What you do in the first two minutes after a motorbike accident matters more than almost anything else you will do as a rider — for the person on the tarmac, and legally for yourself. The legal duties after an accident are set out in motorbike-accident-duties-vietnam; this is the practical first-response sequence.
1. Stop the scene from growing
Traffic keeps moving at accident scenes in Vietnam, and the first task is to make sure no second collision happens: hazard awareness behind, bikes waved around, the fallen bike moved out of the live lane if it can be done safely. Do not become the second casualty while helping the first.
2. Do not move the rider unless you must
The classic instinct is to lift the fallen rider. If they are conscious and can move, let them move themselves. If they are not — possible spine, neck or head injury — moving them without need can turn a recoverable injury into a permanent one. Move them only if the location itself is dangerous (fire risk, live traffic), and then with the head and spine kept in line.
3. Check, call, hold
Check responsiveness and breathing. Call the emergency number early — 115 is Vietnam’s medical emergency number, reachable nationwide. Keep the injured person warm and still; a foil blanket from first-aid-kit-motorbike-riders-vietnam is the exact tool. Control visible bleeding with direct pressure and gauze.
4. The legal frame
Stopping and helping at an accident you are involved in is a legal duty, and leaving the scene is a serious offence — motorbike-accident-duties-vietnam covers the verified rules and penalties, and stopped-by-traffic-police-vietnam covers the police interaction that follows. If you carry your own insurance, do-you-need-insurance-to-ride-vietnam explains why that call also matters tonight.
The one-line version
Make the scene safe, do not move a still casualty, call 115, stop and help — the law requires the stopping, and the first two minutes require the calm.
