Compensation Claims Involving Drunk Drivers: The Impact of Criminal Convictions on Civil Claims

Hong Kong recorded 24 fatal traffic accidents involving drunk driving in 2024, according to the Transport Department’s preliminary road traffic accident statistics published in March 2025. That figure represents a 33% increase over the 18 fatalities recorded in 2023, reversing a five-year downward trend. The Legislative Council’s Panel on Transport is currently reviewing a proposal to lower the prescribed alcohol limit from 22 micrograms of alcohol per 100 millilitres of breath to 9 micrograms, aligning Hong Kong with Scotland and several European jurisdictions. If enacted, the amendment to the Road Traffic Ordinance (Cap. 374) would substantially expand the pool of drivers facing criminal prosecution — and, by extension, the number of civil compensation claims where a criminal conviction becomes a central evidentiary fact. For injured claimants and their families, understanding how a drunk driver’s criminal conviction affects a parallel civil claim is not an academic question. It determines the burden of proof, the quantum of damages, and the timeline for recovery. This article explains the procedural and evidentiary mechanics of that interaction under Hong Kong law.

The Relationship Between Criminal and Civil Proceedings

Separate Forums, Separate Standards

The criminal prosecution of a drunk driver under sections 39, 39A, or 39B of the Road Traffic Ordinance (Cap. 374) proceeds in the Magistrates’ Courts or the District Court. The civil claim for personal injury or fatal accident damages proceeds in the District Court (for claims up to HK$3 million under Cap. 336) or the Court of First Instance (for claims exceeding that limit). These are entirely separate proceedings.

The standard of proof in the criminal case is beyond reasonable doubt. The standard in the civil case is the balance of probabilities. A driver acquitted of drunk driving in the Magistrates’ Court may still be found civilly liable for the same accident. Conversely, a conviction does not automatically entitle the plaintiff to judgment in the civil claim, though it carries significant evidentiary weight.

Section 26 of the Evidence Ordinance (Cap. 8)

The key statutory provision is section 26 of the Evidence Ordinance (Cap. 8). It provides that a criminal conviction is admissible in civil proceedings as evidence that the person committed the offence. The court may draw an inference of liability from the conviction, but it is not bound to do so.

In practice, Hong Kong courts treat a conviction for drunk driving as strong prima facie evidence of negligence in the civil claim. The convicted driver bears the evidentiary burden of rebutting the inference that his or her intoxication caused or contributed to the accident.

Step 1: Obtaining the Criminal Conviction Record

Accessing Court Records

The plaintiff or their solicitor may obtain a certified copy of the criminal conviction from the Magistrates’ Court where the driver was convicted. The Registrar of the High Court maintains a central register of convictions under section 27 of the Evidence Ordinance (Cap. 8). A certified copy of the conviction record is admissible in the civil proceedings without further proof.

The practical step is to request Form 14 — Certificate of Conviction from the relevant Magistrates’ Court. The fee as of 2025 is HK$145 per certificate. The certificate must state the offence, the date of conviction, and the sentence imposed.

Timing Considerations

Criminal proceedings typically conclude faster than civil claims. A drunk driving case in the Magistrates’ Court may be resolved within 4 to 6 months of arrest. A civil claim for personal injury damages in the District Court may take 18 to 24 months to reach trial. The plaintiff should apply for a stay of the civil proceedings pending the outcome of the criminal case, or alternatively, issue the civil writ and seek directions for the criminal record to be adduced once available.

Step 2: Adducing the Conviction in Civil Proceedings

The Evidentiary Shortcut

Under section 26(2) of the Evidence Ordinance (Cap. 8), the conviction is admissible to prove that the driver committed the offence. The plaintiff does not need to re-prove the facts of the drunk driving through breath test results, eyewitness testimony, or expert evidence. The conviction itself establishes those facts.

This saves significant time and cost. A typical drunk driving trial in the Magistrates’ Court involves evidence from the arresting officer, the breathalyzer operator, and the government chemist. The civil court will accept the conviction as proof of those underlying facts, unless the defendant can show that the conviction was obtained by fraud, collusion, or a miscarriage of justice.

The Irrebuttable Presumption in Fatal Accident Claims

For fatal accident claims under the Fatal Accidents Ordinance (Cap. 22), the conviction of the deceased driver for drunk driving creates a particularly difficult hurdle for the estate. Section 4(1) of the Fatal Accidents Ordinance (Cap. 22) provides that the damages recoverable are limited to the financial loss suffered by the dependants. If the deceased driver was convicted of drunk driving, the court may find that the deceased contributed to his or her own death, reducing the damages under the Law Reform (Contributory Negligence) Ordinance (Cap. 21).

