Civil Law and Comparative Autonomous Transport Regulation Models

1. Introduction

Autonomous transport regulation concerns the laws, regulatory institutions and civil-liability principles governing vehicles and transport systems that perform some or all driving, navigation or operational functions without continuous human control.

These technologies include autonomous passenger cars, driverless taxis, automated buses, autonomous trucks, delivery robots, connected vehicles and automated maritime transport. They also involve supporting technologies such as artificial intelligence (AI), sensors, satellite navigation, vehicle-to-infrastructure communications and automated traffic-management systems.

From a civil-law perspective, the central issue is how to allocate legal responsibility when an autonomous transport system causes an accident, damages property, breaches a transport contract or makes an unsafe operational decision.

For example, if a driverless vehicle collides with a pedestrian because its perception system fails, responsibility may potentially involve the vehicle manufacturer, software developer, fleet operator, maintenance provider or another party. The outcome depends on the applicable law, the facts, the causal connection and the duties owed by each party.

The principal objectives of autonomous transport regulation are:

Protecting passengers, pedestrians and other road users.

Establishing safety standards for autonomous systems.

Determining liability for accidents and technical failures.

Regulating testing, approval, deployment and operation.

Protecting consumers and personal data.

Ensuring that insurance and compensation mechanisms remain effective.

Facilitating technological innovation without compromising public safety.

This analysis compares Australia, the European Union, the United States and selected civil-law jurisdictions, including Germany and France.

2. Meaning and scope of autonomous transport regulation

Autonomous transport regulation combines public law, private law, administrative regulation, product-safety rules and insurance law.

A. Autonomous road vehicles

Driverless cars, robotaxis, automated shuttles and autonomous trucks raise questions about vehicle approval, operational safety, accident liability and insurance.

B. Public and commercial transport

Automated buses, freight vehicles and mobility services require rules governing operators, passenger safety, service contracts and emergency intervention.

C. Autonomous maritime transport

Automated vessels raise issues of navigational responsibility, seaworthiness, collision liability, maritime insurance and international shipping standards.

D. Connected transport infrastructure

Smart traffic signals, automated traffic management and vehicle-to-infrastructure systems create potential liability for infrastructure operators and technology providers.

Levels of driving automation

Automation is commonly described using six levels, from Level 0 to Level 5.

These levels are descriptive engineering classifications, not universal permissions to operate on public roads. Actual legal authorisation depends on the jurisdiction, vehicle type, operational conditions and applicable approval requirements.

3. Australian autonomous transport regulation

Australia combines federal vehicle-safety regulation, state and territory road laws, compulsory motor accident insurance arrangements and common-law principles governing negligence and compensation.

The National Transport Commission (NTC) has developed a national regulatory framework intended to address the deployment of automated vehicles, including national safety oversight and responsibility for automated driving systems. Its framework identifies the need for coordinated rules concerning safety, insurance and access to vehicle data.

The central legislative and institutional components include:

Road Vehicle Standards Act 2018 (Cth): regulates the entry of road vehicles into the Australian market and relevant vehicle approval requirements.

Australian Consumer Law: provides protections relating to consumer guarantees, misleading conduct and defective goods, where the applicable provisions are satisfied.

State and territory road-traffic legislation: regulates vehicle use, driver obligations and road safety.

State and territory compulsory motor accident insurance schemes: provide statutory compensation according to the relevant scheme.

Common-law negligence: may govern claims against manufacturers, operators, maintenance providers and other parties.

Australia's challenge is to ensure that laws designed around human drivers can accommodate vehicles that may operate without a human driver continuously controlling the vehicle.

A manufacturer may be responsible for a defect, while a fleet operator may be responsible for inadequate maintenance or unsafe deployment. A software provider may also face liability if its conduct satisfies an applicable cause of action. The allocation of responsibility depends on evidence and the governing legal rules, rather than on the mere presence of autonomous technology.

4. European Union model

The European Union combines harmonised vehicle-approval requirements, product-safety law and national civil-liability systems.

Important instruments include Regulation (EU) 2018/858 on motor-vehicle approval, Regulation (EU) 2019/2144 on general vehicle safety, and Regulation (EU) 2024/1689, the AI Act, where its provisions apply to the relevant systems and actors.

