
  2. Class 2 and class 3
  3. Class 4 and class 5
  4. Class 8 and class 9

Explanation

ADR requires separate specialist training for class 1 explosives and class 7 radioactive material, in addition to the basic course. The basic certificate covers the other classes for packaged goods. Tank carriage is a separate extension rather than a class-specific endorsement.

Question 5General requirements and legal framework (ADR, national rules, driver obligations, liability)

How long is an ADR driver training certificate normally valid before it must be renewed?

  1. Two years
  2. Five years Correct answer.
  3. Ten years
  4. Three years

Explanation

An ADR driver training certificate is issued for a period of five years and must be renewed through refresher training before expiry. The renewal ensures drivers keep up to date with changes to the regulations. Carrying an expired certificate is equivalent to having no valid certificate.

Question 6General requirements and legal framework (ADR, national rules, driver obligations, liability)

A driver is stopped and cannot produce a valid ADR training certificate while carrying dangerous goods. What is the typical legal consequence?

  1. The journey may be prohibited and the driver exposed to penalties under national law Correct answer.
  2. The goods are automatically confiscated by the police
  3. The vehicle is permanently withdrawn from service
  4. The consignor must take over the driving duties

Explanation

Carrying dangerous goods without a valid ADR certificate is an offence under national law implementing ADR, and enforcement officers can stop the journey until compliance is achieved. Penalties may include fines and immobilisation of the vehicle. Permanent confiscation of goods or vehicles is not the standard response.

Question 7General requirements and legal framework (ADR, national rules, driver obligations, liability)

Who is responsible for ensuring that the driver has received the required ADR training before a journey begins?

  1. The driver's family
  2. The employer or operator engaging the driver Correct answer.
  3. The vehicle manufacturer
  4. The road toll operator

Explanation

ADR places duties on the participants in the transport chain, and the employer or operator must ensure the driver is properly trained and certificated before assigning the journey. The driver also has a personal duty to hold and carry the certificate. Manufacturers and toll operators have no role in driver training.

Question 8General requirements and legal framework (ADR, national rules, driver obligations, liability)

Which of the following is a general obligation of the driver under ADR while the vehicle is in motion or parked?

  1. Removing hazard labels at each stop
  2. Supervising the vehicle so that unauthorised persons cannot access the dangerous goods Correct answer.
  3. Leaving the vehicle unlocked at rest areas
  4. Allowing any passer-by to inspect the load

Explanation

ADR requires the driver to supervise the vehicle or otherwise ensure it is secure so that unauthorised persons cannot gain access to the dangerous goods. This includes attention during parking and rest stops. The driver must not leave the load accessible or remove required markings during the journey.

Question 9General requirements and legal framework (ADR, national rules, driver obligations, liability)

What should a driver do first if a package carrying dangerous goods begins to leak during transport?

  1. Throw the leaking package onto the roadside
  2. Increase speed to reach a workshop quickly
  3. Stop in a safe place and follow the written instructions and emergency procedures Correct answer.
  4. Continue to the destination to save time

Explanation

The driver should stop as soon as it is safe, keep away from ignition sources and populated areas where appropriate, and consult the written instructions carried on the vehicle. These instructions describe the emergency actions for the specific goods. Continuing the journey or abandoning the package increases risk.

Question 10General requirements and legal framework (ADR, national rules, driver obligations, liability)

What information must the ADR transport document contain for a consignment of dangerous goods?

  1. Only the driver's certificate number
  2. Only the vehicle registration number
  3. Only the consignee's name and address
  4. UN number, proper shipping name, class, packing group and total quantity Correct answer.

Explanation

The transport document must identify the goods by UN number, proper shipping name, hazard class and, where assigned, packing group, together with the total quantity and number of packages. Additional entries such as tunnel restriction codes may be required. Identification of the goods is the central function of the document.

