If the car fails

What defects A, B and C mean, how long you may drive the car and what happens if you drive an unroadworthy vehicle.

What do defects A, B and C mean?

A is a minor defect – the car passes and you just fix it. B is a major defect – the car is temporarily roadworthy, you may drive it for 30 days and must go for a repeat inspection. C is a dangerous defect – the car is not roadworthy and the inspection sticker is removed.

How long can I drive with a major defect?

With a major defect (B) you may drive for 30 days. If you come for the repeat inspection within that time, only the defects found are checked; after 30 days the car needs a full inspection again.
