Car Insurance in Thailand: Class 1/2/3 Costs for Foreigners
Compulsory car insurance in Thailand, called Por Ror Bor (พ.ร.บ.), costs about ฿600–800 a year (~$18–24) and every registered vehicle must carry it. That policy pays almost nothing toward your own car or a serious injury claim, which is why nearly everyone stacks a voluntary policy on top. Voluntary cover runs from roughly ฿1,950 for bare-bones Class 3 up to ฿15,000–20,000+ for full Class 1, and the class you pick has nothing to do with your nationality — it depends on your car's age, its value, and whether you hold a valid Thai driving license.
Quick answer
- Compulsory Por Ror Bor (CTPL): ฿600–800/yr for a car (~$18–24), commonly around ฿645
- Class 1 (comprehensive):
฿15,000–20,000+/yr ($455–606+), usually only for cars under 5–7 years old - Class 2+:
฿5,500–20,000/yr ($167–606), no own-damage cover unless a named third party is at fault - Class 3+:
฿5,000–7,000/yr ($152–212), collision cover but no theft/fire cover - Class 3 (third-party only):
฿1,950–15,000/yr ($59–455), cheapest legal option beyond the compulsory minimum - The one rule that trips up expats: drive without a valid Thai (or International) driving license and your voluntary policy can be treated as void in a claim
Compulsory insurance: Por Ror Bor (CTPL)
Every vehicle registered in Thailand must carry Por Ror Bor, the compulsory third-party liability policy, before it can be taxed and legally driven. It costs the same regardless of insurer, since the government sets both the price and the coverage — there's no shopping around here, only on the voluntary layer stacked on top.
| Vehicle type | Annual Por Ror Bor cost |
|---|---|
| Car / sedan | ฿600–800 (commonly ~฿645) |
| Pickup truck | ~฿900–1,100 |
| Motorbike | ฿160–645 depending on cc |

Por Ror Bor pays medical costs up to ฿80,000 per injured person and a death benefit of ฿300,000–500,000, but only for people outside your own car — pedestrians, other drivers, passengers in the other vehicle. It pays nothing toward your own car's repair and nothing toward your own injuries if you're the driver at fault. Driving without it is illegal and carries a fine up to ฿10,000, on top of whatever the accident itself costs you.
Voluntary insurance: what Class 1, 2+, 2, 3+ and 3 actually mean
Thai insurers sell five tiers of voluntary cover, and the naming is confusing on purpose — insurers use it to segment risk, not to make comparison easy. Here's what each class actually pays for.
| Class | Own car damage | Theft / fire | Third-party (other car/property) | Typical annual price |
|---|---|---|---|---|
| Class 1 | Yes, any accident, at fault or not | Yes | Yes | ~฿15,000–20,000+ ($455–606+) |
| Class 2+ | Only if a named third party is at fault | Yes | Yes | ~฿5,500–20,000 ($167–606) |
| Class 2 | No | Yes | Yes | Rarely sold as a standalone product now |
| Class 3+ | Only if a named third party is at fault | No | Yes | ~฿5,000–7,000 ($152–212) |
| Class 3 | No | No | Yes | ~฿1,950–15,000 ($59–455) |

Class 1 is the only tier that pays for your own car when the accident is your fault, or when there's no one else to blame — you reverse into a pole, a branch dents the roof. That blanket cover is why it costs three to ten times more than Class 3, and why most insurers only sell it on cars under roughly 5–7 years old; past that age, insurers either quote a steep premium or push you toward Class 2+ or 3+.
The gap between 2+/3+ and plain 2/3 is theft and fire cover. If your car parks on the street overnight, or you're worried about flood damage in rainy season, check that line item before downgrading to save money.
What foreigners can actually buy
There's a persistent myth that foreigners are locked out of Class 1 insurance in Thailand. Not true for the situation most expats are in. Buy or lease a car here and it gets Thai license plates, and Thai-plated vehicles are eligible for any class — 1 through 3 — regardless of the owner's nationality. The insurer prices on the car's age, value, and your driving record, not your passport. The restriction sometimes mentioned online (Class 1 for Thai-registered vehicles only, Class 3 as the only option for foreign-registered cars) is a narrow case: vehicles physically carrying foreign plates, such as cars driven across the border from Malaysia. Almost no expat living in Thailand is in that situation.