Question 11General requirements and legal framework (ADR, national rules, driver obligations, liability)

A driver is carrying a load for which the ADR tunnel restriction code prohibits passage through a certain tunnel category. What must the driver do?

  1. Enter the tunnel at reduced speed
  2. Ask another driver to lead the way through
  3. Switch off the engine and coast through
  4. Avoid that tunnel and use a route permitted for the load Correct answer.

Explanation

Tunnel restriction codes indicate which tunnel categories a load may not pass through, and the driver must plan a route that avoids prohibited tunnels. Speed reduction or escort does not remove the restriction. National authorities may sign diversion routes for such loads.

Question 12General requirements and legal framework (ADR, national rules, driver obligations, liability)

What is the role of the ADR safety adviser in a transport undertaking?

  1. Driving the vehicle when the regular driver is ill
  2. Advising on compliance with dangerous goods rules and preparing safety reports Correct answer.
  3. Issuing the driver training certificate
  4. Inspecting only the vehicle's tyres

Explanation

The safety adviser helps the undertaking comply with dangerous goods regulations, monitors practices and prepares the required annual report on the undertaking's dangerous goods activities. The role is advisory and monitoring, not operational driving. Certificates are issued by competent authorities after training and examination.

Question 13General requirements and legal framework (ADR, national rules, driver obligations, liability)

Which statement best describes the driver's duty regarding the written instructions (tremcard) in the cab?

  1. They must be kept readily available in the cab for use in an emergency Correct answer.
  2. They may be left at the depot for safekeeping
  3. They are only needed for tank vehicles
  4. They can be replaced by a verbal briefing

Explanation

ADR requires written instructions to be carried in the cab and readily accessible so the driver can act immediately in an emergency. They describe the nature of the danger and the actions to take. A verbal briefing or storage at the depot does not satisfy the requirement.

Question 14General requirements and legal framework (ADR, national rules, driver obligations, liability)

A driver is asked to carry a load whose packages are not properly labelled and marked. What is the appropriate action?

  1. Load the packages and label them at the destination
  2. Refuse to load or proceed until the marking and labelling are corrected Correct answer.
  3. Cover the unmarked packages with a tarpaulin and drive
  4. Accept the load if the transport document is complete

Explanation

Packages must be marked and labelled in accordance with ADR before carriage, and the driver should not accept a non-compliant load. Missing markings prevent emergency responders and others from identifying the hazard. Corrective action by the consignor is needed before the journey continues.

Question 15General requirements and legal framework (ADR, national rules, driver obligations, liability)

What is the general rule on smoking and open flames in the vicinity of a vehicle carrying dangerous goods?

  1. Smoking is allowed if the windows are closed
  2. Smoking is permitted if the driver stays near the cab
  3. Smoking and open flames are prohibited during loading, unloading and carriage Correct answer.
  4. Smoking is allowed only at night

Explanation

ADR prohibits smoking and the use of open flames in the vicinity of vehicles carrying dangerous goods, particularly during loading and unloading and when the goods are flammable. The prohibition protects against ignition of vapours. It applies regardless of time of day or proximity to the cab.

Question 16General requirements and legal framework (ADR, national rules, driver obligations, liability)

A vehicle carrying dangerous goods is involved in a collision. Which sequence best reflects the driver's priorities?

  1. Leave the scene to find a telephone
  2. Photograph the scene before doing anything else
  3. Move the goods to another vehicle before calling anyone
  4. Make the scene safe, warn traffic, give first aid and notify the emergency services Correct answer.

Explanation

The driver should first secure the scene and warn other traffic, then attend to injured persons and alert the emergency services, informing them of the dangerous goods involved. Evidence gathering comes after safety and notification. Leaving the scene without taking these steps is not acceptable.

Question 17General requirements and legal framework (ADR, national rules, driver obligations, liability)

Which of the following best explains why ADR requires the driver to check that the vehicle is not overloaded and that the load is properly secured?

