Top 10 Reasons Why Learners Fail Their Driving Test (And How to Avoid Them)

Are you preparing for your driving test? Knowing the most common reasons learners fail can help you understand what to practise before test day.

At ZNR Driving School, we help learners develop safe driving habits, improve their confidence and prepare for their practical driving test. Whether you are learning in a manual or automatic car, understanding these common mistakes is an important step towards becoming a safe, independent driver.

The Driver and Vehicle Standards Agency (DVSA) publishes a list of the most common reasons for failing the practical car driving test in Great Britain. Here are the 10 areas every learner should work on.

1. Not making effective observations at junctions

One of the biggest mistakes learners make is failing to observe properly before entering a new road.

For example, you might emerge from a junction without accurately judging the speed of approaching traffic or enter a roundabout when a vehicle approaching from the right is too close.

How to avoid it:

• Look carefully in both directions before emerging.
• Judge the speed and distance of approaching vehicles.
• Choose a safe gap before moving.
• Never rush simply because another driver is waiting behind you.

2. Not using mirrors correctly when changing direction

Your mirrors help you understand what is happening around your vehicle. Forgetting to check them before changing lanes, turning or exiting a roundabout can put other road users at risk.

How to avoid it:

• Check your mirrors before changing direction or position.
• Use the Mirror–Signal–Manoeuvre routine where appropriate.
• Check your mirrors before exiting a roundabout.
• Always make sure it is safe before moving into another lane.

3. Not moving off safely

Learners sometimes move away from the side of the road without making the necessary observations. This can happen when moving off from behind a parked vehicle, on a hill or after completing a manoeuvre.

How to avoid it:

• Check your mirrors and blind spot when necessary.
• Signal when it will benefit other road users.
• Make sure the road is clear before moving.
• Practise moving off in different locations and traffic conditions.

4. Incorrect positioning when turning right at junctions

Incorrect positioning can confuse other drivers and create unnecessary delays. This may happen when turning right at a junction or approaching a roundabout.

How to avoid it:

• Position yourself correctly for your intended direction.
• Use road markings and signs to choose the correct lane.
• Position appropriately while waiting to turn right.
• Check that your position does not obstruct other traffic unnecessarily.

5. Not responding appropriately to traffic lights

Traffic lights require careful observation and good judgement. Learners can make mistakes by proceeding when they should stop, blocking a junction or failing to move when it is safe and appropriate.

How to avoid it:

• Respond correctly to red, amber and green signals.
• Look ahead and anticipate changes.
• Do not enter a junction unless you can clear it safely.
• When turning right, understand when it is safe and lawful to proceed.

Never take a risk at traffic lights just because you are worried about holding up other drivers.

6. Not having proper control of the steering

Poor steering control can cause you to hit the kerb, get too close to parked vehicles or move towards the path of other road users.

How to avoid it:

• Look well ahead rather than concentrating only on the front of the car.
• Steer smoothly and at the appropriate time.
• Practise turns on different roads.
• Maintain suitable clearance from the kerb and parked vehicles.

Your instructor can help you develop consistent steering through regular practice and feedback.

7. Not responding correctly to road markings

Road markings tell you how to position your vehicle and which directions you can take. Missing a lane arrow, straddling lanes or entering a box junction when your exit is blocked can create problems.

How to avoid it:

• Read road markings early.
• Follow lane arrows and directional markings.
• Position yourself in good time.
• Keep a box junction clear unless an exception applies or your exit is clear.

Looking further ahead gives you more time to make the right decision.

8. Not responding correctly to traffic signs

Missing a traffic sign can lead to an incorrect decision, such as choosing the wrong lane, entering a road you should not use or failing to adjust your speed.

How to avoid it:

• Learn the meanings of common traffic signs.
• Look for signs well before junctions and roundabouts.
• Pay attention to temporary signs and roadworks.
• Respond promptly to changes in speed limits.

Understanding traffic signs is essential for safe driving, both during your test and afterwards.

9. Poor positioning on the road during normal driving

Your road position matters even when you are travelling straight ahead. Driving too close to the kerb, too close to the centre line or staying unnecessarily in the right-hand lane can create risks.

How to avoid it:

• Maintain an appropriate position within your lane.
• Leave safe clearance from parked vehicles.
• Avoid unnecessary lane changes.
• Follow the shape of the road through roundabouts.

Ask your instructor for feedback if you find it difficult to judge your position.

10. Not driving at a safe and reasonable speed

Driving too fast for the conditions can be dangerous. However, driving unnecessarily slowly when it is safe to make progress can also affect your driving assessment.

How to avoid it:

• Follow the speed limit.
• Adjust your speed for traffic, weather and visibility.
• Slow down appropriately when approaching hazards.
• Make sure you can stop safely within the distance you can see to be clear.

Remember, the speed limit is not a target. Safe driving means choosing a speed that is appropriate for the conditions.

How can you improve your chances of passing?

Knowing the common mistakes is a good start. The next step is to practise until you can drive safely and consistently without relying on your instructor for prompts.

Here are five ways to prepare:

1. Learn from your mistakes. Work on the faults identified during your lessons.
2. Practise different roads. Include junctions, roundabouts, dual carriageways and busy urban roads.
3. Take mock tests. These help identify areas that need more practice.
4. Build independent driving skills. Practise following road signs and directions confidently.
5. Book your test when you are ready. Aim to demonstrate safe, consistent driving in different situations.

You do not have to be a perfect driver to pass, but you must demonstrate that you can drive safely and independently. Under the standard car driving test rules, you can pass with up to 15 driving faults, provided you have no serious or dangerous faults.
