1. The New Drivers Act and the 6-Point Rule
Special rules apply for a period of two years from the date of passing their first driving test, to drivers and motorcyclists from the UK, EU/EEA, the Isle of Man, the Channel Islands or Gibraltar who passed their first driving test in any of those countries. They also apply to drivers from other foreign countries who have to pass a UK driving test to gain a UK licence, in which case the UK driving test is treated as their first driving test. Furthermore, they apply to drivers from other foreign countries who exchanged their licence for a UK licence without needing a test, and subsequently passed a UK driving test to drive another type of vehicle; the UK driving test is treated as their first driving test.
Where a person subject to these special rules accumulates 6 or more penalty points before the end of the 2-year period, including any points acquired before passing the test, their licence will be revoked automatically. This applies even if they pay for offences by fixed penalty. Drivers in the first group (UK, EU/EEA etc.) who already have a full licence for one type of vehicle are not affected by the special rules if they later pass a test to drive another type of vehicle. Under the New Drivers Act, you will need to pass both the theory and practical tests again to get back your full licence. To regain the licence, you must reapply for a provisional licence and may drive only as a learner until you pass a further driving test. You can apply for a new one at any time by getting form D1 from the Post Office and sending it with the fee to the address on the form.
2. Provisional Licence Holders
You must retake both parts of your driving test if your provisional licence is cancelled after you have passed your test, but you have not sent off for your full licence yet. You can use your current provisional licence to take the tests.
3. Upgrading an Automatic Car Licence to a Manual One
If your licence is only for automatic cars, you can upgrade it by passing a driving test in a manual car. You can start learning to drive a manual car at any time, and you do not need to apply for another provisional licence. You must follow all the usual rules when you are learning to drive in a manual car, which includes displaying L plates. 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) because you cannot book it online. You need a debit or credit card to pay for the cost of the test and to choose which driving test centre you want to take the test at. 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.

4. Upgrading Other Licences Without a Theory Test
You do not need to take a theory test before you book a driving test to upgrade from an automatic car licence to a manual car licence, or from category A1 (small motorcycle) to category A2 (medium motorcycle) if you have had the licence for at least 2 years. You also do not need a theory test to upgrade from category C1 (medium vehicles) to category C (large vehicles) unless you got your C1 entitlement from passing a car driving test, or from category D1 (minibus) to category D (bus). Additionally, you do not need a theory test to upgrade any licence to be able to tow a trailer, or before you book a taxi driving test or tractor driving test.
