What to Do If You Break Down on a Motorway Hard Shoulder
A calm, step-by-step guide to breaking down safely on a motorway or smart motorway, based on National Highways guidance.
The three rules: get left, get out, get behind the barrier
A motorway breakdown is one of the most dangerous situations a driver can face, but the core advice from National Highways is simple and worth memorising before you ever need it. If you get into difficulty, the priorities in order are: get left, get out, and get behind the barrier.
Get your vehicle as far to the left as you safely can — onto the hard shoulder if the motorway has one, or into an emergency area if it does not. Get yourself and your passengers out of the vehicle through the left-hand (passenger) doors, so you are stepping away from traffic rather than into it. Then get behind the crash barrier and stand well back from the carriageway, ideally further up the verge from your vehicle so that you are not directly beside it if it is struck.
Reaching a safe place to stop
The moment you sense a problem — a warning light, a change in handling, a strange noise or a puncture — start planning to move left. Ease off the accelerator, signal, and work your way across to the hard shoulder or the next place of relative safety. On a traditional motorway that is the hard shoulder. On a smart motorway it may be an emergency refuge area (ERA), which is a marked lay-by, usually with an orange road surface and an SOS phone.
When you stop on a hard shoulder, pull as far to the left as possible, turn your wheels to the left, and leave your hazard warning lights on. At night or in poor visibility, keep your sidelights on too. Stop as far along the hard shoulder as you reasonably can if there is an obstruction, and try to stop near an emergency roadside telephone if you have the option.
Getting yourself and passengers to safety
Once stopped, do not linger in the car. Get everyone out through the left-hand doors and move behind the safety barrier, away from the carriageway and the sliproad. If you have a hi-vis jacket or vest, put it on — being seen is one of the biggest factors in staying safe. Keep together and keep well back from moving traffic.
There is one important exception: keep animals inside the vehicle. A frightened pet loose beside a live motorway is a serious hazard to it and to drivers. If you genuinely cannot get out safely — for example, you are in a live running lane and cannot reach a refuge — the guidance is different and covered below.
Do not attempt repairs on the hard shoulder
It is tempting to change a wheel or top up a fluid yourself, but the hard shoulder is one of the most dangerous places on the road network. National Highways is clear: do not attempt repairs yourself on the hard shoulder, and that includes changing a tyre. Vehicles pass within a metre or two at motorway speeds, and a moment kneeling by the offside is a moment too many.
The safe course is to get behind the barrier and call for help. A recovery operator will move your vehicle to a safe location before any work is done. If you have broken down with a puncture, this is exactly the situation where a mobile tyre fitter or recovery service should come to you rather than you attempting a roadside change in a live traffic environment.
How to call for help
From behind the barrier, you have a few options. The orange SOS emergency telephones spaced along the motorway connect you straight to National Highways, and crucially they tell the operator your exact location automatically — you do not need to know the marker post number. Marker posts along the verge also carry a number and an arrow pointing you to the nearest phone.
You can also call National Highways on 0800 023 7237 to report a breakdown or hazard. If you or anyone else is in danger — for example you cannot get out of the vehicle, or someone is injured — call 999 immediately. When you call, try to give the road number (for example M6), the direction of travel, and the nearest marker post or junction so help can reach you quickly.
Smart motorways and all-lane running
Many motorways have been converted to smart motorways, and the most significant change is all-lane running (ALR), where the former hard shoulder has been turned into a permanent running lane. On these stretches there is no continuous hard shoulder to pull onto, which changes your plan for a breakdown.
On an all-lane-running motorway, aim to reach the next emergency refuge area — the orange-surfaced lay-bys with an SOS phone, signed in advance and spaced along the route. If you can reach one, pull in fully, exit via the left, get behind the barrier and use the SOS phone. If a red X is shown above a lane on the overhead gantries, that lane is closed and you must not drive in it.
If you cannot reach a refuge area
Sometimes a vehicle fails suddenly and you cannot reach a hard shoulder or refuge. If you can move to the verge or nearside, do so, keep your hazard lights on, and if it is safe get out on the left and behind the barrier as before.
If you are stuck in a live running lane and cannot get to safety, keep your seatbelts and hazard lights on, stay in the vehicle, and call 999 straight away. National Highways can use the control room and cameras to close the lane and set the overhead signs to protect you. Do not attempt to get out into live traffic. This is a genuine emergency and the fastest, safest response is to let the control room close the lane around you.
When the immediate danger has passed
Once you are safe behind the barrier and help is on the way, stay calm and stay put. Do not go back to the vehicle for belongings unless it is genuinely safe. Keep an eye on approaching traffic and be ready to move further back if needed.
If your vehicle needs recovering rather than a quick fix, a recovery service can take you and your car to your home, a garage of your choice or a safe location. If you would like to arrange recovery from a motorway or any road, call 07737477003 and we can talk through your location and the safest next step.
