What is the HGV Hazard Perception Test?
The HGV hazard perception test is a critical component of obtaining your Heavy Goods Vehicle (HGV) driving licence. It evaluates your ability to spot potential dangers and developing hazards on the road as a driver would experience them. Passing this test is mandatory before you can book your practical HGV driving test, making it a significant step in your journey to professional driving.
- Tests ability to spot developing road hazards.
- Mandatory before booking HGV practical test.
- Assesses reaction and judgement skills.
- Uses video clips simulating driving scenarios.
Often taken alongside the HGV multiple-choice theory test, the hazard perception element uses video clips that simulate various driving conditions and scenarios. You will watch these clips from the perspective of a driver and must click the mouse or tap the screen whenever you see a developing hazard that might require you to take action, such as braking or steering.
The scoring system is designed to reward early identification of hazards. The sooner you identify a developing hazard, the higher your score for that particular incident. However, you must avoid 'touting' – clicking unnecessarily – as this can lead to a zero score for that clip. This test is not about simply identifying static dangers like parked cars, but rather about recognising situations that could escalate into a risk.
Understanding the purpose and format of the test is the first step towards successful preparation. It requires a different kind of thinking than the multiple-choice section, focusing more on instinct, observation, and judgement under pressure. It's a direct simulation of the real-world challenges faced by HGV drivers every day.
Why is Hazard Perception Crucial for HGV Drivers?
As an HGV driver, your responsibility extends far beyond your own vehicle. You are operating large, heavy machinery that requires significant stopping distances and has a wider turning radius. Consequently, your ability to anticipate potential problems – from a child chasing a ball towards the road to a car braking suddenly ahead – is paramount. The hazard perception test is designed to verify that you possess this essential defensive driving skill.
Professional drivers must maintain a constant state of vigilance. This means continuously scanning the environment, anticipating the actions of other road users (pedestrians, cyclists, other vehicles), and being aware of road conditions, weather, and your vehicle’s limitations. The test reflects these demands, pushing you to think ahead and react appropriately to prevent accidents.
The stakes are incredibly high in professional driving. A moment's inattention or a misjudged hazard can have severe consequences. Therefore, the hazard perception test serves as an important gatekeeper, ensuring that only drivers demonstrating a competent level of risk awareness can proceed to the practical driving stage. It underpins the safety of not just the driver, but also other road users and the general public.
The core principle of the HGV hazard perception test is to gauge your proactive approach to road safety.
HGV Licence Theory Test Structure
The HGV theory test is comprised of two parts: the multiple-choice questions and the hazard perception test. While they are often booked together, they are distinct assessments. You must pass both parts to satisfy the theory test requirement for your HGV licence.
The multiple-choice section covers a broad range of topics relevant to HGV driving, including vehicle operation, road safety, driver hours, health and safety, and legal requirements. This part tests your knowledge of rules and best practices. The hazard perception test, however, tests your practical application of this knowledge in dynamic, real-world scenarios.
The format is typically administered on a computer. You’ll usually complete the multiple-choice questions first. Once you pass that section, you can proceed to the hazard perception clips. Some candidates prefer to tackle the hazard perception test first, so it's worth checking the booking system's options. Regardless of the order, both must be passed within the same sitting to be considered a complete pass of the theory test.
The structure ensures a comprehensive evaluation of a potential HGV driver’s readiness. Knowledge alone is insufficient; the ability to apply that knowledge safely and reactively on the road is equally vital. The hazard perception test is the primary method for assessing this crucial skill.
How the HGV Hazard Perception Test Works
The HGV hazard perception test presents you with 14 video clips, each lasting about a minute. In one of these clips, there will be two developing hazards. You need to identify these by clicking your mouse or tapping the screen as soon as you spot a hazard that might lead to you taking action, such as changing speed or direction.
The system scores your response based on how quickly you identify the developing hazard. The earlier you click, the higher the mark you receive. There are five scoring points available for each hazard. For example, if you click when the hazard is just starting to develop, you might get five points. If you wait until it’s more obvious, you might only get one or two points, or even zero if you click too late or not at all.
It is crucial to understand what constitutes a 'developing hazard'. This is something that would naturally cause you to take action, like a pedestrian stepping out from behind a parked car, a vehicle signalling to pull out in front of you, or a cyclist swerving. Static hazards, such as a parked car or a pothole that isn't causing an immediate issue, do not count towards the score unless they become a developing hazard.
