1What is the default speed limit in a built-up area in Western Australia when no speed sign is posted?
A.60 km/h
B.50 km/h
C.70 km/h
D.40 km/h
Explanation: In Western Australia, the default speed limit in a built-up area is 50 km/h unless a different limit is displayed on a speed sign. A built-up area is generally a road with street lighting, houses, or other development on both sides. Always look for posted signs that may set a lower or higher limit.
2What is the maximum speed limit on most highways and open roads in Western Australia?
A.100 km/h
B.130 km/h
C.110 km/h
D.120 km/h
Explanation: Posted speed limits in Western Australia are capped at 110 km/h on highways and rural roads. You must never exceed the limit shown on the speed sign. Driving too slowly on a freeway is also an offence — you must not travel more than 20 km/h below the posted limit unless conditions make it unsafe to do so.
3What speed limit applies in a WA school zone when the overhead flashing lights are active?
A.50 km/h
B.60 km/h
C.30 km/h
D.40 km/h
Explanation: When the flashing speed-limit signs at a WA school zone are operating, a 40 km/h limit applies. These signs operate during gazetted school days at set times. When the lights are not flashing, the normal posted speed limit for that road applies. Every school in WA has at least one flashing sign, most of which are solar powered.
4A full-licence holder in WA must remain below which blood alcohol concentration (BAC) limit while driving?
A.0.08
B.0.00
C.0.05
D.0.02
Explanation: Full (open) licence holders in Western Australia must have a BAC below 0.05 at all times while driving. If caught with a BAC of 0.05 or above, a driver may be infringed or required to appear in court. A BAC of 0.08 or above triggers immediate licence disqualification.
5What BAC level must learner (L-plate) and provisional (P-plate) drivers maintain in Western Australia?
A.Below 0.05
B.Below 0.02
C.Exactly 0.00
D.Below 0.08
Explanation: In WA, novice drivers — including those on a learner's permit or a provisional licence — must have a blood alcohol concentration of exactly 0.00 at all times when driving or riding. Even a small amount of alcohol is illegal for these drivers. This zero-BAC rule applies regardless of the time of day or road type.
6You approach an uncontrolled intersection (no signs or lights) at the same time as a vehicle on your right. What must you do?
A.Sound your horn and proceed
B.Give way to the vehicle on your right
C.Proceed because you are on the main road
D.Flash your headlights and continue
Explanation: At uncontrolled intersections in WA (no traffic lights, stop signs, or give-way signs), you must give way to any vehicle approaching from your right. This is the basic give-way-to-the-right rule. If the other vehicle is on your right at the same time, they have priority and you must wait.
7When entering a roundabout in Western Australia, you must give way to:
A.Vehicles on your left already in the roundabout
B.Vehicles already circulating in the roundabout
C.Vehicles entering from your right
D.No one — the first vehicle in has priority
Explanation: WA road rules require drivers entering a roundabout to give way to all vehicles already travelling in the roundabout, regardless of which direction they are coming from. You must not enter until it is safe to do so. Failure to give way to vehicles on a roundabout carries a fine and 3 demerit points.
8What is the recommended following distance behind the vehicle in front when driving in normal conditions in WA?
A.1 second
B.4 seconds
C.2 seconds
D.3 seconds
Explanation: Western Australia recommends a minimum following distance of 2 seconds behind the vehicle in front in dry conditions. You can measure this by watching the vehicle ahead pass a fixed point, then counting two seconds before your vehicle reaches the same point. In wet or slippery conditions, or behind a heavily loaded truck, the safe following distance should be increased to 3 or 4 seconds.
9When must you keep to the left lane on a multi-lane road in WA?
A.Only on freeways
B.On any road with more than one lane in your direction
C.On roads with a speed limit of 90 km/h or more, unless overtaking
D.Whenever there is a vehicle behind you
Explanation: On multi-lane roads with a posted speed limit of 90 km/h or more, drivers in WA must keep to the left lane unless overtaking or when directed otherwise by a sign. On roads with lower speed limits, you should still keep left where practical but are not legally required to unless signposted.
10You are driving at 60 km/h and want to pass a cyclist. What is the minimum passing clearance required in WA?
A.0.5 metres
B.2 metres
C.1.5 metres
D.1 metre
Explanation: In WA, when passing a cyclist travelling in the same direction on a road with a posted speed limit of 60 km/h or less, drivers must leave at least 1 metre of clearance. On roads with a speed limit above 60 km/h, the minimum clearance increases to 1.5 metres. This rule protects cyclists from dangerous close passes.

WA CTT Car Theory Test Study Tips from Top Performers

1Read the Drive Safe handbook cover to cover — every CTT question is drawn directly from it, so thorough reading is the most efficient preparation
2Memorise WA-specific numbers: 50 km/h built-up default, 110 km/h highway maximum, 40 km/h school zone, 0.05 BAC for full licence, zero BAC for L and P drivers
3Practise give-way rules at every intersection type — uncontrolled intersections (give way to right), roundabouts (give way to vehicles already in), and T-junctions (give way to through road)
4Learn the two-second following-distance rule and when to increase it (wet roads, towing, heavy vehicles), and know the cyclist passing clearance (1 m at 60 km/h or below, 1.5 m above)
5Aim to score consistently above 90% on practice tests before your real CTT, giving yourself a comfortable buffer above the 80% (24/30) pass mark

Frequently Asked Questions

How many questions are on the WA Computerised Theory Test for cars?

What score do I need to pass the WA CTT?

You must answer at least 24 of the 30 questions correctly, which equals 80%. If you score 23 or fewer correct, you fail. There is no partial credit — each question is right or wrong.

How much does the WA theory test cost?
