Tyres and grip
Banden en grip
Understand tread, pressure, damage and how weather or load changes the grip available for steering and braking.
Rule
What does Vehicle Knowledge really test?
Vehicle Knowledge is less about becoming a mechanic and more about knowing whether a car is ready, safe and legal to use. You should understand the controls available to the driver, recognise important dashboard warnings and know which checks belong before a journey.
The category connects technical details to decisions. A tyre is not just a component: its condition affects grip, braking and stability. A warning lamp is not just a symbol: it tells you whether you can continue, should stop safely or need expert help.
Exam questions often present a photograph or a short situation. Your job is to identify the safety-critical detail, separate it from irrelevant information and choose the action that reduces risk.
Before departure
Set the car, view and load while stationary.
Amber warning
Understand the fault and arrange timely attention.
Red warning
Prioritise a controlled safe stop and investigate.
Guidance
What you need to understand
Dashboard warnings
Waarschuwingslampjes
Distinguish routine indicators from warnings that require you to stop safely or arrange inspection.
Visibility
Zicht
Keep glass, mirrors, lights and wipers usable so you can see clearly and other road users can see your intentions.
Safety systems
Veiligheidssystemen
Know the purpose of seat belts, head restraints, airbags, ABS and driver-assistance systems without treating them as a substitute for attention.
Loads and passengers
Lading en passagiers
Secure people and objects, protect the driver's view and account for the effect of extra weight on handling and braking.
Controls and preparation
Bediening en voorbereiding
Adjust the seat, steering wheel and mirrors before moving, and locate essential controls before you need them under pressure.
Guidance
Use this five-point pre-drive scan
- 1
Walk around
Look for obvious tyre damage, fluid beneath the car, broken lamps and anything blocking the vehicle.
- 2
Set your position
Adjust seat, head restraint, steering wheel and mirrors before starting the journey.
- 3
Read the dashboard
Check that warning lights behave normally and respond to any warning before entering traffic.
- 4
Secure the cabin
Fasten belts, secure children and loads, and keep windows and mirrors clear.
- 5
Test what matters
Confirm brakes, steering, lights and wipers respond as expected while it is still safe to stop.
The exam usually rewards the safest usable sequence: inspect, prepare, secure, test, then drive.
Vocabulary
Important Dutch terms
Bandenspanning
Tyre pressure
Use the vehicle manufacturer's recommended pressure for the load.
Profieldiepte
Tread depth
Tread helps water escape and preserves grip.
Waarschuwingslampje
Warning light
Colour and symbol indicate urgency and the system involved.
Hoofdsteun
Head restraint
Correct height helps reduce neck injury in a collision.
Remweg
Braking distance
Vehicle condition, speed, road surface and load all matter.
Lading
Load or cargo
Must not shift, obstruct vision or create danger.
Warning
Common mistakes learners make
Treating a warning light as decoration
Why it's wrong: A safety-critical warning can mean the car should not continue until the cause is understood.
Checking mirrors after moving
Why it's wrong: Set your view before joining traffic; adjusting while driving divides attention.
Assuming driver assistance will rescue every mistake
Why it's wrong: Electronic systems support the driver but cannot create grip or replace observation.
Leaving loose objects in the cabin
Why it's wrong: An unsecured object can interfere with controls or become dangerous during sudden braking.
Scenario
Work through the situation step by step
Scenario 01
A tyre looks soft before departure
During your walk-around, one tyre appears lower than the others.
- What to inspect first
- Look for visible damage and compare pressure safely before setting off.
- Correct action
- Correct the pressure or arrange help; do not begin a fast journey while unsure of the tyre's condition.
- Why
- Incorrect pressure can affect grip, stability, fuel use and tyre temperature.
Exam takeaway: A pre-drive warning is easier and safer to solve before entering traffic.
Scenario 02
A red warning appears while driving
A red dashboard warning remains illuminated after the car has started.
- What to inspect first
- Identify the symbol and find a safe place to stop without making an abrupt manoeuvre.
- Correct action
- Stop safely and follow the vehicle guidance or obtain assistance.
- Why
- Red warnings commonly indicate an urgent condition, but the immediate priority remains a controlled safe stop.
Exam takeaway: Respond to urgency without creating a second hazard.
Scenario 03
Luggage blocks the rear view
A tall bag has been placed behind the rear seats and obscures the inside mirror.
- What to inspect first
- Check whether the load can move and whether all required views remain usable.
- Correct action
- Repack and secure the luggage before departure.
- Why
- A clear view and secure load support observation and prevent injury under braking.
Exam takeaway: Prepare the vehicle before the journey, not while moving.