Accuracy in identifying early signs is rewarded by the scoring system.
Scoring and Pass Mark
To pass the HGV hazard perception test, you need to score at least 57 out of a possible 75 points. This score is cumulative across all the video clips shown. The scoring mechanism is designed to encourage vigilance and early recognition. Each hazard has a 'ticking clock' associated with its development, and your score decreases the longer you take to identify it.
The test is designed to be challenging but fair. It simulates real-life situations that HGV drivers encounter daily. The pass mark of 57 is set to ensure a competent level of hazard awareness. It's not about perfect recall, but about demonstrating a consistent ability to scan, identify, and anticipate risks.
Remember, there are no penalties for clicking too early or for clicking on non-hazards (touting). However, if you click on a non-hazard, you will score zero for that particular click, and it may affect your overall score if it happens repeatedly. The goal is to click only when a real, developing hazard is present.
The test administration software is sensitive to rapid, repeated clicking, which is often an indicator of 'touting'. Therefore, a steady, considered approach is generally more effective than a frantic clicking spree. You are given a short period after each clip to record your response, giving you a moment to confirm your judgement.
What Constitutes a Developing Hazard?
A developing hazard is defined as something that might cause you to take action, such as changing your speed or direction. This could be anything from a child’s ball rolling into the road, suggesting a child might follow, to a car ahead with its brake lights on, indicating it might stop suddenly. Other examples include a vehicle emerging from a junction, a pedestrian looking as if they might step into the road, or a cyclist moving unpredictably.
It's important to distinguish these from static hazards, like a parked car, a road sign, or a pothole that isn’t currently affecting traffic flow. While these are things to be aware of, they only become developing hazards if they create a situation that requires an immediate response from you. For instance, a parked car becomes a developing hazard if its driver starts indicating to pull out, or if a pedestrian is about to walk out from behind it.
The test is about anticipation. You're expected to see the early signs and react before the situation becomes critical. This involves looking far down the road, checking your mirrors, and understanding the potential behaviour of other road users and environmental factors. For instance, if you see a lorry parked on a blind bend, that's a static hazard. If a car ahead suddenly brakes hard, that's a developing hazard.
The emphasis is on *developing*. This means the situation is evolving and presenting a potential risk that requires your attention and possible action. It’s about spotting the precursor to danger, not just the danger itself.
Booking Your HGV Hazard Perception Test
Booking your HGV hazard perception test is a straightforward process, usually done online through the official government website responsible for booking driving tests in your region. You will need to have passed your HGV multiple-choice theory test before you can book the hazard perception part, or you can book them together if the system allows.
You can book your test up to 8 weeks in advance, and you'll need your driving licence number. It’s advisable to book well in advance, especially if you have specific dates or times in mind, as popular slots can fill up quickly. The booking system will present you with available dates and times at test centres near you.
The official booking portal is the most reliable place to secure your slot. Be wary of third-party websites that might charge additional fees for booking. The price for the test is standard across all centres, and you can usually check the current theory test price on the government's official driving test information pages.
Securing your appointment promptly is key to maintaining your licence progression timeline.
What You Need to Book
To book your HGV hazard perception test, you will typically need the following:
- Your UK driving licence number.
- A credit or debit card for payment.
- Details of your chosen test centre and preferred dates/times.
If you are booking for a category of licence that requires a specific medical examination first (e.g., for larger HGV categories), ensure this is completed and processed before you attempt to book your theory tests, as it can sometimes affect eligibility or booking availability.
It’s always good practice to double-check the official government website for the most up-to-date requirements and procedures. Regulations and booking platforms can sometimes be updated, and staying informed ensures a smooth booking experience.
Changing or Cancelling Your Test
If you need to change or cancel your HGV hazard perception test, you can usually do so online via the same portal where you booked it. There are specific rules regarding how far in advance you must make changes or cancellations to avoid losing your fee. Generally, you need to give at least 3 clear working days’ notice.
If you cancel or change your test with sufficient notice, you will typically be eligible for a full refund or can reschedule without penalty. If you do not provide enough notice, or if you fail to attend your test, you will forfeit the test fee and will need to book and pay for a new test.
Always review the cancellation and rescheduling policy on the official booking website carefully. This ensures you understand the terms and conditions to avoid unexpected charges or the loss of your test fee. Planning your test date with some flexibility can help mitigate issues if unforeseen circumstances arise.
