Common Reasons Learners Fail Their Driving Test: How to Avoid the DVSA's Top 10 Mistakes

Could one of the most common driving test mistakes cause you to fail your practical driving test?

Failing a driving test can be disappointing, particularly after spending time and money preparing for it. However, understanding the common reasons learners make mistakes can help you prepare more effectively and identify areas where you may need more practice before test day.

The DVSA publishes information about the most common reasons people fail the car driving test in Great Britain. The list can change as new data is published, but the latest published Top 10 for the period from April 2024 to March 2025 highlights areas that every learner should pay close attention to.

From observations at junctions and mirror checks to road positioning, steering control and responding correctly to signs and traffic lights, understanding these common mistakes could help you identify weaknesses before they become a problem on your driving test.

In this guide, we explain the common reasons learners fail their driving test and, more importantly, what you can practise to reduce the chances of making the same mistakes.

The DVSA's Top 10 Reasons Learners Fail Their Driving Test

According to DVSA data covering April 2024 to March 2025, the following were the top 10 reasons people failed the car driving test in Great Britain.

Don't just read through the list and assume these mistakes will not apply to you. As you read each section below, think honestly about your own driving and whether there are areas you would benefit from practising with your driving instructor before your test.

  1. Not making effective observations at junctions
  2. Not using mirrors correctly when changing direction
  3. Not moving off safely
  4. Incorrect positioning when turning right at junctions
  5. Not responding appropriately to traffic lights
  6. Not having proper control of the steering
  7. Not responding correctly to road markings
  8. Not responding correctly to traffic signs
  9. Poor positioning on the road during normal driving
  10. Not driving at a safe and reasonable speed

1. Not Making Effective Observations at Junctions

Effective observations at junctions were the number one reason listed in the DVSA's Top 10 for the period covered by the latest published data.

When approaching or emerging from a junction, it is not enough simply to look in a particular direction. Your observations need to be effective, and you must correctly assess what you have seen before deciding whether it is safe to proceed.

This can involve looking for approaching vehicles, pedestrians, cyclists, motorcyclists and other road users.

Common problems can include:

How to practise: Spend time practising different types of junctions, including busy junctions, crossroads, roundabouts and emerging from minor roads. Ask your instructor to help you identify whether your observations are early enough and effective enough.

2. Not Using Mirrors Correctly When Changing Direction

Mirror checks are an essential part of safe driving. During your test, you need to show that you are aware of what is happening around and behind your vehicle before changing direction, position or speed.

A good routine can help mirror checks become a natural part of your driving rather than something you suddenly remember because you are taking your test.

You may need to check your mirrors when:

Simply moving your head is not the aim. Your mirror checks need to be effective, and you need to respond safely to what you see.

How to practise: Work on developing a consistent mirror routine with your driving instructor. Ask them to point out situations where your mirror checks are too late, incomplete or not followed by an appropriate response.

3. Not Moving Off Safely

Moving off safely is something learners do repeatedly during a driving test, so it is important that you remain consistent.

You may need to move off:

Before moving away, you need to make effective observations and make sure it is safe to proceed.

Depending on the situation, this may include checking your mirrors and blind spot and responding appropriately to approaching traffic or other road users.

How to practise: Do not practise moving off only on quiet roads. Ask your instructor to include situations involving parked vehicles, busy roads and slopes so you become comfortable making safe observations in different situations.

4. Incorrect Positioning When Turning Right at Junctions

Correct positioning when turning right is important because it helps make your intentions clear and allows traffic to move safely around you where appropriate.

Learners can make mistakes by:

Your position should always reflect the road layout and the direction you intend to travel.

How to practise: Practise right turns on narrow and wide roads, junctions with lane markings and different types of roundabouts. Make sure you understand why you are choosing a particular road position rather than simply memorising what to do.

5. Not Responding Appropriately to Traffic Lights

Traffic lights may appear straightforward, but mistakes can happen when learners focus only on the colour of the light rather than the situation ahead.

You need to respond appropriately to traffic signals while also continuing to assess whether it is safe and sensible to proceed.

Problems can occur when learners:

A green light does not remove your responsibility to assess what is happening ahead.

