How Is Traffic Accident Compensation Calculated in Hong Kong? Pain and Suffering and Loss of Earnings Explained

Hong Kong’s traffic accident compensation framework is facing renewed scrutiny in 2025, as the Transport and Logistics Bureau pushes ahead with its review of the Third Party Risks Insurance Ordinance (Cap. 272) and the minimum third-party liability insurance coverage for motor vehicles. The current minimum cover of HKD 100 million for property damage and unlimited liability for personal injury has been in place since 2019, but rising medical costs and a 2024 Court of Appeal judgment on non-pecuniary damages have prompted calls for a structured revision of the “general damages” tariff for pain, suffering, and loss of amenity (PSLA). For the estimated 15,000 persons injured in traffic collisions annually — according to Transport Department figures for 2023 — understanding how compensation is calculated is not an academic exercise. It determines whether a settlement offer is fair, whether litigation is worthwhile, and whether future loss of earnings is properly accounted for. This article sets out the statutory framework, the two main heads of damage, and the practical steps a claimant should expect.

The Legal Framework for Traffic Accident Compensation in Hong Kong

The primary cause of action in a traffic accident claim is the tort of negligence. The claimant must prove, on a balance of probabilities, that the defendant driver owed a duty of care, breached that duty, and that the breach caused the claimant’s injuries and quantifiable losses. The court applies the same principles as in any personal injury claim, but the Road Traffic Ordinance (Cap. 374) and the Third Party Risks Insurance Ordinance (Cap. 272) impose specific obligations on drivers and insurers.

Step 1: Establishing Liability and the Role of the Police Report

The first procedural step is to secure a police report. Under the Road Traffic Ordinance (Cap. 374, s. 56), any driver involved in an accident causing injury must stop, provide particulars, and report the accident to the police within 24 hours. The police report, while not conclusive evidence of liability, is admissible in civil proceedings and is routinely relied upon by insurers when assessing claims. A police report that records a driver being issued a fixed penalty notice for careless driving (Cap. 374, s. 38) significantly strengthens the claimant’s position on liability.

The claimant should also preserve evidence: photographs of the scene, vehicle damage, and injuries; witness contact details; and medical records from the accident and emergency department. The limitation period for a personal injury claim arising from a traffic accident is three years from the date of the accident (Limitation Ordinance, Cap. 347, s. 27). Failing to issue a writ within that period bars the claim unless the court exercises its discretion under s. 30 of the same Ordinance.

Step 2: The Two Heads of Damage – General and Special Damages

Hong Kong law divides compensation into two categories. General damages compensate for non-pecuniary loss: pain, suffering, and loss of amenity (PSLA). Special damages compensate for pecuniary loss: past and future loss of earnings, medical expenses, travel costs, and other out-of-pocket expenses.

The court assesses general damages by reference to the “PSLA tariff” — a set of judicial guidelines published by the Judiciary’s Personal Injuries (Lump Sum) Board. The tariff is updated periodically. The most recent published version is the 2023 Guidelines, which set out bands of damages for specific injury types. For example, a moderate whiplash injury to the cervical spine falls within the HKD 80,000 to HKD 180,000 band. A severe traumatic brain injury with permanent cognitive deficit can attract HKD 1,500,000 to HKD 4,000,000. These figures are not statutory; they are indicative. The court retains discretion to depart from the tariff where the facts justify it.

Special damages must be pleaded with particularity. The claimant must provide documentary proof of all losses: wage slips, tax returns, medical invoices, and receipts for medication and transport. The court will not award special damages that are pleaded in a vague or unsubstantiated manner.

Calculating Pain and Suffering (PSLA) Damages

PSLA damages are the most contested head of claim in traffic accident litigation. The assessment is fact-sensitive and turns on the severity, duration, and permanence of the injury.

The PSLA Tariff and How It Is Applied

The court applies the tariff by first classifying the injury into one of the categories set out in the 2023 Guidelines. The categories cover: head and brain injuries; spinal injuries; upper and lower limb injuries; psychiatric injuries; and soft tissue injuries (whiplash, sprains, contusions). Each category has sub-categories based on severity (mild, moderate, severe, very severe) and duration (transient, short-term, long-term, permanent).

For a claimant with a moderate soft tissue injury to the lumbar spine that resolves within six months, the tariff suggests a PSLA award in the range of HKD 50,000 to HKD 120,000. If the same injury causes chronic pain persisting beyond two years, the award moves into the “moderate-to-severe” band of HKD 180,000 to HKD 350,000.

The court also considers the claimant’s age, pre-existing condition, and the impact on lifestyle. A younger claimant with a longer life expectancy and greater loss of amenity may receive a higher award within the same band. A claimant with a pre-existing degenerative condition that was asymptomatic before the accident may receive a reduced award if the court finds the accident merely accelerated the onset of symptoms — applying the “thin skull” rule (the defendant takes the victim as they find them) but not the “crumbling skull” rule (the court discounts damages to reflect the pre-existing vulnerability).

The Role of Medical Expert Evidence

PSLA damages cannot be assessed without a medical report. The court requires a report from a qualified specialist — usually an orthopaedic surgeon, neurologist, or psychiatrist — that sets out:

• The diagnosis and prognosis
• The degree of permanent impairment (expressed as a percentage, using the American Medical Association’s Guides to the Evaluation of Permanent Impairment, 6th Edition)
• The effect on daily activities, work capacity, and leisure
• The need for future medical treatment or rehabilitation

The report must be served on the defendant’s insurer at least 28 days before trial (Order 38, rule 2A of the Rules of the High Court, Cap. 4A). If the claimant fails to serve a medical report, the court may refuse to admit it, or may adjourn the trial with costs.

