Mastering the Show Me, Tell Me Questions on Your Driving Test

Before you can secure your full Great Britain driving licence, you must demonstrate to your DVSA examiner that you know how to keep your vehicle safe and roadworthy. The 'Show Me, Tell Me' questions assess this essential capability in two distinct phases: one verbal safety explanation before you set off, and one practical demonstration of secondary controls while driving. Thorough preparation on these questions is highly recommended to build safe vehicle maintenance habits and avoid picking up avoidable driving faults during your test.

Essential Facts About Show Me, Tell Me Questions

Quickly understand the most important facts, rules, and meanings related to Show Me, Tell Me Questions in British driving theory for Great Britain. This focused summary helps learners revise key terminology, traffic concepts, and exam-relevant knowledge efficiently.

You are asked one verbal 'Tell Me' question before driving, and one practical 'Show Me' demonstration on the move.
Incorrect answers only incur a maximum of one driving fault (minor) and do not cause an automatic test failure.
For 'Tell Me' questions, you must be prepared to open the bonnet and point to fluid reservoirs or the engine dipstick.
For 'Show Me' questions, maintaining perfect control of the steering wheel and lane position is more important than rushing the task.
Always perform the 'Show Me' task when it is safe to do so, using quick glances rather than staring at the dashboard controls.

Real Driving Examples of Show Me, Tell Me Questions

See how Show Me, Tell Me Questions appears in realistic driving situations relevant to Great Britain. These examples explain correct behaviour, safety implications, and how Show Me, Tell Me Questions connects to British driving theory exam questions.

Situation

At the start of the practical test, before starting the engine, the examiner asks you to explain how you would check that the engine has sufficient oil.

Correct action

Point to the engine dipstick, explain that you would pull it out, wipe it clean with a rag, reinsert it fully, pull it out again, and check the oil level against the minimum and maximum markers.

Why it matters

This is a 'Tell Me' question. You do not need to perform the check physically or wait for the engine to cool down; you only need to explain the correct sequence of steps clearly to the examiner.

Situation

While you are actively driving along a safe stretch of road, the examiner asks you to show them how you would operate the horn.

Correct action

While keeping your eyes on the road and maintaining complete control of the steering wheel, briefly press the center of the steering wheel to sound the horn when it is safe to do so.

Why it matters

This is a 'Show Me' question. It tests your ability to operate secondary vehicle controls while driving without losing situational awareness or steering control.

Situation

During the drive, the examiner asks you to show them how you would clear the windscreen using the front demister.

Correct action

Locate the front demister control on the dashboard by touch and quick glances, turn it on to clear the glass, ensuring you do not drift or lose concentration on the road ahead.

Why it matters

The 'Show Me' questions assess whether you can operate everyday auxiliary controls under real-world driving conditions safely without diverting your main attention from the road.

Show Me, Tell Me Questions

A complete guide to the mandatory vehicle safety questions asked during the GB practical driving test, covering both engine checks and on-the-move operations.

What Are the Show Me, Tell Me Questions?

The 'Show Me, Tell Me' questions are a core part of the practical driving test in Great Britain, administered by the Driver and Vehicle Standards Agency (DVSA). Designed to test your knowledge of basic vehicle safety and maintenance, these questions ensure that all new drivers understand how to perform safety checks and use primary and secondary controls before they drive unsupervised.

Rather than testing professional mechanical skills, the assessment focuses on the everyday checks that keep a car roadworthy and safe. This includes monitoring tyre safety, verifying fluid levels under the bonnet, and operating safety controls like windscreen demisters or headlights while driving.

The Key Difference Between Tell Me and Show Me

The driving test evaluates safety checks in two distinct ways, separated by when they are asked and how you respond:

  • The 'Tell Me' Question: This is asked at the very start of your practical test, before you start the engine. You do not need to physically perform the action; instead, you must verbally explain to the examiner how you would carry out a specific safety check. A classic example is explaining how to check that the engine oil level is correct.
  • The 'Show Me' Question: This is asked while you are actively driving. The examiner will choose a safe stretch of road and ask you to physically demonstrate how to operate a specific control, such as turning on your dipped headlights or using the horn, without losing safe control of the car.

