Here are the theory test questions for A09 Forward Tipping Dumper.
During the theory test you'll be asked a maximum of 40 questions.
Please note that your paper will include all the questions we have marked here with an asterisk *. In addition you will have a random selection of the other questions that are not marked here with an asterisk.
These questions will appear on every A09 paper

The function or job role of a dumper driver, when transporting materials, is to? (2 marks)*
If setting up to work in a pedestrianised area, state THREE factors that need to be taken into account. (3 marks)*
a) What is the minimum distance allowed near open trenches when travelling with a dumper and
b) explain why? (2 marks)*

What allows the wheels to follow the contours of the ground when travelling on uneven ground? (2 marks)
The operator has to use a new type of dumper, i.e. swivel skip that they are unfamiliar with.
What do Regulations (i.e. PUWER 98) and other guidance require the operator to have? (3 marks)
Before leaving the dumper for a rest break, after parking and switching off the engine,
a) what final action must be carried out and
b) why? (2 marks)
What may happen if the load is tipped onto a downward slope? (2 marks)
Give FOUR reasons that may cause the dumper to tip over sideways during travel. (4 marks)
A dumper is classified by a manufacturer as a six-tonne dumper.
What does this mean? (1 marks)
Name THREE problems that could occur if the skip is overloaded with a dense/ compacted material. (3 marks)
What is a possible consequence of using a tyre with a deep cut in the sidewall? (1 marks)
Operators should lower the skip fully before driving away, particularly on swivel skips. Give TWO possible consequences if this is not carried out. (4 marks)
Larger dumpers use a turbo-charged engine.
a) What is the normal procedure before switching off the engine after working and
b) what happens if the procedure is not followed? (2 marks)
In what situation does a hard hat NOT need to be worn when operating a forward tipping dumper? (2 marks)
When travelling on wet clay, what effect does this have on the dumper? (2 marks)
Who should determine the maximum load that should be placed into the skip of the dumper? (1 marks)
If the operator has to top-up the hydraulic oil, state TWO precautions to ensure cleanliness of the system. (2 marks)
When parking the machine at the end of the shift, name THREE places where the dumper should NOT be parked. (3 marks)
Why do high tip dumpers need particular care when tipping? (2 marks)
When working in a confined area or space what danger can be present with an articulated dumper with regards to steering? (1 marks)
Give TWO reasons for using a swivel skip dumper over a conventional forward tipping skip. (2 marks)