How to practise: Drive through a variety of traffic-light-controlled junctions during your lessons and learn to assess the entire situation rather than concentrating only on the traffic light itself.

6. Not Having Proper Control of the Steering

You need to show that you can steer the vehicle smoothly and accurately.

Problems with steering can happen when turning at junctions, driving around bends, passing parked vehicles or pulling up at the side of the road.

Common difficulties can include:

Good steering control develops through regular practice and experience.

How to practise: Ask your instructor to help you focus on looking ahead and planning your position before you reach a bend or junction. Good observations and planning often make steering easier and smoother.

7. Not Responding Correctly to Road Markings

Road markings provide important information about where you should position your vehicle and how you should proceed.

During your driving test, you need to notice road markings early enough to respond safely and correctly.

Examples of situations that require good understanding can include:

A common problem is noticing a road marking too late and then trying to correct the mistake suddenly.

How to practise: Develop the habit of looking well ahead while driving. Your instructor can help you identify road markings early so you have enough time to plan your position and speed.

8. Not Responding Correctly to Traffic Signs

Traffic signs provide instructions, warnings and information that you need to understand and respond to while driving.

During your driving test, you need to notice signs early enough to take appropriate action safely.

Common areas learners should understand include:

It is important not to rely only on your driving instructor telling you where to go. During independent driving, you may need to respond to traffic signs yourself.

How to practise: Continue building your knowledge of road signs and make a habit of identifying signs during every driving lesson rather than treating road signs as something you only revise for your theory test.

9. Poor Positioning on the Road During Normal Driving

Correct road positioning is important throughout your driving test, not just when approaching junctions.

You should be able to position your car appropriately for your intended route while maintaining a safe position within your lane.

Problems can include:

How to practise: Ask yourself regularly whether you are positioned correctly for where you are going next. Looking further ahead can give you more time to choose the correct position.

10. Not Driving at a Safe and Reasonable Speed

Driving at a safe and reasonable speed means considering more than simply staying below the speed limit.

The speed limit is the maximum permitted speed in appropriate conditions. Depending on the road, traffic, weather and visibility, a lower speed may sometimes be necessary.

You need to consider:

Driving unnecessarily slowly without a good reason can also create problems if it affects the normal progress of traffic.

How to practise: Learn to assess the situation continuously. Ask yourself whether your speed gives you enough time and distance to react safely to anything you can see ahead.

Could One of These Mistakes Be Affecting Your Driving?

Reading a list of common driving test mistakes is useful, but the most important question is whether any of these areas are affecting your own driving.

You may feel confident with manoeuvres but struggle with observations. You may be comfortable driving on familiar roads but find busy junctions or roundabouts more difficult.

The best time to identify a weakness is before your driving test, not during it.

Speak honestly with your driving instructor about the areas where you need more practice. An experienced instructor can help you identify patterns in your driving that you may not notice yourself.

Do You Need to Drive Perfectly to Pass?

No. You do not need to drive perfectly to pass your practical driving test.

The driving examiner is assessing whether you can drive safely and independently.

You may make some minor mistakes during your test without failing. However, serious or dangerous mistakes can result in an unsuccessful test.

Try to focus on safe driving rather than trying to make every movement perfect.

Can Nerves Cause You to Fail Your Driving Test?

Feeling nervous before a driving test is completely normal.

You do not fail simply because you are nervous. However, nerves can sometimes affect concentration and decision-making, which may lead to mistakes.

Nerves can sometimes cause learners to:

If you make a small mistake during your test, try not to assume that you have failed. Continue concentrating on the road ahead and focus on driving safely.

How to Reduce Your Chances of Failing Your Driving Test

There is no guaranteed way to pass a driving test, but good preparation can help you feel more confident and ready.

Your driving instructor can help identify areas that need more practice before your test.

Final Thoughts

Understanding the common reasons learners fail their driving test should not make you worry about every possible mistake.

Instead, use the information as a practical checklist to help identify areas where you may need more experience or practice.

The goal is not simply to pass your driving test. The goal is to become a safe, confident and independent driver.

The more experience and understanding you develop during your driving lessons, the better prepared you should feel when your practical driving test arrives.
