Understanding how many minors can you have in a driving test is one of the most common questions UK learners ask before stepping into the examiner's seat. The official DVSA answer is simple but strict: you are permitted up to 15 driving faults, often called minors, during your practical driving test. Hit 16 or more, and you fail automatically, regardless of how confident the rest of your drive felt. Knowing this threshold helps you manage nerves, pace your drive, and avoid small slips compounding into a fail.
The UK driving test fault system is split into three clear categories: driving faults (minors), serious faults (majors), and dangerous faults. Only the first category allows you any margin for error. A single serious or dangerous fault ends your hopes of passing on the day, so understanding what each category looks like in practice matters enormously. Examiners assess every observation, signal, mirror check and manoeuvre against the DVSA marking sheet known as the DL25.
For most candidates, racking up minors happens through repetition of the same small habit. For example, forgetting your blind spot check before pulling away, drifting slightly in your lane on a roundabout, or hesitating excessively at a junction. The DVSA does not penalise one-off mistakes harshly, but if you make the same fault three or four times, the examiner can upgrade it to a serious fault on the basis that it shows a pattern of poor habit rather than an isolated lapse.
The good news is that minors are not lurking around every corner waiting to catch you out. The 2024-2025 DVSA pass-rate data shows that the average successful candidate finishes their test with between three and seven minors, well below the 15 limit. Many candidates pass with zero minors, especially after sustained preparation with a qualified instructor and plenty of mock tests. Failing on minors alone is uncommon, accounting for fewer than 8% of failures nationwide.
This guide breaks down every aspect of the UK driving test fault system: what counts as a minor, how serious and dangerous faults differ, the most common reasons people fail, and the practical techniques you can use to stay below the 15-fault threshold.

Whether you are sitting your test next week or just starting lessons, treat this article as your reference for the marking rules examiners use every working day. The clearer you are on how faults are recorded, the calmer your test-day drive will feel. Anxiety often comes from uncertainty, so once you know exactly where the line sits, you can drive with intention rather than fear.
By the end, you will know not just the headline 15-minor limit, but also the patterns examiners watch for, the manoeuvres that trip people up most often, and the recovery techniques that turn a wobble into a non-event rather than a fault. Let's start with the numbers behind the test.
A small mistake that doesn't pose a danger. Examples include a missed mirror check, slight hesitation, or stalling once. You can have up to 15 of these and still pass.
A mistake that could potentially cause danger to you, other road users, or property. Just one of these ends your test immediately. Examples include cutting a corner or missing a stop sign.
Action that involves actual danger to you, the examiner, the public, or property. The examiner may intervene verbally or physically. One dangerous fault is an instant fail.
If you commit the same minor fault three or more times, the examiner can mark it as a serious fault. This is why pattern faults are so important to address during lessons.
So what actually counts as a minor on the DL25 marking sheet? The DVSA assesses 27 different categories of driving behaviour, ranging from precautions before starting the engine through to use of speed, signals, mirrors, judgement at junctions, positioning, and the controlled manoeuvres. Within each category, the examiner can record a tick for a driving fault, an S for serious, or a D for dangerous. The category headings give you a useful checklist of every skill the examiner is watching during your 40 minutes behind the wheel.
Mirror use is one of the highest-frequency areas for minors. Examiners want to see Mirror-Signal-Manoeuvre on every change of direction or speed: pulling away, approaching junctions, changing lanes, overtaking parked cars, and slowing for hazards. Forgetting your right-door mirror before moving off, or skipping an interior mirror check before braking sharply, will likely earn a tick. The fault is not catastrophic on its own, but it is the single most common reason candidates accumulate multiple marks across one drive.
Observation and awareness faults follow closely behind. These include failing to check blind spots before moving off, not scanning effectively at roundabouts, or missing pedestrians stepping into zebra crossings. A minor observation fault usually means you looked but did not act on what you saw, or you simply failed to look at all in a situation where the risk was low. If the risk had been higher, the same lapse would have been recorded as serious instead. Pair this guide with our theory test book recommendations for deeper hazard awareness.