Calculating Loss of Earnings and Future Earning Capacity

Loss of earnings is the second major head of damage. It is divided into past loss (from the date of accident to the date of trial or settlement) and future loss (from the date of trial or settlement to the date of retirement or expected cessation of work).

Past Loss of Earnings: The Multiplier-Multiplicand Approach

The court calculates past loss of earnings by applying a simple formula: the claimant’s pre-accident net monthly income multiplied by the number of months of absence from work. The claimant must prove the pre-accident income with documentary evidence: salary slips, tax returns (the Inland Revenue Department’s tax assessment notice), and employer’s confirmation letter.

If the claimant was self-employed, the court will look at the average net profit for the three years preceding the accident, as declared to the Inland Revenue Department. The court may discount this figure if the income was volatile or if the claimant’s business was seasonal.

The claimant must also prove that the absence from work was caused by the accident and not by an unrelated condition. If the claimant suffered a mild whiplash injury but was already on sick leave for a pre-existing back problem, the court may apportion the loss.

Future Loss of Earnings: The Multiplier Approach

Future loss of earnings is calculated using a multiplier. The multiplier represents the number of years the claimant would have worked but for the accident, discounted for contingencies (mortality, morbidity, unemployment) and accelerated receipt (the claimant receives a lump sum now instead of periodic payments over time).

The starting point is the claimant’s pre-accident net annual income. The court then applies a multiplier derived from the Ogden Tables (the actuarial tables published by the UK Government Actuary’s Department, adopted by Hong Kong courts). For a claimant aged 35 with a stable job and no pre-existing health issues, the multiplier for loss of earnings to age 65 is approximately 18 to 20. For a claimant aged 55, the multiplier drops to 8 to 10.

The court will reduce the multiplier if the claimant has a residual earning capacity — the ability to work in a different role or on a part-time basis. For example, a construction worker who suffers a leg injury that prevents him from working on scaffolding but can still work as a site supervisor may have a residual earning capacity of HKD 15,000 per month. The court will deduct that figure from the pre-accident income before applying the multiplier.

Loss of Earning Capacity (The “Smith v Manchester” Award)

If the claimant can return to work but is at a disadvantage in the open labour market — for example, a driver who loses a leg but can still work in an office job — the court may make a separate award for loss of earning capacity. This is known as a “Smith v Manchester” award, named after the English Court of Appeal case Smith v Manchester Corporation (1974). The award is a lump sum, typically between one and three years’ net income, designed to compensate for the risk of future unemployment or underemployment due to the injury.

The court will consider the claimant’s age, skills, the state of the labour market, and the likelihood of the claimant losing their current job and being unable to find equivalent work.

Practical Steps for Claimants and the Role of the Insurer

The process of claiming compensation is governed by the Personal Injuries (Lump Sum) Board’s procedural guidelines and the court’s case management powers.

Step 1: Notify the Insurer and Preserve Evidence

The claimant must notify the defendant driver’s insurer within 21 days of the accident. The insurer will appoint a loss adjuster who will investigate the accident, take statements, and obtain medical records. The claimant should cooperate but should not sign any document that admits contributory negligence or waives the right to claim.

The claimant should also preserve all evidence: photographs, witness contact details, medical records, and receipts. The court may draw an adverse inference if the claimant fails to preserve evidence that was within their control.

Step 2: Obtain Legal Advice and a Medical Report

The claimant should consult a solicitor who specialises in personal injury. The solicitor will arrange for a medical report, advise on the quantum of damages, and issue a letter of claim to the insurer. The Pre-Action Protocol for Personal Injury Claims (issued by the Judiciary in 2019) requires the claimant to send a letter of claim within 28 days of the accident, setting out the full details of the claim.

If the insurer admits liability, the parties will negotiate quantum. If they cannot agree, the claimant must issue a writ in the District Court (for claims up to HKD 3 million) or the Court of First Instance (for claims above HKD 3 million). The Small Claims Tribunal has no jurisdiction over personal injury claims.

Step 3: Consider Mediation and the Risks of Litigation

The court encourages mediation. The Practice Direction on Mediation (PD 31) requires the parties to consider mediation before trial. If a party unreasonably refuses to mediate, the court may impose costs sanctions even if that party wins at trial.

The claimant should also be aware of the risk of contributory negligence. If the claimant was partly at fault — for example, jaywalking or failing to wear a seatbelt — the court will reduce the damages by a percentage. The Road Traffic Ordinance (Cap. 374, s. 8) provides that failure to wear a seatbelt is contributory negligence, and the court may reduce damages by up to 25%.

Key Takeaways

• The PSLA tariff in the 2023 Guidelines provides indicative bands for pain and suffering damages; the court retains discretion to depart from them based on the severity and permanence of the injury.
• Past loss of earnings is calculated by multiplying the claimant’s pre-accident net monthly income by the months of absence; future loss is calculated using a multiplier derived from the Ogden Tables, discounted for residual earning capacity.
• The limitation period for a traffic accident personal injury claim is three years from the date of the accident; failing to issue a writ within that period bars the claim unless the court exercises its discretion.
• Medical expert evidence is mandatory for PSLA and loss of earnings claims; the report must be served at least 28 days before trial, or the court may exclude it.
• Mediation is strongly encouraged by the court; unreasonable refusal to mediate can result in adverse costs orders even if the refusing party wins at trial.