Common Tell Me Questions and Explanations

For the 'Tell Me' portion of the test, the examiner may ask you to open the bonnet or explain a control inside the vehicle. Here are common checks you must be prepared to explain:

  • Checking Engine Oil: Explain that you would open the bonnet, locate the dipstick, pull it out, and wipe it clean. Then, you would insert it fully back, pull it out once more, and check that the oil mark falls between the minimum and maximum indicator lines.
  • Checking Brake Fluid: Locate the brake fluid reservoir under the bonnet and explain how you would check the fluid level against the high and low markings on the side of the translucent container.
  • Checking Engine Coolant: Identify the coolant reservoir under the bonnet and explain that you would check the level against the minimum and maximum markings, emphasizing that you should never open the cap while the engine is hot.
  • Checking Tyre Tread and Condition: Explain that tyres must have a minimum tread depth of 1.6mm across the central three-quarters of the breadth of the tyre and around its entire outer circumference, with no cuts or bulges in the sidewalls.

Handling Show Me Questions Safely on the Move

The 'Show Me' task is designed to check that you can operate auxiliary controls while maintaining proper lane discipline and situational awareness. The examiner will ask you to show them how to perform a task such as:

  • Washing and cleaning the rear or front windscreen.
  • Demisting the front windscreen or rear window.
  • Turning on your dipped headlights.
  • Opening and closing the side window.
  • Operating the horn.

When asked to perform a 'Show Me' action, do not rush. Take a moment to assess the road ahead. Wait for a straight, quiet section of road, keep your eyes primarily on the path ahead, and use quick glances to locate and operate the control. Losing steering control, drifting across road markings, or tailgating while performing a 'Show Me' task can lead to a serious or dangerous fault.

How the Questions Are Marked on the Driving Test

Many learner drivers worry that answering a safety question incorrectly will result in an immediate test failure. This is not the case.

If you answer either the 'Tell Me' question, the 'Show Me' question, or both questions incorrectly, you will only receive one driving fault (often referred to as a 'minor'). You cannot fail your test solely because of incorrect verbal answers. However, if your physical execution of the 'Show Me' question while driving compromises safety—such as steering poorly or failing to observe a hazard—the examiner may record a serious or dangerous fault, which will result in an automatic test failure.

Show Me, Tell Me Questions Driving Theory Questions and Answers

Get clear answers to the most searched questions about Show Me, Tell Me Questions in British driving theory for Great Britain. This FAQ explains the definition, real exam context, practical meaning, and common learner doubts to support confident theory test preparation.

When are the Show Me, Tell Me questions asked during the practical test?

The 'Tell Me' question is asked at the very beginning of the driving test, before you start the engine. The 'Show Me' question is asked while you are actively driving on the road when the examiner deems it safe to do so.

What happens if I get a Show Me, Tell Me question wrong?

If you answer one or both of the questions incorrectly, you will receive a single driving fault (commonly called a minor). This will not cause you to automatically fail the practical driving test, unless your attempt causes a dangerous situation.

Will I have to open the car bonnet for the questions?

Yes, some of the 'Tell Me' questions require you to explain how you would check fluid levels, which involves identifying where the engine oil, coolant, brake fluid, or windscreen washer reservoir is located under the bonnet.

Can I lose control of the car during the Show Me question?

No, maintaining safe vehicle control is critical. If you lose control, veer out of your lane, or take your eyes off the road for too long while demonstrating a task, the examiner may mark it as a serious or dangerous fault, resulting in a test failure.

Are the Show Me, Tell Me questions the same in Northern Ireland?

Yes, both Great Britain (DVSA) and Northern Ireland (DVA) use the 'Show Me, Tell Me' format during their practical tests, but minor procedural details and localized driving restrictions, like the 45 mph limit for learners in NI, can differ.
