When your trainee licence runs out
Your trainee licence lasts for 6 months. When it runs out you must stop being paid for giving driving lessons.
Getting another licence
You can apply for another trainee licence, but you’ll need to pay the fee again.
You can’t be paid for giving driving lessons when you don’t have a valid trainee licence.
You’re more likely to get another licence if you told DVSA you had stopped using the first, eg because of a period of illness.
It’s unlikely that you’ll get another licence just to give you more time to pass the approved driving instructor (ADI) part 3 test.
It’s unlikely you’ll get another trainee licence if you already have a full-time job and you can only practise using your licence in the evenings and at weekends.
You can appeal to the transport tribunal if you’re not given another licence.