  1. It is required only for class 9 goods
  2. It allows the driver to skip the pre-trip walkaround check
  3. It reduces the amount of toll payable on the route
  4. Poor load security and overloading increase the risk of spillage and instability in carriage Correct answer.

Explanation

Unsecured loads can shift, packages can fall and containers can be damaged, which may release dangerous goods. Overloading affects braking and stability. ADR and general road law therefore require proper stowage and respect for permissible masses. The requirement applies across classes, not just class 9.

Question 18General requirements and legal framework (ADR, national rules, driver obligations, liability)

A driver's ADR certificate is due to expire in two weeks and refresher training has not yet been arranged. What is the correct position?

  1. The driver may not carry dangerous goods once the certificate expires until it is renewed Correct answer.
  2. The certificate is automatically renewed on payment of a fee
  3. The certificate remains valid indefinitely if the driver has ten years' experience
  4. The employer can extend the certificate by one year in writing

Explanation

The certificate is valid only for the period stated, and carriage of dangerous goods after expiry is unlawful until the driver completes refresher training and receives a renewed certificate. Experience or administrative extensions do not preserve validity. Only the competent authority issues certificates.

Question 19General requirements and legal framework (ADR, national rules, driver obligations, liability)

In the ADR framework, which participants share responsibility for the safe carriage of dangerous goods?

  1. Only the driver
  2. Only the emergency services
  3. Only the consignor
  4. Consignor, carrier, loader, driver and consignee according to their roles Correct answer.

Explanation

ADR allocates duties to several participants, including the consignor, carrier, loader, unloader, driver and consignee, each according to the stage they control. This shared responsibility means compliance depends on correct classification, packing, documentation and handling at each step. Placing the whole burden on one party would leave gaps.

Question 20General requirements and legal framework (ADR, national rules, driver obligations, liability)

A consignor offers a load whose transport document omits the packing group for a goods where one is assigned. How should the carrier respond?

  1. Query the documentation with the consignor and not proceed until it is complete and correct Correct answer.
  2. Add a packing group chosen at random and continue
  3. Ignore the omission because packing group is optional
  4. Record the omission on a note and complete the journey

Explanation

The transport document must include the packing group where ADR assigns one, so the carrier should raise the deficiency with the consignor and ensure the document is corrected before carriage. Guessing the packing group could mislead responders and breach the rules. Proceeding with an incomplete document is not compliant.

Question 21Classification of dangerous goods, hazard properties and classes

Under the ADR classification system, which class covers flammable liquids?

  1. Class 8
  2. Class 3 Correct answer.
  3. Class 5.1
  4. Class 2

Explanation

Class 3 of the ADR system covers flammable liquids, meaning liquids with a flash point of not more than 60 degrees Celsius, or liquids offered for transport at temperatures at or above their flash point. Class 2 covers gases and Class 8 covers corrosive substances, so those classes cannot apply to a flammable liquid.

Question 22Classification of dangerous goods, hazard properties and classes

A substance is assigned packing group I. What does this indicate?

  1. Medium danger
  2. Low danger
  3. No danger at all
  4. High danger Correct answer.

Explanation

Packing groups express the degree of danger within a class: packing group I means high danger, II means medium danger and III means low danger. The assignment follows the criteria in Part 2 of ADR for the relevant class, such as flash point and boiling point for Class 3.

Question 23Classification of dangerous goods, hazard properties and classes

Which class contains organic peroxides?

  1. Class 3
  2. Class 6.1
  3. Class 5.2 Correct answer.
  4. Class 4.1

Explanation

Organic peroxides are assigned to Class 5.2 because they are thermally unstable substances that may undergo exothermic self-accelerating decomposition. Class 4.1 covers flammable solids, Class 3 flammable liquids and Class 6.1 toxic substances, so none of these fits organic peroxides.

Question 24Classification of dangerous goods, hazard properties and classes

What does the hazard identification number 33 on an orange plate indicate?