The ability to reschedule is a vital safeguard for candidates. Life happens, and having the option to adjust your booking, provided you adhere to the notice periods, allows for greater flexibility and reduces stress around test day planning. It’s always best to manage your booking as soon as you know a change is needed.
Preparing for the HGV Hazard Perception Test
Effective preparation is vital for passing the HGV hazard perception test. While you cannot 'learn' the specific video clips as they are varied, you can learn how to identify developing hazards and practise recognising them under timed conditions. This involves understanding the principles of defensive driving and applying them to the test format.
The most recommended method is to use official practice materials or reputable third-party resources that simulate the test environment. These resources often include a wide range of clips, feedback mechanisms, and explanations of why certain situations are hazards. Regularly practising with these tools will build your confidence and hone your observational skills.
Familiarise yourself with the types of hazards commonly encountered by HGV drivers. This includes issues related to the vehicle's size, such as blind spots and longer braking distances, as well as common road scenarios like junctions, pedestrian crossings, cyclists, and varying weather conditions. Understanding these common scenarios will help you anticipate them.
Consistent practice is the cornerstone of success in this test.
Using Practice Materials Effectively
When using practice materials, treat them as if you are taking the real test. Find a quiet space, ensure you won't be interrupted, and use a computer with a mouse. Try to replicate the test conditions as closely as possible.
After completing a set of practice clips, review your performance carefully. Pay attention to any hazards you missed or identified too late. Most practice software provides detailed feedback, explaining what the hazard was, why it was a hazard, and the optimal time to have clicked. Use this feedback to learn and improve for the next session.
Don't just aim to pass the practice tests; aim to understand the underlying reasons behind each hazard. This deeper understanding will serve you better on the actual test day and, more importantly, in your future career as an HGV driver. Look for resources that offer a large bank of clips, as this will expose you to a wider variety of situations.
Consider using resources that include explanations from experienced instructors or former examiners. Their insights can provide valuable context and help you interpret scenarios that might otherwise seem ambiguous. The goal is to develop a consistent, reliable method for spotting hazards.
Tips for Test Day
On the day of your HGV hazard perception test, ensure you arrive at the test centre with plenty of time to spare. This helps reduce stress and allows you to settle in before the test begins. Bring the required identification, which is usually your photocard driving licence.
Before the actual test starts, you will be shown a tutorial demonstrating how to use the computer interface and how the scoring works. Take this tutorial seriously, as it will familiarise you with the controls and scoring system, preventing any technical confusion during the test itself.
During the clips, try to maintain a calm and focused demeanour. Avoid overthinking or trying to second-guess the system. Trust your instincts and your preparation. Remember to click as soon as you see a developing hazard, but avoid clicking repeatedly or on non-hazards.
Stay calm and trust your preparation.
If you encounter a clip that seems particularly difficult or confusing, don't dwell on it. Move on to the next one and focus your energy there. The test is cumulative, so a single difficult clip shouldn't derail your entire performance if you've prepared well.
Common Pitfalls and How to Avoid Them
Many candidates make the same mistakes when preparing for or taking the HGV hazard perception test. Awareness of these common pitfalls is the first step to avoiding them and ensuring you achieve the required score.
One of the most frequent errors is 'touting' – clicking unnecessarily on static objects or non-hazards. This can lead to zero scores for clicks and may even result in a zero score for the entire clip if the system detects a pattern of excessive clicking. Candidates often do this out of nervousness or a misunderstanding of what constitutes a developing hazard.
Another pitfall is identifying hazards too late. This means the situation has already progressed significantly, and you'll receive fewer points. This often stems from not scanning the periphery or not anticipating potential dangers, such as a child playing near a road or a car signalling to turn.
Overthinking a clip can be as detrimental as not clicking at all.
Misinterpreting Static vs. Developing Hazards
A key area of confusion is the distinction between static and developing hazards. A static hazard is something that is present but not currently posing an immediate threat. Examples include a parked car, a road sign, or a pothole. A developing hazard is something that *could* cause you to take action. For instance, a parked car becomes a developing hazard if its door opens suddenly, or if a pedestrian steps out from behind it.
Candidates often mistakenly click on static objects, assuming they are hazards. The test specifically looks for your ability to anticipate *change* and *potential risk*. Practising with materials that clearly differentiate between the two is essential for understanding this nuance.
