Australia Driving Laws by State: Demerit Points, BAC Limits and E-Scooter Rules (2026)

Driving law in Australia runs on eight separate state and territory systems, not one national code. Demerit thresholds, blood alcohol limits, mobile phone fines and e-scooter legality all diverge by jurisdiction, and getting New South Wales's e-scooter ban or the Northern Territory's low-power cap wrong can put a reader in front of a fine.

Jurisdiction scope: This hub compares core road-traffic rules, demerit points, blood alcohol limits, mobile phone law and e-scooter law, across all eight Australian states and territories: New South Wales, Victoria, Queensland, Western Australia, South Australia, Tasmania, the Australian Capital Territory and the Northern Territory. It is general legal information, verified 20 July 2026, not legal advice about a specific infringement, licence or court matter. Each jurisdiction runs its own road traffic legislation, and nothing on this hub overrides the specific rules that apply where the driving took place.

Driving Law Is Eight Systems, Not One

Road transport is a state and territory responsibility in Australia, so there is no single national road traffic act. Each of the eight jurisdictions runs its own legislation, its own demerit point scheme, its own penalty schedule indexed against its own penalty unit, and its own approach to newer vehicle categories such as e-scooters. A rule that is true in Sydney can be flatly wrong in Perth or Darwin. Two examples show how far this goes: New South Wales still bans privately owned e-scooters from every public place in the state, while the Northern Territory allows them but caps them at 200 watts and 10 km/h, a limit most commercially sold e-scooters exceed by a wide margin. Treat "Australian driving law" as shorthand for eight parallel regimes rather than one, and always confirm the applicable rule in the specific state or territory where the driving happened, not the state where a reader may have driven before.

The 8-Jurisdiction Comparison Matrix

Figures are tagged to the 2026-27 Australian financial year where a fine amount is shown. Every jurisdiction re-indexes at least some penalties on 1 July, so a figure carried into a later financial year should be re-checked against the source.

Demerit Points: Not "12 Points, Except NSW"

The common shorthand that every Australian jurisdiction runs a 12-point demerit scheme except New South Wales, which uses 13, understates how different the systems really are. Novice thresholds diverge far more sharply than full-licence thresholds: NSW splits its provisional category into P1 (4 points) and P2 (7 points), Western Australia splits novice drivers into a Type 1 group under two years' experience (4 points) and a Type 2 group with one to two years remaining (8 points), and the Northern Territory sets a single novice threshold of 5, not 4. Victoria uses a dual test rather than a single number: a probationary driver is suspended on 5 points within 12 months or 12 points within 3 years, whichever comes first. The accrual window itself, not just the threshold, differs by licence class in Queensland, Tasmania and the Northern Territory, where an open licence gets a 3-year window but a novice licence is measured over 12 months. Full detail, including every jurisdiction's suspension mechanics, is in demerit points explained across Australia.

Drink Driving: One BAC Limit, Different Penalty Structures

Every Australian jurisdiction sets its general blood alcohol concentration limit at 0.05, and every jurisdiction applies a zero or reduced limit to learner and provisional drivers. Beyond that shared starting point, the statutory structures diverge. Western Australia and the ACT do not use a three-tier low, medium, high model at all: WA sets five numbered BAC bands from 0.05-0.079 up to 0.13 and above, each carrying its own minimum disqualification and fine, and the ACT's Road Transport (Alcohol and Drugs) Act 1977 defines four numbered offence levels under section 4E. South Australia structures its penalties by BAC category multiplied by whether the reading is a first or subsequent offence within five years, and the Northern Territory uses four bands running from zero tolerance for learner and provisional drivers up to a high-range band at 0.15 and above. Victoria's statutory disqualification and impoundment framework is well documented, but its tiered dollar fine amounts could not be verified from a live primary source at the time of writing and are not published here. Full detail is in drink driving limits across Australia.

