7D VAN PRACTICE TEST: COMPREHENSIVE EXAMINATION FOR LARGE GOODS
VEHICLE OPERATORS
SECTION A: VEHICLE FAMILIARISATION AND PRE-OPERATIONAL CHECKS (Questions
1-40)
1. What is the minimum tyre tread depth legally required for a 7D van in most
jurisdictions?
A) 1.0mm
B) 1.6mm
C) 2.0mm
D) 2.5mm
Answer: B) 1.6mm
Rationale: The legal minimum tread depth for commercial vehicles including 7D
vans is 1.6mm across the central three-quarters of the tyre circumference. This
ensures adequate grip and water displacement for safe operation.
2. Before commencing a journey in a 7D van, what should be the first pre-operational
check?
A) Check fuel level
B) Check tyre pressures
C) Walk-around inspection
D) Check mirrors adjustment
Answer: C) Walk-around inspection
Rationale: A thorough walk-around inspection allows the driver to identify any
visible defects, obstructions, or potential hazards before entering the vehicle. This
includes checking for fluid leaks, tyre condition, and overall vehicle integrity.
3. What is the maximum authorised mass (MAM) typically associated with a 7D van
category?
A) Up to 3.5 tonnes
B) Up to 7.5 tonnes
C) Between 3.5 and 7.5 tonnes
D) Over 7.5 tonnes
Answer: C) Between 3.5 and 7.5 tonnes
Rationale: 7D vans typically fall within the 3.5 to 7.5 tonnes weight category,
requiring specific licensing and operating considerations distinct from smaller vans
or larger HGVs.
,4. When checking engine oil level, when should this be performed for most accurate
reading?
A) Immediately after switching off the engine
B) When engine is cold and on level ground
C) While engine is running
D) After 30 minutes of driving
Answer: B) When engine is cold and on level ground
Rationale: Checking oil when cold ensures all oil has drained to the sump, providing
an accurate level reading. A level surface prevents false readings due to oil pooling.
5. What does a flashing amber warning light on a 7D van dashboard typically indicate?
A) Critical system failure
B) System requires immediate attention
C) Minor system warning
D) Service reminder
Answer: B) System requires immediate attention
Rationale: Flashing amber warnings indicate systems that, while not immediately
critical, require prompt attention to prevent potential failure or safety compromise.
Red indicates immediate danger, while green/blue indicates normal operation.
6. How often should the brake fluid level be checked in a 7D van?
A) Daily
B) Weekly
C) Monthly
D) Before each journey
Answer: A) Daily
Rationale: Brake fluid level should be checked daily as part of pre-use inspection.
Any significant drop may indicate brake pad wear or system leakage requiring
immediate investigation.
7. What is the correct procedure for checking power steering fluid?
A) Check when cold with engine off
B) Check when warm with engine running
C) Check at operating temperature with engine off
D) Check with engine running at idle
Answer: D) Check with engine running at idle
Rationale: Power steering systems operate under pressure; the fluid level should be
checked with the engine running at idle to ensure accurate reading as the system is
pressurised.
,8. What is the purpose of the engine coolant expansion tank?
A) To store extra coolant
B) To allow coolant expansion when hot
C) To mix coolant with water
D) To pressurise the cooling system
Answer: B) To allow coolant expansion when hot
Rationale: As coolant heats and expands, the excess volume moves into the
expansion tank, preventing system over-pressurisation and allowing fluid return
when the system cools.
9. When checking tyre pressures, when should this ideally be performed?
A) When tyres are hot
B) When tyres are cold
C) After 10 miles of driving
D) Immediately after parking
Answer: B) When tyres are cold
Rationale: Tyre pressures should be checked when cold (before driving or after
standing for at least 3 hours) as heat from driving increases pressure and can give
false readings.
10. What does the ABS warning light indicate if it remains illuminated after starting?
A) ABS system is operational
B) ABS system has a fault
C) ABS is temporarily disabled
D) ABS needs servicing soon
Answer: B) ABS system has a fault
Rationale: The ABS warning light should illuminate briefly during system self-test
and then extinguish. If it remains on, there is a fault requiring professional diagnosis.
11. What is the minimum acceptable brake pad thickness for a 7D van?
A) 1.5mm
B) 2.0mm
C) 3.0mm
D) 4.0mm
Answer: C) 3.0mm
Rationale: The minimum legal thickness for brake pads on commercial vehicles is
3.0mm, though manufacturers often recommend replacement at 4.0mm for optimal
performance.
, 12. How should you check for brake fluid contamination?
A) By colour and clarity
B) By smell
C) By taste
D) By temperature
Answer: A) By colour and clarity
Rationale: Brake fluid should be clear, light amber in colour, and free from particles.
Dark, cloudy, or contaminated fluid indicates moisture absorption or system
degradation.
13. What is the correct way to check the operation of service brakes?
A) Press pedal while stationary
B) Test at slow speed
C) Apply brakes firmly while moving forward slowly
D) Use handbrake only
Answer: C) Apply brakes firmly while moving forward slowly
Rationale: Applying brakes firmly at slow speed allows testing of brake
effectiveness, feeling for any pulling, pulsation, or unusual noises while maintaining
safety.
14. What does the battery condition indicator show?
A) State of charge
B) Voltage level
C) Both state of charge and condition
D) Age of battery
Answer: C) Both state of charge and condition
Rationale: Modern batteries include condition indicators showing charge level and
overall health through colour-coded displays (green = good, dark = needs charge,
yellow = replace).
15. What is the purpose of the diesel particulate filter (DPF)?
A) To improve fuel efficiency
B) To reduce exhaust emissions
C) To increase engine power
D) To reduce engine noise
Answer: B) To reduce exhaust emissions
Rationale: The DPF captures and stores soot particles from exhaust gases, reducing
particulate emissions. Regular regeneration burns off accumulated soot.
