Buying a used motorbike in Chiang Mai means completing a registration transfer at the Chiang Mai Department of Land Transport (DLT) in Nong Hoi. This process transfers the vehicle's registration from the seller to your name and is the step that makes you the legal owner in the Thai government's records. It takes between one and two hours if your documents are in order and a full day if they are not.
This guide explains the process step by step, what documents you need from both buyer and seller, what happens at the DLT on the day, and the practical reality of doing this as a foreigner in Chiang Mai.
Why the Transfer Matters
In Thailand, the vehicle registration document (the blue book, or สมุดคู่มือจดทะเบียนรถ) is the definitive record of who owns a vehicle. If you buy a motorbike and do not transfer the registration, you are not the legal owner in the government's system. The previous owner remains legally responsible for the vehicle including any fines, accidents, or tax obligations. For you, riding a bike not registered in your name creates complications with insurance, police stops, and any future resale.
Documents You Need
Gather everything before going to the DLT. Missing a single document means returning another day.
From the Seller
- Blue book (สมุดคู่มือจดทะเบียนรถ): the vehicle registration booklet
- Tax renewal book (สมุดบันทึกประวัติรถ): the annual tax and inspection record
- Seller's ID card (Thai national ID) or passport copy if foreign seller
- Signed transfer agreement (the DLT has a standard form or you can use a written agreement)
From the Buyer
- Passport (original)
- Proof of address in Chiang Mai (accommodation contract, utility bill, or TM30 notification)
- Valid vehicle insurance for the bike (Por Ror Bor at minimum)
The Transfer Process at the DLT
The Chiang Mai DLT is located in the Nong Hoi area on the south side of the city. Go during weekday business hours. The office opens at 8:30am and the queue builds up by mid-morning. Going early is better.
On arrival, the bike must be physically present for inspection. Staff check the engine and chassis numbers against the blue book. Do not leave the bike in the car park. Bring it to the inspection bay when directed.
After inspection, you queue for the transfer paperwork desk. The clerk processes the documents, collects the transfer fee, and issues a new blue book and tax book with your name as the registered owner. This part takes between 30 and 90 minutes depending on the queue.
Foreigner-Specific Notes
Foreigners can register motorbikes in Thailand in their own name with a valid passport. Some DLT officers are more experienced with foreign buyer transfers than others. If your Thai is limited, bringing a Thai-speaking friend or the bike seller who speaks Thai significantly smooths the process.
Your address on the registration will typically be the address you provide on your proof of residence. If you are at a hotel or guesthouse, the DLT may require more documentation. A rental contract or TM30 notification for a longer-term address is the cleanest option.
Insurance Before the Transfer
You need valid insurance on the bike before the DLT will process the transfer. The compulsory Por Ror Bor (third-party injury insurance) must be current. If the seller's insurance has lapsed, purchase a new Por Ror Bor policy before your DLT appointment. These are available at insurance kiosks near the DLT entrance and cost around 300 to 400 THB annually for a standard scooter.
Annual Tax Renewal After Transfer
Once the bike is in your name, annual tax renewal (which also serves as registration renewal) falls to you. The annual cost depends on the engine size and vehicle age. For a 125cc scooter it is typically 100 to 300 THB per year. Renewal can be done at the DLT, at designated post offices around the city, or through selected motorcycle shops with renewal authorisation.

Frequently Asked Questions
Can a foreigner register a motorbike in their name in Thailand?
Yes. Foreigners can register a vehicle in their own name at the DLT using their passport as identification. You will need a Thai address for the registration records. A rental contract or TM30 proof of address is the standard documentation used for this.
What is the blue book in Thailand?
The blue book (สมุดคู่มือจดทะเบียนรถ) is Thailand's vehicle registration booklet. It records the vehicle's registration history, owner details, engine and chassis numbers, and annual tax and inspection status. It is the primary document you need for any ownership transfer or registration renewal.
How much does a motorcycle registration transfer cost?
Transfer fees at the DLT are relatively small, typically 200 to 500 THB for a standard scooter. The exact amount depends on the vehicle's registered value and engine size. Budget around 500 THB to cover all DLT fees comfortably.
What happens if I ride a bike without transferring the registration?
You are riding a vehicle not registered in your name. The previous owner remains the legal registered owner. Insurance claims can become complicated. In any police interaction, the registration name not matching the rider can create procedural issues. It also means you cannot legally resell the bike without first completing the transfer.
Do I need to bring the seller to the DLT?
Not necessarily, but having the seller present simplifies any questions the clerk might have about the transfer documents. If the seller is not present, their signed documents and ID copies must be complete and correct. Missing information from the seller's side is the most common reason a transfer is delayed to a second visit.
Guru Tip
When buying a used bike, meet at the DLT rather than completing a private transaction first. Both parties go together to the DLT, the transfer is processed on the spot, and you leave with the bike legally in your name the same day. This eliminates any risk of the seller backing out after receiving money, guarantees the documents are in order before money changes hands, and means you have zero waiting period between purchase and legal ownership. It takes slightly more coordination but it is the cleanest way to buy a used bike in Thailand.
