Thai Department of Land Transport — Road Tax and Driving Licence Online
Everything drivers and vehicle owners deal with at the Department of Land Transport — and a clear line between what you can finish online and what still needs an office visit.

What you can do
-
Renew annual road tax online
Eligible vehicles can pay the annual tax through the online system without visiting an office, with the tax sticker posted out afterwards.
-
Driving licences, new and renewed
Covers every class of licence, from first-time applicants who must train and sit tests to holders whose licence is close to expiring.
-
Theory training you can do online
The training session required before testing or renewal can be completed through the department’s e-learning system and presented at the office.
-
Book ahead with DLT Smart Queue
For tasks that still require you in person, reserve a date and time in advance instead of queuing on arrival.
-
Registration and ownership transfer
Transfers after a sale, moving a registration between provinces and correcting registration details all start from the department’s own guidance and forms.
-
Start from the official channel
Road-tax pages are a favourite target for copycat sites, so opening the official address directly is safer than tapping a forwarded link.
What the Department of Land Transport handles
The Department of Land Transport (DLT) is responsible for two large areas that touch almost everyone who owns or drives a vehicle: the vehicle itself, and the driver. On the vehicle side that means registration, the annual road tax, transfers of ownership after a sale, and corrections to registration records. On the driver side it means every class of driving licence, from first-time applicants to holders approaching expiry. Over the past few years some of this work has moved fully online — the annual tax for eligible vehicles, and the theory training required of licence applicants and renewers — while much of the rest still needs you or the vehicle present, because a screen cannot stand in for an inspection or a driving test. The department’s website is the starting point for both: the tasks you can finish at home, and the appointment that gets you through an office door.
What you need before renewing road tax
Many people picture road tax as simply a payment, but it is really the last step in a chain of conditions. If one link is missing, the online system stops you — and a counter visit ends the same way. The amount is a second common misunderstanding: it is not the same for every vehicle but follows the vehicle’s class, its engine size or load capacity and its age, with statutory reductions for older vehicles in some categories. The real figure appears once you enter the vehicle’s details, so read it there rather than relying on a number someone passed along. What you need in hand before you start:
- Compulsory motor insurance (พ.ร.บ.) that is still in force on the day you pay.
- An inspection certificate from a licensed private centre (ตรอ.) once the vehicle reaches the age threshold set for its class.
- The details from the registration book — plate number, province of registration and vehicle particulars that match the database.
- A correct delivery address, since the sticker is posted to the address you enter rather than handed over at a counter.
Licences: a first one and a renewal are different journeys
A first-time applicant passes three gates in order. First the theory training for the required number of hours, which can now be taken through the department’s e-learning system from home. Then a written test on traffic law and safe driving. Finally a practical driving test on a testing ground. Both tests happen at a transport office, and you must bring identification along with the medical certificate the rules call for.
Renewing an existing licence is much shorter: the required training, which can also be done online, followed by a physical-ability check at the office covering things like eyesight and reaction time. The thing to watch is timing — start well before the expiry date, because letting a licence lapse for long enough can push you back into sitting the written and practical tests again. How long a lapse is tolerated, and how long each class of licence runs, differ by licence type, so confirm both on the official site.
Transferring registration when a used vehicle changes hands
A used-vehicle sale is not finished when the keys and the money change hands. Until the transfer is filed, the registration book still names the seller — awkward for both sides. The buyer cannot deal freely with the vehicle, and the seller stays attached to a vehicle they no longer hold. A transfer normally needs the original registration book, identification for both parties, a fully signed application form and, in many cases, the vehicle itself presented for inspection at a transport office.
