About the tests and requirements

The knowledge test takes place online. You will have a maximum of two hours to complete it.

The test will be invigilated. To complete the online invigilation tests, please ensure the below IT requirements are met:

• a laptop/computer with 4GB of available memory as the app will not work on phones, chrome books, or ipads/tablets
• we recommend that candidates source a non-touchscreen device for their exams

You must show your DVLA photocard licence when you take the tests. If you do not, you will not be able to take the session and you’ll have to pay the necessary fees again.

Please be aware, you will be asked to show the invigilator the room where you will be completing your test and also show the desk area to ensure you do not have notes, phones and so on. 

You can take the test a maximum of three times. We will reject your application if you do not pass on the third attempt. You must then wait six months from the date of your third attempt before registering to retake the test.

If you do not complete the knowledge test within 12 months of applying for a licence, we will remove your details from our system. We will do this even if you have not attempted the tests three times.
