Stopping on a Bridge or Flyover With a Fault: Getting Clear of the Carriageway Safely
About 6 minutes to read
A motorbike breakdown on a bridge or flyover in Hanoi can leave a stalled bike in a running lane where the law restricts stopping and there may be little room to pull aside. Three official pages bear on it: Vietnam’s 2024 Law on Road Traffic Order and Safety on where stopping is banned and what a fault requires, the UK Highway Code’s breakdown rules on getting clear of moving traffic, and a Honda Vietnam owner’s manual on what to check after trouble on the road. Neither Hanoi’s individual bridges nor rental bikes appear in any of them, and the last sections deal with those blanks.
Where the 2024 law bans stopping
Vietnam’s Law on Road Traffic Order and Safety, No. 36/2024/QH15, has applied since 1 January 2025; its full text was posted on 9 September 2024 by the Nghe An Public Administration Service Centre. Article 18 separates stopping, a temporary standstill for as long as needed for tasks such as a technical check of the vehicle, from parking, a standstill with no time limit. It then lists places where neither is allowed. The ones that apply to a bridge or flyover stop are:
| Place | Article 18(4) rule |
|---|---|
| On a bridge | Not allowed unless the traffic organisation provides for it |
| Under a flyover | Not allowed except where stopping or parking is permitted |
| Curves or near a hill crest with a hidden view | Not allowed |
| Junctions | Not allowed at the junction or within 5 metres of its edge |
| Carriageway only wide enough for one lane of motor vehicles | Not allowed |
Article 15(4) adds that U-turns are not allowed on bridges, at bridge approaches or under flyovers, among other places, unless a traffic controller or a temporary sign directs otherwise. Neither list mentions a breakdown; clause 7 of Article 18, below, deals with that case.
When a fault forces the stop anyway
The law does provide for a fault that leaves no choice. Article 18(7) says that when a technical fault or other unavoidable event forces a vehicle to park on part of the carriageway or somewhere parking is not allowed, the driver must signal with hazard lights or place a warning sign behind the vehicle. Article 18(5) and (6) say where to stop when there is a choice: on a wide shoulder or land beside the carriageway, or, if the shoulder is narrow or missing, close to the right-hand edge; in town streets, tight to the right-hand kerb, with the closest wheel within 0.25 metres of it.
Article 26(2), written for road tunnels rather than bridges, goes into more detail. A vehicle forced to stop must move to an emergency stopping place; if it cannot move, the driver must use hazard lights, put a warning sign or light behind at a safe distance and quickly inform the traffic police or the tunnel’s management. Expressway rules in Article 25 do not apply here, because the same article bars motorcycles and mopeds from expressways.
Getting clear of moving traffic
For the human side of the stop, the breakdown rules in Britain’s Highway Code on GOV.UK give general guidance; they are British rules, not Vietnamese law. Rule 275 asks drivers to stop in a “place of relative safety” and says the safest place is one designed for parking. It says people should, where possible, keep well away from the vehicle and from moving traffic, because traffic could hit the vehicle and force it into them. Rule 276 adds:
- get the vehicle off the road if possible;
- use hazard warning lights if the vehicle is causing an obstruction;
- wear light-coloured or fluorescent clothing by day and reflective clothing at night;
- place a warning triangle at least 45 metres behind on the same side of the road, taking great care when placing or retrieving it, but never on motorways;
- do not stand between the vehicle and oncoming traffic.
Rule 277, written for motorways, says to get behind a safety barrier where there is one, while staying aware of unseen hazards such as sudden drops, and not to attempt repairs on the vehicle. On a bridge or flyover the far side of a barrier may itself be such a drop, so that part of the rule cannot simply be copied onto a span.

Moving the bike off the span
The pages say little about how a broken-down motorbike should be moved. Article 33 is the exception: it forbids a motorcycle rider to tow or push another vehicle with their own bike, and forbids passengers to cling to, pull or push other vehicles. A helper riding alongside and shoving the stalled bike forward with a foot would appear to fall under that wording. Honda Vietnam’s NSC110CBF manual adds that its engine cuts out if the side stand is lowered while running and will not start with the stand down, so a stand left down is one thing to check before deciding the bike has failed. Whether a rider should walk the bike off the bridge, wait beside it or call for a recovery vehicle is not covered.
Telling the shop exactly where the bike is
The Highway Code’s motorway section lists ways to give a location: a mobile phone mapping application, or the numbers and letters on marker posts at the road edge. Rule 283, for incidents, asks callers to give the emergency services full details of the location and any casualties. The same habits fit a call to a rental shop: a map pin, the name of the bridge or flyover, the direction of travel and which end of the span is nearer. If the fault is running out of fuel, Reading a Rental Bike Fuel Gauge: Plan Range Without Guessing covers planning range in advance.
If the stop follows a crash or a flat tyre
Honda Vietnam’s NSC110CBF manual says safety of life comes first when something goes wrong on the road. If anyone is injured, assess how serious it is and call for emergency help if needed, and follow local rules when other people or vehicles are involved. A rider who decides to carry on should first turn the ignition off and check the bike: leaks, the key nuts and bolts, handlebar, levers, brakes and wheels, then ride very slowly, because damage may not be visible. The manual recommends leaving puncture repairs to an authorised Honda store; for a small hole in a tubeless tyre it mentions an emergency repair with a tubeless-tyre repair kit, but says riding on a temporary repair is very dangerous and sets a limit of 50 km/h until the tyre is replaced. Puncture steps are covered in Rental Motorbike Puncture in Hanoi: Where to Stop and What to Record.
What the pages leave out
No page names a Hanoi bridge or flyover, says which ones motorbikes use or describes their shoulders and barriers. The pages give no Vietnamese emergency or traffic-police phone number, no recovery service and no response time. The law sets the general duty to signal a forced stop but gives no step-by-step rule for a motorcycle that dies mid-span, and it does not say whether pushing the bike on foot is expected. Rule 277 was drafted for British motorways and rules 275 and 276 for British roads in general; they are cited for their safety logic only. Recovery arrangements, costs and liability on a rental are not addressed anywhere.
