Road Traffic Act 1974

The Act casts a wide net. Primary subjects are drivers and persons in charge of motor vehicles. Section 49AA deems an instructor providing driving instruction to a learner driver (defined in s. 49AAA by reference to learner's permits or authorisations under the Road Traffic (Authorisation to Drive) Act 2008) to be "in charge" for most Part V purposes (other than s. 49AB and s. 66A). This extends liability to supervisors seated beside or near the learner (s. 49AA(1)–(2)), though the learner remains personally liable (s. 49AA(3)).

Learner drivers, novice drivers and recently disqualified drivers face stricter rules. Section 64A(1) imposes a 0.02 BAC limit on novices (defined by reference to s. 40(2) of the authorisation Act), those subject to disqualification for drink/drug offences, extraordinary licence holders, and prescribed classes. Section 64AAA prohibits any detectable BAC for these persons. Commercial and heavy vehicle drivers (GCM ≥22.5 tonnes or carrying passengers for reward) are subject to zero-tolerance under ss. 62B(5), 64A(4)–(5) and 64C.

Instructors are separately regulated. Section 62B prohibits providing instruction with BAC ≥0.05 (or any BAC for certain high-risk instructors or heavy vehicles), while s. 62C bans prescribed illicit drugs in oral fluid or blood. Failure to comply with testing requirements attracts specific liability (s. 68A).

Vehicle owners, responsible persons and hirers are affected by impounding provisions. "Responsible person" is defined broadly in the Road Traffic (Administration) Act 2008 (via s. 5) and triggers notice requirements (s. 79B), liability for expenses (s. 79E, 80H, 80I) and potential confiscation (s. 80GA). Hirers and lenders receive protections (s. 80E), but owners must assist identification in harm incidents (s. 57).

Towing service providers, tow truck drivers, storage yard operators and controllers of premises are regulated by Part 6A. Towing parked vehicles requires a compliant towing arrangement (s. 94, 97), notification to the CEO, signage, waiting periods and direct routing to approved yards (ss. 97–101, 104). Unauthorised immobilisation or detention is prohibited (ss. 95, 105E), with abolition of common-law distress damage feasant (s. 105F). Charges are capped and liability imposed on relevant persons (ss. 105–105C).

Police officers receive extensive powers (ss. 66–66E, 71B, 78C, 79–79C, 80O) but are subject to defences when driving in emergency circumstances (ss. 61A–61B) and must follow procedural safeguards (s. 66(10), s. 70).

Event organisers and local governments must obtain road closure orders under Part VA (ss. 81B–81C), with offences for non-compliance (s. 81F).

All road users are affected by general duties (accident reporting, ss. 54–56), the radar detector ban (s. 81G) and the overarching regulatory power (s. 111).

The Act's reach extends via cross-references to external licensing authorities, prescribed classes, and corresponding laws in other jurisdictions (s. 49(9)). Transitional provisions (ss. 108–110A) preserve prior convictions and orders for recidivist calculations.

In practice, the Act affects practising lawyers advising on criminal defence, licensing appeals, impoundment challenges and civil recovery of towing/storage charges; compliance professionals in fleet management, towing businesses and event organisation; and accountants assessing expense recoverability under ss. 79E, 80K and 80W.

The Act imposes a dense web of duties while conferring corresponding rights and defences.

Duties of drivers and persons in charge:

• Authorisation: Drive only if authorised under the Road Traffic (Authorisation to Drive) Act 2008 Part 2 (s. 49(1)(a)). Instructors are deemed in charge (s. 49AA(2)).
• Accident response: Stop, assist and report (ss. 54–56). Failure where death or grievous bodily harm results is a crime (s. 56(2)).
• Manner of driving: Avoid dangerous (s. 61), reckless (s. 60) or careless (s. 62) driving. Specific prohibitions on excessive noise/smoke from tyres (s. 62A) and providing instruction while impaired (ss. 62B–62C).
• Alcohol and drugs: Maintain BAC below prescribed limits (ss. 63–64C) and avoid impairment (s. 64AB). Comply with all police testing requirements (ss. 66–67AD). Instructors face stricter zero-tolerance in some cases (s. 62B(2)–(5)).
• Impoundment-related: Surrender vehicles on notice (ss. 79BA–79BCE) and pay expenses if convicted (s. 79E).

