Introduction: Seeing Trouble Before It Happens

The ADI Hazard Perception Test Explained To become a driving instructor, you must do more than drive safely — you need to see danger developing before it unfolds. The ADI Hazard Perception Test is designed to prove that you can.

Part of the ADI Part 1 theory exam, this test checks your ability to spot potential hazards early and react calmly — just as you’ll need to when guiding learners on the road.

What Is the ADI Hazard Perception Test?

The ADI Hazard Perception Test is the second stage of your Part 1 qualification. It follows the multiple-choice section and measures how well you can identify developing hazards — moments when another road user’s actions might make you change speed or direction.

You’ll watch 14 one-minute video clips filmed from the driver’s point of view.
Each clip contains at least one developing hazard, and one clip will include two.

Your task is simple: click the mouse when you spot a developing hazard.

What Is the ADI Hazard Perception Test? What Counts as a Developing Hazard?

A developing hazard is anything that could make a driver take action — like slowing down, steering, or stopping.

Here are some examples:

  • A car turning right across your path
  • A cyclist swerving to avoid a pothole
  • A pedestrian stepping into the road
  • A van reversing out of a driveway

Spot the hazard early and you’ll earn maximum points. Wait too long or click randomly, and your score drops.

Each developing hazard is worth up to 5 points depending on how quickly you respond.
There are 15 hazards in total (one clip contains two), giving a maximum possible score of 75.

You’ll need 57 or more to pass.

What Is the ADI Hazard Perception Test? What the DVSA Is Really Testing

This test isn’t about fast reflexes — it’s about anticipation.

As a driving instructor, you’ll be expected to read the road like a professional. The DVSA wants to see that you can:

  • Recognise potential danger early
  • Predict how situations may develop
  • Respond calmly and in good time

This awareness is what keeps pupils safe, and what helps you manage risk effectively on lessons.

How to Practise for the ADI Hazard Perception Test

Preparation is key. The DVSA offers official practice clips, but structured training can make a world of difference.

Here’s how to sharpen your skills:

  1. Analyse every clip. Don’t just click — understand why the hazard developed.
  2. Practise regularly. The scoring window is tight; get a feel for the timing.
  3. Describe out loud. This helps you think like an instructor, not a driver.
  4. Avoid guessing. A few well-timed clicks beat random ones every time.
  5. Stay focused. Each clip lasts only a minute — concentration matters.

At Driver Training Ltd, we include hazard perception awareness in our ADI Part 1 preparation courses, helping you identify the DVSA’s test patterns and perfect your reactions.

Common Mistakes That Cost Marks

Even confident drivers slip up by:

  • Clicking at everything that moves
  • Hesitating after spotting a hazard
  • Missing hazards due to daydreaming
  • Forgetting there can be two hazards in one clip

A bit of guided practice quickly fixes these habits — and boosts your confidence for the test.

What Is the ADI Hazard Perception Test? What Happens After the Test

Your result appears immediately after completing your ADI Part 1 exam.
If you pass both the multiple-choice and hazard perception sections, you’ll receive a pass certificate and can move forward to Part 2: the Driving Ability Test.

If you don’t pass first time, don’t worry — most candidates succeed on their second attempt once they understand how the scoring window works.
