Gain a clear understanding of the faults you might make during your practical driving test in Great Britain, including issues with vehicle control, navigating junctions, and hazard perception. This article explains the categories of driving faults, serious faults, and dangerous faults, helping you to recognise and avoid common mistakes that can lead to failing your test.
Article content overview
Passing your practical driving test in Great Britain is a significant milestone, and understanding the potential pitfalls is key to success. The Driving Vehicle Standards Agency (DVSA) assesses your ability to drive safely and competently, and errors are categorised into different types of faults. By familiarising yourself with these fault categories and recognising common mistakes in vehicle control, junction navigation, and hazard perception, you can significantly increase your chances of passing your test and becoming a safe, confident driver on England, Scotland, and Wales's roads.
The DVSA categorises faults made during the practical driving test into three distinct types: driving faults, serious faults, and dangerous faults. Each type carries different implications for your test result. Understanding these distinctions is fundamental to grasping what the examiner is looking for and where potential areas for improvement lie.
To pass your practical driving test, you must achieve a result with no serious or dangerous faults. Additionally, you can incur no more than 15 driving faults throughout the entire test duration. Exceeding this limit for driving faults also leads to a failure.
Precise control over your vehicle is paramount for safe driving. Many common driving test errors stem from a lack of consistent or appropriate control, particularly in scenarios requiring fine adjustments or precise execution. These can range from manoeuvring issues to speed management and even the basic act of stopping and starting.
Issues with car control can manifest in various ways. For example, examiners will closely observe your ability to position the car accurately within its lane, especially when navigating bends or narrow sections of road. Incorrect positioning, such as consistently straddling the centre line or drifting too close to the kerb, can be marked as driving faults. If this poor positioning becomes so severe that it risks mounting the kerb or encroaching on oncoming traffic, it could be escalated to a serious or even dangerous fault.
Speed control is another critical area. Driving too slowly without a valid reason can impede the flow of traffic and is a common driving fault. Conversely, exceeding the speed limit or driving too fast for the prevailing conditions, such as in poor weather or on a slippery surface, can be considered a serious or dangerous fault. Maintaining a speed that is appropriate for the road, traffic, and weather conditions, whilst also being aware of legal speed limits, is essential.
Manoeuvring exercises, such as parallel parking, bay parking, or pulling up on the right-hand side of the road, are often where control issues become most apparent. Failing to position the car correctly before starting the manoeuvre, making excessive steering corrections, or failing to stop within the designated area can all lead to driving faults. For instance, stopping too far from the kerb during a pull-up or parallel park, or being unable to straighten the wheels correctly, are typical errors.
Junctions represent some of the most challenging environments for new drivers. They require a high level of awareness, precise timing, and the ability to correctly interpret priority rules. Mistakes made at junctions are frequently cited as reasons for driving test failure, often due to poor observation or misjudging priority situations.
One of the most significant causes of junction-related faults is inadequate observation. Before emerging from a junction, whether it’s a minor road onto a major one or a crossroads, it is essential to conduct a thorough 'look and think' process. This involves checking mirrors, signalling appropriately, and scanning left, right, and ahead for any approaching traffic, cyclists, or pedestrians. Failing to make these checks, or making them too late, can lead to a serious or dangerous fault if it results in the examiner having to intervene to prevent a collision.
Misjudging priority is another frequent problem. At junctions where traffic lights are absent, priority is often determined by road markings and signs. The 'Give Way' sign, for example, is a clear instruction to allow other traffic to pass first. Similarly, at unmarked junctions, the general rule is to give way to traffic approaching from your right. Failing to do so, or hesitating unnecessarily and holding up traffic when it is safe to proceed, can result in faults.
The Highway Code provides detailed guidance on priority at different types of junctions. Understanding these rules, coupled with diligent observation, is vital. For instance, when emerging from a side road, you must give way to traffic on the main road. If you are turning right across oncoming traffic, you must wait for a large enough gap to complete the manoeuvre safely. Even if you believe you have priority, always be prepared for other road users to make mistakes.
Hazard perception is a critical skill tested not only in the multiple-choice part of the theory test but also implicitly throughout the practical driving test. It refers to your ability to identify potential dangers on the road and react appropriately and in good time to prevent them from developing into actual hazards. Failing to spot developing hazards or reacting too late are common reasons for failure.
During the practical test, the examiner will be observing your awareness of your surroundings. This includes anticipating what other road users might do, such as a pedestrian stepping out from behind a parked car, a cyclist filtering through traffic, or a vehicle emerging unexpectedly from a side road. Your ability to spot these developing hazards and adjust your speed or position accordingly is a key component of safe driving.
