ADI Part 1 Theory Test: Ultimate 2025 Guide to Passing with Confidence

---

Introduction to the ADI Theory Test

If you’re looking to become an Approved Driving Instructor (ADI) in the UK, passing the ADI theory test is one of the first hurdles you’ll face. This essential step ensures that aspiring instructors don’t just know how to drive but also understand the rules of the road, safe teaching practices, and hazard perception at an advanced level.

The ADI theory test is more challenging than the learner driver theory test because it evaluates knowledge required for teaching, not just driving. In this guide, we’ll break down everything you need to know — from the structure of the test to expert preparation strategies — so you can walk into your test centre with confidence.

What Is the ADI Theory Test?

The ADI theory test is a government-administered assessment for those training to become Approved Driving Instructors in the UK. It’s part of the three-stage ADI qualification process, consisting of:

1. Part 1: ADI Theory Test (knowledge and hazard perception)
2. Part 2: Driving Ability Test
3. Part 3: Instructional Ability Test

Passing the theory test proves you have the depth of knowledge and hazard awareness required to teach others to drive safely.

Why the ADI Theory Test Matters for Driving Instructors

Unlike learner drivers, instructors must understand not only how to drive but also how to explain rules and best practices clearly to others. A strong grasp of theory ensures instructors can answer student questions confidently and keep learners safe on the road.

By passing this test, you demonstrate:

• Knowledge of the Highway Code
• Understanding of teaching methods
• Awareness of risk management
• The ability to spot hazards early

Who Needs to Take the ADI Theory Test?

The test is mandatory for anyone pursuing a career as a UK Approved Driving Instructor. If you’ve only passed the standard learner theory test, you’ll need to sit the ADI version because it’s more advanced and tailored for instructors.

ADI Theory Test Structure and Format

The ADI theory test is split into two key sections:

1. Multiple-choice questions
2. Hazard perception test

You must pass both sections in the same sitting to move forward in your ADI qualification journey.
