Quick summary
If you’re asking how many mistakes can you make on a driving test UK, the official pass mark is simple: you can pass with up to 15 driving faults (often called “minors”) as long as you make no serious or dangerous faults (often called “majors”).
The catch is that repeating the same minor can turn it into a serious fault, so it’s not just about counting – it’s about staying safe and consistent. This guide shows what counts as a “mistake”, what usually causes fails, and how to cut faults quickly.
How many mistakes can you make on a driving test UK?
The official pass mark for the car driving test (Great Britain)
For the car practical driving test in England, Scotland and Wales, GOV.UK explains you’ll pass if you make 15 or fewer driving faults and no serious or dangerous faults (see driving test faults and your result). In other words:
0–15 driving faults (minors): still pass if there are no serious/dangerous faults
16 driving faults: fail
1 serious fault: fail
1 dangerous fault: fail
That’s the clean answer to “how many mistakes”.
Why “mistakes” isn’t just a number
Learners usually lump everything into “mistakes”, but examiners don’t. They’re judging risk and consistency:
Some mistakes are small and get logged as a minor.
Some mistakes are risky enough to be serious/dangerous.
Some small mistakes become serious if you keep doing them.
That’s why two people can make what feels like the same mistake and get different outcomes – because the risk level changes depending on traffic, speed, and timing.
The 3 types of driving test faults explained (in plain English)
Driving fault (minor): “Not ideal, but not dangerous right now”
A driving fault is a mistake that wasn’t potentially dangerous in that moment. Think: a slightly late mirror check when there’s nobody around, or a bit of hesitation that doesn’t affect anyone.
You’re allowed up to 15, but aiming for “just scrape under 15” is a stressful way to live – because minors can stack up fast when nerves kick in.
Serious fault: “That had the potential to cause danger”
A serious fault means your driving created a situation where it could have become dangerous. Examples often include poor judgement at junctions or roundabouts, not reacting properly to lights/signs/road markings, or moving off when it wasn’t safe.
One serious fault is an automatic fail, even if the rest of your drive was good.
Dangerous fault: “That caused actual danger”
A dangerous fault is when there was actual danger to you, the examiner, other road users, or property. This is also an automatic fail.
Dangerous faults often happen when someone else has to take drastic action because of you (for example, they brake sharply or swerve to avoid a collision).
If you want examples in the exact “test language”, the government’s Ready to Pass page on driving test marking, faults and results explains each fault type clearly.
How minors add up (and when they turn into a fail)
You fail at 16 driving faults
This is the rule learners remember best: 15 or fewer minors can still be a pass; 16 is a fail (confirmed in the GOV.UK pass mark on driving test faults and your result). When someone says “I failed on minors,” it’s usually because they hit 16, or because repeated minors tipped into a serious fault.
Repeating the same minor can become a serious fault
GOV.UK also says a driving fault is not potentially dangerous, but if you keep making the same fault, it could become a serious fault (again, see driving test faults and your result). This is why instructors bang on about patterns.
A common example:
One missed mirror check might be a minor.
Repeated missed mirror checks before lane changes/roundabout exits show poor awareness, which can become serious.
For a deeper breakdown (with learner-friendly examples), use our internal guide on common driving test faults (major and minor) explained.
The examiner marks what happened, not what you “meant”
A lot of fails come from “I was going to…” thinking. Examiners can only mark what they see, and what other road users had to do because of your actions.
If your decision caused another road user to slow down sharply, stop, or get put at risk, the fault level jumps quickly – especially at junctions and roundabouts.
The most common mistakes that cause fails (and how to avoid them)
1) Junction observations (especially when emerging)
Observation faults are a huge reason people fail. DVSA’s GOV.UK guide on the top 10 reasons for failing the driving test in Great Britain lists “not making effective observations at junctions” as number one (based on April 2024 to March 2025 data). It also highlights why this matters: ineffective observation was a factor in a large share of reported collisions in 2023.
What it looks like in a test:
looking too late (the car is already rolling into the new road)
not judging the speed of an approaching vehicle
entering a roundabout when a vehicle is approaching from the right
How to reduce it fast:
don’t creep just because you feel pressured – creep because you’re improving your view
finish your observations before you commit
use a calm routine: “look, decide, go” (not “go and hope”)
2) Mirrors when changing direction
Mirrors are another top fail area – especially on roundabouts, lane changes, and when pulling in/pulling out. A simple fix is using a routine you can do under pressure.
If you’re not consistent yet, drill the Mirror Signal Manoeuvre (MSM) routine until it’s automatic. You’re not trying to be robotic—you’re trying to be reliable when nerves make your brain noisy.
3) Moving off safely (including blind spots)
This catches learners out because it can feel like “nothing happened”. But from an examiner’s view, moving off without proper checks is high risk – especially with cyclists, pedestrians, and cars approaching from behind.
Make it boring (boring passes tests):
mirrors
blind spot check when needed
signal if it helps other road users
move off smoothly with full control
4) Response to signs, road markings and traffic lights
These are easy to revise but easy to mess up under pressure. Typical errors include drifting across lanes, using the wrong lane, stopping over lines, or reacting late to lights.
A great practice trick is “commentary driving” on lessons: say what you see (“left only lane”, “30 sign ahead”, “box junction”) so you scan earlier and plan sooner.
5) Control issues: steering, speed and progress
Some learners are overly cautious and collect minors for hesitation or lack of progress. Others rush and create risk.
