Western Australia Road Rules

Where WA road rules come from — the law and the handbook

In Western Australia the road rules are not a set of tips — they are law. They sit in the Road Traffic Code 2000, and the Department of Transport (DoT) translates that legislation into the plain-English Drive Safe: A handbook for Western Australian road users. Every question in the WA learner’s theory test is drawn from that handbook, and every fine an officer issues traces back to the Code.

This matters for two reasons. First, WA rules are broadly aligned with the Australian Road Rules used across the country, but the state sets its own penalties, demerit-point values and licensing steps — so a rule you learned interstate may carry a different consequence here. Second, rules and penalties change. This page teaches the structure and the reasoning so it stays useful, but for the current dollar figure, point value or age you should always confirm with the Department of Transport, the authority that publishes the official numbers. We are an independent study resource and are not affiliated with the Department of Transport or any government body.

If you are learning the visual side of the rules — regulatory, warning and guide signs — pair this page with our road signs guide, and return to the road rules hub to compare WA against the other states.

Speed limits in Western Australia

WA speed limits work on a system of default limits and signed limits. A signed limit always wins — if a sign shows a number, that is the maximum, full stop. Where there is no sign, a default applies based on the type of area you are in.

• Built-up areas (streets with buildings, street lighting or frequent access) default to a lower urban limit — commonly 50 km/h — unless signs say otherwise.
• Open rural roads carry a much higher default, with 110 km/h posted on many highways.
• School zones drop to a reduced limit (commonly 40 km/h) during the posted times on school days. These operate at specific hours, not around the clock, so read the times on the sign.
• Roadworks and emergencies impose temporary limits — and in WA you must also slow right down when passing stationary emergency, tow or breakdown vehicles displaying flashing lights.

The limit is a maximum for ideal conditions, not a target. Rain, gravel, poor light, wildlife on country roads and heavy traffic all mean the safe speed is lower than the sign. Because posted limits vary street by street, treat every number as something to read and confirm on the day rather than assume.

Give way, roundabouts and intersections

Most crashes at intersections come down to one thing: getting the give-way order wrong. WA follows the standard Australian give-way logic, and the theory test leans on it heavily.

• Give way signs and lines mean you must slow, and stop if needed, until the way is clear. A Stop sign means you must come to a complete halt behind the line every time, even if the road looks empty.
• Turning across traffic: when you are turning right at a cross-intersection and an oncoming car is going straight or turning left, you give way to them.
• The T-intersection rule: traffic on the road that ends (the stem of the T) gives way to traffic on the continuing road (the top of the T).
• Roundabouts: signal your intention, give way to any vehicle already on the roundabout, and signal left as you leave. Approaching, you indicate right for a right turn, left for a left turn, and no early indication when going straight ahead.
• Uncontrolled intersections (no signs, no lights) still need care — give way to the right where the standard rules leave it ambiguous, and never assume the other driver knows the rule.

Pedestrians, cyclists and give-way order at slip lanes and shared zones all appear in the test. Working through scenario questions is the fastest way to make these automatic — you can drill them in our free WA practice questions.

Demerit points and fines — how the WA system works

WA runs a demerit points scheme alongside on-the-spot fines. Understanding the mechanism matters more than memorising any single figure, because the figures change.

How it works: most traffic offences carry both a fine and a number of demerit points. The points attach to your driving record and accumulate over a rolling period. When your total reaches the threshold set for your licence type, your licence is suspended — and newer drivers on a provisional licence sit under tighter limits than a full-licence holder. This is why a run of “minor” offences can end your driving just as surely as one serious one.

Double demerits: WA is well known for running double-demerit periods over major public holidays and long weekends. During these windows, points for speeding, seatbelt, mobile-phone and drink-driving offences are doubled — so an offence that normally chips away at your record can suddenly take a large bite. Always assume a long weekend is a double-demerit period unless you have confirmed otherwise.

For the exact demerit-point value of a specific offence, the current fine amounts, the suspension thresholds and the double-demerit calendar, check the Department of Transport’s official penalty schedule — we deliberately do not print those numbers here because they are updated by the authority and printing a stale figure would mislead you.

The high-penalty offences: phones, seatbelts, alcohol and drugs

A handful of offences carry the heaviest combination of fines, demerit points and, in the worst cases, criminal charges. These are the rules WA enforces hardest.

• Mobile phones: WA has strict handheld-phone laws and now uses automated detection cameras that photograph drivers using a phone. Holding or touching a phone to text, scroll or call while driving — including while stopped at lights — is an offence. The penalties are among the steepest of the everyday offences.
• Seatbelts: every occupant must be properly restrained, and as the driver you are responsible for passengers under 16 being correctly secured. Children must use an approved restraint suited to their age and size.
• Drink driving: the general blood-alcohol limit for full-licence holders is under 0.05. Learner and provisional (novice) drivers must maintain a zero blood-alcohol reading — 0.00. Penalties escalate sharply with the reading.
• Drug driving: driving with the presence of illicit drugs is an offence tested by roadside saliva screening, separate from alcohol.

Because the fines and disqualification periods for these offences are severe and can change, confirm the current figures with the Department of Transport rather than relying on what a mate told you.

The WA licensing pathway and the theory test

The road rules on this page are exactly what you are examined on to earn a WA licence, so it helps to see where the theory test sits in the journey.

The car pathway runs through a Learner’s Permit, a period of supervised driving with a logbook, a Practical Driving Assessment (PDA), a Hazard Perception Test (HPT), and then a provisional (P) licence before a full licence. To get the learner’s permit you must pass the Learner’s Permit Theory Test, which for a car is a 30-question assessment on the road rules, signs and safe-driving knowledge in the Drive Safe handbook.

For the minimum ages at each stage, the required supervised hours, licence-class codes and the fees for tests and permits, check the Department of Transport — those specifics are set by the authority and we will not guess at them. The hazard-perception stage tests something the theory test cannot: your ability to spot and respond to developing risks in real traffic. If that is your next step, our Hazard Perception course is built for it. Planning to ride as well? See the structure of the rider pathway on our motorcycle guide, and compare requirements across states on the tests by state page.

Practise WA road rules the free way

Reading the rules gets you part of the way; answering questions the way the test asks them is what makes the knowledge stick. Every part of our WA practice is completely free — the give-way scenarios, speed-limit questions, sign recognition and demerit-awareness questions are all drawn from the same rules covered above, and you can repeat them as many times as you like at no cost.

The only thing we sell is our Hazard Perception course, a one-time payment of A$9.90 — not a subscription, with nothing to cancel and a money-back guarantee if it isn’t right for you. It is optional; you can pass the WA theory test using the free practice alone.

Start with a mixed set to find your weak spots, then focus your revision where you drop marks. Open the free WA practice questions and work through a round today, and use the road rules hub to keep the picture straight across every state.
