Why a Korean commercial truck comparison should start with written quotes
A Korean commercial truck premium is not determined by payload alone. Vehicle construction, cargo, licensed use, driver scope, claims history, operating area, bodily and property limits, cargo liability, own-damage cover, and each provider’s underwriting rules can all change the final amount.
This calculator therefore does not invent a national average, a vehicle coefficient, or an insurer rate. It accepts up to three actual written quotes from insurance companies, the Korean freight mutual-aid system, or another mutual-aid provider. It annualizes different quote periods, adds separately stated cover, dues, fees, and payment costs, then subtracts only a confirmed discount or refund.
The result shows annual, monthly, daily, and per-10,000-km cost. A common hypothetical repair also exposes the cash difference between quoted own-damage deductibles and a quote with no own-damage cover. Price becomes a recommendation only after compulsory cover, quote conditions, and the compared coverage terms are aligned.
The comparison rule
- Use only amounts copied from a written quote
- Convert a 1-to-36-month quote to a 12-month planning amount
- Keep a compulsory-cover gap out of the price recommendation
- Label a cheaper but different policy as a raw lowest cost
- Do not score insurer and mutual-aid service or financial strength
Korea-specific jurisdiction and rule date
Based on current South Korean rules checked July 27, 2026
This English page is for a Korea-licensed freight transport operator or freight transport franchise operator. It is not a general insurance calculator for another country, a private-use truck, or a forwarding-only business. Korean won, metric tonnes, Korean compulsory motor cover, and Korean cargo-liability rules control the statutory checklist.
2026 compulsory motor coverage for a commercial freight vehicle
On July 27, 2026, the National Law Information Center OPEN API returned the current Automobile Accident Compensation Security Act as MST 277017 and its Enforcement Decree as MST 284827. Act Article 5 requires compulsory bodily cover and property cover. Article 5(3)(3) also places licensed freight transport and freight franchise operators within the commercial-vehicle additional bodily-cover rule. Act Article 8 prohibits road operation of a vehicle without the required compulsory insurance.
South Korean 2026 compulsory commercial truck motor and cargo coverage screen| Check | Verified 2026 threshold | Calculator treatment |
|---|
| Bodily Liability I | Compulsory insurance or equivalent mutual aid included | User confirms inclusion |
| Additional commercial bodily | At least 100,000,000 KRW per victim or all loss | User selects fixed minimum or unlimited |
| Property damage | At least 20,000,000 KRW per accident | Entered limit is compared with the threshold |
| Cargo liability when required | At least 20,000,000 KRW per accident | Weight, vehicle type, and exclusion are screened first |
Additional bodily cover is separate
Decree Article 4 defines the amount above basic compulsory cover as at least KRW 100 million per victim or all loss suffered by the victim. Selecting the fixed or unlimited option means that the user has checked the actual written quote. The calculator does not interpret policy text.
Bodily Liability I is an inclusion check
Decree Article 3 connects compulsory bodily payments to death, injury, disability, and injury-grade schedules. This comparison does not turn those schedules into a score. It only records whether Bodily Liability I or equivalent compulsory mutual aid is included.
When does the Korean cargo-liability requirement apply?
The current Trucking Transport Business Act, MST 286393, Article 35 covers a designated freight vehicle when its maximum payload is at least 5 tonnes or its gross weight is at least 10 tonnes. The boundaries are inclusive: exactly 5 tonnes or exactly 10 tonnes reaches the weight test.
The current Enforcement Decree, MST 286309, Article 9-7 requires a transport operator to carry at least KRW 20 million per accident for each covered vehicle. The calculator does not apply the separate KRW 5 million rule for a forwarding business that only arranges household-goods moves, because that is outside this vehicle-owner comparison.
