HGV Show Me Tell Me Questions 2026: Your Essential Guide to Passing Your Practical Test
The HGV practical driving test is a significant milestone on your journey to becoming a professional lorry driver. Beyond demonstrating your driving prowess, a crucial component involves proving your knowledge of vehicle safety and maintenance through the “show me, tell me” questions. These questions, updated for 2026, are designed to assess your ability to conduct essential safety checks, ensuring you can operate a heavy goods vehicle safely and responsibly.
At GS Driver Training, voted Best HGV Training Company for seven consecutive years, we understand the importance of these checks. Our comprehensive training at Dunsfold Aerodrome thoroughly prepares you for every aspect of your HGV test, including mastering the “show me, tell me” section. Getting these questions right not only sets a confident tone for your examiner but also reinforces your commitment to road safety.
Understanding the “Show Me, Tell Me” Format
During your HGV practical test (Part 3b, which costs £115 on weekdays and £141 on evenings/weekends), the examiner will ask you a series of vehicle safety questions. These are divided into two categories:
- “Tell Me” Questions: For these, you will verbally explain how you would perform a specific safety check. The examiner is looking for your theoretical understanding and knowledge of the procedure.
- “Show Me” Questions: Here, you will physically demonstrate how to carry out a safety check on the vehicle. This requires practical application of your knowledge.
You will typically be asked 3 to 5 questions in total. While incorrect answers won\'t result in an automatic failure, each mistake is recorded as a minor fault. Accumulating too many minor faults can impact your overall test result, so it\'s vital to be well-prepared. Our HGV Class 2 (Cat C) training and HGV Class 1 (Cat C+E) training programmes integrate thorough preparation for these questions.
The Complete List of HGV “Show Me, Tell Me” Questions for 2026
“Tell Me” Questions: Explaining Your Safety Checks
These questions require you to articulate the steps involved in performing a safety check without physically doing them.
Q: Tell me how you would check that the brakes are working before starting a journey.
A: Before moving off, I would press the brake pedal firmly. It should feel firm and not spongy or go to the floor. I would then start the engine and ensure the air pressure gauge builds to the correct operating level, typically 6-8 bar. Before fully setting off, I would test the footbrake at a low speed to ensure the vehicle doesn\'t pull to one side. Finally, I would check that the parking brake effectively holds the vehicle on a slope.
Q: Tell me how you would check that the power-assisted steering is working before starting a journey.
A: With the engine off, I would turn the steering wheel slightly until resistance is felt. Then, I would start the engine, and the steering should become noticeably lighter as the power assistance engages. If the steering remains heavy or I hear unusual noises, it indicates a potential issue with the power steering system.
Q: Tell me how you would check the tyres to ensure they are safe and legal.
A: I would check all tyres for correct inflation pressure, referring to the manufacturer\'s recommendations. I would visually inspect the tread depth, ensuring it meets the legal minimum of 1mm across three-quarters of the breadth and around the entire circumference. Additionally, I would look for any cuts, bulges, or damage to the sidewalls and ensure no foreign objects are embedded in the tread.
Q: Tell me how you would check the condition of the reflectors and lights.
A: I would conduct a walk-around check of the entire vehicle, inspecting all lights and reflectors for cleanliness, damage, and secure fitment. With the ignition on, I would check the operation of headlights (dipped and main beam), sidelights, rear lights, brake lights, indicators, fog lights, and reversing lights. For brake lights, I would ask someone to assist or use reflections to confirm they are working.
Q: Tell me how you would check the engine oil level.
A: I would ensure the vehicle is parked on level ground and the engine has had time to cool. I would locate the dipstick, remove it, wipe it clean, and reinsert it fully. Upon removing it again, the oil level should be between the minimum and maximum marks. If low, I would top up with the correct grade of oil as specified in the vehicle handbook.
Q: Tell me how you would check the coolant level.
A: I would check the coolant level in the expansion tank when the engine is cold, ensuring it is between the minimum and maximum marks. It\'s crucial never to remove the radiator cap when the engine is hot due to the risk of scalding. If the level is low, I would top up with the correct coolant mixture according to the vehicle\'s specifications.
Q: Tell me how you would check the windscreen washer fluid level.
A: I would visually inspect the washer fluid reservoir, ensuring the level is adequate. If it\'s low, I would top it up with an appropriate screen wash solution to ensure clear visibility during driving.
