One serious or dangerous fault ends your test. Here are the most common ones and how to avoid them.
A serious or dangerous fault means an immediate fail — regardless of how well you've driven for the rest of the test. Serious means a fault that could have caused danger in the circumstances. Dangerous means actual danger occurred and the examiner had to take action.
Examples of serious faults: Not checking mirrors before signalling or changing position when another vehicle was present. Not giving way at a junction when another vehicle had to slow. Emerging from a junction without adequate observation. Stalling on a hill and rolling back. Not stopping at a stop line. Going the wrong way on a one-way street. The examiner records these on the DL25 form and explains them in the post-test debrief.
