Understanding the common reasons learners fail their driving test can help you prepare more effectively and avoid turning small habits into serious mistakes. The practical test is not about driving perfectly; it is about showing that you can drive safely, make sound decisions and remain in control without help.
According to the Driver and Vehicle Standards Agency (DVSA), the most frequent faults involve observation, mirrors, moving off, positioning, signs, road markings, steering and speed. Here are the key areas to work on before taking your driving test in Loughborough.
How Driving Test Faults Are Marked
There are three types of fault: a driving fault, a serious fault and a dangerous fault. You can pass with no more than 15 driving faults, but one serious or dangerous fault will result in a fail. Repeating the same driving fault can also become serious if it shows an unsafe pattern.
You can read the full GOV.UK explanation of driving test faults and results.
1. Not Making Effective Observations at Junctions
Junction observation is consistently one of the most common reasons for failing. Problems include looking too late, emerging without a clear view, approaching too quickly or failing to check properly in both directions.
How to improve: Approach at a speed that gives you time to assess the junction. Use effective observation rather than a quick glance, and do not proceed until you are confident that the gap is safe. If visibility is restricted, move forward gradually while continuing to look.
2. Not Using Mirrors Correctly
Mirror checks need to happen before you change speed or direction. Common mistakes include signalling before checking, moving lanes without checking for nearby traffic, or leaving the mirror check until the manoeuvre has already begun.
How to improve: Build a consistent mirrors-before-action habit. Check the appropriate mirrors before signalling, changing position, changing lanes, slowing down or pulling up. The examiner needs to see that your observation affects the decision you make.
3. Moving Off Unsafely
Learners can lose marks by moving away without an effective blind-spot check, rolling back on a hill, or pulling out when another road user is approaching.
How to improve: Prepare the car first, make all-round observations, check the relevant blind spot and move only when it is safe. Take extra care when moving away from behind a parked vehicle because your view may be restricted.
4. Incorrect Positioning at Junctions and Roundabouts
Choosing the wrong lane, positioning too far left before a right turn or cutting across lanes on a roundabout can confuse or obstruct other road users.
How to improve: Read signs and road markings early. Select the correct lane in good time, keep a stable road position and avoid last-second lane changes. If you take the wrong route safely, continue safely—going the wrong way is not automatically a driving fault.
5. Responding Incorrectly to Traffic Lights, Signs or Road Markings
Examples include reacting late to a speed-limit change, stopping beyond the correct line, entering a blocked box junction, ignoring lane arrows or failing to move when a green light shows and the way ahead is clear.
How to improve: Scan further ahead so information does not arrive as a surprise. Identify the sign, marking or light, decide what it requires and respond smoothly. Do not follow another vehicle blindly; confirm that the signal and road ahead allow you to proceed.
6. Poor Steering Control
Steering too early or too late can cause the car to mount the kerb, swing wide or move too close to parked vehicles. Rushed steering can also affect your road position after a turn.
How to improve: Reduce speed before the turn, look where you want the car to go and steer smoothly at the correct time. Practise coordinating speed, clutch control and steering so you are not trying to correct everything at once.
7. Poor Road Position
Driving too close to the kerb, too near the centre line, straddling lanes or staying unnecessarily in the right-hand lane can create risk for other road users.
How to improve: Look well ahead rather than immediately in front of the bonnet. Use road markings and the flow of traffic to maintain a safe, consistent position. Leave suitable clearance when passing parked cars, cyclists and other hazards.
8. Driving at an Unsafe or Inappropriate Speed
Speed faults are not limited to exceeding the speed limit. Driving too fast for bends, weather, visibility or traffic conditions is unsafe, while driving much too slowly without reason can hold up other road users and show poor judgement.
How to improve: Treat the speed limit as a maximum, not a target. Choose a speed that allows you to stop safely within the distance you can see to be clear, then make sensible progress when conditions allow.
9. Losing Control During a Reversing Exercise
During parking or reversing, learners may focus so heavily on accuracy that they forget all-round observation. Other common problems include rushing, touching the kerb or continuing when another road user approaches.
How to improve: Keep the car slow and controllable, observe all around throughout the manoeuvre and pause if the situation changes. A safe correction is better than continuing with a poor position.
10. Letting Nerves Change Your Normal Driving
Nerves do not cause a fail by themselves, but they can lead to rushed decisions, missed observations or overthinking a small mistake. One minor error does not necessarily mean the test is lost.
How to improve: Use mock tests to practise driving independently and following directions under realistic pressure. If you make a mistake, stay calm, return your attention to the road and continue safely.
How to Know When You Are Test-Ready
You are more likely to be ready when you can drive safely and independently across different roads and traffic conditions, not only on familiar routes. You should be able to:
- make observations without repeated prompts
- choose safe gaps and make steady progress
- respond correctly to signs, signals and road markings
- control the car during normal driving and manoeuvres
- deal calmly with unfamiliar situations
- recognise and correct small mistakes safely
Regular manual driving lessons in Loughborough can help turn these skills into consistent habits. If you need concentrated preparation and the format suits your experience, an intensive driving course may also help you build momentum.
Frequently Asked Questions
How many driving faults can I make and still pass?
You can pass with no more than 15 driving faults, provided you make no serious or dangerous faults. However, repeating the same driving fault can show a pattern and may be marked as serious.
Will I fail for taking a wrong turn?
No. The DVSA states that taking a wrong turn is not itself a fault. What matters is that you continue safely and follow the examiner’s directions to return to the route.
Should I book a test before I am fully ready?
A test date should not replace proper preparation. Aim to drive consistently without prompts during lessons and mock tests before taking the practical test.
What should I do after an unsuccessful test?
Use the examiner’s feedback to identify the exact skills that need work. Focus your next lessons on the underlying habit rather than only rehearsing a particular test route.