Focus on the 'developing' aspect. Ask yourself: 'Is this situation likely to require me to brake, steer, or change speed in the near future?' If the answer is yes, it's a developing hazard. If it’s just an object on the road that you can safely pass, it’s likely static.
The scoring system rewards early recognition of these developing situations. Therefore, learning to spot the subtle cues that indicate a situation is about to become dangerous is paramount.
Nervousness and Time Pressure
Test day nerves are common and can significantly impact performance. The pressure of time, combined with the visual nature of the test, can lead to rushed decisions or an inability to concentrate. This is where thorough practice in simulated conditions becomes invaluable.
To combat nervousness, ensure you are well-rested and have a clear understanding of the test procedure. Arriving early at the test centre can also help you acclimatise to the environment. During the test, take a moment to breathe and focus on the tutorial. Remind yourself that you have prepared and are capable of passing.
If you find yourself getting flustered by a particular clip, resist the urge to dwell on it. Move on to the next one and try to regain your composure. Each clip is scored independently, and one difficult scenario doesn't mean you've failed. Focus on maintaining a consistent, observant approach throughout the entire test.
Remember, the test is designed to assess your everyday driving awareness. By approaching it with a clear mind and trusting your preparation, you can manage the pressure effectively.
HGV vs. Car Hazard Perception Test Differences
While the fundamental principle of the hazard perception test remains the same whether for a car or an HGV licence, there are crucial differences in the scenarios presented and the expectations placed upon the driver. The HGV test focuses on hazards relevant to operating a large, heavy vehicle.
Scenarios in the HGV test will often involve situations where the vehicle's size, weight, and handling characteristics are key factors. This includes dealing with longer braking distances, wider turning circles, limited visibility (especially directly behind and to the sides), and the impact of other road users on a large vehicle.
For example, a car driver might need to be aware of a car cutting them off. An HGV driver, however, needs to consider not just that scenario, but also how their own vehicle's size might affect other drivers' actions, or how a sudden manoeuvre by them could create a hazard for smaller vehicles or cyclists operating in their blind spots.
Understanding the unique dynamics of HGV driving is central to this test.
Vehicle Size and Handling Considerations
The physical dimensions and weight of an HGV mean that hazards can develop differently and require different responses compared to a car. You might see clips showing situations where:
- A car misjudges the space needed for an HGV to turn, pulling out too soon.
- A smaller vehicle is hidden in the HGV's blind spot, potentially moving into its path.
- The HGV needs a much larger gap in traffic to merge or change lanes safely.
- A sudden stop by the HGV could cause a chain reaction due to its momentum.
- The driver needs to be aware of overhanging structures or low bridges.
These scenarios demand a higher level of foresight and consideration for the vehicle's capabilities and limitations. The hazards are often more complex, involving multiple interacting elements and a greater potential for severe consequences.
The scoring criteria are also calibrated to reflect the heightened responsibility of an HGV driver. Early and appropriate identification of hazards is critical, as the margin for error is smaller.
Road Positioning and Awareness
For HGV drivers, road positioning is a critical aspect of hazard perception. This includes understanding where to be on the road to maximise visibility, minimise risk, and allow space for other road users. Scenarios might involve:
- Choosing the correct lane on approach to a roundabout or junction.
- Positioning the vehicle to avoid the 'cut-in' of smaller vehicles at junctions.
- Being aware of cyclists or motorcyclists who might filter through traffic.
- Anticipating pedestrian behaviour near roadsides, especially in urban environments.
The hazard perception test for HGVs places a strong emphasis on anticipating the actions of others and understanding how your vehicle’s presence affects them. It's about managing the space around your large vehicle proactively.
This requires a constant assessment of your surroundings, looking far ahead and to the sides, and using your mirrors effectively. The HGV test requires a more advanced level of situational awareness than the car test, reflecting the increased risk and responsibility associated with larger vehicles.
Understanding the Pass Mark and Scoring
The HGV hazard perception test requires a minimum score of 57 points out of a possible 75 to pass. This score is accumulated from your responses across 14 video clips, one of which contains two separate developing hazards. The scoring system is designed to reward early recognition of potential dangers.
Each developing hazard can earn you up to five points, with the score decreasing the longer it takes you to identify it. For instance, clicking immediately as a hazard starts to form might earn five points. Clicking when it's more obvious, but still requires action, could earn three or two points. If you click too late, you might only get one point, or zero if the hazard has already passed or is no longer developing.