  1. Very flammable liquid Correct answer.
  2. Toxic gas
  3. Oxidizing substance
  4. Corrosive solid

Explanation

In the hazard identification number, the first digit 3 indicates a flammable liquid and the repeated digit 3 indicates that the substance is very flammable, meaning its flash point is below 23 degrees Celsius. The hazard identification number is read from left to right, with repetition of a digit intensifying the hazard.

Question 25Classification of dangerous goods, hazard properties and classes

Which of the following is a Class 1 dangerous good?

  1. Oxygen
  2. Petrol
  3. Sodium hydroxide
  4. Black powder Correct answer.

Explanation

Class 1 covers explosives, and black powder is a classic explosive substance assigned to this class. Petrol is a flammable liquid of Class 3, sodium hydroxide is a corrosive of Class 8 and oxygen is an oxidizing gas of Class 2.

Question 26Classification of dangerous goods, hazard properties and classes

Which signal word appears on a label for a substance of Class 6.1, packing group I?

  1. Toxic Correct answer.
  2. Flammable
  3. Corrosive
  4. Oxidizing

Explanation

Class 6.1 covers toxic substances, and the label for this class shows a skull and crossbones together with the word Toxic. The other words describe hazards belonging to different classes, such as flammable for Class 3 or corrosive for Class 8.

Question 27Classification of dangerous goods, hazard properties and classes

A liquid has a flash point of 35 degrees Celsius and a boiling point of 90 degrees Celsius. To which packing group does it belong under Class 3 criteria?

  1. It cannot be assigned to Class 3
  2. Packing group III Correct answer.
  3. Packing group I
  4. Packing group II

Explanation

For Class 3, packing group II applies when the flash point is below 23 degrees Celsius, and packing group III applies when the flash point is between 23 and 60 degrees Celsius. With a flash point of 35 degrees Celsius and a boiling point above 35 degrees Celsius, the liquid falls into packing group III.

Question 28Classification of dangerous goods, hazard properties and classes

Which of the following substances is assigned to Class 4.3?

  1. Hydrochloric acid
  2. Calcium carbide Correct answer.
  3. Sulphur
  4. Ammonium nitrate

Explanation

Class 4.3 covers substances which, in contact with water, emit flammable gases, and calcium carbide reacts with water to release acetylene. Sulphur is a flammable solid of Class 4.1, ammonium nitrate is an oxidizer of Class 5.1 and hydrochloric acid is a corrosive of Class 8.

Question 29Classification of dangerous goods, hazard properties and classes

What does the letter X in the first position of a four-digit UN number on an orange plate mean?

  1. The substance is radioactive
  2. The substance is environmentally hazardous
  3. The substance reacts dangerously with water Correct answer.
  4. The substance is a gas under pressure

Explanation

When the hazard identification number is preceded by the letter X, the substance reacts dangerously with water, for example by emitting flammable gas or heat. The letter is placed before the digits so that emergency responders know water must not be used.

Question 30Classification of dangerous goods, hazard properties and classes

A consignment contains a substance of Class 6.1, packing group II. Which statement about its toxicity is correct?

  1. It is toxic only to aquatic life
  2. It is harmful if swallowed, inhaled or in contact with skin Correct answer.
  3. It is only dangerous when heated
  4. It is not toxic but may cause fire

Explanation

Class 6.1 covers substances known to be toxic to humans, and packing group II indicates medium danger, meaning the substance is harmful if swallowed, inhaled or in contact with skin. Toxicity criteria are based on oral, dermal and inhalation exposure limits set out in Part 2 of ADR.

Question 31Classification of dangerous goods, hazard properties and classes

Which statement best describes a Class 2 gas according to ADR?

