How Long Is a 1968 IDP Valid in Vietnam?
We still get riders asking about the old “three-month rule”, because it has been repeated online for years and appeared in some of our older content too. We have checked it again and we do not find a current Vietnamese primary source that says every recognised IDP automatically expires three months after entry.
The rule we can verify is simpler: a recognised 1968 Convention IDP is valid for no more than three years from the date of issue, and never beyond the validity of the national driving licence behind it.
The IDP Has Two Clocks Running
The first date is printed on the IDP itself. The second is the expiry date of the national licence. If either one runs out, the document pair stops working.
That matters because the IDP is not an independent licence. It is only useful while the corresponding national licence remains valid and continues to contain the motorcycle entitlement you are relying on.
The Three-Month Rule Is Not a Blanket Rule
Residence, immigration status and licence exchange can create separate questions, but they should not be collapsed into an invented IDP expiry date. A foreigner who lives or works in Vietnam may have a Vietnamese licence-exchange route, yet that is not the same thing as saying the IDP document itself automatically dies after three months.
So when we check a customer’s documents now, we keep it simple: look at the IDP issue and expiry dates, check the home licence is still valid, and make sure the motorcycle category matches the bike. Residence or licence-exchange questions are separate and should not be mixed into the IDP expiry date.
Check the Permit Before You Plan Around It
Before booking a motorcycle, confirm that the permit is actually a 1968 Convention IDP. If it is a 1949 document or a private ‘international driving licence’, the expiry-date question may be beside the point because you could be looking at the wrong legal route altogether.
Then check the national licence. It must still be valid and it must cover motorcycles. A perfectly current IDP cannot keep an expired home licence alive or create a category that the home licence never had.
If you are unsure which permit you have
Use our International Driving Permit for Vietnam guide. It explains the convention wording, 1949 versus 1968 and the motorcycle-category check in one place.
What If Your Documents Expire During the Trip?
If the IDP or national licence is close to expiry, sort it before starting a long rental or tour. Short-term visitors should renew or replace the relevant document through the proper issuing route before relying on it in Vietnam.
Longer-term residents may have another option. A qualifying foreigner who is residing, working or studying in Vietnam can potentially exchange a valid national licence into the corresponding Vietnamese class, subject to the current documentation rules.
Keep the Rule Simple
The practical version is easy to remember: recognised 1968 IDP + corresponding valid national licence + correct motorcycle entitlement. The IDP can run for no more than three years and cannot outlive the home licence.

FAQ
Does a 1968 IDP automatically expire three months after I enter Vietnam?
We found no current Vietnamese primary legal source establishing a blanket rule that a recognised 1968 Convention IDP automatically expires three months after entry. Its validity can run for up to three years from issue, but never beyond the corresponding national driving licence. See our International Driving Permit for Vietnam guide for the wider document requirements.
Can the IDP stay valid after my national licence expires?
No. The IDP cannot outlive the corresponding national licence because the home licence is the underlying driving entitlement. If the national licence expires first, the IDP route ends at the same time even if the booklet itself shows a later date.
Can a three-year IDP let me ride any motorcycle for three years?
Do not treat residence and IDP validity as the same rule. Becoming a resident can make a Vietnamese licence-exchange route relevant, but that is a separate legal question rather than proof that the IDP automatically expires after three months. Qualifying residents should check the Vietnamese licence-conversion guide.
Does becoming a resident automatically cancel the IDP after three months?
Do not treat residence and IDP validity as the same rule. Becoming a resident can make a Vietnamese licence-exchange route relevant, but that is a separate legal question rather than proof that the IDP automatically expires after three months. Qualifying residents should check the Vietnamese licence-conversion guide.
What if my documents will expire during my trip?
Renew or replace the relevant document before depending on it for a long rental or tour. If either the IDP or national licence will expire during the trip, solve that before departure rather than hoping the date will never be checked.
Check Both Documents Before You Ride
A recognised 1968 Convention IDP can be valid for up to three years, but it cannot remain valid beyond the national driving licence that supports it. For motorcycle riders, that national licence must also include the appropriate motorcycle entitlement.
Before renting a bike in Vietnam, check the IDP, your national licence and your motorcycle category together. If you are unsure whether your documents allow you to ride legally, start with our How to Drive a Motorcycle Legally in Vietnam: 2026 Guide before choosing your motorcycle.
Once your documents are in order, you can explore our motorcycle rentals in Vietnam and choose a bike suitable for your licence, experience and route.
