CPCS TRAFFIC MARSHALLER (A73)
TEST QUESTIONS (SET 2025)
Guaranteed Accurate Answers &
Detailed Explanations
ABOUT THIS STUDY GUIDE
This study guide covers the key knowledge areas for the CPCS Plant
and Vehicle Marshaller (A73) test. It is based on the official CPCS
syllabus, the Construction Plant Competence Scheme technical test
requirements, and the HSE guidance document L64 for safety signals.
The information reflects the 2025/2026 testing format.
SECTION 1: PLANNING & PREPARATION (Questions
1-15)
Question 1
When a marshalling operation for vehicle movements is being
planned, list in the order of importance, the FOUR stages that should
be taken into account.
Correct Answer:
, 1. MINIMISE MOVEMENT AND REVERSING
2. ISOLATE THE AREA
3. CONTROL AN AREA WITHIN A LARGER WORKING AREA
4. CONTROLLING THE VEHICLES THROUGH OTHER WORK AREA
Rationale: The primary goal of any marshalling plan is safety through
minimising risk. The first stage is to minimise the number of
movements and reversing actions required. If this isn't possible, the
next stage is to isolate the area to keep other personnel out. If the
area cannot be fully isolated, then control is established within the
larger area. The final stage is to manage movements through other
work areas when required.
Question 2
What are the advantages of implementing a one-way traffic system?
Correct Answer: Reduces the need for reversing, lower risk of
collisions, improves pedestrian safety.
Rationale: One-way traffic systems make traffic flow predictable,
which is vital for safety on busy construction sites. By reducing the
need for reversing manoeuvres (a high-risk activity), they lower the risk
of collisions and create a safer environment for pedestrians.
Question 3
Name FOUR possible causes where the marshaller's capabilities could
be exceeded.
,Correct Answer:
1. Unexpected situations or sudden changes in the work
environment
2. Changes to the traffic management plan
3. Adverse weather conditions
4. Equipment failure
Rationale: A marshaller's role is to ensure safety, but they can be
overwhelmed if the situation changes beyond their control. New work,
unauthorised movements, plan changes, and poor weather can all
create hazards that exceed a marshaller's ability to manage safely.
Question 4
What is the main responsibility of the plant and vehicle marshaller?
Correct Answer: To ensure the safe movement of the plant or vehicle.
Rationale: The marshaller's primary responsibility is to manage the
movement of vehicles and plant safely, but it is important to
remember that the driver/operator remains ultimately responsible for
the safe operation of their machine.
Question 5
What is the purpose of a logistics or delivery plan?
Correct Answer: To ensure the safe movement and routing of vehicles,
establishing when a delivery is coming and where it will be stored.
, Rationale: A logistics plan provides vital information for coordinating
deliveries, reducing congestion and the potential for accidents by
ensuring that vehicles follow safe and designated routes.
Question 6
What is the purpose of a traffic management plan?
Correct Answer: To ensure a safe, predictable flow of vehicles and
pedestrians through the site.
Rationale: A traffic management plan outlines entry and exit points,
designated site routes, one-way systems, pedestrian walkways, and
holding areas for waiting vehicles. It creates a safe environment by
establishing clear, predictable movement patterns.
Question 7
What is the first stage in planning a marshalling operation?
Correct Answer: Minimise movement and reversing where possible.
Rationale: The most effective way to reduce risk is to minimise the
number of vehicle movements and reversing actions required. If a
vehicle movement can be eliminated or simplified, the risk is reduced
from the outset.