Control faults form the third major bucket. This covers stalling the car, riding the clutch, jerky braking, not maintaining a steady speed, or lurching forward when releasing the handbrake. One stall on a busy junction can be a minor if traffic is held up briefly. Stalling repeatedly, or at a point where you cause real obstruction or risk, escalates the same fault into serious territory. The principle examiners apply is whether your action affected anyone else's safety or progress.
Positioning minors are subtle and frequently surprise candidates after their test. These include driving slightly too close to the kerb, straddling lane markings on dual carriageways, taking the wrong lane at a roundabout exit, or sitting too far from the kerb during a parking manoeuvre. None of these feels dramatic at the time, which is exactly why they slip through. Examiners give you a margin, but consistent positioning errors will add up quickly across a 40-minute route.
Hesitation versus undue caution is a tricky area where many candidates pick up unexpected minors. If you wait too long at a clear junction, the examiner will record a fault for undue hesitation. Conversely, pulling out into a gap that's too tight risks a serious fault for poor judgement. The skill lies in reading traffic decisively, committing to your gap, and avoiding the freeze-and-creep behaviour that wastes opportunities and frustrates following drivers.
Finally, signalling faults are easier to avoid than most. The two big ones are signalling unnecessarily (which can mislead other drivers) and forgetting to cancel a signal after a manoeuvre. Modern cars with self-cancelling indicators reduce the second problem, but you should still glance down to confirm the indicator has dropped. Signal-related minors are essentially a free win: with a few seconds of mental rehearsal, they should never appear on your DL25.
Observation faults are the leading cause of minors recorded on the DL25 sheet. The most common is failing to check the right-side blind spot before moving away from the kerb, especially after a hill-start or parking manoeuvre. Examiners want to see your head turn, not just a glance at the mirror. A clear shoulder check is unmissable and demonstrates you have considered cyclists and motorcycles approaching from behind.
Less obvious observation minors include failing to scan roundabouts as you approach, not rechecking pedestrians at zebra crossings before moving off, and missing approaching traffic from a side road when you have priority but visibility is restricted. Build the habit in lessons of speaking your observations out loud. The examiner will not hear them on test day, but the mental routine will be embedded by then and observations become automatic.
Control minors centre on smooth use of the clutch, brake, accelerator, and steering. The most common is stalling, particularly on hill starts or when pulling away in second gear. One isolated stall in a quiet location is usually marked as a single minor, but stalling at a busy junction, or stalling three times across the test, will escalate the fault. Keep clutch control crisp by practising the bite point until it feels instinctive.
Steering control faults include over-steering, under-steering on bends, crossing your hands at the wheel during slow manoeuvres, or letting the wheel spin back unchecked. Modern DVSA guidance accepts a relaxed grip and natural hand-over-hand movement, but losing contact with the wheel entirely is a fault. Smooth braking, no harsh acceleration, and progressive gear changes also fall under this category.
Positioning faults often catch candidates by surprise because they feel natural during the drive. Common minors include driving too close to parked cars, straddling lane lines on dual carriageways, drifting wide on left-hand bends, and entering the wrong lane at a roundabout exit. The examiner expects you to maintain a consistent road position, normally about a metre from the kerb on standard urban roads.
During manoeuvres, positioning errors are equally common. Finishing a parallel park more than 30 centimetres from the kerb, ending a bay park outside the marked lines, or stopping a forward bay park at an angle all count as minors. Use reference points your instructor teaches you, and practise the same manoeuvre in different car parks until your finishing position is consistent regardless of the surroundings.
Examiners are trained to spot patterns. If you skip your right-side mirror check three times during the test, what was originally three minors can be reclassified as one serious fault on the basis that it demonstrates a habit rather than a slip. Address pattern faults during your final lessons, not weaknesses you only do once.