“Show Me” Questions: Demonstrating Your Knowledge
These questions require you to physically perform the safety check on the HGV.
Q: Show me how you would check the air pressure is building correctly.
A: I would start the engine and direct the examiner\'s attention to the air pressure gauge(s) on the dashboard. I would explain that the pressure should build steadily, and the low air pressure warning light or buzzer should extinguish once sufficient pressure (typically 6-8 bar) is reached, indicating the braking system is ready for operation.
Q: Show me how you would check the horn is working.
A: I would press the horn button on the steering wheel, ensuring it produces a clear, audible sound. I would only perform this demonstration when it is safe and appropriate to do so, being mindful of other road users and pedestrians.
Q: Show me how you would check the windscreen washers and wipers are working.
A: I would operate the windscreen washer control, confirming that fluid sprays onto the windscreen. Then, I would operate the wipers, ensuring they clear the screen effectively without smearing or juddering. I would also briefly check the condition of the wiper blades for any signs of wear or damage.
Q: Show me how you would check the operation of the main beam headlights.
A: I would switch on the ignition, then activate the main beam headlights (usually by pushing the indicator stalk forward). I would point out the main beam warning light on the dashboard and, if safe, visually confirm the main beams are illuminated from outside the vehicle.
Why These Checks Matter: Beyond the Test
While passing the “show me, tell me” section is essential for your HGV practical test, the underlying knowledge is critical for your career as a professional HGV driver. Regular vehicle checks are not just about compliance; they are fundamental to:
- Road Safety: Identifying potential faults before a journey can prevent accidents and ensure the safety of yourself and other road users.
- Legal Compliance: As an HGV driver, you have a legal responsibility to ensure your vehicle is roadworthy. Failing to do so can lead to fines, penalties, and even loss of your licence.
- Vehicle Longevity: Early detection of issues can prevent minor problems from escalating into costly repairs, extending the lifespan of the vehicle.
- Professionalism: A diligent approach to vehicle checks demonstrates professionalism and attention to detail, qualities highly valued by employers.
The HGV driver shortage, currently estimated at 18,000–25,000 (down from a peak of 70,000+ in 2021), means skilled and responsible drivers are in high demand. Demonstrating a thorough understanding of vehicle safety will make you a more attractive candidate for employers, with Class 2 newly qualified drivers earning £28,000–£35,000 and experienced Class 1 drivers earning £40,000–£55,000 in 2026.
Tips for Success on Test Day

- Understand, Don\'t Memorise: The examiner wants to see genuine understanding, not rote memorisation. Use your own words to explain the checks, demonstrating that you grasp the principles behind them.
- Stay Calm and Think: If you\'re unsure about a question, take a moment to compose yourself. A thoughtful, accurate answer is always better than a rushed, incorrect one.
- Know Your Vehicle: Familiarise yourself with the location of key components like the dipstick, coolant reservoir, washer fluid, and all dashboard controls. This will save you time and stress during the “show me” section.
- Ask Questions During Training: Don\'t hesitate to ask your instructor for clarification on any aspect of the checks. That\'s what they\'re there for!
Frequently Asked Questions (FAQs)
Q: What happens if I get a “show me, tell me” question wrong?
A: Each incorrect answer counts as a minor fault. While it won\'t automatically fail you, accumulating too many minor faults can lead to a test failure. It\'s best to aim for zero faults in this section.
Q: Do I need to know specific technical terms?
A: You don\'t need to be a mechanic, but you should use appropriate terminology where relevant. The key is to clearly explain or demonstrate your understanding of the safety check in a way the examiner can follow.
Q: Are the questions different for Class 1 (Cat C+E) and Class 2 (Cat C) HGV tests?
A: The core principles and types of questions are generally the same, focusing on the safety of the vehicle. However, Class 1 vehicles (articulated lorries) may have additional checks related to the trailer coupling and braking systems. Your GS Driver Training instructor will cover all relevant questions for your specific licence category.
Q: Can I fail my HGV practical test just on “show me, tell me” questions?
A: No, you cannot fail the entire practical test solely on the “show me, tell me” questions. However, the minor faults accumulated here contribute to your overall fault count. If these, combined with any driving faults, exceed the permitted limit, you would fail the test.
Q: Where can I find more information about the HGV theory test?