Duties of owners/responsible persons:

• Assist identification (s. 57).
• Pay impounding, storage and sale-related expenses (ss. 79E, 80H, 80I, 80K, 80LA, 80W).
• Comply with surrender and non-disposal obligations during impoundment processes (s. 79BB(6), s. 79BCB(6), s. 79BCE(6)).

Police powers (and correlative duties):

• Require breath, blood, oral fluid or impairment assessments (ss. 66, 66A–66E).
• Impound vehicles (ss. 79, 79A, 80O) and issue disqualification notices (s. 71C).
• Prohibit driving for 24 hours where illicit drugs are detected (s. 71BA).
• Seize keys and move vehicles (s. 78C, s. 71B). Duties include facilitating medical assistance (s. 66(10)), providing statements of analysis (s. 68(9)), and revoking notices on acquittal (s. 71G).

Rights and defences:

• Defences to influence offences: Therapeutic use without knowledge of impairing effect (s. 63(7), s. 64AB(8)).
• Causation defences for dangerous/careless driving (s. 59B(6)–(7), s. 59BA(2)).
• Necessity permits for penalty-disqualified drivers who were unaware (s. 49A).
• Release of impounded vehicles on hardship, stolen/hired status, or service/test-drive circumstances (s. 79D(2)).
• Court review of disqualification notices (s. 71F) and impounding orders (s. 80G).
• Evidentiary rights: Challenge certificates with notice (s. 70B(4)–(5), s. 70(5)–(5b)).
• Protection against DNA use (s. 71A) and use of preliminary test results (s. 70(5c)–(5e)).

Sentencing rights: Pre-sentence reports for drug impairment (s. 106(6)); community orders in lieu of fines for first offences (s. 106(3), (7)); credit for notice disqualification periods (s. 71H).

These duties and rights are not static; aggravating circumstances under s. 49AB (never held licence, escape from pursuit, 30 km/h+ over limit) trigger mandatory minimums and non-suspendable sentences (ss. 59(4A)–(4B), 60B(5)).

Penalties are structured for deterrence, with mandatory disqualification (s. 106A) and recidivist loading.

Fines and imprisonment:

• Unlicensed driving: 6–80 PU plus imprisonment up to 18 months depending on circumstances (s. 49(1)).
• Dangerous driving causing death: Up to 20 years (s. 59(3)); causing bodily harm: up to 10 years (s. 59A(3a)).
• Reckless driving: 120–240 PU or 9–12 months, permanent disqualification on third offence (s. 60B).
• Drink/drug driving: Tables in ss. 64, 64AA, 64B, 64C prescribe minimum fines (15–72 PU) and disqualification (3 months to permanent) scaled by BAC and priors. Combined offences carry higher minima.
• Failure to provide samples: Up to 225 PU or 18 months, permanent disqualification (s. 67(2)).
• Impounding offences: Court-ordered confiscation (ss. 80A, 80C, 80CB) or impoundment up to 6 months (s. 80FA).

Disqualification:

• Mandatory minimums (e.g. 2 years for dangerous driving causing death, s. 59(3)).
• Police-issued notices under s. 71C (up to 2 months, taken into account on sentencing per s. 71H).
• Permanent disqualification for repeat reckless or high-BAC offences (ss. 60B(3)(c), 63(1)(e)).

Vehicle sanctions:

• Impoundment (28 days to 3 months) or confiscation (ss. 79–80CB). Sale proceeds applied to expenses then Road Trauma Trust Account or Confiscation Proceeds Account (s. 80J(7)).
• Towing/storage charges capped by regulation; liability on relevant persons (s. 105C).

Enforcement:

• Arrest without warrant for many offences (ss. 49(3), 63(3A), 64(1), 67(3A), 71B).
• Evidentiary aids: Certificates prima facie evidence (s. 70(2)–(3b)); presumptions of BAC or drug presence (s. 71).
• Impoundment by police (Subdivision 2) or court (Subdivision 3), with senior officer oversight (s. 79C).
• Regulations under s. 111 authorise further enforcement mechanisms, including fees and exemptions (s. 111AB).