It's crucial to understand that the test is not about simply clicking on anything that looks potentially dangerous. Clicking on static objects or non-hazards ('touting') will not earn you points for that click and, if done excessively, can lead to a zero score for the entire clip, negatively impacting your overall result.
The scoring rewards timely and accurate identification.
The 'Touting' Penalty
The term 'touting' refers to clicking the mouse repeatedly or clicking on non-hazards. While a single click on a non-hazard doesn't automatically fail you, the system is programmed to detect patterns of excessive or inappropriate clicking. If the system flags a clip for touting, you will receive a zero score for that clip, irrespective of whether you identified any actual hazards.
This is why a calm, measured approach is advised. Avoid frantic clicking. Instead, observe the scene, identify a developing hazard, and click once to register your response. If there are multiple developing hazards within a clip, you can click for each one as it appears.
The aim is to demonstrate your ability to react appropriately to developing situations. Touting suggests a lack of understanding or an inability to distinguish between genuine risks and everyday road features. Practising with materials that simulate this scoring mechanism will help you avoid this pitfall.
How to Maximise Your Score
To maximise your score, focus on scanning the entire screen, including mirrors and peripheral areas, for potential developing hazards. Anticipate what might happen next based on the behaviour of other road users, the road layout, and environmental conditions.
For example, if you see a child playing near the kerb, anticipate that they might run into the road. If a car ahead has its wheels turned towards your lane, anticipate that it might pull out. These are the early warning signs that the test is looking for.
Use the tutorial at the start of the test to understand the controls and scoring. Remember that the pass mark is 57/75, so you don't need a perfect score, but you do need to demonstrate a consistent ability to identify hazards effectively. Aim to score as highly as possible on each clip by identifying hazards as early as you can.
Early identification leads to higher scores.
What Happens After Passing?
Once you have successfully passed both the HGV multiple-choice theory test and the hazard perception test, you have completed the theory stage of your HGV licence acquisition. This means you are now eligible to book your practical HGV driving test.
Your theory test pass certificate is usually valid for a specific period. It is essential to book and pass your practical driving test within this validity period. If your theory test expires, you will need to retake and pass both the multiple-choice and hazard perception tests again before you can book your practical test.
The practical test is the final hurdle, where you demonstrate your driving skills and ability to handle an HGV safely on the road. This test is conducted by an examiner and assesses everything from vehicle control to hazard awareness in real-time driving scenarios.
Passing the theory section unlocks the next stage: practical training and testing.
Booking Your Practical HGV Driving Test
Booking your practical HGV driving test follows a similar process to booking the theory tests, usually through the same official government portal. You will need to have your theory test pass details ready, as these will be required for booking. Ensure your theory test is still valid.
Practical test slots can also be in high demand, so it's advisable to book as far in advance as possible. You may also need to arrange lessons with an approved HGV driving instructor. Many instructors will advise you on when to book your practical test based on your progress during training.
The practical test itself is usually conducted in two parts: a vehicle safety check (often referred to as the 'show me, tell me' questions), an off-road manoeuvre (such as a bay park or pulling up on the right), and an on-road driving assessment. The on-road assessment will include hazard perception elements, similar to the test you've just passed, but assessed by a human examiner in real-time.
Maintaining Your HGV Licence
After obtaining your HGV licence, your responsibility for road safety continues. The hazard perception test is designed to instil safe driving habits that should be maintained throughout your career. Continuous professional development (CPD) and ongoing training, such as Driver CPC (Certificate of Professional Competence), are often required for professional HGV drivers to keep their skills and knowledge up to date.
Driver CPC requires periodic training every five years, ensuring drivers remain competent and aware of the latest regulations, safety practices, and technologies. This ongoing commitment to learning is vital for maintaining high safety standards in the haulage industry.
The initial hazard perception test is just the beginning of a career focused on safe and responsible driving. By internalising the principles tested, you contribute to safer roads for everyone.
Alternatives and Related Training
While the HGV hazard perception test is a mandatory component of obtaining your licence, there are various related training courses and resources that can significantly enhance your preparedness and overall driving competence. These supplementary options can provide deeper insights and practical experience beyond the test requirements.