The revised Product Liability Directive (EU) 2024/2853 expressly modernises the EU's product-liability framework to account for digital products, software and related technological developments. Member states must transpose the directive within the timetable prescribed by the legislation, with its new rules applying to products placed on the market or put into service after the relevant application date.

The EU approach addresses several questions:

Does the vehicle satisfy applicable technical and safety requirements?

Is a software or hardware defect responsible for the harm?

Which entity qualifies as a manufacturer, importer or other responsible economic operator?

What compensation is available under EU and national law?

How should evidence be obtained where technical information is controlled by the manufacturer?

The EU's principal advantage is the harmonisation of important product-safety and product-liability rules across member states. However, national tort law, insurance law and procedural rules continue to influence many disputes.

5. United States model

The United States combines federal vehicle-safety oversight with state-based rules on road use, insurance and civil liability.

The National Highway Traffic Safety Administration (NHTSA) administers federal motor-vehicle safety requirements and investigates safety defects. State laws generally determine important aspects of negligence, product liability, insurance and vehicle operation.

Autonomous transport disputes may involve:

Defective vehicle design or software.

Negligent testing and deployment.

Failure to warn consumers about system limitations.

Negligent maintenance or fleet supervision.

Misrepresentation concerning the vehicle's capabilities.

Unreasonable reliance on driver-assistance technology.

The US system does not treat every accident involving an automated vehicle as proof of a product defect. Courts examine the evidence, the applicable legal standard and the causal relationship between the alleged defect or misconduct and the injury.

Compared with the EU's harmonised product-liability legislation, the United States retains significant variation between state liability rules. That variation can affect available causes of action, damages and litigation procedures.

6. Germany and France: civil-law approaches

Germany

Germany provides one of the clearest examples of legislation specifically addressing autonomous road vehicles.

The German Road Traffic Act (Straßenverkehrsgesetz, StVG), including sections 1a and 1e, provides a framework for highly automated and autonomous driving functions. Section 1e addresses the operation of vehicles with autonomous driving functions within authorised operating areas and under specified technical and regulatory conditions.

Germany also retains an established framework of vehicle-holder liability and compulsory motor insurance. The statutory system can provide an injured person with a route to compensation without requiring every claim to begin with proof of negligence by a particular software developer.

The German model illustrates an important principle: the person or entity legally responsible for operating a vehicle may bear liability even where the immediate cause of an accident is an automated system, subject to the applicable statutory conditions and defences.

France

France combines the Civil Code, the Highway Code (Code de la route), product-liability legislation and rules specifically addressing automated road transport.

The French Civil Code contains general principles governing contractual and non-contractual liability. Article 1240, for example, provides the general basis for liability for fault causing damage, while other provisions address liability for things and defective products.

France also has a special statutory framework for the use of automated road vehicles and the allocation of certain criminal and operational responsibilities when an automated driving system is engaged. The details depend on the vehicle, its authorisation and the conditions of operation.

The French approach illustrates how general civil-law principles can be supplemented by specialised legislation for technologies that change who controls a vehicle.

7. Case laws relevant to autonomous transport regulation

The following cases provide judicial principles relevant to autonomous transport, including product defects, negligence, causation, vehicle safety and compensation. Because autonomous-vehicle litigation remains a developing field, some of these are foundational cases rather than decisions directly involving fully driverless vehicles.

Case 1: Donoghue v Stevenson [1932] AC 562

Court: House of Lords, United Kingdom.

Facts: Mrs Donoghue consumed ginger beer purchased by a friend. The bottle allegedly contained the remains of a decomposed snail, and she became ill. She had no direct contract with the manufacturer.

Legal issue: Could a manufacturer owe a duty of care to a consumer who had no direct contractual relationship with it?

Decision: The House of Lords recognised that a manufacturer may owe a duty of care to the ultimate consumer where the product reaches that consumer in a condition that creates a foreseeable risk of injury.

Legal principle: Manufacturers must take reasonable care to avoid foreseeable injury to persons who may be affected by their products.

Application to autonomous transport: If a vehicle manufacturer releases an autonomous driving system with an unsafe perception capability, inadequate collision avoidance or a dangerous software defect, the principles underlying manufacturer negligence may be relevant.