  1. A solid that ignites easily at room temperature
  2. A liquid that corrodes steel
  3. A substance with a vapour pressure of 300 kPa at 50 degrees Celsius Correct answer.
  4. A liquid with a flash point of 40 degrees Celsius

Explanation

A gas is defined as a substance whose vapour pressure at 50 degrees Celsius is greater than 300 kPa, or which is completely gaseous at 20 degrees Celsius and standard pressure. A liquid with a flash point of 40 degrees Celsius is a Class 3 flammable liquid, not a gas.

Question 32Classification of dangerous goods, hazard properties and classes

Which of the following is an example of a Class 7 dangerous good?

  1. Uranium hexafluoride Correct answer.
  2. Butane
  3. Potassium permanganate
  4. Sulphuric acid

Explanation

Class 7 covers radioactive material, and uranium hexafluoride is a radioactive compound assigned to this class. Sulphuric acid is a corrosive of Class 8, butane is a flammable gas of Class 2 and potassium permanganate is an oxidizer of Class 5.1.

Question 33Classification of dangerous goods, hazard properties and classes

A substance carries the class 5.1 label. What hazard does this indicate?

  1. It may emit flammable gas on contact with water
  2. It may cause severe burns to skin
  3. It may cause or intensify fire by releasing oxygen Correct answer.
  4. It may explode when struck

Explanation

Class 5.1 covers oxidizing substances which, while not necessarily combustible themselves, can yield oxygen and thereby cause or contribute to the combustion of other material. Explosives belong to Class 1, corrosives to Class 8 and water-reactive substances to Class 4.3.

Question 34Classification of dangerous goods, hazard properties and classes

Which criterion determines whether a liquid is assigned to Class 3?

  1. A vapour pressure above 300 kPa at 50 degrees Celsius
  2. A flash point of not more than 60 degrees Celsius Correct answer.
  3. A pH value below 2
  4. A boiling point above 200 degrees Celsius

Explanation

Class 3 comprises liquids with a flash point of not more than 60 degrees Celsius, or liquids transported at or above their flash point. A vapour pressure above 300 kPa at 50 degrees Celsius would instead indicate a gas of Class 2, and a low pH would suggest a corrosive of Class 8.

Question 35Classification of dangerous goods, hazard properties and classes

A substance of Class 8, packing group III, is being classified. Which property is decisive for this class?

  1. It ignites spontaneously in air
  2. It is toxic when inhaled
  3. It is radioactive
  4. It destroys living tissue on contact Correct answer.

Explanation

Class 8 covers substances that cause full-thickness destruction of skin tissue or corrode steel or aluminium, and packing group III indicates low danger within this class. Spontaneous ignition in air is a property of Class 4.2, while toxicity and radioactivity belong to Classes 6.1 and 7.

Question 36Classification of dangerous goods, hazard properties and classes

Which combination correctly matches a class with its hazard?

  1. Class 9 with toxic gases
  2. Class 5.2 with flammable solids
  3. Class 6.2 with oxidizing substances
  4. Class 4.2 with substances liable to spontaneous combustion Correct answer.

Explanation

Class 4.2 covers pyrophoric substances and self-heating substances liable to spontaneous combustion. Class 5.2 covers organic peroxides, Class 6.2 infectious substances and Class 9 miscellaneous dangerous goods, so the other pairings are incorrect.

Question 37Classification of dangerous goods, hazard properties and classes

A substance has a flash point of 18 degrees Celsius and an initial boiling point of 40 degrees Celsius. Which packing group and class apply?

  1. Class 3, packing group III
  2. Class 3, packing group I
  3. Class 3, packing group II Correct answer.
  4. Class 2, packing group I

Explanation

The flash point below 23 degrees Celsius confirms Class 3. Packing group I requires an initial boiling point of not more than 35 degrees Celsius, and because this substance boils at 40 degrees Celsius, packing group II applies instead.

Question 38Classification of dangerous goods, hazard properties and classes

Which statement about the relationship between a class and its divisions is correct?