Screening formula
Weight test = maximum payload ≥ 5 t OR gross weight ≥ 10 t
Cargo duty = weight test AND listed vehicle type AND no confirmed exclusion
Coverage screen = at least 20,000,000 KRW per accident
The current Enforcement Rule, MST 282123, Article 41-13 lists general, van-type, and special-purpose freight vehicles plus towing special vehicles. It also excludes specified vehicles carrying economically valueless construction waste or refuse, certain sub-5-tonne vehicles whose gross weight reached 10 tonnes because an emissions-reduction device was attached, and trailers within the special-purpose freight category.
A lighter truck still needs motor cover
A 1-tonne commercial truck may not trigger this automatic Article 35 cargo screen, but Bodily Liability I, additional commercial bodily cover, and property cover remain separate obligations. A shipper, platform, or transport contract may also require cargo cover beyond the statutory screen. A not-triggered result is not advice to remain uninsured.
How the quote-period and annual cost are calculated
The quote-period gross cost is the written premium or mutual-aid contribution plus separately stated cargo cover, dues, fees, and installment or payment cost. A confirmed credit is capped at that gross amount so the net cost cannot become negative.
Net quote-period cost
Written premium + separate cover, dues, and fees + installment and payment cost − applied confirmed credit.
Annualized planning cost
Round the net quote-period cost × 12 ÷ quote-period months to the nearest won. This is a proportional comparison, not an insurer short-rate or a renewal forecast.
Common own-damage repair scenario
For a quote with own-damage cover, the calculator multiplies the common repair amount by the entered deductible rate and keeps the result between the entered minimum and maximum. Without own-damage cover, the whole repair scenario is shown as out-of-pocket. This is not a claim settlement or a probability-weighted expected loss.
3,000,000 KRW repair × 20% = 600,000 KRW
With a 200,000 KRW minimum and 500,000 KRW maximum, the displayed deductible is 500,000 KRW
Step-by-step workflow
- Read the registration certificate
Enter maximum payload and gross vehicle weight in metric tonnes, then confirm the listed vehicle type and any statutory exclusion. - Set one distance and repair scenario
Every quote must use the same annual distance and hypothetical repair amount for the unit-cost and deductible comparison to be meaningful. - Copy every written cost once
Enter the base premium, separate cover or dues, payment cost, and only a confirmed credit. Avoid deducting a fee twice when the stated premium is already net. - Match compulsory and optional coverage
Check bodily, property, cargo, own-damage, and deductible terms directly against each written quote or policy summary. - Confirm like-for-like conditions
Align vehicle, commercial use, driver scope, effective date, and riders. Only then treat the lowest annualized cost as a recommendation.
Worked example: a 12-month insurer quote and a 6-month mutual-aid quote
The following amounts are fictional test inputs, not a Korean market price. Assume a listed vehicle with a 5-tonne maximum payload and 10.5-tonne gross weight, 60,000 km per year, and a 3,000,000 KRW repair scenario. Both quotes include Bodily Liability I, unlimited additional bodily cover, 200,000,000 KRW property cover, 20,000,000 KRW cargo cover, and own-damage terms of 20% with a 200,000 KRW minimum and 500,000 KRW maximum.
Fictional Insurer A and Freight Mutual Aid B annualized quote example| Item | Fictional Insurer A | Fictional Freight Mutual Aid B |
|---|
| Quote period | 12 months | 6 months |
| Base written amount | 2,400,000 KRW | 1,150,000 KRW |
| Combined added cost | 150,000 KRW | 70,000 KRW |
| Confirmed credit | 100,000 KRW | 20,000 KRW |
| Annualized cost | 2,450,000 KRW | 2,400,000 KRW |
| Monthly equivalent | 204,167 KRW | 200,000 KRW |
| Cost per 10,000 km | 408,333 KRW | 400,000 KRW |
| Annual cost plus one repair | 2,950,000 KRW | 2,900,000 KRW |
Insurer A has a 2,450,000 KRW net 12-month cost. Mutual Aid B has a 1,200,000 KRW net six-month cost, which annualizes to 2,400,000 KRW. With all coverage and deductible terms aligned, B is 50,000 KRW lower per year. If B instead carries a lower property limit or different own-damage terms, the interface removes the recommendation label and shows only a raw lowest amount.
