CPC Part 1 Theory Test

Driver CPC Module 1 Theory Test

The driving theory test for lorries, buses, and coaches includes part one of the CPC. Part 1a and part 1b make up the first module of a Driver Certificate of Professional Competence.

CPC INITIAL QUALIFICATION PART 1: You must get your provisional licence first.

You can then book the theory test of the Driver Certificate of Professional Competence.

The theory test is actually made up of 2 separate parts. The two modules are 1a 'multiple choice questions' and 1b 'hazard perception'.

You will need to make a separate booking for each part. But, you can choose to take both tests on the same day if you prefer.

There is no specific ruling on which test you take first to get the theory test certificate. But, you must pass both of them within two (2) years of each other.

Licence for Driver CPC Theory Test

After you book the theory test you will need to take one of these driver licences with you:

Note: You may not have a photocard driving licence. In this case, take your paper driver's licence and a valid passport. Failing to have the right documents means they will cancel your test and you will lose the fee.