Serious and dangerous faults are entirely different beasts from minors, and understanding the dividing line is essential. A serious fault is recorded when your action could potentially cause danger, even if no actual danger occurred. The classic examples include emerging from a junction without proper observation, drifting into oncoming traffic, ignoring a stop line, or failing to spot a red traffic light until the last moment. The examiner does not need to intervene for a fault to be serious; the potential for harm is enough.
Dangerous faults occur when actual danger materialises, normally requiring the examiner to take verbal or physical action. Examples include the examiner grabbing the wheel, applying the dual brake, or shouting a warning to prevent a collision. Driving onto the wrong side of the road, accelerating towards a pedestrian, or reversing into another car all qualify. Dangerous faults are rare because they require a genuine safety threat, but their consequence is identical to a serious fault: an immediate fail with no possibility of recovery.
The most common serious faults nationally, according to DVSA data, are junctions (observation), use of mirrors when changing direction, control during steering, response to signs and signals, and positioning during normal driving. Three of these five overlap directly with the top minor-fault categories, which tells you something important: minors and serious faults share root causes. The difference is the level of risk created in that specific moment.
Take roundabouts as an example. Approaching too fast and slightly straddling a lane line might be marked as a minor for positioning. But if your speed forces another driver to brake hard, or you cut across the inside lane forcing them to swerve, the same fundamental error is now a serious fault. The behaviour is identical; the context determines the marking. This is why examiners drive routes they know intimately, with predictable traffic patterns that reveal candidate judgement.
Pedal confusion is another serious-fault flashpoint. Pressing the accelerator when intending to brake is treated as dangerous regardless of outcome, because it represents a fundamental loss of vehicle control. The fact that nothing happened is purely luck, not skill. Examiners record dangerous immediately and end the test if the situation warrants it. Practise the brake-pedal-only approach to stopping in lessons until your foot finds the brake without conscious thought.
Failing to obey traffic signs accounts for around 9% of all serious faults. The classic mistakes are missing a 30 mph speed-limit change, ignoring a no-entry sign on a one-way street, or driving past a school sign at full national speed limit. These are non-negotiable: examiners cannot mark them as anything other than serious because they represent a direct breach of the Highway Code. Build a habit of reading every sign aloud during lessons.
Finally, examiner intervention almost always upgrades a fault. If the examiner uses the dual controls, says something to alter your course, or has to brace visibly, the fault is automatically serious or dangerous. The presence of intervention proves the risk was real. Drive on the assumption that the examiner is hoping not to need to intervene, and your margin for error widens accordingly.
Now that you know how many minors can you have in a driving test, the focus shifts to staying well below that limit. The most successful candidates aim for zero minors, knowing that aiming for 14 leaves no buffer when nerves create unexpected slips. Treat every observation, signal, and manoeuvre as if it were the only one being marked, and the cumulative effect over 40 minutes will keep your DL25 sheet largely clean. The DVSA does not reward perfection, but it does notice consistency.
Mock tests are the single most effective preparation tool. Ask your instructor to conduct three or four full mock tests in the two weeks before your real test, including the show-me-tell-me questions, the independent driving section, and at least one manoeuvre per session. Have them mark you exactly as a DVSA examiner would, using a real DL25 form. The first mock often produces 8-12 minors and a serious or two; by the third or fourth, candidates routinely drop to two or three minors with no serious faults.
Drive the test centre area in the weeks leading up to your booking. Examiners use a finite set of routes, and although you cannot memorise them all, familiarity with the local roundabouts, tricky junctions, school zones, and 20 mph areas reduces cognitive load significantly. Less mental effort spent decoding the environment means more attention available for mirror checks, signals, and observations. Many driving schools publish guides to test-centre routes for exactly this reason. Compare timings with our theory test duration guide to plan your overall preparation calendar.