What genuinely matters is the driving license. Insurers routinely treat a voluntary policy as void in a claim if the driver didn't hold a valid Thai driving license, or a valid International Driving Permit alongside a foreign license, at the time of the accident. An expired IDP or a foreign license used well past the point you should have converted are the most common reasons a claim gets denied. Settling in for more than a few months? Get the Thai license first — it's the single biggest factor in whether the insurance actually pays out.
To buy a policy you'll typically need the car's registration book (เล่มทะเบียน), your passport photo page, your driving license, and — for Class 1 — photos of the car's four sides so the insurer can log existing damage before cover starts. Payment runs through a Thai bank card or transfer, one more reason to sort out a Thai bank account early if you plan to own a car here.
No-claim discount and the deductible trade-off
A no-claim year typically knocks 10–20% off next year's premium, compounding over consecutive claim-free years. Filing a small claim to dodge an out-of-pocket repair often costs more over two or three years than paying for the repair, so do the math before calling your insurer over a minor scrape. Most Class 1 policies also let you pick a voluntary excess, commonly ฿2,000–5,000 per claim, for a further 10–15% off — worth it if you're a careful driver with off-street parking.
Choosing a class in practice
A new or financed car almost always wants Class 1 — lenders often require it as a loan condition, and the payout on a total loss protects an asset you haven't finished paying off. A car three to seven years old that's paid off is the classic Class 2+ decision: skip cover for at-fault damage but keep theft, fire, and third-party protection, usually the largest realistic loss. An older, lower-value car you could replace in cash is where Class 3+ or 3 makes sense — you're insuring liability to other people, not a car whose repair bill might exceed its resale value.
Car insurance is priced separately from health insurance and from motorbike cover, which has its own pricing logic and its own license traps — a two-vehicle household is common here. Comparing Thai domestic insurers against international insurers is worth doing once too, since claims handling and English-language support vary more between companies than the headline price does.
Frequently Asked Questions
Is Por Ror Bor enough insurance for a car in Thailand?
No. It's compulsory and legally required, but it only covers injuries and deaths to people outside your own car, up to ฿80,000 medical and ฿300,000–500,000 death benefit per person. It pays nothing toward your own car's damage or your own injuries as the driver. Almost every car owner in Thailand stacks a voluntary Class 1–3 policy on top.
Can foreigners buy Class 1 car insurance in Thailand?
Yes, for any Thai-registered car — what most expats drive, since a car bought or leased here carries Thai plates. The Class-1-for-Thai-plates-only restriction that circulates online refers to foreign-plated vehicles crossing the border, not to foreigners owning a Thai-registered car. What matters more is a valid Thai driving license or International Driving Permit, since insurers can void a claim without one.
How much does full Class 1 car insurance cost in Thailand?
Roughly ฿15,000–20,000+ a year (~$455–606+) for a typical passenger car, depending heavily on make, model, age, and no-claim history. Insurers generally only offer Class 1 on cars under about 5–7 years old; older cars get pushed toward Class 2+ or 3+.
What's the difference between Class 2+ and Class 3+?
Both cover theft, fire, and third-party liability — Class 2+ adds cover for your own car when a named third party is at fault, while Class 3+ drops theft and fire cover and only adds collision in that same named-third-party scenario. Insurers use these labels slightly differently, so read the policy wording.
Does my car insurance still pay out if I'm driving on a foreign license?
It's genuinely risky. Insurers routinely deny claims when the driver held only an expired foreign license, no International Driving Permit, or a lapsed Thai license. If you're in Thailand more than a few months at a time, converting to a Thai driving license is what makes the actual policy enforceable.
The bottom line
Compulsory Por Ror Bor is cheap and mandatory but nowhere near enough — the government's minimum, not real coverage. Layer a voluntary Class 1, 2+, or 3+ policy on top based on your car's age and value, expect to pay anywhere from about ฿2,000 to ฿20,000+ a year depending on that choice, and keep your Thai driving license current before you ever need to use any of it. The class number matters less than the license in your wallet.
