If your licence is only for automatic cars, you can upgrade it by passing a driving test in a manual car.
Learning to drive a manual car
You can start learning to drive a manual car at any time. You don’t need to apply for another provisional licence.
You must follow all the usual rules when you’re learning to drive in a manual car. This includes displaying L plates.
Book a driving test
You do not need to take a theory test to upgrade your licence.
You have to book a driving test by phone with the Driver and Vehicle Standards Agency (DVSA). You cannot book it online.
Taking the driving test
The driving test works in the same way for a manual car as it does an automatic.
You can continue driving an automatic car if you fail your driving test in a manual car.
