How to Become a Driving Instructor: The Complete Training Process
Are you considering a career change and wondering how to become a driving instructor in the UK? The demand for qualified driving instructors is growing, and with flexible working hours, strong earning potential, and the chance to help others achieve a life-changing skill, it’s a rewarding career path.
This guide explains the full driving instructor training process, from eligibility requirements to passing your final test and registering as an Approved Driving Instructor (ADI).
Who Can Become a Driving Instructor?
Before starting your training, you’ll need to meet some basic requirements set by the DVSA (Driver and Vehicle Standards Agency):
Be at least 21 years old.
Hold a full UK or EU driving licence for at least three years.
Have fewer than six penalty points on your licence.
Pass a criminal record (DBS) check.
Step 1: Get an Enhanced DBS Check
Before you can start your journey to becoming a driving instructor, you must apply for an enhanced DBS (Disclosure and Barring Service) check specifically for driving instructors.
What is it?
The enhanced DBS check ensures that you are legally suitable to work with members of the public, including young and vulnerable learners.
How to apply?
Apply through the official GOV.UK website using the designated link for ADI and PDI applicants.
You will receive an activation link via email to start your application.
Provide your proof of identity and personal details for verification.
Processing time: Usually takes 2–4 weeks, but it’s best to start this process early as you cannot progress to the next steps without a valid DBS certificate.
Tip: Do not use a standard DBS—only the enhanced version for driving instructors is accepted by the DVSA.
Step 2: Apply for Your PRN (Personal Reference Number)
Once your enhanced DBS check is complete, you can apply for your PRN (Personal Reference Number). This is your official DVSA registration number and is required to book your ADI tests.
How to apply?
Submit your application on the GOV.UK website for becoming a driving instructor.
You’ll need your enhanced DBS certificate details, full driving licence, and some personal information.
Once approved, your PRN will be sent to you and will be used throughout your training and career as a driving instructor.
Why is it important?
Without your PRN, you cannot book your Part 1 theory test or continue with the qualification process.
The Three-Part ADI Qualification Process
To become an Approved Driving Instructor, you must pass three tests, known as ADI Part 1, Part 2, and Part 3.
Part 1: Theory and Hazard Perception Test
The first step to becoming a driving instructor is passing the ADI Part 1 theory and hazard perception test. This stage ensures you have the knowledge and awareness required to teach learners safely and confidently.
What’s involved?
A multiple-choice theory test covering the Highway Code, road safety, driving techniques, instructional knowledge, and rules of the road.
A hazard perception section where you watch a series of video clips and identify developing hazards.
Part 2: Driving Ability Test
The second stage in your journey to becoming a driving instructor is the ADI Part 2 driving ability test. This is designed to ensure you can drive to a very high and consistent standard—above the level of a normal driving test.
What’s involved?
A practical driving test lasting around one hour.
Includes an eyesight check, vehicle safety questions, manoeuvres, independent driving, and a variety of road types.
You will be assessed on control, planning, awareness, eco-safe driving, and overall competence.
How to prepare effectively?
Many people require around 8 lessons of 2 hours each with a driving instructor who is familiar with the Part 2 test.
These lessons help you meet the higher standard expected and focus on the specific skills that will be assessed.
This preparation also helps develop the right awareness and forward planning skills that you’ll later need to pass on to your learners.
Pass mark:
No more than six driving faults.
No serious or dangerous faults are permitted.
Tip to succeed:
Regular practice with a qualified trainer ensures you learn the standard expected for driving instructors, not just everyday drivers.
What resources can you use to prepare?
DVSA-approved books and study guides specifically for driving instructors.
Official DVSA apps designed to help you practice both the theory questions and hazard perception clips.
Online mock tests and practice papers, many of which replicate the real test environment.
Example hazard perception videos that allow you to practise spotting potential hazards in various driving scenarios.
How long should you revise?
Many trainees spend 4–6 weeks preparing for this stage, depending on their availability. Regular, short study sessions often lead to better retention than cramming.
Tips to pass first time:
Familiarise yourself with the latest Highway Code updates.
Practise hazard perception clips until you can confidently spot developing hazards early.
Take multiple mock tests to track your progress and identify weak areas.
Passing this stage sets the foundation for the rest of your training and allows you to move on to Part 2: Driving Ability Test.
Part 3: Instructional Ability Test
Most people, after passing ADI Part 1 and ADI Part 2, choose to apply for a PDI (Potential Driving Instructor) trainee licence so they can earn while they learn and build real lesson experience before attempting ADI Part 3. If you’re unsure whether to go PDI first, see our PDI vs ADI guide for a full comparison.
Step 1 — Complete 40 hours of training (before your PDI licence): To be eligible for a PDI trainee licence (the pink badge), you must first complete 40 hours of instructor training with an approved trainer. This is the “how to be a driving instructor” phase and it prepares you for the teaching standards assessed in Part 3. Typical modules include:
Client-centred teaching methods and coaching conversation
Lesson planning, goal setting, and reflective logs
Risk management and shared responsibility in the car
Fault identification, analysis, and remedial techniques
Route planning for structured lessons and progressive difficulty
Using visual aids, briefings, and demonstrations effectively
Step 2 — Become a PDI and practise for Part 3: Once the initial 40 hours are done, you can apply for your PDI trainee licence and start giving paid lessons to real learners (sponsored by a driving school). This lets you earn while you train, build confidence, and gather the real-world experience you’ll need for Part 3.
Step 3 — Complete an additional 20 hours before the test: Before you take the ADI Part 3 test, you must complete a further 20 hours of training on top of the initial 40. This advanced phase typically focuses on:
Observed lessons with targeted feedback from your trainer
Fine-tuning risk management and coaching techniques
Handling different pupil abilities and adapting teaching style
Structured mock Part 3 assessments to exam standard
What the ADI Part 3 Test Involves
The ADI Part 3 (Instructional Ability) test is an observed, real lesson with one of your pupils. An examiner sits in on your session (usually around 45 minutes) and evaluates how effectively and safely you teach.
What the examiner assesses:
Lesson Planning: Clear goals, appropriate level for the pupil, logical structure, and measurable outcomes.
Risk Management: Clear roles and responsibilities, timely interventions, and a safe learning environment.
Teaching & Learning Strategies: Coaching approach, feedback quality, communication, adapting methods to pupil needs, and encouraging reflection.
On the day, you’ll need:
A suitable, roadworthy car (dual controls strongly recommended), L-plates, and an extra interior mirror for the examiner.
A learner who fits the lesson aim (not a complete novice).
A planned lesson with aims you can explain and review at the end.
Common reasons people struggle:
Vague goals or a lesson that’s too easy/too hard for the pupil.
Reacting late to developing risks or not agreeing clear risk-sharing.
Talking too much / not checking understanding / little pupil involvement.
No measurable progress or weak recap and reflection.
Tips to maximise your score:
Agree goals up front and keep checking progress against them.
Use brief, focused coaching questions and let the pupil think out loud.
Anticipate hazards early; share and manage risk explicitly.
Use short demos/visuals; keep driving time high and feedback targeted.
Wrap up with a concise review: what went well, what to improve, next steps.
How Long Does It Take to Become a Driving Instructor?
On average, the full process takes 6–12 months, depending on:
How quickly you pass each test.
Your availability for training and practice.
Whether you choose to become a PDI or go straight to ADI.