Driver CPC (Certificate of Professional Competence) is a mandatory qualification for professional HGV drivers. While it doesn't directly replace the hazard perception test, its periodic training modules often cover advanced hazard awareness, defensive driving techniques, and safe loading/unloading procedures, all of which reinforce the skills tested. Completing CPC training demonstrates a commitment to continuous professional development.
Many driving schools and training providers offer specialised courses in defensive driving or advanced hazard perception for HGV drivers. These courses can go into more detail than the test requires, focusing on anticipating risks in specific scenarios, understanding driver fatigue, and managing complex traffic situations. They offer a more in-depth perspective on safe driving practices.
Investing in advanced training can elevate your driving skills.
Approved Driving Schools and Instructors
Choosing an approved HGV driving school or an instructor with a good track record is paramount. Reputable schools will not only prepare you for the official tests but will also instil a strong foundation in safe driving principles. They have the expertise to identify your weaknesses and tailor training to address them.
When selecting a school, look for those that offer comprehensive training packages, including theory test preparation, hazard perception practice, and practical driving lessons. Ask about their pass rates, instructor qualifications, and the types of vehicles used for training. A good instructor will provide constructive feedback and practical tips that extend beyond what you'll find in study materials.
Many instructors will use their own experience to highlight common hazards and how to manage them, offering real-world context that is invaluable for both the test and your future career. They can also help you understand the nuances of specific HGV manoeuvres and how they relate to hazard perception.
Online Resources and Apps
Beyond official practice tests, a wealth of online resources and mobile applications are available to help you prepare for the HGV hazard perception test. These can offer flexible learning options, allowing you to practise anytime, anywhere.
Look for apps and websites that offer:
- A large library of practice clips.
- Realistic simulations of the DVSA test.
- Detailed explanations and feedback on incorrect responses.
- Performance tracking to monitor your progress.
- Tips and advice from experienced professionals.
Using a combination of these resources can create a robust study plan. For instance, you might use an app for on-the-go revision and a more comprehensive online platform for full mock tests. The key is consistency and using resources that accurately reflect the official test format and difficulty.
These tools provide an excellent opportunity to familiarise yourself with the visual style of the clips and the types of scenarios you might encounter, helping to build your confidence before the actual test day.
Frequently Asked Questions About the HGV Hazard Perception Test
The HGV hazard perception test can raise many questions for prospective drivers. Understanding these common queries can help clarify the process and ease any anxieties you might have about this important stage of obtaining your licence.
Many candidates wonder about the duration of the test. Each video clip is about a minute long, and you watch 14 clips, meaning the hazard perception section itself takes around 15-20 minutes to complete. This is in addition to the multiple-choice part of the theory test.
Another frequent question is about the number of attempts allowed. While there's no limit to the number of times you can take the test, each attempt requires payment. Therefore, it's vital to prepare thoroughly to maximise your chances of passing on the first try.
Clear answers to common questions demystify the test.
What is the pass mark for the HGV hazard perception test?
The pass mark for the HGV hazard perception test is 57 out of a possible 75 points. You achieve this by correctly identifying developing hazards in the video clips, with earlier identification earning more points.
How long does the HGV hazard perception test last?
The hazard perception test consists of 14 video clips. While the clips themselves are approximately one minute each, the total time taken, including the introduction and scoring, is usually around 15-20 minutes.
Can I retake the HGV hazard perception test if I fail?
Yes, you can retake the HGV hazard perception test if you fail. There is no limit to the number of times you can take it, but each attempt requires payment of the test fee. Thorough preparation is recommended to avoid multiple attempts.
What happens if I click too much during the test?
Clicking excessively or on non-hazards is known as 'touting'. If the system detects this behaviour, you will receive a zero score for that particular clip, which can significantly impact your overall score and potentially lead to a fail.
How is the HGV hazard perception test different from the car version?
The HGV test uses scenarios specifically relevant to large goods vehicles, focusing on hazards related to their size, weight, braking distances, and blind spots. While the principle is the same, the complexity and context of the hazards are tailored for professional drivers.
How much does the HGV theory test (including hazard perception) cost?
The theory test price, which covers both the multiple-choice and hazard perception parts, is set by the governing body. You can find the current theory test price on the official government website for driving tests.
When should I book my HGV hazard perception test?
You should book your HGV hazard perception test after you have passed your HGV medical (if applicable) and ideally once you have begun or completed your initial HGV multiple-choice theory training. You can book it up to 8 weeks in advance and must pass it before booking your practical HGV driving test.
