Safety questions on the practical test: complete reference with answers

The safety questions on the practical test are short but important. You demonstrate a basic safety check, understand the consequences of faults, and use correct procedures. This article summarises the questions and what to show or answer.

For an introduction to the test itself, see Practical test – complete guide.

What the examiner looks for

  • Systematic execution and calm working method
  • Correct use of the car’s functions and instruments
  • Understanding of consequences of faults and deviations
  • Ability to explain what you do and why

A sequence that works

One simple order that covers the most typical items:

  1. Outside the car: lights, tyres, number‑plate light
  2. Inside the car: seat, mirrors, seatbelt
  3. Lights and signals: dipped beam, main beam, hazard lights, fog lights
  4. Brakes: brake lights, brake booster, brake fluid
  5. Steering and stability: power steering, directional stability

Questions and what to show

QuestionWhat to show/do
Max permitted trailer total weight for this carShow the registration document
Consequences of towing too heavy a trailerLess front‑axle grip, reduced stability, longer braking, headlight glare from raised front
Payload this car can carry in addition to occupantsShow the registration document
Disadvantages of too heavy load in the carWorse handling, longer braking, headlight glare if the front lifts
Trailer total weight allowed with B licenceShow registration document or regulations
Consequences of trailer with too high permitted weightIllegal; less grip, less stability, longer braking, glare from weight on towbar
Check tyres and rims for damageVisual check; look for anything unusual
Most common tyre/rim damageSidewall cuts, rim dents, sidewall bulges
Check wear on both front tyresVisual: is wear even across the tread?
What uneven wear can meanLow pressure: wear on shoulders; high pressure: centre wear; one‑sided wear: misalignment
Check tread depth on both rear tyresVisual or depth gauge; summer ≥ 1.6 mm, winter ≥ 3.0 mm
Risk with too low tread depthPoor grip, higher aquaplaning risk
Find the reflective vestAccessible from the driver’s seat
Place the warning triangleClearly visible. Outside urban areas: 100–200 m before the car, adapt inside urban areas
Correct front‑tyre pressureOwner’s manual or labels (fuel flap/door jamb)
Check pressure in front tyresVisual for even wear, or gauge; some tyres require higher pressure than listed
Check that front tyres have enough treadVisual, depth gauge or wear markers
Tread‑depth requirementsWinter ≥ 3.0 mm; Summer ≥ 1.6 mm
Correct tyre dimensionCheck registration document
Check that front tyres have correct dimensionVisual check
Minimum load index for tyresCheck registration; read marking
Check that rear tyres have correct load indexVisual; read the tyre
Check that all brake lights workUse reflections or ask the examiner to help

Test‑day tips

  • Say briefly what you are doing as you work
  • Use the handbook or registration document when appropriate
  • Be systematic, avoid jumping around
  • If unsure, start with something you know well
