Traffic Accident Compensation & Diminished Value in Turkey

Home  /  Announcements  /  Traffic Accident Compensation

Traffic accidents are one of the most common sources of compensation claims in Turkey. After an accident, the affected party is entitled to claim not only repair costs but also diminished vehicle value, loss of use, loss of income while the vehicle is off the road, and any personal injury damages. This article outlines the compensation items available under Turkish law, the MTPL insurance application procedure, and the relevant time limits.

Legal Framework

Tort liability arising from traffic accidents is primarily governed by Highway Traffic Law No. 2918 (KTK) and the tort provisions of the Turkish Code of Obligations No. 6098 (especially Art. 49 and following). Insurance disputes are further regulated by Insurance Law No. 5684 and its implementing regulations.

Compensation Items

Damages from a traffic accident are generally divided into pecuniary (material) and non-pecuniary (moral) compensation. The most common pecuniary items are:

Where there is bodily injury, additional claims include medical expenses, temporary or permanent loss of earning capacity, damages for the impairment of economic future, and — for the relatives of those who lose their lives — damages for loss of support.

Diminished Vehicle Value

Diminished value is the most frequently asked question and the most commonly claimed item. No matter how skilfully the repair is carried out, a vehicle that has been involved in a traffic accident is worth less on the second-hand market than an undamaged equivalent. That gap is the diminished value claim.

When can diminished value be claimed?

Where is the claim filed?

Diminished value is claimed against the at-fault driver's Compulsory Motor Third Party Liability Insurance (in Turkish, trafik sigortası or ZMSS). The procedure is as follows:

  1. Written application to the insurer: A written claim is submitted to the at-fault party's MTPL insurer with the accident report, vehicle registration, driver's licence, damage photographs, repair invoice and bank account (IBAN) details. The insurer must respond within 15 business days (Insurance Law Art. 30/13).
  2. Insurance Arbitration Commission: If the insurer rejects the claim, accepts only part of it, or fails to respond within 15 business days, the claimant may apply to the Insurance Arbitration Commission (Sigorta Tahkim Komisyonu). Arbitration is faster than court proceedings and is conducted by arbitrators experienced in insurance matters.
  3. Civil court: Where arbitration is not used or the claimant prefers, an action may be filed in the competent Civil Court of First Instance or Commercial Court.

Important note: The initial written application to the insurer is mandatory — both to interrupt the limitation period and to gain access to the Insurance Arbitration Commission. You cannot go directly to arbitration without first applying to the insurer.

If the at-fault Driver Has No Insurance: The Guarantee Fund

If the at-fault driver did not hold valid MTPL insurance, or if the insurer cannot be identified, the injured party may claim compensation from the Guarantee Fund (Güvence Hesabı), a public fund established under Art. 91 of Law No. 2918. The Guarantee Fund processes applications similarly to insurance companies.

Non-Pecuniary Damages

In accidents involving bodily injury or loss of life, the victim or their relatives may also seek non-pecuniary damages under Art. 56 of the Turkish Code of Obligations. The judge will consider fault percentages, the severity of pain and suffering, the parties' economic circumstances and the specific facts of the case. Non-pecuniary damages are not covered by MTPL insurance and must be claimed directly from the at-fault driver or vehicle keeper.

Time Limits

Article 109 of the Highway Traffic Law sets out a special limitation regime for traffic accident claims:

Antalya's heavy tourism traffic, frequent rental car use and the presence of foreign-plated vehicles create some accident scenarios that need special attention:

Frequently Asked Questions

I'm not at fault, but the insurer refuses to pay diminished value. What can I do?

Document the written claim, wait for the 15 business day deadline, then file with the Insurance Arbitration Commission. Because diminished value is calculated by an independent expert, the arbitration figure is often considerably higher than the insurer's initial offer.

What's the difference between MTPL insurance and Kasko (collision)?

MTPL (ZMSS) is mandatory and covers damages caused to third parties; it does not cover damage to the policyholder's own vehicle caused by their own fault. Kasko is optional collision/comprehensive cover that, depending on its terms, will pay for damage to the policyholder's own vehicle even if they are at fault. Diminished value is claimed against the at-fault driver's MTPL insurer.

My vehicle was written off — what can I claim?

If the repair cost exceeds the vehicle's market value, the vehicle is treated as a total loss (pert). In that case, instead of the repair cost, the claimant may recover the vehicle's market value at the date of the accident, less salvage value. A diminished value claim is generally not available for written-off vehicles.

The at-fault driver was unlicensed or under the influence — will the insurance still pay?

The MTPL insurer continues to pay damages owed to third parties. However, the insurer can later recover (subrogate) what it paid from the at-fault driver. The injured party does not lose their claim because of the at-fault driver's misconduct.

What if no police report was filed?

For property-damage-only accidents, the parties may complete a private accident report themselves, provided both parties sign it accurately. If the other party refuses to sign, the traffic police or gendarmerie should be called immediately. Without a report, recovery becomes harder but not impossible — photographs, witness statements and expert evaluation can also establish how the accident occurred.