A common mistake is to focus too narrowly on the immediate road ahead, neglecting the periphery or potential dangers that are not yet fully formed. For instance, if you see children playing near the roadside, you should anticipate the possibility of one of them running into the road. Similarly, if you notice a car signalling to turn right ahead of you, you should be prepared for them to move into your path.
Reacting to a hazard involves more than just seeing it; it requires a timely and proportionate response. Slamming on the brakes unnecessarily might be as much of a problem as failing to brake at all. The examiner looks for smooth, controlled reactions that maintain safety without causing undue disruption to other road users. This might involve easing off the accelerator, checking mirrors, and preparing to brake, or perhaps adjusting your steering to create more space.
The hazard perception test in the theory exam specifically assesses this skill, but on the road, it is demonstrated through your driving. Examiners are looking for signs that you are constantly scanning, thinking ahead, and anticipating potential problems. This includes checking your mirrors regularly, not just when changing direction or speed, but to be aware of what is happening behind you and to the sides.
Thorough preparation is essential to minimise the risk of making faults on your practical driving test. This involves consistent practice with your approved driving instructor and actively seeking to understand the reasons behind common errors. Don't just learn how to perform manoeuvres; understand the principles of safety and control that underpin them.
Reviewing your performance after each driving lesson is crucial. Discuss any mistakes you made with your instructor and ask for clarification on why it was considered a fault and how to prevent it in the future. Understanding the difference between a minor driving fault and a serious or dangerous fault can help you prioritise your learning. For example, while a few minor slips in gear selection might be acceptable if they don't affect safety, a failure to observe at a junction could be catastrophic.
Familiarise yourself with the DVSA’s guidance on common reasons for failing the driving test. These often highlight the very areas discussed here: observation at junctions, vehicle control (including speed and positioning), and hazard perception. By proactively working on these areas during your practice, you are not only preparing for the test but also for becoming a safer driver for life in Great Britain.
This article explains the three fault categories used by DVSA examiners during the practical driving test: driving faults (minors) are permissible up to 15, serious faults cause automatic failure, and dangerous faults stop the test immediately. Common errors occur in vehicle control through poor positioning, inappropriate speed, and incomplete manoeuvres; at junctions through insufficient observation and priority mistakes; and in hazard perception through reactive rather than proactive responses. Learners should understand these distinctions, practise thorough observation routines, and anticipate developing hazards to maximise their chances of passing.
A short set of high-value points that capture the most important ideas from this article.
The DVSA categorises test faults into driving faults (minors), serious faults (majors), and dangerous faults (immediate failure).
Passing requires zero serious or dangerous faults and no more than 15 driving faults total.
Vehicle control faults include poor lane positioning, inappropriate speed, and failing to complete manoeuvres accurately.
Junction faults primarily stem from inadequate observation and misjudging priority rules.
Hazard perception requires proactive identification of developing dangers, not just reactive responses.
A serious fault automatically fails the test even if no actual danger occurs; a dangerous fault involves actual danger and stops the test immediately.
Before emerging from any junction, scan left, right, and ahead for traffic, cyclists, and pedestrians.
Speed must be appropriate for road, traffic, and weather conditions—neither excessively slow nor exceeding limits.
The Give Way sign and road markings at uncontrolled junctions dictate priority rules that must be followed.
Use mirrors, signal, and manoeuvre routine, but always supplement with advanced observation of surroundings.
Failing to make thorough observation checks at junctions or making them too late, risking serious or dangerous faults.
Driving too slowly without valid reason, impeding traffic flow and earning driving faults.
Focusing narrowly on the road ahead and missing peripheral hazards such as pedestrians behind parked cars.
Misjudging gaps when emerging at junctions or hesitating unnecessarily when it is safe to proceed.
Reacting to hazards abruptly instead of making smooth, controlled adjustments that maintain safety.

The three types of faults are driving faults (minors), serious faults (potentially dangerous), and dangerous faults (actual danger to yourself or others).
Yes, you can pass your practical driving test with up to 15 driving faults. However, you must not have any serious or dangerous faults.
A serious fault is defined as something that is potentially dangerous. If you accumulate serious faults, or if they are numerous, they can lead to a test failure.
Errors in hazard perception, such as failing to spot a developing hazard or not reacting appropriately, can result in driving faults or even serious faults if they create a potential danger.
If you make a dangerous fault, your test will be stopped immediately as it involves actual danger to you, the examiner, or other road users.
