Here is the sentence that surprises more Ha Giang travellers than any other: your International Driving Permit might be worthless in Vietnam — even if it is genuine, paid for, and shiny new. Not because of a scam, but because there are two different IDP treaties in the world, and Vietnam only recognises one of them. Whether you can legally ride the Ha Giang Loop comes down to which international driving permit your country issues — and that is decided by a treaty signed in Vienna back in 1968.
This guide explains the 1968 rule in plain language, lists the countries whose permits work in Vietnam (and the big ones that do not), and gives you a fully legal plan B if your passport is on the wrong list.

ToggleAn international driving permit is not a licence in itself — it is an official multilingual translation of your home driving licence, issued by your national automobile association (AA, AAA, ADAC and so on) before you travel. It only ever works together with your original licence, and it can only “translate” categories you actually hold. That last part matters enormously on the loop, as you will see below.
Two treaties govern IDPs worldwide:
Vietnam joined the 1968 convention and recognises only the 1968-format international driving permit. A 1949 IDP — however official it looks — has no legal force here. Police at a checkpoint will treat you as unlicensed, and your travel insurance can refuse a claim after an accident for exactly the same reason.

Here is the full member list — every country whose international driving permit Vietnam accepts under the 1968 convention (86 contracting parties; the always-current registry lives at the UN link above). Membership occasionally changes, so if your departure is months away, a 30-second check before you fly never hurts.
These countries put a signature on the 1968 convention decades ago but never completed ratification, so they still issue only 1949-format permits:
A valid 1968 international driving permit is only half the equation. Because an IDP merely translates your home licence, you also need a motorcycle category (A or A1) on the licence itself. A car-only licence plus a perfect IDP still does not let you ride a 150cc bike through the mountains — and the rental bikes on the loop are 110–150cc, above the 50cc threshold where licences become mandatory. French travellers know this pain well: a permis B alone is not enough, however valid the IDP.

Enforcement in Ha Giang has tightened noticeably in 2026, alongside the border-permit checks at Bac Sum, Yen Minh and the Dong Van gateway (details in our border permit guide). Riding unlicensed risks a fine of millions of dong, the bike being held — and the quiet catastrophe: a voided insurance policy at the exact moment you need it most. We have seen the paperwork question ruin more trips than the rain ever has. More on staying out of trouble in our guide to riding the loop safely.
If your international driving permit IS valid (and your licence has the A category), self-riding is a joy — see our motorbike rental guide for choosing the right bike.

Legally, no — and 2026 is the wrong year to gamble: checks are up, and insurance validity does not depend on whether you got caught, only on whether you were licensed.
From your national automobile association before you leave home (post offices in the UK). It cannot be issued after you arrive in Vietnam, and online “instant IDPs” are not legal documents.
No. Passengers need nothing but a helmet — provided — and a camera. That applies to every seat on our 2–5 day tours.
Not legally on the loop’s 110–150cc bikes. Join an Easy Rider or the car option instead.
Check three things before you book anything: your country is a 1968 party, your international driving permit says “1968”, and your home licence carries the A/A1 category. Three yes → rent and ride. Any no → ride with us instead: small groups (max 10), local Easy Riders, 2–5 day routes from $123, free cancellation up to 24 hours — and not a single form for you to worry about.
