You can book your official practical driving test using the DVLA official practical test booking service. This service is available between 6am and 11.40pm.
Normally you will have passed your theory test first before booking your practical test.
To book online you will need your provisional driving licence number, an email address and debit or credit card.
If you have any problems booking online or have any special requirements at the test you can contact the DVSA booking support.