The claimant must still establish the applicable duty, breach, causation and loss. The case does not establish automatic liability for every autonomous-vehicle accident.

Comparative significance: The decision is foundational to common-law product negligence and remains relevant when comparing common-law manufacturer liability with civil-law product-liability regimes.

Case 2: Grant v Australian Knitting Mills Ltd [1936] AC 85

Court: Privy Council, on appeal from Australia.

Facts: Dr Grant purchased woollen underwear that allegedly contained excessive chemical residue from manufacturing. Wearing the garment caused dermatitis.

Legal issue: Could a manufacturer be liable where a product reached the consumer without an intervening inspection that would reveal the defect?

Decision: The Privy Council upheld liability against the manufacturer and retailer under the applicable principles.

Legal principle: A manufacturer may owe a duty to the ultimate consumer where a product is intended to reach that consumer without an intervening examination capable of revealing the relevant defect.

Application to autonomous transport: The case offers a useful analogy for hidden software and hardware defects. A consumer purchasing a vehicle may be unable to inspect its source code, sensor-fusion architecture or internal safety controls.

Where the applicable law recognises manufacturer liability, the inability of a consumer to detect an internal defect can be important to the analysis.

Comparative significance: The case demonstrates the development of Australian product-liability principles and their relationship with broader common-law doctrine.

Case 3: Wyong Shire Council v Shirt (1980) 146 CLR 40

Court: High Court of Australia.

Facts: A man was injured while water-skiing in an area where the water's depth created a risk of injury. The dispute concerned the adequacy of precautions and the standard of reasonable care.

Legal issue: How should a court determine whether a reasonable person would have taken precautions against a foreseeable risk?

Decision: The High Court explained the negligence analysis by reference to the probability of harm, its likely seriousness, the burden of taking precautions and the social utility of the activity.

Legal principle: A foreseeable risk does not automatically establish negligence. The court must assess whether reasonable precautions were required in the circumstances.

Application to autonomous transport: A manufacturer or fleet operator may know that sensors can fail in heavy rain, that road markings may be difficult to detect or that a system has limitations in certain operating conditions.

The negligence question includes whether the risk required additional testing, a warning, a software restriction or suspension of the vehicle's operation.

Comparative significance: The case illustrates Australia's risk-based negligence approach. Comparable civil-law jurisdictions also assess fault and reasonable precautions, although the doctrinal structure may differ.

Case 4: March v E & MH Stramare Pty Ltd (1991) 171 CLR 506

Court: High Court of Australia.

Facts: A truck was parked across part of a roadway, and a driver collided with it. The circumstances raised questions about the causal significance of the truck operator's conduct and the other driver's actions.

Legal issue: How should courts determine causation where multiple factors contribute to an accident?

Decision: The High Court discussed the role of common-sense causation alongside legal principles governing responsibility for damage.

Legal principle: Causation is not always resolved by a purely mechanical test. Courts must evaluate the facts and determine whether the defendant's conduct should legally be regarded as a cause of the damage.

Application to autonomous transport: An autonomous-vehicle collision might involve several contributing factors:

A software defect.

A sensor obscured by weather.

Inadequate vehicle maintenance.

Unsafe road design.

Another road user's conduct.

The court must determine which factors legally caused the injury and whether responsibility should be apportioned under the applicable law.

Comparative significance: The case is important for analysing multiple-party liability and causation in technologically complex accidents.

Case 5: Perre v Apand Pty Ltd [1999] HCA 36

Court: High Court of Australia.

Facts: The case concerned economic loss suffered by potato growers after the introduction of a bacterial disease affected their ability to sell produce. The plaintiffs' losses arose from restrictions associated with the disease rather than direct physical damage to their own property.

Legal issue: In what circumstances can a person recover pure economic loss caused by another party's negligence?

Decision: The High Court recognised that a duty of care for pure economic loss may arise in particular circumstances, depending on the relevant features of the relationship and the foreseeability and vulnerability of the affected parties.

Legal principle: Foreseeability alone is not always sufficient to establish a duty to prevent pure economic loss. The court must consider the relevant legal factors governing the scope of the duty.

