The NSW Heavy Vehicle Knowledge Test has 45 questions. The official test is split into rigid and combination pathways; DrivePrep NSW provides independent Heavy Rigid and Heavy Combination practice.
What is the Heavy Vehicle Knowledge Test?
It is a computer-based test that must be passed before applying for a Heavy Vehicle Competency Based Assessment or a heavy vehicle driving test. The questions cover road rules and road safety related to the licence class.
Which heavy vehicle test do I need?
| Official pathway | Licence classes described by NSW |
|---|---|
| Heavy vehicle rigid | Light Rigid (LR), Medium Rigid (MR), or Heavy Rigid (HR) |
| Heavy vehicle combination | Heavy Combination (HC) or Multi Combination (MC) |
DrivePrep labels these practice pathways Heavy Rigid and Heavy Combination. Always confirm the test associated with the licence class you are applying for.
How can DrivePrep help?
- Practise the Heavy Rigid or Heavy Combination question bank.
- Work by category instead of repeating the same full test.
- Use a 45-question mock test to check your study progress.
- Review incorrect answers and bookmark questions to revisit.
What should I read before the test?
NSW says the information needed for the Heavy Vehicle Knowledge Test is found in the Heavy Vehicle Driver Handbook, Road User Handbook, and Load Restraint Guide. DrivePrep NSW is supplementary practice and does not replace those official resources.
What if I don't pass?
NSW says that, depending on availability, you may be able to re-sit the Heavy Vehicle Knowledge Test on the same day, or you can book to sit it another time. A test fee applies for each attempt. Use a failed mock test in DrivePrep NSW to identify which category — rigid or combination — needs another pass before you book a re-sit.
Is support available if English isn't your first language?
Yes. NSW offers the Heavy Vehicle Knowledge Test in 10 languages (English, Arabic, Chinese, Croatian, Greek, Korean, Serbian, Spanish, Turkish, and Vietnamese), plus interpreter services for other languages, audio versions, reading assistance, and the Driver Licensing Access Program for people who need extra help.