How to interpret the result
Annualized does not mean the next renewal price
A short quote is scaled proportionally. The calculation does not predict short-rate treatment, a future claim surcharge, seasonal operation, or the next underwriting decision.
Statutory minimum is not automatically sufficient cover
KRW 20 million for property or cargo is a legal screening boundary used here. High-value cargo, a multi-vehicle loss, refrigerated transport, or contract liability may justify a much higher limit.
Provider labels do not make contracts equivalent
An insurance policy and freight mutual-aid rules can differ in exclusions, permitted drivers, accident handling, own-damage settlement, and service. Compare the actual clauses, not only premium versus contribution.
Treat a conditional credit conservatively
A mileage, safe-driving, or loss-free benefit should remain zero until its eligibility and amount are confirmed. The comparison caps an entered credit at gross quote-period cost.
Practical use cases
- One-tonne individual operator
The Article 35 cargo weight screen usually does not trigger, but basic and additional bodily cover plus property cover still need confirmation, and the shipper contract may impose separate cargo requirements - Five-tonne general freight vehicle
Exactly 5 tonnes reaches the maximum-payload boundary, so the screen checks each vehicle quote for at least KRW 20 million of cargo liability - Tractor or towing special vehicle
Confirm the towing vehicle type and gross weight without confusing the special-purpose trailer exclusion with the powered tractor - Insurance company versus freight mutual aid
Add dues and separately charged cargo cover, align liability and own-damage terms, then compare net annual outlay - Temporary fleet expansion
Annualize a three- or six-month quote for scale, while checking the actual short-term and cancellation rules in the provider document
Documents to prepare and common mistakes
Prepare these records
- Registration certificate vehicle type, payload, and gross weight
- Business permit, licensed use, and actual cargo category
- Driver scope, experience, and claims-history assumptions
- Written quotes using the same policy start date
- Each limit, exclusion, deductible rate, minimum, and maximum
- Separate cargo premium, dues, fees, and payment terms
Avoid these comparison errors
- Adding cargo cover again when it is already in the base quote
- Comparing six-month and twelve-month totals without annualizing
- Treating KRW 200 million and KRW 1 billion property limits as equal
- Subtracting a conditional credit as if it were already approved
- Showing zero repair exposure for a quote with no own-damage cover
- Treating the statutory minimum as complete business-risk protection
Frequently asked questions
Is an insurer or freight mutual-aid association always cheaper?
No. Vehicle, driver, cargo, coverage, dues, installment terms, and underwriting differ. Obtain written like-for-like quotes and compare the complete cost and wording.
Does a one-tonne commercial truck need no cargo insurance?
It normally falls below the automatic 5-tonne and 10-tonne Article 35 screen, but a transport or shipper contract may require cargo cover. Compulsory motor bodily and property cover remain separate.
Does exactly five tonnes trigger the cargo screen?
Yes, when the vehicle is within the listed types and no statutory exclusion applies. The Korean text uses at least, so exactly 5 tonnes is included.
What if only gross weight reaches ten tonnes?
Gross weight of exactly 10 tonnes satisfies the weight test even when maximum payload is below 5 tonnes. Check the emissions-device exception and other Article 41-13 exclusions separately.
Are KRW 20 million property and cargo limits enough?
They are statutory screening boundaries in this tool, not a conclusion that business risk is adequately insured. Cargo value, contract liability, accident severity, and exclusions may justify higher limits.
Is doubling a six-month quote the actual one-year premium?
No. It is a proportional comparison amount. It does not reproduce a provider’s short-rate table, cancellation refund, renewal review, or claim surcharge.
Why is the cheapest quote not labeled recommended?
There may be fewer than two active quotes, a compulsory-cover gap, unconfirmed like-for-like conditions, or different coverage and deductible terms. The tool can still show the raw lowest amount, but it reserves the recommendation label until the comparison is aligned.