Examiners want safe, legal, and appropriate. That means:
smooth steering (no snatching or panicked corrections)
a speed that matches the limit and the conditions
not holding up traffic when it’s clearly safe to go
If you want a quick self-check of the “everyday habits” that turn into test faults, run through common mistakes learner drivers should avoid before your next lesson.
6) Reverse parking and manoeuvres (observations matter most)
Manoeuvres rarely fail you because you’re not perfectly centred. They fail you when:
you don’t do effective all-round observations
you miss a pedestrian/vehicle hazard
you keep rolling instead of stopping to reassess
If manoeuvres are a weak spot, ask your instructor to practise them with a clear “stop–check–go” rhythm. That’s how you stay safe and calm.
What if you make a mistake during the test?
Don’t panic – one mistake doesn’t always mean a fail
Most learners pick up at least one minor. The bigger danger is what happens next: you spiral, rush, and stack faults.
A simple recovery script:
“Ok, that happened.”
“What’s the safe next action?”
“Back to basics: mirrors, speed, space.”
Examiner intervention and “ETA”
GOV.UK explains that if the examiner had to tell you to do something or take control of the car to avoid an incident, your result will show “examiner took action (ETA)” (see understanding your driving test result). Treat ETA as a serious sign that something safety-critical happened and make it a priority practice topic with your instructor.
If you fail, you’ll need to rebook (and there’s a timing rule)
If you do not pass, you have to book another test and pay again – and GOV.UK states you must choose a new date at least 10 working days away (see driving test faults and your result).
If you’re hunting for an earlier slot, it’s worth understanding how cancellations work and how to avoid dodgy offers. Our guide to fast pass driving tests and cancellations covers the legit options and common traps.
How to cut your mistakes before test day (the value-for-time plan)
Do 3 mock tests, but make them “fault focused”
Mocks work best when they turn into a plan:
Mock 1: identify your top 3 fault areas
Mock 2: practise those faults under pressure
Mock 3: check consistency (can you pass on an average day?)
You’ll get the best results when your instructor explains why each issue would be logged as a minor vs serious vs dangerous.
Build routines so nerves can’t steal the basics
A lot of test mistakes are routine failures, not “lack of talent”. Lock in:
a junction routine (mirrors, speed, gear, observations, decision)
MSM for any change in direction/speed/lane
If you’re still figuring out how often to have lessons so routines stick faster, see how many driving lessons you should take each week for realistic schedules.
Don’t throw away an easy mark: ‘show me, tell me’
GOV.UK explains you’ll get one driving fault if you get one or both vehicle safety questions wrong – and you can still fail if your driving becomes dangerous while answering the “show me” question (see the official car ‘show me, tell me’ questions). Learn these the same way you revise theory: little and often.
If theory revision is slowing you down overall, follow a simple routine in how to prepare for your theory test.
Learn with the right support
If you’re paying for lessons, make sure you’re taught by someone properly qualified – here’s what that means in what is an approved driving instructor (ADI). And if you want to compare local options quickly, start with driving instructors near me.
A quick reality check on pass rates
If your nerves are telling you “everyone passes first time,” that’s not real life. The government’s Ready to Pass campaign states that 50 out of every 100 driving tests in Great Britain were failed in January 2026 (see driving test marking, faults and results).
Most fails are down to one or two repeat patterns – not because someone is “bad at driving”. Fix the pattern, and you massively improve your odds.

FAQ's
Yes. For the car practical test in Great Britain, you can pass with 15 driving faults as long as you have no serious or dangerous faults. It’s still worth aiming for fewer, because repeat minors can tip into a serious fault.
Yes. If you get 16 driving faults, you fail – even if none of them were serious or dangerous. If you’re close to that line in mocks, it’s usually a sign you need more consistency, not more “new topics”.
Yes. A single serious fault fails the test because it means your driving had the potential to be dangerous. Many “serious” faults come from judgement at junctions, roundabouts, and response to signs/signals.
A serious fault is something that could have been dangerous, depending on circumstances. A dangerous fault is when there was actual danger to you, the examiner, other road users, or property. Both are fails.
They can. A minor can become a serious fault if you keep repeating the same issue, because it shows a pattern of unsafe or unreliable driving. This is why routines like the MSM routine matter – routines reduce repeat faults.
Yes – getting one or both wrong results in one driving fault. However, if your driving becomes unsafe while answering the “show me” question, that can be treated much more seriously. Practising the list alongside what to expect on the day of your driving test helps you stay calm and prepared.
ETA means “examiner took action”. It’s used when the examiner had to tell you to do something or take control to avoid an incident, which is a strong sign something safety-critical happened. If you see ETA, use it as a clear focus for your next lessons.
You can. Small hesitation might be a minor, but hesitation that creates risk (for example, pulling out too late, confusing others, or causing someone to brake) can be marked as serious. The key is being decisive when it’s safe, not rushing.
You don’t need to announce it, and apologising repeatedly can make you more nervous. It’s better to recover calmly, focus on safe driving, and avoid stacking more faults. If you want help fixing repeat mistakes, start with common mistakes learner drivers should avoid.
For the GB car test, you must choose a new date at least 10 working days away. In reality, availability can be the bigger problem, so it’s smart to stay test-ready and understand cancellations – see fast pass driving tests and cancellations if you’re trying to avoid long waits.
