1. Move Left and Stop Safely, Then Switch On Hazard Warning Lights
The first rule of a motorway breakdown is to get off the carriageway if you possibly can. Steer onto the hard shoulder, pull as far left as the road allows, and stop with your wheels turned slightly toward the verge so the vehicle is angled away from passing traffic.
Once stationary, switch on your hazard warning lights immediately. This is not optional at night. Hazard warning lights are the single most recognisable signal that your vehicle is a stationary hazard, and at dusk or in darkness they give approaching drivers their first warning that something is wrong ahead.
If you cannot reach the hard shoulder and your car comes to a halt in a live lane, leave the hazard lights on and treat the situation as an emergency. Do not attempt to push the vehicle or step into traffic.
Never open the driver’s door into a live lane. A common mistake is to step straight out into the path of passing vehicles. Always exit through the left-hand doors only.
2. Get Everyone Out Through the Left Doors and Behind the Barrier
Everyone leaves the vehicle through the left-hand doors and waits behind the barrier. That is the whole instruction, and it applies to every passenger, every time.
Move to a safe place well away from the carriageway, ideally up an embankment or behind the safety barrier, and stay there until help arrives. Leave animals in the vehicle unless the car is in immediate danger.
The Highway Code is clear that you should not place a warning triangle on a motorway carriageway. At night, walking into a live lane to set one down puts you directly in the path of traffic moving at speed, and it is one of the most dangerous things a stranded driver can do. The standard advice from National Highways on motorway breakdowns is to stay behind the barrier and let your hazard lights and any warning beacon do the signalling for you.
3. What to Do If You Break Down on a Smart Motorway
Breaking down on a smart motorway changes the playbook. If you can reach an emergency refuge area, use it. These bays sit off the carriageway and give you a protected space to stop, and they are marked by blue signs with an orange SOS symbol.
If you cannot reach a refuge area and your vehicle stops in a live lane, do not get out. Keep your seatbelt on, switch on your hazard warning lights, and call 999 immediately. Emergency services can close the lane and warn approaching traffic through the regional control centre.
If you do reach a refuge area, use the roadside telephone if one is provided. It connects directly to the control centre, which can set the overhead signs to alert other drivers.
4. Call 999 or Your Breakdown Provider and Give an Exact Location
Call 999 if you are in a live lane, if anyone is injured, or if you feel unsafe. Otherwise call your breakdown provider. Either way, the operator needs one thing above all: an exact location.
Marker posts along the hard shoulder carry a letter and a number that identify your position to within a short distance. The emergency refuge areas on smart motorways are numbered too. Read those details out, along with the carriageway direction and the nearest junction.
If you cannot identify a marker post, a location app that gives a precise three-word address can help. The What3Words app assigns a unique three-word address to any three-metre square, and emergency services use it to find stranded drivers quickly. Give the operator your location, your vehicle description, and whether you are alone or with passengers.
5. Use High Visibility Roadside Safety Equipment to Be Seen
High visibility roadside safety equipment is what turns an invisible stranded car into something approaching traffic can see and avoid. At night, your vehicle’s own lights and reflectors are often not enough, especially if you are parked on an unlit stretch of hard shoulder.
A reflective vest kept in the cabin, not buried in the boot, is the baseline. Wear it before you step out of the car. Beyond that, a portable LED warning beacon placed on the roof or beside the vehicle gives approaching drivers a bright, unmistakable signal that a stationary hazard is ahead.
Roadflash builds exactly this kind of equipment: multi-award-winning early warning systems designed for stationary vehicles on busy motorways. Their beacons use high-visibility lighting and, in the DGT 3.0 compliant models, GPS and geolocation that can help pinpoint your position. The point of all of it is simple. Increase hazard awareness, improve how visible your vehicle is at the side of the road, and reduce the risk of a high-speed collision.
6. Stay Alert, Stay Warm and Manage the Wait
Breakdowns rarely resolve in five minutes, and at night the wait can stretch on. What you do during that wait determines whether you stay safe or drift into risk.
Light discipline. Keep your hazard lights on for as long as the vehicle is a hazard. If you have a portable warning beacon, place it where approaching drivers will see it first, not where it blinds you. Use a torch for your own movement, but avoid shining it into the carriageway or at oncoming drivers, and avoid standing in its beam where you become a silhouette against the light. A red rear-facing light or reflector on the barrier side of your group helps the recovery driver find you without dazzling passing traffic.
Phone battery. Your phone is your lifeline, so treat the battery as a resource. Turn the screen brightness down, close background apps, and avoid streaming or scrolling. If you have a power bank, keep it in the cabin rather than the boot so you can reach it without opening the tailgate into traffic. If the battery is critically low, agree a check-in time with the operator and then switch the phone off between calls.
