Q1. What does the ADR agreement primarily govern?

A. The international carriage of dangerous goods by road across Europe
B. The international carriage of dangerous goods by rail
C. The storage of dangerous goods in fixed warehouses
D. The classification of dangerous goods for sea transport only

Show answer & explanation

✓ Answer: A. The international carriage of dangerous goods by road across Europe

ADR stands for the European Agreement concerning the International Carriage of Dangerous Goods by Road. It sets out classification, packing, labelling, documentation and vehicle requirements for road transport, not rail, sea or fixed storage, which are covered by separate regimes (RID, IMDG, COSHH).

Q2. A single package is marked with packing group letter 'Y' as part of its UN specification code. What does this indicate?

A. The package is suitable for goods of packing groups II and III only
B. The package is suitable for packing group I only
C. The package may only be used for liquids, never solids
D. The package has failed drop testing and needs re-certification

Show answer & explanation

✓ Answer: A. The package is suitable for goods of packing groups II and III only

UN packing group letters X, Y and Z indicate performance level: X = suitable for I, II and III; Y = suitable for II and III; Z = suitable for III only. The letter does not restrict the package to liquids or solids, and its presence confirms a pass, not a fail.

Q3. For a small tank of capacity not exceeding 3000 litres, what reduced plate size may be used instead of the standard plate?

A. 200mm x 100mm, with digits at least 50mm high
B. 350mm x 200mm, with digits at least 80mm high
C. 300mm x 120mm, with digits at least 65mm high
D. There is no permitted reduction; all tanks use the standard 40cm x 30cm plate

Show answer & explanation

✓ Answer: C. 300mm x 120mm, with digits at least 65mm high

ADR allows a reduced plate of 300mm x 120mm on small tanks, battery vehicles or MEMUs where the individual element does not exceed 3000 litres, provided the digits are at least 65mm high with a 10mm stroke and visibility is not compromised. This exception does not apply to standard-capacity tanks.
