What to do if the police stop you on a bike in Vietnam

You’re riding through Nha Trang and a traffic police (CSGT) post waves you to stop. A tourist’s first reaction is panic. Relax: if everything is in order, it’s no big deal. Here’s a step-by-step so it goes smoothly.

First, the key thing

A 50cc bike needs no licence — it’s legal, and the police know it. They stop riders for a routine check: helmet, bike papers, sobriety. If all is fine, they simply let you go. For the amounts, see fines 2026.

Step by step: you’re stopped

1. Pull over calmly, switch off the engine, take off your helmet. Smile, be polite. Panic and arguing only hurt.
2. What they ask for: the bike papers (cà vẹt), sometimes passport/visa. They don’t ask for a licence on a 50cc — you don’t need one.
3. Hand over the papers. If all is clean, they check and let you go.
4. If you broke a rule (e.g. no helmet), they write a report (biên bản) and a fine. By law the fine is paid officially by receipt.
5. Language barrier: use your phone translator, stay calm, don’t argue loudly.

What NOT to do

• Don’t run — it only gets worse.
• Don’t be rude or argue aggressively.
• Don’t ride after drinking — the strictest violation.

What to always carry

To make a check a one-minute thing: a fastened helmet, the bike papers (cà vẹt, original or copy), a passport/copy, and never ride after drinking. With that, the police are just a formality.

Where we come in

Our bikes come with clean papers, checked against the police database — so no “no papers” or “wrong bike” trouble at a check. And they’re real 50cc — legal without a licence. You just show the cà vẹt and ride on.

Also useful: do you need a licence for a 50cc, where to buy and where not to. Ready to choose — catalog.
