Vietnam Traffic Rules for Tourists: A Phu Quoc Riding Guide
By Alex Nguyen · Updated September 2026 · 6 min read
Understanding Vietnam traffic rules is the first step every tourist should take before jumping on a scooter in Phu Quoc. The island's roads are relaxed compared to Hanoi or Ho Chi Minh City, but Vietnamese law still applies, and riding confidently means knowing what is expected of you — from the documents in your pocket to the way you merge into traffic.
Licence and IDP: What the Traffic Rules Actually Require
Vietnam requires riders to hold a valid driving licence appropriate to the engine size of the vehicle. For scooters up to 50cc no separate motorcycle licence is needed in many home countries, but for the larger automatics — the Honda PCX, Airblade, or SH Mode popular on Phu Quoc — you typically need a motorcycle endorsement on your licence.
An International Driving Permit (IDP) issued in your home country, when carried alongside your original national licence, is the standard way foreign riders demonstrate authorisation to Vietnamese authorities. The IDP alone is not enough; both documents together are what an officer may ask to see.
Licence categories and IDP rules can change, and enforcement varies. Always verify the current requirements with your home licensing authority and the Vietnamese embassy or consulate before you travel. Riding without a recognised licence is not just a traffic matter — it can affect your travel insurance cover.
Helmets: Non-Negotiable Under Vietnamese Traffic Rules
Helmet use is mandatory for all riders and passengers on every road in Vietnam. This is one traffic rule that is actively enforced across the country, including on Phu Quoc.
The law specifies helmets that meet Vietnamese safety standards. Cheap foam-shell souvenirs sold at markets do not qualify. At GoBike, every rental comes with a proper full-face or open-face helmet — we encourage you to wear it correctly, with the chin strap fastened, every single ride.
Children are also required to wear helmets. If you are carrying a child as a passenger, make sure a child-sized helmet is available before you set off.
Road Layout and Traffic Flow Rules on Phu Quoc
Vietnam drives on the right. If you come from a left-hand-traffic country, this is the single most important adjustment to make. Take a few minutes on a quiet side street to get used to the flow before joining busier roads.
Traffic signals, lane markings, and road signs follow broadly international conventions. Turning right at a red light is not automatically permitted — treat it the same as a full red unless a supplementary sign says otherwise. At roundabouts, vehicles already in the roundabout have priority.
On the island's main north–south road traffic moves relatively quickly. Stay in the right-hand lane unless overtaking, check mirrors before changing lanes, and never overtake on a blind bend or hill crest. On narrow plantation tracks in the interior, slow down and sound the horn briefly on blind corners — locals do this routinely and it is considered courteous rather than aggressive.
Speed Limits and How Traffic Rules Apply to Scooters
Speed limits in Vietnam are set by road type. Built-up areas and residential streets carry lower limits; the main island highway permits higher speeds. Phu Quoc's rural and coastal roads sit somewhere in between. Regardless of the posted limit, ride at a speed that gives you time to react to animals, children, or slow vehicles pulling out unexpectedly — these are everyday realities on island roads.
Exceeding the speed limit is subject to a fine issued by police, and fines are recorded and paid on the spot. The amounts are set by Vietnamese law and are updated periodically; we do not publish specific figures here because they change. Verify current fine schedules with official Vietnamese government sources.
Scooters are not permitted on certain national highways and expressways in Vietnam. On Phu Quoc this is rarely an issue as there is no urban expressway, but it is worth being aware of for the mainland.
Alcohol, Drugs, and Zero-Tolerance Rules
Vietnam enforces a zero blood-alcohol limit for motorcycle riders. Not reduced — zero. This has been in force since 2020 and is taken seriously. Even a beer with lunch puts you outside the law if you ride afterwards.
Roadside breath checks do occur on Phu Quoc, especially around popular tourist beach bars and during public holidays. If you plan to enjoy the island's nightlife, leave the bike at your accommodation and use a local taxi, Grab ride-hailing, or electric buggy instead.
Drugs of any kind are illegal in Vietnam and carry severe penalties. This is not a traffic rule — it is criminal law — but it bears repeating for visitors unfamiliar with the region.
Police Checks and Riding Etiquette for Tourists
Police checkpoints do appear on Phu Quoc, particularly on the main north–south road and near key junctions. If you are flagged down, pull over safely, switch off the engine, remove your helmet, and stay calm. Officers will typically ask to see your licence and IDP. Cooperating politely and without argument is both the right approach and the most practical one.
If a fine is issued, follow the officer's instructions and request an official receipt. If you feel the amount is unjust, note the details and seek advice after the stop rather than disputing it in the moment.
Riding etiquette matters too: use your horn sparingly (it signals presence, not anger), avoid blocking driveways when parking, and do not ride on the pavement. When reviewing our safety tips, you will find that most accidents on the island involve not licences but simple inattention — so staying focused on the road is your best protection.

Documents, Insurance, and What to Carry Every Ride
Every time you ride, carry your original national driving licence, your IDP, your passport (or a clear copy), and the bike's registration document. GoBike provides the registration papers with every rental bike. Keep these in a waterproof pouch — tropical downpours arrive without notice.
Third-party liability insurance is compulsory for all motorbikes in Vietnam. The bike's own insurance — a basic statutory policy — covers third-party claims, but it does not cover your medical costs or the bike if you are at fault. A separate travel insurance policy that explicitly covers motorbike riding with a valid licence is strongly recommended. Read your policy before you ride and confirm coverage with your insurer.
If you are unsure about any aspect of the legal requirements, speak to your hotel, a reputable rental shop, or the official Vietnamese Road Administration before getting on the road. GoBike's team is always available on WhatsApp at +84 94 852 31 39 to answer questions about the rental side of things. Book your bike with confidence once you have your documents sorted.
Frequently asked questions
Do tourists need an IDP to ride a motorbike in Vietnam?

The IDP alone is not sufficient — you need both. Verify the current requirements with your home licensing authority before travelling, as rules can change.
Is a car driving licence enough to ride a scooter in Phu Quoc?
It depends on the scooter's engine size and your home country's licence categories. For scooters above 50cc you generally need a motorcycle licence endorsement. Check with your local licensing body and confirm with your travel insurer, as riding on an incorrect licence can void coverage.

Vietnam applies a zero blood-alcohol limit for motorbike riders — no alcohol at all is permitted before riding. This rule is enforced with roadside breath checks, especially during holidays and near tourist areas.
Are helmets compulsory for passengers on Phu Quoc?
Yes, all passengers — including children — must wear a helmet that meets Vietnamese safety standards. Wearing a helmet is mandatory on every road in Vietnam, not just main highways.
What happens at a police checkpoint on Phu Quoc?