Sentencing under s. 106 requires consideration of priors (s. 106(4)), with mandatory program/supervision orders for drug offences (s. 106(7)–(8)).

The Act is not standalone. Section 5 incorporates definitions from the Road Traffic (Administration) Act 2008 Part 1 Division 2. Driver authorisation, licensing and extraordinary licences are primarily governed by the Road Traffic (Authorisation to Drive) Act 2008, with the present Act cross-referencing disqualification, suspension and prescribed classes (ss. 49, 62B, 64A).

Penalty enforcement links to the Fines, Penalties and Infringement Notices Enforcement Act 1994 (s. 49(9), s. 71C). Sentencing interacts with the Sentencing Act 1995 (non-suspendable terms under ss. 59(4B), 60B(5); community orders per s. 106). The Criminal Code supplies the definition of grievous bodily harm (via s. 49AAA) and interacts with dangerous driving (s. 59(2A) preserves pre-2011 manslaughter rules).

Evidentiary and procedural rules engage the Evidence Act 1906 and Criminal Procedure Act 2004. Impounding expense recovery is a civil debt (s. 78E). Towing and storage are further regulated by the Towing Services Act 2024 (once commenced) and interact with consumer protection legislation via capped charges (s. 105B).

Road closure orders under Part VA interface with the Public Order in Streets Act 1984 (s. 81E(1)(a)). Radar detector offences (s. 81G) complement average speed and speed camera provisions in the Road Traffic (Administration) Act 2008 ss. 117–117B.

Transitional provisions (ss. 108–110A) preserve convictions under repealed Traffic Act 1919 and earlier versions for recidivism calculations (s. 49(6)–(7)). Regulations under s. 111 can exempt from other road laws.

In practice, practitioners must navigate the Road Traffic (Vehicles) Act 2012 for registration, the Dangerous Goods Safety Act 2004 for heavy vehicle rules (s. 64A(5)(e)), and federal Personal Property Securities Act 2009 for security interests in confiscated vehicles (s. 80D).

The Act has been substantially amended to address emerging safety risks, evidentiary difficulties and enforcement gaps.

The Road Traffic Amendment (Impaired Driving and Penalties) Act 2020 (assented 9 July 2020, various commencements 2020–2021) introduced combined alcohol and prescribed illicit drug offences (new ss. 64B–64D). Section 64B creates offences where BAC ≥0.05 (or ≥0.08) coincides with a prescribed illicit drug in oral fluid or blood, with Table-based penalties mirroring but exceeding standalone drink-driving minima. Section 64C extends zero-tolerance to certain drivers/vehicles. These changes responded to research showing compounded impairment from polysubstance use, with s. 64D providing presumptions of presence within 4 or 12 hours. Consequential amendments updated failure-to-comply offences (ss. 67AC–67AE) and evidentiary rules (s. 70(3a)).

The Road Traffic Amendment (Impounding and Confiscation of Vehicles) Act 2016 (commenced 14 January 2017) expanded Division 4. New ss. 79BA–79BCE introduced surrender notices and substitute/alternative vehicle mechanisms to overcome practical impoundment difficulties. Court-ordered confiscation was broadened (s. 80A now covers school zones and 90 km/h+ excesses). Proceeds distribution was refined (s. 80J(7)). These changes targeted repeat "hoon" offenders, reflecting community concern over anti-social driving.

Earlier, the Road Traffic Amendment (Blood Alcohol Content) Act 2019 adjusted BAC presumptions (s. 71) to align with 12-hour sampling windows for serious incidents (s. 66(8B)).

The Road Traffic Amendment (Immobilisation, Towing and Detention of Vehicles) Act 2020 (commenced 14 December 2020) inserted Part 6A. It prohibits unauthorised wheel-clamping (s. 95) and detention (s. 105E), regulates towing via mandatory arrangements, CEO notification, signage, waiting periods and approved yards (ss. 94, 97–104), and caps charges (ss. 105–105B). These reforms addressed consumer complaints about predatory towing practices, abolishing common-law distress damage feasant (s. 105F) and voiding prohibited-service contracts (s. 105H).

The Road Traffic Legislation Amendment Act 2012 (various commencements 2012–2015) transferred licensing provisions, inserted drug testing regimes (ss. 66C–66E, 69B, 70A–70B) and updated evidentiary certificates.