Application to autonomous transport: A transport-system failure may cause financial losses beyond physical injury, such as delivery delays, business interruption or loss suffered by dependent service providers.

Whether such losses are recoverable depends on the applicable cause of action, the nature of the loss and the relationship between the parties.

Comparative significance: The decision is useful for distinguishing claims for physical injury or property damage from claims for consequential or pure economic loss.

Case 6: Vnuk v Zavarovalnica Triglav d.d. (Case C-162/13, 2014)

Court: Court of Justice of the European Union.

Facts: Mr Vnuk was injured when a tractor with a trailer reversed in a farmyard and struck a ladder on which he was standing. The dispute concerned the scope of compulsory motor-vehicle insurance under EU law.

Legal issue: Did compulsory motor insurance extend to an accident involving the use of a vehicle in private premises?

Decision: The Court interpreted the relevant EU insurance legislation broadly, focusing on whether the vehicle's use was consistent with its normal function as a means of transport.

Legal principle: The scope of compulsory motor insurance under the relevant EU rules is not necessarily confined to accidents occurring on public roads.

Application to autonomous transport: Autonomous vehicles may operate in car parks, private industrial sites, depots, residential complexes and other non-public areas. The case illustrates why insurance coverage depends on the applicable legal definition of vehicle use rather than a simple assumption that only public-road accidents are covered.

Comparative significance: The decision demonstrates how EU law can harmonise aspects of motor insurance while leaving other issues to national legal systems.

Case 7: Axa General Insurance Ltd v Lord Advocate [2011] UKSC 46

Court: Supreme Court of the United Kingdom.

Facts: The case involved a challenge to Scottish legislation establishing a compensation scheme for certain victims of asbestos-related disease. The litigation concerned the validity of the legislation and the legal framework for compensation.

Legal issue: What limits govern judicial review of legislation and the legal arrangements created to compensate people suffering injury?

Decision: The Supreme Court rejected the challenge to the legislation.

Legal principle: The case addresses the relationship between legislative authority, public-law review and legal arrangements intended to respond to injury.

Application to autonomous transport: Governments may develop statutory insurance or compensation schemes to address injuries caused by emerging technologies. The case provides broader context for understanding how compensation policy interacts with legislative authority and judicial oversight.

Comparative significance: Although not a transport case, it illustrates the importance of public-law institutions when legislatures establish new compensation frameworks.

Case 8: Volkswagen (Right to Adequate Compensation) (Case C-666/23, 1 August 2025)

Court: Court of Justice of the European Union.

Facts: The proceedings concerned vehicles equipped with an unlawful emissions defeat device and the rights of individual purchasers to compensation under the relevant EU vehicle-approval and emissions legislation.

Legal issue: What protection and compensation must be available to individual purchasers when a manufacturer breaches EU rules concerning vehicle approval and prohibited defeat devices?

Decision: The Court addressed the right to adequate compensation, the conditions under which a manufacturer might be exempt from liability, and the principles governing the calculation of compensation.

Legal principle: EU vehicle-approval legislation may protect individual purchasers in ways that support civil claims against manufacturers, and national rules must respect the applicable requirements of EU law.

Application to autonomous transport: The case is not about autonomous driving, but it is highly relevant to the relationship between vehicle-safety legislation and private remedies. It illustrates how regulatory requirements may contribute to the legal foundation for a purchaser's claim against a vehicle manufacturer.

Comparative significance: The decision demonstrates the interaction between harmonised EU regulatory law and national civil-liability rules, particularly where vehicle manufacturers breach statutory requirements.

8. Comparative lessons from the case law

The cases reveal several principles that can guide the development of autonomous transport regulation.

The key limitation is that these cases do not establish a single universal liability regime for autonomous vehicles. Each jurisdiction must determine how traditional legal principles interact with the technical and operational characteristics of automated driving.

9. Allocation of liability in autonomous transport accidents

Consider a hypothetical collision involving a driverless taxi. The vehicle fails to recognise a pedestrian at a crossing and causes serious injury.

The potential legal analysis may proceed as follows.

Step 1 — Identify the immediate cause

Examine sensor data, software logs, system alerts, braking records, vehicle condition and road conditions.