  1. Class 1 is divided into divisions 1.1 to 1.6 according to the type of explosion hazard Correct answer.
  2. Class 3 is divided into divisions 3.1 to 3.3 according to flash point
  3. Class 2 is divided into divisions 2.1 to 2.6 according to toxicity
  4. Class 8 is divided into divisions 8.1 to 8.3 according to pH

Explanation

Only Class 1 is subdivided into divisions 1.1 to 1.6, which describe the mass explosion hazard, projection hazard and related risks. Classes 2, 3 and 8 use categories or packing groups rather than divisions of this kind.

Question 39Classification of dangerous goods, hazard properties and classes

Two liquids are compared: liquid A has a flash point of 25 degrees Celsius and liquid B has a flash point of 55 degrees Celsius. How are they classified?

  1. Both are Class 3, but A is packing group III and B is also packing group III Correct answer.
  2. Both are Class 3, but A is packing group II and B is packing group III
  3. A is Class 2 and B is Class 3
  4. A is Class 3 and B is not a dangerous good

Explanation

Both liquids have flash points of 60 degrees Celsius or less, so both are Class 3 flammable liquids. Because packing group II requires a flash point below 23 degrees Celsius, neither qualifies, and both fall into packing group III, which covers flash points from 23 to 60 degrees Celsius.

Question 40Classification of dangerous goods, hazard properties and classes

A consignment is described as UN 1203, Class 3, packing group II. What does this tell the driver about the substance?

  1. It is petrol, a flammable liquid of medium danger within Class 3 Correct answer.
  2. It is a toxic gas of high danger
  3. It is a corrosive solid of low danger
  4. It is an oxidizing liquid of medium danger

Explanation

UN 1203 is the entry for petrol, a Class 3 flammable liquid, and packing group II indicates medium danger within that class. The UN number, class and packing group together form the core of the classification that must appear in the transport document.

Question 41Packaging, IBCs, large packagings, tanks and vehicle equipment

Under ADR, what does the orange-coloured plate displayed at the front and rear of a tank vehicle show?

  1. The UN number on top and the hazard identification number below
  2. The total mass of the vehicle and the driver's licence category
  3. The hazard identification number on top and the UN number below Correct answer.
  4. The route code and the date of the next periodic inspection

Explanation

ADR requires tank vehicles to carry orange plates with two numbers: the upper line is the hazard identification number (Kemler code) and the lower line is the UN number of the substance carried. Plain vehicles carrying packaged dangerous goods use plain orange plates without numbers.

Question 42Packaging, IBCs, large packagings, tanks and vehicle equipment

A driver must load UN 1203 petrol in packagings and UN 1263 paint in packagings into the same vehicle. Which document-based check is essential before loading?

  1. Checking that both substances have the same packing group
  2. Checking that the vehicle has a fire extinguisher of at least 12 kg
  3. Checking that the total number of packages does not exceed 100
  4. Checking that the substances are compatible and that segregation requirements in the transport document are met Correct answer.

Explanation

Before loading, the driver must verify that the goods may be loaded together, taking account of the transport document and the segregation rules for dangerous goods of different classes. Packing groups may differ and package counts are not the criterion for mixed loading.

Question 43Packaging, IBCs, large packagings, tanks and vehicle equipment

What is the minimum number of portable fire extinguishers (or equivalent total capacity) required on a vehicle carrying dangerous goods in packages above the small-load threshold?

  1. No extinguisher is required if the vehicle carries fewer than 20 packages
  2. One extinguisher of at least 2 kg suitable for engine and cab fires
  3. Two extinguishers, one for the cab and one for the load, with a total capacity of at least 12 kg Correct answer.
  4. A single extinguisher of at least 6 kg only

Explanation

ADR requires at least two portable extinguishers on the vehicle: one suitable for engine/cab fires and one for the load, with a combined minimum capacity of 12 kg of dry powder (or equivalent). One of them must have a minimum capacity of 6 kg.

