Vietnamese driving fines and police stops — the realistic guide
Blood-alcohol zero, helmet rules, speed limits, what fines are actually charged for foreigners, and what a typical police stop looks like.
Vietnamese traffic law in one paragraph
Vietnam's road traffic is governed primarily by the Road Traffic Law (most recently amended in 2024) and supplementary decrees that set specific fine bands. Enforcement sits with the traffic police (Cảnh sát giao thông, abbreviated CSGT), who can stop any vehicle at any time. Foreigners are subject to exactly the same rules as Vietnamese citizens — there is no tourist exception. The fines themselves are set in Vietnamese dong and published in official decrees; the figures below are estimates based on 2026 decree bands and should be treated as indicative, not precise. Always verify current rates, as decrees are revised periodically.
Blood-alcohol — the zero rule
Vietnam operates a strict zero-tolerance BAC policy for all vehicle operators. Any detectable blood-alcohol concentration is an offence. This is not a 0.05 limit or a 0.03 limit — it is zero. Roadside breathalyser checks are common, particularly after 10 pm in cities and around major holidays (Tết, National Day). The fines for a positive result are substantial — estimated at 6,000,000–8,000,000 VND for motorbikes and significantly higher for cars — and your licence can be suspended on the spot. Refusing a breathalyser test is treated as a positive result under current regulations. If you plan to ride or drive, do not drink. There is no safe amount.
Helmet and passenger limits
All motorbike riders and passengers must wear a helmet that meets Vietnamese standard QCVN 2:2008. Thin "fashion" helmets sold at roadside stalls technically do not meet this standard, though enforcement is inconsistent. The fine for not wearing a helmet is estimated at 400,000–600,000 VND per person (2026 estimate).
Passenger limits: most motorbikes are legally limited to one rider plus one adult passenger. Carrying a second adult passenger or more than one child beyond the legal definition is an offence. In practice, enforcement of passenger limits varies widely, but a checkpoint can and does issue fines for this.
Before you rent, read the motorbike rental guide — the helmet provided with your rental may not meet standard.
Speed limits by road type
Speed limits in Vietnam follow a tiered system. Estimates based on current regulations:
- Residential and urban streets: 40 km/h
- Urban roads with a central divider: 60 km/h
- Rural roads (no divider): 60–80 km/h depending on road class
- Highways (cao tốc): 90–120 km/h depending on the section
Speed cameras are present on highways and some national roads. Mobile speed traps (officers with radar guns) appear on routes where enforcement is prioritised. Fines for speeding are banded by how far over the limit you are travelling. For motorbikes, exceeding the limit by more than 20 km/h can result in fines estimated at 1,000,000–2,000,000 VND and licence suspension. These are estimates — verify before acting.
Common fines for foreigners
Most foreigners on motorbikes encounter fines for one of five things: no helmet, alcohol, running a red light, wrong-way riding on a one-way street, or not having the correct documentation. The last category is worth understanding: you need a valid driving licence that is recognised in Vietnam (see driving licence conversion for what that actually means), plus the vehicle registration documents (đăng ký xe), the vehicle's compulsory insurance (bảo hiểm), and your passport or residence card.
If you are riding a rented bike, the rental shop should provide the đăng ký xe. If they do not, or if it does not match the bike, you are carrying risk. Not having these documents can result in fines estimated at 200,000–400,000 VND and, in some cases, the bike being impounded until documents are produced.
What a typical police stop looks like
CSGT officers wear olive-green or grey uniforms and operate from marked vehicles or on foot at checkpoints. They signal you to pull over by pointing or using a wand. Pull to the left and stop the engine. Do not argue at the point of being signalled — just stop.
Most stops follow a pattern: the officer will ask for your licence, registration, and insurance. They may use a breathalyser. If there is no violation, you are waved on within a few minutes. If there is a violation, the officer will explain it — often in Vietnamese, sometimes with a phone translator or a bilingual colleague. Most cases at checkpoints are straightforward: a fine is issued, you pay at a designated post office or bank within a set period, and you are on your way.
In some cases officers may retain your documents until payment is made. This is a recognised enforcement mechanism, not necessarily corruption — though the two can overlap. Stay calm and polite throughout.
When to negotiate and when not to
Informal payments at the roadside exist. Whether you engage with them is a personal decision. What is worth knowing: at organised checkpoints with multiple officers and cameras present, informal payments are far less common than they once were — anti-corruption enforcement within the police has tightened. At a solo stop on a quiet road, the dynamic is different.
If a fine is legitimate and there is a formal process, going through the formal process — getting a receipt and paying at a bank or post office — is the cleaner outcome. If you pay informally and there is no receipt, there is no record that the stop happened.
For serious violations (positive BAC, accidents, suspended licence), do not attempt to negotiate informally. Contact your embassy or a local lawyer. This is not legal advice — consult a qualified professional for your specific situation.
Receipts and biên bản
A biên bản is a written record of the violation. You are entitled to one. If a fine is issued formally, you should receive a biên bản that details the offence, the fine amount, and the payment method. Read it as carefully as you can — if you do not read Vietnamese, photograph it and get it translated. The payment deadline is usually printed on the document. Missing the deadline increases the fine.
Keep your receipt (biên lai) after payment. If there is any subsequent query about the stop, the receipt is your evidence.
Where you don't have to argue
If you are stopped and the officer finds no violation, you can simply leave once they indicate you should. You do not have to accept a fine you do not understand. Asking for a biên bản or asking for the violation to be explained in writing slows the process and signals that you intend to engage with it formally — which is your right.
Being polite, keeping your documents in order, and not riding under any alcohol influence eliminates most of the risk. Road safety in Vietnam is a genuine concern beyond the question of fines — see the traffic safety guide for the wider picture.
Common pitfalls
- Carrying a photocopy of your passport instead of the original or a certified copy. Some officers accept this; others do not. Carry the original or a certified copy where possible.
- Riding without checking the bike's registration matches the bike. Always check the frame number against the đăng ký xe at the time of rental.
- Assuming a foreign licence works automatically. Most do not without conversion or an IDP — check the driving licence conversion page before you ride.
- Riding at night after eating at a restaurant that serves complimentary rice wine. The zero-BAC rule applies regardless of whether you sought the drink out.
- Not knowing your fine payment deadline. Missing it means a higher fine.