E-Scooters: The Biggest Trap in the Cluster

E-scooter legality is the least uniform rule in this entire hub, and the two extremes sit at opposite ends of the spectrum. In New South Wales, riding a privately owned e-scooter in any public place remains illegal; the only lawful e-scooter riding is on a shared operator's device inside a designated trial site, and a 2026 legalisation proposal has been announced but has not commenced. In the Northern Territory, private e-scooters are legal, but the device itself must not exceed 200 watts of power or 10 km/h, a specification far below the 25 km/h most retail e-scooters are built and sold to reach; a device that exceeds either figure is treated as an unregistered, uninsured motor vehicle. Every other jurisdiction, Victoria, Queensland, Western Australia, South Australia, Tasmania and the ACT, permits private e-scooters under a 25 km/h device cap, but each sets its own age, helmet and path rules, and Queensland is mid-reform with one rule already in force and a second not yet commenced. Full detail, including every jurisdiction's speed and path rules, is in e-scooter laws in Australia.

Mobile Phones and Detection Cameras

Every jurisdiction bans hand-held mobile phone use while driving, and every jurisdiction now enforces that ban partly through camera-based detection technology, except one. The Northern Territory is the only Australian jurisdiction that operates no mobile phone detection cameras at all; enforcement there relies on police observation. NSW pioneered the technology nationally, Victoria's cameras have operated since April 2023, Queensland's since around 2021, South Australia's since June 2024, Tasmania uses Sensys Gatso units since 2022, the ACT operates both fixed and portable units, and Western Australia moved from a caution-only phase from 26 January 2025 into full enforcement from 8 October 2025. Fine amounts and demerit points for a hand-held mobile phone offence vary by jurisdiction and, in Queensland, Western Australia and the NT, by exactly what the driver was doing with the device. Full detail is in mobile phone detection cameras in Australia.

Speeding Fines and Window Tint

Speeding penalties scale with how far over the limit a driver was travelling, and every jurisdiction's dollar bands and demerit points are its own; Queensland's top band reaches $1,986 and 8 points for driving more than 40 km/h over the limit, while Western Australia's equivalent top band is $1,200 and 7 points for more than 40 km/h over. Full state-by-state bands are in speeding fines in Australia. Window tint law is set by a minimum visible light transmission percentage for the front side windows, rear windows and windscreen of a vehicle, and while most jurisdictions converge on 35% front and 20% rear, the Northern Territory permits a genuinely different 15% rear minimum, traced to a 2009 regulatory exemption rather than an error in reporting. Full detail, including the correct current Western Australian regulation, is in window tint laws in Australia.

Demerit Points by State and Territory

Each jurisdiction's demerit scheme has its own thresholds, accrual windows and suspension mechanics, covered in full on its own page.

• New South Wales demerit points, the only jurisdiction with a 13-point full-licence threshold and a split P1/P2 novice system.
• Victoria demerit points, the only jurisdiction using a dual 5-in-12-months or 12-in-3-years novice test.
• Queensland demerit points, where the accrual window itself shortens to 1 year for a provisional licence.
• Western Australia demerit points, with a two-tier novice threshold of 4 or 8 points depending on experience.
• South Australia demerit points, where a provisional driver at 4 points can choose a Safer Driver Agreement instead of disqualification.
• Tasmania demerit points, with a 12-month novice accrual window against a 3-year full-licence window.
• Australian Capital Territory demerit points, with a legacy 12-point threshold for learner licences issued before 1 January 2020.
• Northern Territory demerit points, the only jurisdiction with a 5-point, rather than 4-point, novice threshold.

This hub provides general legal information about driving and road traffic law across Australia, verified 20 July 2026. It is not legal advice, and how the law applies depends on the state or territory where the driving took place and on the specific facts of the matter. For advice about a specific fine, licence suspension or charge, consult a legal practitioner admitted in the relevant Australian state or territory, or the transport authority or police service in that jurisdiction.