Sleep, hydration, and breakfast matter more than most candidates appreciate. A tired brain reacts a fraction of a second slower, which is exactly the margin that turns a routine observation into a missed one. Eat a balanced breakfast at least 90 minutes before your test, avoid excessive caffeine which can amplify nerves, and arrive at the test centre 15 minutes early to settle in without rush. These small physiological investments pay disproportionate dividends.
Manage your nerves with a pre-test routine you have rehearsed. Many instructors recommend a 30-minute warm-up drive on quiet local roads, ending at the test centre car park with time to spare. The warm-up clears any rustiness, lets you check mirrors and seating position, and gives you a confidence boost when the examiner approaches. Do not change your driving style on test day; drive exactly as you have in lessons, and trust the muscle memory you have built.
Listen carefully to examiner instructions. Most are given in plain English with plenty of time to act, but candidates under stress sometimes mishear directions or anticipate the wrong turn. If you are unsure, ask the examiner to repeat. There is no fault for clarifying, and there is a serious fault potentially waiting if you turn the wrong way into oncoming traffic. The examiner wants you to pass; they are not playing tricks.
Finally, accept that one minor is not the end of the world. If you stall, miss a mirror, or hesitate, take a deep breath and refocus. The fault is recorded, but the rest of the test still counts. Candidates who panic after a single mistake often compound it into three or four more minors in the next 60 seconds, which is exactly how a pass becomes a fail. Compartmentalise each fault and keep driving as if it never happened.
Practical tips for the final week before your test can transform a borderline candidate into a confident pass. Start by reviewing your DL25 sheets from recent mock tests. Identify the categories where minors clustered, and dedicate at least one full lesson per problem area. If mirror use is your weak spot, ask your instructor to commentate loudly on every mirror moment in real time. The auditory reinforcement embeds the habit far faster than silent repetition.
Refresh your show-me-tell-me knowledge thoroughly. While these questions only generate a single minor if answered wrong, getting them right starts the test on a positive note and lifts confidence going into the first minute of driving. The DVSA publishes the complete question bank online, with 14 tell-me questions asked at the start and 7 show-me questions asked during the drive. Memorise all 21, then practise saying the answers out loud as if explaining to a passenger.
On test day itself, arrive with all required documents: your provisional licence, your theory test certificate, and confirmation of your booking. Forgetting any of these means automatic cancellation with no refund. Wear comfortable shoes with thin soles for accurate pedal feel. Heavy boots or chunky trainers can cause unintended acceleration or braking, and high heels make clutch control much harder than necessary.
During the test, narrate quietly to yourself. Mental commentary such as mirror, signal, brake, gear, observe keeps your brain on the procedural checklist rather than dwelling on nerves. Examiners do not penalise visible concentration or muted self-talk; what they reward is consistent execution of the procedures you were taught. Speak to yourself if it helps you stay on rhythm, and treat the examiner as a benign passenger rather than a judge waiting to fail you.
If you make a mistake, acknowledge it briefly to yourself and move on. A useful technique is the three-second rule: give yourself three seconds to register the error, then deliberately refocus on the next instruction. Dwelling on a missed mirror check for 30 seconds while approaching a roundabout is what creates the second, third, and fourth minor in quick succession. The examiner only marks what happens; they cannot read your internal regret.
Manoeuvres deserve special attention because they are predictable and rehearsable. The DVSA tests one of four: parallel park, bay park (forward or reverse), pulling up on the right and reversing, or an emergency stop. Each has reference points your instructor has drilled into you. Use them. There is no bonus for completing a manoeuvre quickly; examiners value control and accuracy. Take your time, pause to look around mid-manoeuvre, and use the gear lever fluidly to switch between forward and reverse.
Finally, treat the independent driving section like normal driving with a sat-nav passenger. The 20-minute section is designed to assess your ability to follow signs or sat-nav instructions while maintaining everything else. If you miss a turn, do not panic; the examiner will simply give you a new instruction. Missed turns are not faults in themselves, only the manner in which you respond is assessed. Calm, controlled driving wins the day. For full booking and logistics details, see our book driving test guide.
