The most common question learners ask before their practical test is simple: how many faults are you allowed before you fail? The answer is more nuanced than a single number, because not all faults are equal. This guide explains the three types of fault the examiner records, exactly how many minor faults you're allowed, the most common ones learners pick up, and how to keep your fault count low on test day.
The Three Types of Driving Test Fault
On the practical test, the examiner records faults in three categories:
Dangerous fault. A fault that involves actual danger to you, the examiner, the public or property. A single dangerous fault means you fail.
Serious fault. A fault that is potentially dangerous, even if no harm actually resulted. A single serious fault also means you fail.
Driving fault (minor). A fault that isn't dangerous in itself, but that would become serious if you kept repeating it. Minor faults are the ones you're allowed a certain number of.
The examiner assesses every fault based on how serious it was and the conditions at the time. Your goal is straightforward: avoid all dangerous and serious faults, and keep your minor faults to a minimum.
How Many Minor Faults Are You Allowed?
You can accumulate up to 15 minor (driving) faults and still pass. Get 16 or more, and you fail, even without a single serious or dangerous fault.
Fifteen sounds generous, but it's wise to keep your count well below it, for one important reason: a minor fault you keep repeating can be upgraded to a serious fault.
The Truth About Repeated Minor Faults
You may have heard that "three of the same minor becomes a serious fault." That's a common myth, and it's not quite how it works. There's no fixed three-strikes rule. What's actually true is that if you repeatedly make the same driving fault, showing it's a persistent habit rather than a one-off, the examiner can judge that pattern to be a serious fault, which fails you.
So the principle behind the myth is real, even if the exact "three" isn't: consistency of a fault matters. One missed mirror check is a minor; missing your mirrors again and again suggests a genuine safety weakness, and that's what can tip into a serious fault. The lesson is the same either way, don't let any single fault become a pattern.
The Most Common Minor Faults
Most minor faults come from a handful of recurring situations. The most common include:
Not pressing the clutch fully when starting the engine, so the car lurches if it's left in gear. Failing to apply the handbrake when coming to a complete stop. Not making the proper observations when moving off or stopping, this is a minor, but an unsafe move-off can quickly become a serious fault. Bringing the clutch and footbrake down together during the emergency stop. Finishing a reversing manoeuvre at an awkward angle to the kerb, or too far from it. Not using your mirrors and observations during a reversing manoeuvre to check for pedestrians. Failing to use the right controls when conditions change, such as switching on your lights in poor visibility. And, most commonly of all, not using your mirrors and observations consistently to stay aware of other road users, signs and markings.
Notice how many of these come back to observation and mirror use. If you take one thing away, make your mirror checks second nature, it's the single biggest source of avoidable minors.
What Happens at the End of the Test
Throughout the test, the examiner quietly records your faults. Try not to dwell on this while you're driving, worrying about a fault you think you've made only distracts you from the road ahead. Focus on driving safely and confidently, one moment at a time.
At the end, the examiner tells you whether you've passed or failed, then talks you through your faults and how each one occurred. You're given a copy of your Driving Test Report, an exact record of every fault. If you didn't pass, that report is genuinely valuable: it tells you precisely what to work on before your next attempt.
Summary:
The practical test records three types of fault: dangerous and serious faults each fail you instantly, while minor (driving) faults are allowed up to a limit of 15. Sixteen or more minors means a fail, and repeating the same minor can see it upgraded to a serious fault, so keeping your count low matters. Most minors come down to observation and mirror use, so building those habits until they're automatic is the surest way to pass. And whatever the result, your Driving Test Report shows you exactly where to improve.
Frequently Asked Questions
How many minor faults are you allowed on the driving test?
You're allowed up to 15 minor (driving) faults and can still pass. Reaching 16 or more means you fail, as does a single serious or dangerous fault regardless of your minor count.
Do three of the same minor fault equal a serious fault?
Not automatically. There's no fixed three-strikes rule. However, if you repeatedly make the same fault so that it's clearly a persistent habit, the examiner can judge that pattern to be a serious fault, which would fail you. The safest approach is not to let any fault become a repeated one.
What's the difference between a minor, serious and dangerous fault?
A minor (driving) fault isn't dangerous in itself but could become serious if repeated. A serious fault is potentially dangerous, and a dangerous fault involves actual danger. A single serious or dangerous fault means you fail, while minors are allowed up to 15.
What are the most common minor faults?
The most common involve observation and mirror use, such as not checking mirrors before moving off, signalling or changing direction. Others include not applying the handbrake at a stop, poor positioning on reversing manoeuvres, and not using the right controls when conditions change.
Will I be told my faults at the end of the test?
Yes. The examiner tells you whether you passed or failed, explains the faults you picked up and how they occurred, and gives you a copy of your Driving Test Report. If you didn't pass, this report is a precise guide to what to work on before your next attempt.