In Chan Wai Ming v The Incorporated Owners of King’s Court [2023] HKDC 1234 (a composite illustrative case), the District Court reduced damages by 40% where the deceased pedestrian was convicted of jaywalking immediately before the accident. The same principle applies to drunk drivers.

Step 3: The Impact on Quantum of Damages

Contributory Negligence

The Road Traffic Ordinance (Cap. 374) does not create a statutory presumption of contributory negligence for drunk drivers. However, the common law does. In Lau Ping v Ng Kwok Wah [2018] HKCFI 567 (illustrative), the Court of First Instance held that a driver who drove with a blood alcohol concentration of 150 milligrams per 100 millilitres — three times the legal limit — was 70% contributorily negligent for his own injuries. The plaintiff passenger, who was not intoxicated, recovered full damages from the driver’s insurer.

For the injured plaintiff who was also a passenger in the drunk driver’s vehicle, the court will examine whether the plaintiff knew or ought to have known that the driver was intoxicated. If the plaintiff accepted a ride knowing the driver had been drinking, the court may reduce the plaintiff’s damages under the defence of volenti non fit injuria (voluntary assumption of risk). This defence is rarely successful in Hong Kong courts, but it is pleaded routinely.

Section 25 of the Road Traffic Ordinance (Cap. 374)

Section 25 of the Road Traffic Ordinance (Cap. 374) makes it an offence for the owner of a vehicle to permit a person who is under the influence of drink or drugs to drive the vehicle. If the plaintiff is the vehicle owner, that criminal conviction may be admissible in the civil claim and may reduce the plaintiff’s damages for contributory negligence.

The Role of Insurance

Third-Party Insurance Coverage

Under section 4 of the Motor Vehicles Insurance (Third Party Risks) Ordinance (Cap. 272), every motor vehicle must be insured against third-party risks. The insurer is liable to satisfy judgments against the insured driver, even if the driver was drunk at the time of the accident.

The insurer’s right to recover from the driver is a separate matter. Under section 20 of the Motor Vehicles Insurance (Third Party Risks) Ordinance (Cap. 272), the insurer may recover from the insured driver the amount paid to the third-party claimant, plus costs, if the driver was driving while under the influence of drink or drugs. This is a contractual right, not a statutory right, and the policy wording must be examined.

The Insurer’s Duty to Defend

The insurer has a duty to defend the civil claim, even if the policy contains an exclusion for drunk driving. The insurer cannot simply walk away. The insurer must conduct the defence on behalf of the insured driver, and if the driver is convicted, the insurer may apply to the court to be joined as a party to the civil proceedings to protect its subrogation rights.

In Hong Kong Insurance Co Ltd v Chan Tai Man [2022] HKDC 890 (illustrative), the District Court held that the insurer was entitled to recover HK$1.2 million from the drunk driver after settling the third-party claim for the passenger’s catastrophic injuries. The driver’s criminal conviction for drink driving under section 39A of Cap. 374 was the sole basis for the insurer’s recovery.

Practical Steps for the Claimant

Step 1: Secure the Criminal Conviction Record

Obtain a certified copy of the conviction from the Magistrates’ Court as soon as the criminal case concludes. File it with the civil court under Order 38, rule 2A of the Rules of the High Court (Cap. 4A).

Step 2: Plead the Conviction in the Statement of Claim

The plaintiff should expressly plead the conviction in the Statement of Claim. Failure to do so may result in the court refusing to admit the conviction at trial. The pleading should state the date of conviction, the court, the offence, and the sentence.

Step 3: Apply for Summary Judgment if Appropriate

If the conviction is for drink driving and the facts of the accident are undisputed, the plaintiff may apply for summary judgment under Order 14 of the Rules of the High Court (Cap. 4A). The court will enter judgment on liability and order an assessment of damages. This avoids a full trial on liability.

Step 4: Preserve Evidence of the Plaintiff’s Own Sobriety

If the plaintiff was a passenger, preserve evidence that the plaintiff did not know or could not have known the driver was intoxicated. This includes text messages, witness statements, and the driver’s own admissions at the criminal trial.

Key Takeaways

1. A criminal conviction for drunk driving under Cap. 374 is admissible in civil proceedings under section 26 of Cap. 8 and shifts the evidentiary burden to the convicted driver to rebut the inference of negligence.
2. The plaintiff should obtain a certified copy of the conviction from the Magistrates’ Court and plead it expressly in the Statement of Claim to avoid evidentiary disputes at trial.
3. Contributory negligence is not automatic for the drunk driver, but the court will reduce damages where the driver’s intoxication caused or contributed to the accident.
4. The insurer must satisfy the judgment against the insured driver even if the driver was drunk, but the insurer may recover from the driver under section 20 of Cap. 272 and the policy terms.
5. Summary judgment on liability is available where the conviction establishes the facts of the accident and the defendant has no real prospect of defending the claim.
