PDI to ADI: how the trainee licence works

The gap between passing ADI part 2 and passing part 3 is where most people qualifying as a driving instructor run out of money. A trainee licence — the pink badge — closes it by letting you charge for lessons before you are fully qualified.

It is also the stage with the most rules and the least written about it. Here is what the licence does, what it costs you in obligations, and the two traps that end one early.

What a trainee licence is

A trainee driving instructor licence lasts 6 months and costs £140. It exists so you can “get experience instructing pupils to drive” and “charge for lessons to cover the cost of things like your insurance and vehicle costs” while you prepare for part 3.

The important word is trainee. You are not an ADI, you cannot present yourself as one, and you are attached to a training establishment rather than running your own school.

Who can apply

Four conditions, all of them checkable before you spend the £140. You must:

• have passed the ADI part 1 test in the last 2 years
• have passed the ADI part 2 test
• have had at least 40 hours of training from a qualified ADI in providing driving instruction, at least 10 of which were in a car, recorded on the ADI 21T declaration form
• be eligible to take the ADI part 3 test

If DVSA refuses you a licence, you can appeal to the General Regulatory Chamber. Northern Ireland runs a different process.

The choice you cannot unmake

When you apply you pick one of two routes, and gov.uk is blunt about it: “You can only choose one option and you cannot change to the other after you’ve made your decision.”

Option 1 — supervision

Your sponsoring ADI supervises 20% of all the lessons you give. You keep a record of the hours you teach and the hours you are supervised, on form ADI 21S, signed by both of you, and you send it to DVSA when the licence runs out.

This suits you if you are teaching a lot: 20% of a full diary is a lot of supervised hours, but it is real in-car feedback on real learners, which is what part 3 assesses.

Option 2 — extra training

At least 20 hours of extra training, completed “within the next 3 months and before you book the ADI part 3 test”, with “at least 25% of the training” practical in-car work. It goes on the instructor training declaration form, which you send to DVSA as soon as it is done — and if you do not send it, “DVSA can take your trainee licence away”.

This suits you if your diary will be light, or if you would rather concentrate the development into a block than spread it over six months.

Talk it through with your sponsoring ADI before you commit. The choice is usually made in ninety seconds on an application form and then lived with for six months.

The rules while you hold it

Four of them, and three are the ones people trip over.

Display it. The licence goes “on the nearside edge of the front windscreen of your car while you give driving lessons”.

Stay with your establishment. The licence carries the name and address of your training establishment, and “you can only give instruction from there, so you cannot work independently, such as by setting up your own school”. Moving school means applying for a new licence — there is no fee, and you can keep teaching while you wait, but you must send the old one back.

Advertise honestly. This one catches nearly everyone. You must describe yourself as a “trainee driving instructor” — gov.uk specifically says “do not use the term ‘potential driving instructor’ or ‘PDI’, as these are not widely understood by the public”. You must name your training establishment, and you may only give their contact details, not your own. Your establishment has to follow the same rules when it advertises on your behalf.

Be a fit and proper person, and get the supervision or training you signed up for while the licence is still valid.

How a trainee licence ends early

The registrar can take it away before the six months are up if you break any of the rules, if it was issued by mistake or gained by fraud, or if you fail 3 attempts at the ADI part 3 test.

That third one is the hard stop. Three part 3 failures against one part 1 pass and you are back to the beginning of the whole process, part 1 included. That is why the supervision or training you chose above matters more than the licence itself.

If you stop using the licence — a long illness, say — send it back to DVSA. You will not get a refund, but DVSA records that you did not have full use of it, and that counts in your favour if you ask for another.

Two practical points

Keep your own records from day one. Whichever route you chose, you are the one who has to produce hours to DVSA at the end. Reconstructing six months of lesson and supervision hours from memory and bank statements is the avoidable version of this. Log each lesson as it happens.

The learners you teach now are your first learners later. Recording what each learner has covered, against the syllabus the test is graded on, means that when the green badge arrives you are continuing a lesson plan.

That is the part Passdesk is for: a diary, payments, and progress recorded against the UK test, from your first trainee lesson through to running your own school. See what it costs, or read how to start a driving school for the steps either side of this one.
