Fail because of 7 minors?

Emily,

You are allowed upto 15 minors on your driving test. However if you have 3 or more minor driving faults in the same category, this is considered a fail as well. For example, if the driving examiner marked you down 3 times for bad clutch control, then you will not pass but you won't know that until the end of the test. Your driving test will only end if your driving examiner thinks that carrying on with your test is going to be a risk for yourself and other people.

Have you had a chance to look at the marking sheet for your driving test? If not, then it will be a good idea to check it and see which driving faults you have committed and whether they were in the same category or not.
