Is Kasko (Comprehensive Insurance) Mandatory? How It Differs From Traffic Insurance
The short answer to "will I be fined if I don't get Kasko?" is no — there is no law that makes Kasko (Turkey's comprehensive/collision car insurance) mandatory. But that doesn't mean Kasko is never a "must": if you bought your car with a bank loan or through financial leasing, Kasko can effectively become part of the contract. In this article we explain why Kasko is an optional type of insurance, how it differs from Zorunlu Trafik Sigortası (mandatory traffic/third-party liability insurance), and when Kasko really becomes unavoidable.
Kasko is an optional type of insurance
Kasko is a contract freely entered into between an insurance company and a vehicle owner; it is regulated under the Kara Araçları Kasko Sigortası Genel Şartları (General Conditions for Land Vehicle Kasko Insurance), and in the sector's own regulatory classification it falls under "Property Insurance" ("Mal Sigortaları"), not "Liability Insurance" ("Sorumluluk Sigortaları") (SEDDK — Turkey's Insurance and Private Pension Regulation and Supervision Agency). This classification matters, because Kasko arises not from any legal obligation but from your own wish to transfer the risk of damage to your vehicle to the insurance company. Under the General Conditions, Kasko covers material damage arising from the vehicle's collision, striking a fixed or moving object, overturning, catching fire, or being stolen/an attempted theft (TSB — the Insurance Association of Turkey) — but obtaining this coverage is not made compulsory by any statutory provision. We covered exactly how far Kasko coverage extends, the distinction between limited/extended/full Kasko, and optional add-on coverages in detail in our Kasko types article.
The core difference from mandatory traffic insurance
The fact that Kasko is optional is the most fundamental point that separates it from mandatory traffic insurance. The legal basis for Zorunlu Trafik Sigortası (the Compulsory Motor Vehicles Third-Party Liability Insurance, "Karayolları Motorlu Araçlar Zorunlu Mali Sorumluluk Sigortası") is Article 91 of the Highway Traffic Law No. 2918 ("Karayolları Trafik Kanunu"); this article explicitly states that "operators ... are required to obtain liability insurance" and provides that vehicles without valid coverage will be barred from traffic. Traffic insurance covers damage to the other party (third parties) in an accident, not damage to your own vehicle — this distinction is also spelled out explicitly in the General Conditions (mevzuat.gov.tr). Kasko fills exactly this gap: it lets you optionally transfer the damage to your own vehicle to the insurance company. We won't repeat here the line-by-line table comparing the scope of the two policies, their effect on vehicle inspection, and the consequences of not having them; you can find that full comparison in our Traffic insurance vs. Kasko article.
When does Kasko actually become necessary?
Even though no provision makes Kasko legally mandatory, two financing models can make it effectively unavoidable in practice:
Vehicle loan (car-pledge loan). If you buy your car with a bank loan and the vehicle is pledged as collateral for that loan, banks may require, as a contractual condition for the life of the loan, that you maintain a Kasko policy — because the pledged vehicle is the loan's collateral, and damage to it weakens the bank's security as well. This is an obligation arising from the loan contract, not from a statutory provision; the condition and its duration vary from bank to bank and from contract to contract. In practice this condition typically works as follows: proof of a Kasko policy is requested when the loan application is approved, the policy is expected to be kept in force without interruption for the life of the loan, and the pledge remains on the vehicle until the loan is fully paid off. If your Kasko policy is not renewed when it expires, this can be treated as a breach of the loan agreement; the sanction the bank applies in response (a warning, renewing the policy itself and charging you, accelerating the loan, etc.) again depends on the terms of that specific contract and does not work the same way at every bank. So on a pledged vehicle, tracking the Kasko renewal date is not just about protecting the car — it also means fulfilling an obligation under the loan agreement.
Financial leasing. Here the situation is partly grounded in statute: the fourth paragraph of Article 24 of Law No. 6361 on Financial Leasing, Factoring and Financing Companies ("Finansal Kiralama, Faktoring ve Finansman Şirketleri Kanunu") states that "the leased asset is required to be insured"; who insures the asset is determined in the contract, and the premiums are paid by the lessee. The law does not name "Kasko" here — it speaks generally of "insurance" — but when the asset in question is a vehicle, the product that secures the vehicle's own body against collision, fire, or theft is, in effect, Kasko; so on a vehicle acquired through leasing, Kasko practically becomes an unavoidable expense for the life of the contract. The fifth paragraph of the same article adds that liability for damage to and loss of the asset during the contract term belongs to the lessee, limited to the portion not covered by the insurance payout received — meaning that insufficient Kasko coverage leaves the lessee bearing the risk of paying the excess out of pocket.
Who does Kasko actually make sense for?
Even without a loan or leasing requirement, Kasko is a sensible choice for many vehicle owners. If your vehicle's market value is high, if it's new or relatively new, and if you don't want to pay repair costs out of pocket in a single-vehicle accident (for example, hitting a fixed object) where traffic insurance won't cover it even if you're not at fault, Kasko is the way to transfer that risk to the insurance company. Kasko is also practically "necessary" for vehicles driven daily in heavy city traffic, parked in areas with a high theft risk, or still under a loan/pledge that hasn't been paid off. On the other hand, for an older, low-value vehicle, the Kasko premium can sometimes approach the likely damage amount; in that case the cost-benefit calculation varies from person to person.
There are a few concrete criteria to look at when making this decision: the vehicle's current used-market value (the lower the value, the lower Kasko's return), the premium difference between deductible and non-deductible coverage options, and how much your no-claims history can bring the premium down. We covered, in full, why the Kasko premium varies this much from company to company for the same vehicle, which factors determine the price, and concrete ways to lower the premium, in our Kasko prices 2026 article.
In summary
Kasko is a type of insurance that exists by contract, not by law; there is no administrative penalty for not getting it, and it does not substitute for traffic insurance — the two protect against separate risks. On a vehicle bought outright, without a loan, Kasko is entirely your own choice; on a vehicle acquired through a vehicle loan or financial leasing, Kasko can become effectively mandatory because of the bank's or leasing company's contractual condition, or the insurance obligation set out in law. Whichever category your vehicle falls into, knowing your policy's expiry date is always your own responsibility — insurance companies may neglect to send reminders, and even a single day's delay leaves any damage that occurs that day uncovered.
