Driving test faults: what the different marks mean

To pass the car practical driving test in Great Britain, you need no serious or dangerous faults and no more than 15 driving faults. A serious fault is potentially dangerous; a dangerous fault involves actual danger. An ordinary driving fault is not potentially dangerous, although repetition can make a fault serious. These distinctions come from GOV.UK's test-result guidance.

The familiar words “minor” and “major” can make the assessment sound like a points game. It is more useful to understand what happened, what risk it created and what the examiner recorded. This guide explains the scoring framework; it is not a way to predict an examiner's decision from a brief description of an incident.

The three fault categories

• Driving fault: not potentially dangerous in that situation; no more than 15 in total are permitted for a pass.
• Serious fault: potentially dangerous; none are permitted for a pass.
• Dangerous fault: involves actual danger; none are permitted for a pass.

These are not exchangeable units. Several good manoeuvres do not cancel a serious fault, and a dangerous fault is not simply a larger number of ordinary faults. Equally, noticing that you made a small mistake does not establish that you have failed.

If you finish with 15 driving faults and no serious or dangerous fault, that is within the published threshold. Sixteen driving faults is outside it. This arithmetic explains the limit, but it should not become your driving strategy: you cannot reliably count and grade your own faults while managing traffic.

Why the situation matters

Learners often ask whether a particular action is “always a minor” or “automatically a fail”. A short label rarely includes everything necessary to answer. The examiner can see the road users, timing, visibility and effect of the action, whereas a later description may leave those details out.

Consider a hesitation. The useful discussion is not just how many seconds passed. Ask what you could see, what information was missing and whether your decision showed appropriate planning. Likewise, describing an observation as “a mirror check” does not explain whether you gathered useful information at the point when it mattered.

This is why copying somebody else's reported result can be misleading. Similar-sounding incidents are not necessarily equivalent situations. Use your own examiner feedback and the official descriptions rather than treating a forum anecdote as a marking rule.

Repeated faults are not a fixed allowance

GOV.UK warns that repeatedly making the same driving fault can result in it becoming serious. Its candidate guidance does not provide a universal rule such as “you are allowed three of each”. Do not build preparation around an invented repetition quota.

Repeated errors deserve attention even when their individual marks appear modest. They may reveal an unreliable habit: gathering information late, planning only when a situation becomes urgent, or operating a control without enough familiarity. The learning goal is to make the skill dependable, not to keep its count just below a guessed boundary.

During practice, ask your instructor to distinguish an isolated lapse from a pattern. Then agree how you will demonstrate improvement across different situations, rather than performing one successful repetition and declaring the problem finished.

Read the result categories, not just the total

DVSA's guide to understanding your car-test result explains the assessed areas and gives examples. It also explains “examiner took action”, or ETA: this records an intervention by instruction or control to avoid an incident.

A heading on the result is a starting point for discussion. It does not necessarily tell you everything about where an event occurred or why it received a particular severity. If something is unclear, note your question and discuss the explanation while the test is still fresh in your memory.

For your own learning notes, use four short fields:

• Situation: where the difficulty arose and what was happening.
• Decision or action: what you did, without adding excuses or assumptions.
• Missing skill: what would have helped you respond safely and in time.
• Practice task: how you and your instructor will work on that skill.

A useful practice task might be identifying information earlier on approaches, rather than merely repeating “check more”. Keep it specific enough that you can recognise improvement.

What if you think you made a fault during the test?

Keep your attention on safe driving and the next situation. Mentally replaying the previous junction while approaching another creates a new distraction. Do not attempt a sudden correction simply to hide something you think the examiner noticed.

If an instruction is unclear, ask for clarification. Treat the examiner's assessment as their task and safe observation, planning and control as yours. You will have an opportunity to review the outcome afterwards.

Our test-day checklist covers preparation around the appointment. Removing avoidable problems with documents, arrival and familiar controls leaves more attention available for the drive itself, although no checklist can guarantee a pass.

Use feedback after a pass as well as after a fail

A pass does not make every recorded weakness irrelevant. An ordinary fault can still identify something worth improving before you drive independently in unfamiliar conditions. Ask what further practice would make that area more consistent.

After an unsuccessful attempt, do not reduce the plan to “get fewer minors”. Work out which skill or decision needs attention, including any serious or dangerous fault. A narrowly missed numerical threshold and a low total with a serious fault call for different discussions.

Our existing common driving-test mistakes article focuses on practical errors. Use it alongside your result rather than replacing personalised feedback with a general list.

Northern Ireland's practical-test threshold

Nidirect's car-test guidance also allows up to 15 driving faults, with a serious or dangerous fault resulting in failure. Northern Ireland has its own DVA test process and report guidance, so use those instructions for your appointment and feedback.

Plan the next lesson around evidence

Bring your result and the questions you want to resolve to a lesson discussion. Explore our driving courses or contact Learn and Drive about suitable tuition. The most useful outcome is a clear practice plan based on the decisions behind the marks, not a promise that a certain number of lessons will produce a particular score.
