South Australia Road Rules

Where South Australia's road rules come from

South Australia doesn't write road rules from scratch. Like every state and territory, SA adopts the national Australian Road Rules — a model set of rules that keeps driving broadly consistent across the country — and gives them legal force through its own Road Traffic Act and associated regulations. The rules are administered by the Department for Infrastructure and Transport (DIT), and enforced by South Australia Police (SAPOL).

What this means in practice: most of what you already know about driving in Australia — keep left unless overtaking, give way to your right at an uncontrolled intersection, stop at a red light — holds true in SA. But some limits, penalties and licence conditions are set locally, so a rule you learned interstate isn't automatically identical here. When the detail matters — an exact speed limit, a fine, a demerit threshold — the SA source is DIT (mylicence.sa.gov.au) and the official South Australian Driver's Handbook. This page teaches the structure so you understand why the rules work the way they do; always confirm the current figures with DIT before you rely on them.

Test yourself

How the rules change across the SA licence pathway

South Australia uses a graduated licensing system. You don't just pass one test and drive freely — you move through stages, and the road rules tighten or loosen depending on which stage you're in. Understanding the pathway is half of understanding the rules.

• Learner's Permit (L): you must be supervised by a fully licensed driver at all times, display L plates, and log supervised driving hours. Learners have the strictest conditions — a zero blood-alcohol limit, no mobile phone use at all (not even hands-free), and lower demerit tolerance.
• Provisional P1 and P2: after passing the practical test you drive unsupervised but under provisional conditions — P plates, zero blood alcohol, mobile-phone restrictions, and (for P1) passenger and other limits. P2 relaxes some conditions but the zero-alcohol rule and demerit sensitivity remain.
• Full licence: standard conditions apply, including the general blood-alcohol limit for full licence holders.

The exact minimum ages, required log hours, passenger rules and time you must hold each stage are set by DIT and do change — do not assume a figure a friend quotes. Confirm the current requirements at mylicence.sa.gov.au. The important teaching point is that road rules are not one-size-fits-all: a phone rule or alcohol limit that a full licence holder can live with will end a learner's or P-plater's licence far faster.

Key SA road rules every driver must know

These are the rules examiners test and police enforce most often. Learn the principle, not just the number.

• Speed limits: unless a sign says otherwise, the default limit in a built-up (urban) area is 50 km/h, and lower limits apply in school zones during signed times and near roadworks. Always drive to the signed limit; where no sign is present, the default applies. Confirm current default and school-zone limits with DIT.
• Passing emergency and roadside vehicles: SA requires drivers to slow right down when passing a stationary emergency, breakdown or roadside-assistance vehicle displaying flashing lights, and to move over safely if you can. This protects people working at the roadside — check the exact required speed with DIT, as it is a specific low limit.
• Mobile phones: heavily restricted. Learner and P1 drivers must not use a phone at all while driving. Full licence holders may only use a phone in limited hands-free ways. Touching or holding a phone to text or scroll is an offence carrying demerit points.
• Give way and roundabouts: at an uncontrolled intersection give way to the right; entering a roundabout, give way to any vehicle already on it and signal your exit. Indicate left as you leave.
• Keep left and overtaking: keep left unless overtaking, turning right, or the lane is otherwise required — especially on multi-lane roads signed 80 km/h or more.
• Seatbelts and children: every occupant must be properly restrained, with child restraints appropriate to age and size.

Signs are the language these rules are written in on the road — if you're rusty on what a particular sign means, work through our Australian road signs guide alongside the rules here.

Demerit points and fines in South Australia

SA runs a demerit points scheme. Each offence — speeding, running a red light, illegal phone use, not wearing a seatbelt — carries a set number of points, and the points sit against your licence for a period after the offence. Reach the threshold and your licence is suspended.

The single most important thing to understand: learner and provisional drivers have a much lower demerit threshold than full licence holders. A full licence holder can absorb several minor offences before suspension; a learner or P-plater can lose their licence from very few. This is deliberate — the system is strictest on the least experienced drivers.

Offences usually carry both demerit points and a fine, and some serious offences (high-range speeding, drink or drug driving) can mean immediate loss of licence and court. Points and dollar amounts are set by DIT and SAPOL and are reviewed regularly, so we deliberately do not print exact point totals, thresholds or fine amounts here — a stale number could cost you. Check the current demerit points, thresholds and penalties directly with DIT (mylicence.sa.gov.au) and SAPOL. The lesson to carry into the test and onto the road: drive as though every offence counts double while you're on L or P plates, because in effect it does.

Studying with the SA Driver's Handbook and the theory test

Your official study source is The Driver's Handbook, published by DIT and available free at mylicence.sa.gov.au. It's the document the theory test is drawn from, so read it — don't rely only on memory or interstate experience.

To get your learner's permit you must pass a theory test covering road rules, signs and safe-driving knowledge. South Australia does not publish the exact number of questions or the pass mark for the car theory test in a fixed public figure the way some states do, and the format is set by DIT — so confirm the current number of questions, pass mark and booking process with DIT before you sit it, rather than trusting a count you read online.

The most reliable way to prepare is repetition on realistic questions until the rules become automatic. Our free DKT practice lets you drill road rules and signs as many times as you like — every practice question is free, with no subscription and nothing to cancel. If you want structured hazard-perception coaching, that's the one paid extra: our Hazard Perception course is a one-time A$9.90 (a single payment, not a subscription) with a money-back guarantee — but you never need it to practise the road rules themselves.

Practise free, then test yourself

Reading the handbook tells you the rules; practising proves you've absorbed them. The fastest path to a confident SA learner's or provisional test is: read the relevant section of the Driver's Handbook, then immediately test yourself on those rules until you stop getting them wrong.

• Start with unlimited free SA-style practice questions — no sign-up, no payment.
• Brush up on the road signs you keep missing.
• Compare requirements in other states on our driving tests by state guide if you're moving interstate.
• Return to the road rules hub for the national rules that underpin SA's.

Confirm every official detail — ages, fees, demerit thresholds, test format — with DIT at mylicence.sa.gov.au before you book. The rules on this page teach the why; the authority holds the current numbers.