Precise location sharing. Marker posts along the hard shoulder carry a letter and a number that identify your position to within a short distance, and emergency refuge areas on smart motorways are numbered. Read those out. If you cannot find a marker post, a location app that gives a precise three-word address can help. The What3Words app assigns a unique three-word address to any three-metre square, and emergency services use it to find stranded drivers quickly. Share that address with the operator, and if you are using a breakdown provider app, share your live location so the patrol can track you.
Fatigue and cold. Both dull your judgement, which is the last thing you want beside a motorway. A blanket, a waterproof layer, and a charged phone make a long roadside wait far more bearable. If you are travelling with a breakdown provider, real-time tracking in their app can tell you when help is close. The RAC breakdown cover and similar services let you follow the patrol vehicle, so you know roughly how long you will be waiting and can plan accordingly. If you feel yourself getting drowsy, stand up, move gently behind the barrier, and keep talking to your passengers rather than sitting still and quiet.
Never wait in the vehicle on a live lane, and never stand between your car and oncoming traffic. The hard shoulder is not a safe place to sit, even with hazard lights on.
7. Look After Vulnerable Passengers and Keep Calm
Children, older passengers, disabled passengers, and pets all change the calculation during a night-time breakdown. The technical steps stay the same, but the order in which you do them, and how long each one takes, does not.
Children. Get them out through the left doors and behind the barrier before you do anything else that involves leaving the vehicle. A child who is cold, frightened, or wandering is a bigger risk than a car that is not perfectly positioned. Keep them within arm’s reach, give them a job if it helps (holding the torch, watching for the recovery vehicle), and keep the explanation short and factual. Children take their cue from the adult who is calmest, so slow your own voice down deliberately.
Older and disabled passengers. Ask before you assume. Someone who uses a walking aid, has a heart condition, or struggles with steps may find the barrier itself a hazard in the dark, especially on an embankment. If moving them is riskier than keeping them in the vehicle, and the vehicle is on the hard shoulder or in a refuge area rather than a live lane, keeping them belted in with the doors locked may be the safer call. Tell the operator when you call so the response can be prioritised.
Pets. Leave animals in the vehicle unless the car is in immediate danger. A dog loose on the verge at night is a danger to itself, to you, and to traffic. If you must move an animal, use a lead and keep it on the barrier side, away from the carriageway.
Panic. Panic is contagious, and so is calm. The single most useful thing you can do is narrate what is happening in plain terms: what you have done, who you have called, roughly how long help usually takes. Uncertainty is what feeds fear, so replace it with information. If someone is spiralling, give them a concrete task. Holding a torch, watching for the recovery vehicle, or reading out the marker post number all give the nervous system something to do other than imagine the worst.
If you are travelling with a vulnerable passenger, tell the breakdown operator when you call. They can prioritise the response and advise you on the safest place to wait, which matters more at night when visibility is poor.
At night, the group’s emotional state is a safety variable, not a side issue. A calm, informed, task-focused group stays behind the barrier and out of the carriageway. A panicking one does not.
Frequently Asked Questions
What should you do if you break down on a motorway at night?
Pull onto the hard shoulder or into an emergency refuge area, switch on your hazard warning lights and sidelights, and leave the vehicle through the left-hand doors. Wait behind the barrier if you can. Call 999 or your breakdown provider with your location. Never attempt repairs on the hard shoulder at night.
Is it safer to stay in the car during a motorway breakdown?
The Highway Code says you should leave your vehicle and wait behind the barrier if it is safe to do so. On a smart motorway with no hard shoulder, this is especially important because a live lane offers no protection. If you cannot exit safely, keep your seatbelt on and call 999 immediately.
What are the specific risks of breaking down on a smart motorway?
There is no permanent hard shoulder, so a stationary vehicle can be in a live lane. The risk of a high-speed rear-end collision is far greater than on a conventional motorway. If you cannot reach an emergency refuge area, you should move left as far as possible, switch on hazard warning lights and get out of the vehicle if safe.
How can I make my vehicle more visible to other drivers at night?
Switch on hazard warning lights and sidelights. If you carry high visibility roadside safety equipment, deploy a warning beacon behind the vehicle and wear a reflective vest. These aids increase hazard awareness and improve vehicle visibility at the side of the road, especially on unlit stretches.
Should I attempt to change a tyre on the hard shoulder at night?
No. Changing a tyre on the hard shoulder at night puts you inches from fast-moving traffic. Call your breakdown provider or 999 if you feel unsafe. A professional recovery service can move your vehicle to a safer place before any repair is attempted.