Question 44Packaging, IBCs, large packagings, tanks and vehicle equipment

Which statement correctly describes the purpose of an IBC (intermediate bulk container) marking under ADR?

  1. It shows that the container has been approved for air transport only
  2. It records the name of the consignee and the delivery address
  3. It replaces the need for any hazard label on the container
  4. It certifies design type approval, including the UN symbol, packing group and test details Correct answer.

Explanation

The IBC marking includes the UN packaging symbol, the code identifying the IBC type, the packing group(s) authorised, the maximum gross mass and the year of manufacture, together with test information. It is a design-type approval marking, not a substitute for hazard labels.

Question 45Packaging, IBCs, large packagings, tanks and vehicle equipment

A tank container is being loaded with a substance whose tank code in column (12) of the dangerous goods list ends in the letter 'P'. What does this letter indicate?

  1. The tank requires a bottom discharge and cannot be top-filled
  2. The tank shell is made of a specific stainless steel grade
  3. The substance must be carried only in a tank with a lining
  4. The tank is fitted with a pressure-relief device that must be checked before loading Correct answer.

Explanation

In the ADR tank code, letters appended after the numerical part indicate special provisions for the tank, and 'P' denotes a pressure-relief device requirement. The driver/loader should confirm the tank is correctly equipped and that the device is in working order before loading.

Question 46Packaging, IBCs, large packagings, tanks and vehicle equipment

What is the correct action if a driver discovers that a package bearing a corrosive label is damaged and leaking before loading?

  1. Load it only if the vehicle is empty of other goods
  2. Wrap the package in plastic and load it with absorbent material
  3. Load it at the rear of the vehicle and inform the consignee on arrival
  4. Refuse the package and report the damage to the responsible person Correct answer.

Explanation

A leaking or damaged package must not be loaded. The driver should refuse it and report the defect so that the consignor or responsible person can deal with it, protecting both the vehicle and other cargo.

Question 47Packaging, IBCs, large packagings, tanks and vehicle equipment

Which vehicle equipment item is specifically required for a vehicle carrying dangerous goods in packages, in addition to fire extinguishers?

  1. A satellite navigation device and a mobile phone
  2. A wheel chock, an eye-rinsing liquid and a warning vest for each crew member Correct answer.
  3. A spare wheel and a tow rope
  4. A first-aid kit and a fire blanket only

Explanation

ADR lists additional equipment including wheel chocks, a warning vest, and eye-rinsing liquid (or an equivalent eyewash) for each crew member. These items support safe securing and personal protection.

Question 48Packaging, IBCs, large packagings, tanks and vehicle equipment

A driver loads two large packagings side by side. Which securing approach ensures the load cannot move during transport?

  1. Using the vehicle's side walls alone to contain the packagings
  2. Relying on the packagings' own weight to keep them in place
  3. Securing the packagings to the vehicle using suitable restraints such as straps or bars Correct answer.
  4. Placing the packagings against the rear doors only

Explanation

The load must be secured so that it cannot shift, tip or slide; suitable restraints such as lashing straps, bars or blocking must be used. Side walls and rear doors alone do not guarantee immobilisation.

Question 49Packaging, IBCs, large packagings, tanks and vehicle equipment

What information must the transport document contain for dangerous goods carried in IBCs?

  1. The UN number, proper shipping name, class, packing group and the number and type of IBCs Correct answer.
  2. The route and estimated time of arrival
  3. The IBC manufacturer's name and the year of manufacture only
  4. Only the total mass and the consignee's address

Explanation

The transport document must identify the goods by UN number, proper shipping name, hazard class and packing group, and must state the number and description of the packages or IBCs. Manufacturer details and route information are not the required dangerous goods particulars.

Question 50Packaging, IBCs, large packagings, tanks and vehicle equipment

A vehicle carrying a tank is fitted with a speed limitation device. What is the general ADR requirement for the maximum speed of vehicles carrying dangerous goods in tanks?
