Driving test faults: how minors, serious and dangerous faults are marked

The three fault levels, and the level below them

Every mistake the examiner notices is measured against what a safe, competent driver would have done in the same spot. The bigger the gap, and the more risk it created at that moment, the higher the level. The examiner guidance also has a fourth level that never appears on your result: a slip too small to record.

A serious fault isn't always about other traffic. Breaking the law, such as going through a red light, ignoring a stop sign or driving well over the speed limit, is marked serious even on an empty road.

How the examiner decides which level to mark

GOV.UK publishes the guidance examiners are trained on, and three questions sit at the heart of it. Knowing them takes much of the mystery out of a result.

• The first rule. If your drive had been flawless before and after this one mistake, would it alone justify a fail? If the answer is yes, it's serious or dangerous.
• The 16th fault test. Before recording a minor at all, the examiner asks whether they could justify failing you if this were your 16th. If not, it isn't worth recording.
• Adding and taking away. Could the mistake have been worse, or better? Brushing the kerb when you pull up is one thing; bumping or mounting it shows a bigger loss of control.

Examiners also wait until a situation has finished before marking it, and they don't mark the same error twice. On a reversing exercise, though, control and observation are assessed separately, so one bay park can earn a mark in each.

How many minors can you get?

Fifteen. A 16th driving fault is a fail even if none of them was serious. In practice the pattern matters more than the total. The guidance says a driving fault committed habitually throughout the test can be judged potentially dangerous and marked serious, and it uses missed mirror checks as the classic case.

There's no fixed number in the published guidance that turns repeated minors into a serious fault. A few separate lapses in one category may stay as minors, while skipping the same check every time you change lanes is the kind of habit that gets upgraded. Treat any category with two or more marks as a priority.

The vehicle safety questions are scored differently. Getting one or both of the 'show me, tell me' questions wrong costs a single driving fault, but losing control of the car while you answer the 'show me' question on the move can fail you.

Where minors tip into serious faults

These comparisons come from the published assessment criteria. Each shows the point at which the same kind of mistake stops being a minor.

• Junction observation: misjudging a gap so another driver slows is a minor; emerging without effective observation into another vehicle's path is serious.
• Gears: a wrong gear that slows you with nobody behind is a minor; one that drops your speed suddenly and forces following traffic to brake or swerve is serious.
• Speed: a short spell too fast for the conditions is a minor; exceeding the limit is serious, and the tolerance over a limit is small.
• Emergency stop (shown as 'controlled stop' on your result): a brief skid you recover from is a minor; braking so harshly that the car keeps skidding out of control is serious.
• Restarting after a stall: trying to start the engine in gear with the handbrake on is a minor; starting in gear so the car lurches into a new road is serious.
• Progress: not going when it's safe is a minor; stopping and waiting when it's clearly safe to proceed can be serious. Our guide to undue hesitation covers this in depth.

What you get at the end of the test

The examiner gives the result once you've parked, explains the faults they marked, and asks whether you want your instructor or accompanying driver to listen. A summary then arrives by email, or by post if you chose that, listing each driving, serious and dangerous fault under its heading.

Two extra items can appear. ETA, 'examiner took action', means they had to give an urgent instruction or use the controls, and it's recorded as verbal or physical. Eco-safe driving is assessed for planning and control, but GOV.UK states it doesn't affect whether you pass.

Examiners aren't allowed to go through the test in more detail than the debrief, so take the summary to your instructor. If the result was a fail, our guide to what to do after a failed driving test covers rebooking rules and appeals.

Turn your fault list into a practice plan

1. Sort by level. Deal with every serious or dangerous fault first, then any category with repeated minors.
2. Match each fault to the Highway Code. GOV.UK's guide to understanding your result links each heading, such as junctions, mirrors or progress, to the rules behind it.
3. Rebuild the situation. Practise the layouts where the faults happened: right turns at roundabouts, emerging from side roads, lane changes on dual carriageways.
4. Rehearse under test conditions. A full mock driving test marked with the same three levels shows whether the fix holds under pressure.
5. Measure rather than guess. SteerClear's mock test scores a drive by fault type, and Mac, the app's AI driving coach, explains what happened and what to work on next.

Practising on the kind of roads near your centre helps as well. Test routes aren't published, so SteerClear offers practice routes around your chosen centre, such as Aberdeen North, with turn-by-turn voice guidance; our driving test routes page explains how that works. SteerClear is an independent app with no connection to GOV.UK or the examiners who mark your test. For the rest of the day itself, start with the practical driving test guide.