These amendments respond to data on drug driving, repeat offenders, and towing abuses, while improving evidentiary efficiency and aligning with national harmonisation.

The source text does not detail specific court challenges; however, the Act's structure anticipates evidentiary disputes. Section 70 provides extensive certificate-based prima facie evidence for analysis results, breath equipment operation and drug impairment assessments. Subsections 70(5)–(5b) require 28 days' notice to challenge certificates, with 14 days' notice of specific matters, reflecting legislative intent to streamline prosecutions while preserving natural justice. Section 70B similarly governs delivery certificates.

Controversies implicit in the text include the breadth of "in charge" deeming for instructors (s. 49AA(2)), which extends liability without physical control, and the strict liability elements in many testing offences (ss. 67–67AD), where "substantial reason" other than avoidance of evidence is the only defence (s. 67(5), s. 67AA(5), s. 67AB(5), s. 67AE(3)).

Mandatory minimum disqualification and non-suspendable sentences (ss. 59(4A)–(4B), 60B(5), 106A) limit judicial discretion, a point of ongoing debate in sentencing circles. The 24-hour prohibition notices for illicit drugs (s. 71BA) and police disqualification notices (s. 71C–71H) introduce administrative licence suspension before conviction, balanced by court revocation rights (s. 71F) and credit on sentencing (s. 71H).

Impounding on surrender notices where the driver is later acquitted (s. 79BC) limits expense recovery to the shorter period, with refunds (s. 79BC(6)). Confiscation of hired or lent vehicles is prohibited (s. 80E), protecting innocent third parties.

The text contains no explicit controversy recitals, but the layered defences (therapeutic use, s. 63(7); non-attribution, s. 59B(6)) and presumptions (BAC ≥0.15 equals incapacity, s. 59B(5); presence within 4/12 hours, s. 64D(1)) indicate legislative balancing of enforcement efficiency against individual rights.

Most practitioners appreciate the graduated BAC tables but miss the interaction between s. 64A(2)(f) ("recently disqualified driver" within 3 years) and the zero-tolerance rule in s. 64AAA(1). A driver who completed a disqualification period for a s. 64 offence three years and one day ago may still face the lower 0.02 limit if they fall within another s. 64A(2) category.

Instructors are frequently overlooked. Section 49AA(2) deems them "in charge" for alcohol and drug offences (other than s. 49AB and s. 66A), exposing them to the full suite of s. 63–64C liabilities even if the learner is the actual driver. Section 62B(4)–(5) imposes zero BAC for instructors who have been disqualified in the last 3 years or hold extraordinary licences, with s. 68A creating a specific 50 PU offence for non-compliance with testing.

The "circumstances of aggravation" in s. 49AB(1) are broader than many realise. Never having held a prescribed authorisation (s. 49AB(1)(aa)), driving an unauthorised class of vehicle (s. 49AB(1)(ac)), or committing an offence under the authorisation Act s. 38(1) (s. 49AB(1)(ad)) all trigger higher penalties and mandatory imprisonment on pursuit (ss. 59(4A), 60B(4)–(5)).

Surrender notices (s. 79BA) and substitute vehicle notices (s. 79BCA) create strict liability for non-compliance (50 PU under ss. 79BB(5)–(6), 79BCB(5)–(6)), including a prohibition on actions reducing vehicle value. Many owners inadvertently breach by selling or repairing during the notice period.

Evidentiary "gotchas" abound. The 12-hour sampling window for serious incidents (s. 66(8B)) triggers longer presumptions (ss. 64D(1), 71(1)(a)). Certificates under s. 70 are prima facie but require 28-day notice to challenge (s. 70(5)), with specific 14-day notice of matters (s. 70(5a)–(5b)). Failure to give notice can preclude cross-examination on chain of custody.

Police disqualification notices (s. 71C) run concurrently with other disqualifications (s. 71D(2)) but must be taken into account on sentencing (s. 71H). An acquittal automatically revokes them (s. 71G), yet many practitioners forget to seek revocation orders under s. 71F where exceptional circumstances exist.

