Understand the mistakes that can affect your practical driving test, what examiners look for and how to prepare with greater confidence. Clear guidance for UK learner drivers, supported by official DVSA information.
Written for JNDS Online by John Nicholson
Your examiner records faults throughout the test. There are three types, and they are not equal: one counts toward a limit, the other two do not.
Not potentially dangerous, but if you keep making the same fault, it could become a serious fault.
Something potentially dangerous.
Involves actual danger to you, the examiner, the public or property.
To pass, you can make no more than 15 driving faults and no serious or dangerous faults. Read the wording on GOV.UK: driving test faults and your result.
These are common areas of difficulty, not a ranked top ten. For the official, current breakdown, see the DVSA driving test failure reasons data.
Pulling out after a quick glance, without taking in what is actually coming.
Other road users may have to brake or swerve.
Practise stopping short and looking, then deciding. Ask your instructor to watch your timing.
Checking late, or not acting on what the mirror shows.
Traffic behind you may be closer or faster than you think.
Build a habit of mirrors, then signal, then manoeuvre, using judgement each time.
Stalling, poor control, or not checking all around first.
Cyclists and passing traffic can be easy to miss.
Practise on hills, bends and behind parked cars, not just on quiet roads.
Drifting, straddling lanes or positioning poorly for turns.
Unclear positioning confuses other drivers.
Review road markings and plan your position early.
Reacting late to traffic lights, or misreading markings.
Late reactions leave less room for error.
Look well ahead and name hazards as you approach them.
Jerky steering, or poor control at low speed and when braking.
Control faults can build up and affect safety.
Work on smooth clutch, brake and steering with your instructor.
The same type of mistake can have different consequences depending on the situation. Understanding the difference can help you focus on safer driving rather than simply memorising a list of faults.
A learner approaches a junction and looks both ways too briefly to take in the road properly. The road happens to be clear, nobody has to react, and no one is put at risk.
The observation was weak, but it did not create a potentially dangerous situation. If the same habit keeps repeating, it could become a serious fault.
A learner decides a gap is big enough and pulls out. An approaching driver has to brake firmly to avoid them. Nothing is hit, but the decision was unsafe.
The decision was potentially dangerous. A serious fault is something potentially dangerous, even where no collision follows.
A learner pulls out without seeing a vehicle that has the right of way, and the other driver must take sudden, emergency avoiding action.
The learner's action created actual danger to another road user. A dangerous fault involves actual danger to you, the examiner, the public or property.
These scenarios are illustrations only. The examiner decides how any real mistake is recorded, based on the circumstances. See the official guidance: GOV.UK: driving test faults and your result.
Effective observation means looking, understanding what you see and acting on it. Turning your head alone does not show that you have.
Common errors include checking mirrors too late, signalling without first looking, or not responding to what you saw. Use mirrors to understand what is behind and beside you, then decide.
Keep a position that suits the road, the turn and the traffic. Stay aware of pedestrians, cyclists and vehicles around you. A routine helps, but it is no substitute for judgement. Your instructor can tailor this to you.
Keep driving safely and follow the examiner's directions. One mistake, however it felt, does not tell you the result: you cannot know how the examiner has recorded it, and a distracted mind makes the next mistake likelier. Settle your breathing, reset and focus on the next hazard.
No set number of lessons guarantees a pass. Everyone needs a different amount of practice.
Ask for honest feedback and target those areas first.
Vary roads, times and conditions, with a qualified instructor or suitable supervising driver.
Review the current Highway Code.
Practise following signs or a sat nav confidently.
Revisit the fault types and examples above, and read the GOV.UK test overview.
Know your documents, your test centre and your route options.

The day before your test is not about learning everything again. It's about arriving prepared, understanding what to expect and giving yourself the best chance to drive safely and confidently.
Confirm your appointment, test centre and travel arrangements. GOV.UK says you must take your UK driving licence, your theory test pass certificate if you have it, and a car. Your test will be cancelled, with no refund, if you don't take the right things. See what to take to your test.
Allow enough travel time, have your documents and car ready, and avoid unnecessary last-minute pressure. Follow any arrival instructions in your booking confirmation.
Follow the test centre's arrival instructions and listen carefully to the examiner. Ask for clarification if you are unsure about an instruction. The test has four parts: an eyesight check, 'show me, tell me' questions, general driving including independent driving, and a reversing exercise.
Focus on safe decisions, effective observation and responding to road conditions. If you think you have made a mistake, keep driving safely and concentrate on what happens next. GOV.UK says a mistake might not affect your result if it is not serious.