What finishes online, and what needs an office
| Task | Can it be done online? | What to prepare |
|---|---|---|
| Annual road tax | Yes, for vehicles within the type and age conditions | Valid compulsory insurance, a ตรอ. certificate if the vehicle is old enough, and the registration details |
| Driving licence renewal | Training online; the physical-ability check is still in person | ID card, the existing licence and the supporting documents required |
| First driving licence | Training and booking online; both tests are in person | ID card, medical certificate and proof of training |
| Ownership transfer | Requires a transport office | The original registration book, identification for both parties and the signed application |
Why a page like this needs to exist
The department’s website blocks no search engine at all. The user’s problem is not access but retrieval: the information is spread across several sub-systems, and a great deal of it is published as documents. Someone typing “renew road tax online” or “how old before a vehicle needs inspecting” tends to land on an institutional front page — or worse, on a broker site that paid for the placement, which is precisely the gap the scam operators have been living in. So this page does one narrow job: explain what each task requires and where it can be done, in the words people actually search with, then hand you to the official address. ThaiGov.co is an independent directory. It is not part of the Department of Land Transport, it takes no tax payments, it does not act on anyone’s behalf and it collects no personal data — every transaction happens on the agency’s own systems.
How to use it
-
Decide which task you are doing
Annual road tax, driving licences and registration work are separate processes with separate paperwork. Some can be finished online; others need the vehicle or yourself present at an office. Sorting this out first saves a wasted trip.
-
Gather the prerequisites first
For road tax you need compulsory motor insurance (พ.ร.บ.) that is still in force, and — once a vehicle passes the age threshold set for its type — a certificate from a licensed private inspection centre (ตรอ.). Licence work generally needs your ID card and a medical certificate. Confirm the current requirements on the official site before you start.
-
Open the official site and register
Type the address yourself rather than tapping a link from an SMS or an ad, then register with your national ID number and an email address and phone number you actually use — the system verifies you and reports back through them.
-
Enter your details and pay
For road tax, enter the plate number, province and the details shown in the registration book; the system works out the amount due. Rates depend on the vehicle’s type, age and engine size, so read the figure the system shows before confirming.
-
Keep proof while the sticker is in the post
A payment record is issued immediately, with the tax sticker mailed to the address you gave. Print or save that record and keep it in the vehicle until the sticker arrives.
-
If you must attend in person, book a queue
Driving tests, ownership transfers and any case the online system will not accept require an office visit. Reserve a slot through DLT Smart Queue in advance and arrive a little ahead of your appointment.

Frequently asked questions
Can every vehicle renew its road tax online?
No. The online channel accepts only vehicles that fall inside the type and age conditions the department sets. Vehicles beyond those limits, with long-overdue tax, or with registration details that need correcting are usually rejected and must be handled at an office. The quickest check is to enter the plate number in the official system and let it tell you.
Do I need compulsory insurance before renewing road tax?
Yes. Valid compulsory motor insurance (พ.ร.บ.) is a precondition for paying the annual tax, and the system will not let you continue without it. Buy or renew the policy first, then come back. Note that compulsory insurance is not the same thing as voluntary motor insurance — holding a comprehensive policy does not remove the requirement.
Does my vehicle need a ตรอ. inspection first?
It depends on the vehicle’s type and age. Once a vehicle is older than the threshold set for its class, it must pass an inspection at a licensed private centre (ตรอ.) before the tax can be paid; newer vehicles are exempt. The thresholds differ between cars and motorcycles, so confirm the current rule on the official site before driving over.
I paid online but the tax sticker has not arrived — what now?
The sticker travels by post, so allow time for delivery. Keep the payment record the system issued in the vehicle meanwhile, and check the delivery status in the account you used. The usual cause of a long delay is a delivery address that no longer matches where you live. If it is well overdue, contact a transport office with your payment record.
Does renewing a licence mean training and an office visit?
Renewals normally require a training session, which can be completed through the department’s online e-learning system and then presented at the office. What still needs you in person is the physical-ability check and identity verification, so book a queue ahead. Supporting-document rules, such as the medical certificate, change from time to time — check before you travel.
How can I tell a road-tax site is genuine?
Judge by the domain: the genuine systems sit under dlt.go.th and nowhere else. Copycat sites use similar-looking names with a different ending and often buy ads that sit above the real result. Never enter ID or card details on a page you reached from an SMS or chat link — close it and type the official address yourself.
I bought a used vehicle but the seller has not transferred it — what should I do?
Until the transfer is filed, the registration still names the previous owner, and the obligations that follow the registration stay with that name. The fix is to go to a transport office together with the registration book, both parties’ ID cards and the signed application. The law sets a window for reporting a sale, so do not let it drift — check the current deadline on the official site.
