UK lorry & bus theory test (Driver CPC Part 1)
Last updated
The UK lorry (LGV) and bus (PCV) theory test is officially the Driver CPC Part 1, split into two parts that are booked and paid for separately: Part 1a (multiple-choice) is 100 questions in 1 hour 55 minutes with a pass mark of 85 out of 100, and Part 1b (hazard perception) is 19 clips with 20 scored developing hazards and a pass mark of 67 out of 100. Fees: £26 for Part 1a + £11 for Part 1b . Both parts must be passed within 2 years of each other.
You have 1 hour and 55 minutes to answer 100 multiple-choice questions … The pass mark for this part is 85 out of 100.
Structure and pass marks
| Part | Format | Pass mark | Fee |
|---|---|---|---|
| Part 1a — multiple-choice | 100 questions in 1 h 55 min | 85 / 100 | £26 |
| Part 1b — hazard perception | 19 clips, 20 scored developing hazards (1 clip has 2) | 67 / 100 | £11 |
Two-year window between Part 1a and 1b
Part 1a and Part 1b are booked and sat separately — you can take them on different days. Both must be passed within 2 years of each other for the Part 1 theory certificate to be issued. The certificate then lasts 2 years from the date of the later pass, by which time you must have passed Part 2 (case studies) and Part 3 (practical driving) for full Driver CPC.
Driver CPC context
The Driver Certificate of Professional Competence (Driver CPC) is required for anyone driving a lorry, bus or coach for a living in Great Britain. Part 1 (the theory test described here) is followed by Part 2 (case studies, £23) and Part 3 (practical driving). The 2026 CPR/AED theory test questions announced for car and motorcycle tests have not yet been confirmed for lorry/bus theory — gov.uk states the questions will be added to other test types later, without a specific date.
