  2. The boot is empty and your vehicle is clear of all valuables and personal belongings.

  4. Wheel hubcaps are removed (only in the case where wheel nuts are not visible) and the tyres are inflated to the correct pressure.
  5. The engine is in a fit state to be tested e.g.Cam belt/Timing belt. You may be asked to sign a disclaimer at the test centre.
  6. All seat belts and clips are fully visible (including rear).
