What one sitting of the full set proves
A mock test is the same length as the real sitting, run in one go, with nothing looked up and the result held back until the end. That last part is what makes it useful: you find out whether you can hold the whole set together without checking anything, which is the only condition the real test offers. A practice test lets you check as you go, so it teaches. A mock only measures. The test being rehearsed is the Heavy Vehicle Knowledge Test, 45 questions on road rules and road safety for your licence class, set by Transport for NSW. It is computer based and booked online through myRTA or at a service centre, and a test fee is payable on each attempt, so check the current amount before you book.
Sitting a truck mock the way the real one runs
Treat every mock as if it were the booked one. Clear the desk, put the phone out of reach, and run the whole set in a single sitting without looking anything up, because a mock you pause is only a practice test with a different name. Sit it at the time of day you have booked the real test for, since concentration at nine in the morning is not the same as concentration at four in the afternoon. Mark it the moment you finish and read the reason behind every wrong answer before you open the next one. Then leave a day. Mocks sat back to back blur into each other, and the gap is what turns a miss into something you remember.
- 1
Clear the desk first
Nothing to hand, nothing open, and nobody to ask.
- 2
Run the whole set without stopping
No pausing part way and no looking a rule up.
- 3
Sit it at your booked time of day
Tired at four in the afternoon is a different driver to fresh at nine.
- 4
Go through every wrong answer
Read the reason before you open the next mock.
- 5
Wait a day before the next one
Back-to-back mocks blur together and teach less.
The eight mocks, and the order to sit them in
The eight truck mocks are numbered 1 to 8, and each one carries 45 questions drawn from the same material as the real test. They are free.
Start at Mock Test 1 and work up. Later numbers are not harder; they simply ask things you have not seen, which is the reason there are eight of them rather than one you re-sit. If the same subject keeps appearing in your misses, stop and work that subject at truck practice before you open the next mock.
The mark shown against each mock here is our own setting for your practice, not an official pass mark. What matters is the pattern: a clean mock, then another clean mock. If you would rather build up to the full length first, the practice tests at warm up on a practice test are the gentler way in.

Rigid or combination: the version your class sits
The heavy vehicle knowledge test comes in two versions, and your licence class decides which one you sit. LR, MR and HR sit the heavy vehicle rigid version. HC and MC sit the heavy vehicle combination version. Transport for NSW also publishes an official practice set for the rigid classes, holding 343 questions across its general knowledge, road safety and traffic signs sections, which is worth working through alongside the mocks here.
The classes describe the vehicle. LR covers trucks and buses up to 8 tonnes GVM, with a trailer up to 9 tonnes. MR covers vehicles over 8 tonnes with two axles. HR covers vehicles over 8 tonnes with three or more axles, including bendy buses. HC covers articulated vehicles of three or more axles, or a rigid truck with a trailer over 9 tonnes. MC covers B doubles and road trains.
What you must already hold differs too. LR and MR each need a class C licence, and not a learner licence, held for a year or more. HR needs a class C licence held for two years or more. HC needs an MR or HR licence held for a year or more. MC needs an HR or HC licence held for at least a year, plus the Heavy Vehicle Competency Based Assessment and a medical assessment. All of that is set out by Transport for NSW.
Six days of mocks before you book
Eight mocks fit comfortably into six days if you pair them with subject work rather than sitting them back to back. The shape below starts with one mock a day while the misses are still plentiful, puts a reading day in the middle, and finishes with two a day once the length has stopped being the hard part. Adjust it to your own week, but keep the reading day, and keep the last two mocks together, because sitting two in a row is the closest thing to the real pressure you can arrange at home.
- 1
Day one: Mock 1, then the subjects it found
Sit Mock Test 1, then work every subject it caught at truck practice.
- 2
Day two: Mock 2, then load restraint
A second mock, then the Load Restraint Guide pages and that subject set.
- 3
Day three: reading only, no mock
The Heavy Vehicle Driver Handbook, plus your two weakest subjects.
- 4
Day four: Mocks 3 and 4
Two sittings with a break between them. Read every miss.
- 5
Day five: Mocks 5 and 6
Two more. The length should feel ordinary by now.
- 6
Day six: Mocks 7 and 8, then book
The last two back to back. If both come back clean, book the test.
After the mocks: the HVCBA and the driving test
When two mocks in a row come back clean, the knowledge test is the part you are ready for. Passing it opens the next step rather than the licence: an eyesight test, then either the Heavy Vehicle Competency Based Assessment with an accredited provider or the heavy vehicle driving test. Class MC also needs a medical assessment. Transport for NSW sets out that order.
If a subject is still catching you, the subject sets at truck practice are where to work it, and the practice tests at warm up on a practice test are where to rebuild the full length.
These mocks are built on the NSW bank. If you will sit the test elsewhere, your own road authority sets the booking and the fee, so check there before you rely on anything here. For the Northern Territory, start at our Northern Territory page. Hazard perception clips are a separate test, at the hazard clip app.