Step 2 — Identify the relevant duty

Determine whether the manufacturer, software provider, fleet operator, maintenance contractor or another party owed a relevant legal duty.

Step 3 — Establish breach and causation

Determine whether a defect, negligent act, contractual breach or regulatory violation contributed to the injury.

Step 4 — Identify available compensation

Consider compulsory insurance, statutory compensation, product-liability remedies, negligence claims and contractual remedies.

Step 5 — Allocate responsibility

Apply the jurisdiction's rules on causation, contributory negligence, apportionment, statutory liability and recovery between responsible parties.

The injured pedestrian should not necessarily have to prove which line of software code failed before obtaining compensation. Where the legal system provides a direct claim against an insured vehicle operator or a statutory compensation route, that route may be available independently of a final determination of fault between the manufacturer and operator.

However, whether such a route exists, and whether it operates on a strict-liability basis, depends on the applicable jurisdiction and statutory conditions.

10. Major regulatory challenges

A. Identifying the legally responsible operator

Traditional transport laws often assume that a human driver controls the vehicle. Autonomous systems complicate that assumption because the person inside the vehicle may not be driving, or there may be no person inside it at all.

Legislation therefore needs to distinguish between the vehicle owner, the person or entity responsible for its operation, the manufacturer and any designated remote supervisor.

B. Technical evidence and transparency

Autonomous vehicles generate extensive data about their surroundings, decisions and operational state. Such records may be crucial to determining liability.

Effective regulation should address data preservation, access by investigators and courts, cybersecurity, privacy protection and the reliability of technical evidence.

C. Product defects and software updates

A vehicle may be safe when first sold but become unsafe because of a later software update, faulty maintenance or incompatibility between components.

Regulatory systems must determine when a change creates a new safety risk, which party must assess it and whether a recall or operational restriction is required.

D. Insurance and compensation

Compulsory insurance systems were generally developed around conventional vehicle use. Autonomous transport may require clearer rules for determining coverage, processing claims and recovering costs from manufacturers or other responsible parties.

E. Cross-border consistency

A vehicle may be manufactured in one country, use software developed in another and operate in a third. Divergent safety approvals, liability rules and insurance requirements can complicate compensation and enforcement.

International harmonisation can improve consistency, although national laws will continue to play an important role in many private-law disputes.

11. Future developments in autonomous transport governance

International regulatory work is increasingly focused on harmonised safety requirements for automated driving systems. The United Nations Economic Commission for Europe (UNECE) adopted a global regulatory framework for fully automated driving systems in June 2026, alongside related developments in vehicle regulations.

This development reflects a broader movement towards safety-management systems, structured validation, monitoring of vehicles in service and internationally consistent approval requirements.

Three priorities are particularly important for future legal reform:

Clear operational responsibility: legislation should identify who is responsible for safe deployment and operation when no human driver continuously controls the vehicle.

Effective compensation: accident victims should have practical access to insurance and legal remedies, with appropriate mechanisms for resolving disputes between responsible parties.

Adaptable safety regulation: regulatory requirements should address software updates, cybersecurity, system failures and new forms of automated mobility without depending entirely on assumptions designed for conventional vehicles.

12. Conclusion

Comparative autonomous transport regulation demonstrates that technological innovation requires corresponding development in safety standards, civil liability, insurance and regulatory oversight.

Australia combines vehicle-safety regulation, state and territory road laws, insurance schemes and common-law liability. The European Union uses harmonised vehicle-approval and product-liability rules alongside national civil-law systems. The United States combines federal vehicle-safety oversight with substantial state-level variation in negligence and product-liability law. Germany and France illustrate how civil-law codes and specialised legislation can address the risks created by autonomous transport.

The cases discussed above provide important legal foundations for evaluating product defects, negligence, causation, economic loss, insurance and remedies for regulatory breaches. They must nevertheless be applied carefully: traditional vehicle-liability cases do not automatically resolve every question arising from autonomous systems.

The central principle is that the absence of continuous human driving does not eliminate legal accountability. A workable autonomous transport system must identify responsible parties, preserve reliable evidence, ensure adequate insurance, enforce safety standards and provide effective remedies to those harmed by defective or improperly operated technology.