Storage and towing charges under Part 6A are capped, but the regulations (not reproduced here) prescribe different maxima depending on vehicle type, distance and work performed. Agreements purporting to authorise prohibited towing are void (s. 105H), exposing operators to non-recovery of fees already paid.

Finally, the "previous offender" definition for 3-month impoundment (s. 79(1A)) includes pending charges; an acquittal reduces the period retrospectively with refunds (s. 79BC).

Compliance requires a systematic approach grounded in the statutory text.

For drivers and supervisors:

• Verify current authorisation under the Road Traffic (Authorisation to Drive) Act 2008 before driving (s. 49(1)). Carry foreign licences and translations (s. 50A).
• In any incident, stop immediately, render assistance, exchange details and report (ss. 54–56). Document injuries preventing compliance (s. 54(7), s. 55(5), s. 56(5)).
• Maintain BAC below applicable limit (zero for learners, novices, commercial drivers; 0.05 or 0.02 otherwise). Avoid all prescribed illicit drugs (ss. 64AC–64C). If providing instruction, comply with stricter instructor rules (s. 62B–62C).
• On police request, provide samples or undergo assessment (ss. 66–66A). Refusal triggers separate serious offences (ss. 67–67AD).

For owners and fleet managers:

• Ensure all drivers hold appropriate authorisation and are not subject to notices (s. 49(3)).
• On receiving a surrender notice (s. 79BA) or impoundment notice (s. 79B), comply strictly; do not dispose of or devalue the vehicle (s. 79BB(6)). Apply for release under s. 79D grounds (stolen, hired, hardship, service/test drive, business use) with statutory declarations where required.
• Budget for potential expenses (ss. 79E, 80H, 80I). Where a vehicle is sold under s. 80J, monitor distribution of proceeds.

For towing and storage operators:

• Enter only compliant towing arrangements meeting the approved form and call-out charge requirement (s. 94(2)). Provide copies on request (s. 102).
• Before towing a parked vehicle, confirm signage, waiting period, CEO notification, records and inability to locate a relevant person (or their unwillingness to move the vehicle) (s. 97). Use the most direct route to an approved yard (s. 101, s. 104).
• Release on demand after storage (s. 103) or on payment of capped on-site release charge (s. 100). Do not impose uncapped or prohibited charges (ss. 105–105B).
• Maintain approved storage yards and ensure all drivers and yard staff have access to arrangements (s. 104, s. 102(4)).

For legal practitioners:

• When advising on drink/drug charges, obtain full testing chain documentation. Challenge certificates only after 28-day notice and with particularised 14-day notice (s. 70B(4)–(5)). Argue therapeutic use defences with evidence of prescription and lack of knowledge (s. 63(7), s. 64AB(8)).
• For impoundment, identify s. 79D(2) grounds early. Where a previous-offender 3-month period was imposed on a pending charge later withdrawn, invoke s. 79BC for reduction and refund.
• In sentencing, seek credit for s. 71C notices (s. 71H) and argue exceptional hardship for release or against confiscation (s. 79D(2)(c), s. 80G(5)–(6A)). For drug impairment, obtain pre-sentence reports (s. 106(6)) and advocate for program orders (s. 106(7)–(8)).
• Advise corporate clients on Part 6A compliance programs, including scripted interactions with relevant persons and record retention to defend against s. 97(4) or charge-capping offences.
• Monitor regulations under s. 111 for updated maxima, signage requirements and exemption classes (s. 111AB).

General compliance tips:

• Maintain detailed incident logs, including times, to engage 4-hour/12-hour presumptions (s. 64D(1), s. 71).
• For events, apply for closure orders well in advance (s. 81B) and ensure barriers conform to prescribed standards (s. 81D).
• Review transitional provisions where prior convictions are involved (ss. 49(6)–(7), 109–110A).
• Use the CEO notification portal under s. 97(1)(b) and approved forms for all notices to avoid technical invalidity.

Compliance is not merely reactive; regular auditing of driver qualifications, vehicle status and towing contracts, coupled with targeted training on s. 49AA instructor liability and s. 71BA 24-hour prohibitions, minimises exposure. Where doubt exists, obtain senior police officer confirmation under s. 79C before impoundment actions. Legal sign-off on all surrender notices and storage releases is prudent given the 50 PU strict liability offences.
