The official test

What is the Theory Test (CTT)?

Western Australia calls it the Computerised Theory Test, or CTT — the road-rules test you must pass to get a learner's permit, unless you completed Keys4Life at school in the last 2 years. You will see it called the learners test, the theory test and the road rules theory test as well; they are all the same exam, sat on a computer at a Department of Transport and Major Infrastructure centre.

The test itself

Thirty multiple-choice questions on the WA road rules, and you need at least 24 of them — 80% — to pass. You sit it on a computer at a DTMI service centre or a regional agent, and you can sit it the same day you apply for your learner's permit. A pass result stays valid for 5 years. You cannot use a phone or any other device during the test, and you cannot refer to the Drive Safe handbook while you are sitting it. If you completed Keys4Life at school in the last 2 years, you do not need to sit or pay for it: show your Keys4Life certificate when you apply for your learner's permit.

Practising for it

Every question comes out of Drive Safe, the Department's own handbook for Western Australian road users, which explains the rules in the Road Traffic Code 2000. Transport WA also publishes its own Road rules theory test quiz — worth doing alongside this one, because seeing the same rule asked two different ways is what proves you actually know it rather than having memorised a phrasing.

Official sources

Passing it

How do you pass the WA theory test?

80% is six wrong answers, not sixteen

Twenty-four out of thirty sounds generous until you are sitting there. Practise until you are clearing 90% consistently on questions you have not just seen, so a couple of unfamiliar wordings on the day cannot sink you.

Drive Safe is the actual syllabus

The questions are drawn from the handbook, which sets out the major rules from the Road Traffic Code 2000. Practice tests show you which rules you do not know yet; the handbook is what teaches them. Use them in that order.

You cannot take anything in with you

No phone, no device, no Drive Safe handbook during the test. That sounds obvious, but it means the rules you half-remember are the ones that will cost you — there is nothing to check against.

The theory test is only the first of two

Passing the CTT gets you the learner's permit. The hazard perception test is a separate computer test you sit later, and you cannot go for your P plates without it. Plan for both rather than being surprised by the second.

The road ahead

Your path to P plates in Western Australia

  1. Be at least 16 years old

    The minimum age for a learner licence in Western Australia.

  2. Pass the Theory Test (CTT) You are here

    That's what this practice test is for — keep going until you consistently score 90%+.

  3. Log 50 supervised hours, including 5 at night

    Mix of day and night, quiet streets to highways — professional lessons build good habits early.

  4. Pass your driving test → P plates

    Rules are set by the Department of Transport and Major Infrastructure (DTMI) — always check current requirements before you book.

The Hazard Perception Test (HPT) in Western Australia, explained

The theory test on this page gets you your learner's permit. The Hazard Perception Test is the second computer test in the Western Australian sequence, and you cannot progress towards your P plates without it.

What the HPT actually tests

Judgment and timing rather than rule knowledge. It shows you a range of traffic situations and assesses your ability to read road hazards and make safe decisions — during the test you click to indicate when it is safe to begin a manoeuvre, or to take action to reduce the risk of a crash.

When you can sit it

Once you have held your learner's permit for at least six months and you are at least 16 years and six months old. Bring your learner's permit, or primary and secondary identification.

Where you sit it

At any DTMI service centre or regional agent. You do not need an appointment at a metropolitan centre, but you may need to call ahead at a regional one, and every test has to start before 3:45pm (4:45pm at Joondalup) — so it is not something to attempt late in the day.

If you don't pass

You resit on another day rather than immediately, at a lower resit fee. A pass is valid for 5 years, the same as the theory test.

Straight answers

WA theory test questions, answered

How many questions is the WA theory test and what is the pass mark?
Thirty multiple-choice questions, and you need at least 24 correct — 80% — to pass.
Is the WA theory test the same thing as a DKT?
No. Western Australia does not have a Driver Knowledge Test — that is the New South Wales name. WA's test is the Computerised Theory Test (CTT), and a site advertising a "WA DKT" has copied its content from another state.
Can I sit the theory test online?
No. You sit the CTT on a computer at a Department of Transport and Major Infrastructure service centre or a regional agent. You can sit it the same day you apply for your learner's permit.
How long does a pass last?
A theory test pass result is valid for 5 years, so passing early does not go to waste if it takes you a while to get on the road.
Can I use the Drive Safe handbook during the test?
No. You cannot use a mobile phone or any other device, and you cannot refer to the Drive Safe handbook while sitting the test.
What is the hazard perception test and do I need it?
Yes, eventually. The HPT is a separate computer-based test of your ability to judge hazards, sat once you have held your learner's permit for at least six months and are at least 16 years and six months old. You need it to progress towards your P plates, not to get the learner's permit itself.
Is this practice test the real thing?
No. This is free unofficial practice written from Drive Safe, the Department's own handbook, with an explanation and a source on every answer. It does not book or replace the CTT — its job is to find the rules you have not learned yet before you pay to sit the real one.
