Your first priority is getting out of the traffic flow, not fixing the car
When a car breaks down, the instinctive response is often to think about the mechanical problem first, what’s wrong, can I fix it, how long will this take. But the actual first priority, before any of that, is getting yourself and the vehicle into a position of safety. Cars, and the people in them, get hurt at the roadside not because of the original mechanical fault but because of what happens afterward if the situation isn’t managed safely.
This matters everywhere, but particularly on faster roads and motorways, where a stationary vehicle and people standing near it are at real risk from passing traffic, especially in poor visibility, bad weather, or at night. Knowing the right sequence of actions before you’re ever in this situation makes a genuine difference to how safely it plays out if and when it happens to you.
This guide walks through what to do if you break down, both on ordinary roads and specifically on motorways where the risks and correct procedure differ, and what to do while you wait for help to arrive.
Getting the car to a safer position
If you feel a problem developing, a warning light, an unusual noise, a loss of power, try to move to a safer location before the car actually stops if you can do so safely, rather than waiting until you’re forced to stop wherever you happen to be. A layby, a wide verge, or simply pulling as far to the left as possible on a quieter road all reduce your exposure to passing traffic compared with stopping in a live lane or close to it.
Use your indicators to signal your intention clearly to other road users as you move over, giving them time to react rather than being surprised by a slowing or stopping vehicle. Once stopped, turn your wheels away from the road if you’re on a slope or verge, so that if the car does move for any reason, it moves away from traffic rather than into it.
If you genuinely can’t move the car at all, engine’s completely died, steering’s locked, stay in the vehicle with your seatbelt on if you’re in a live traffic lane and moving isn’t safely possible, and call for help immediately rather than attempting to push the car or fix anything yourself in a dangerous position.
Motorway breakdowns: a different level of risk
Motorway breakdowns carry significantly higher risk than breaking down on an ordinary road, given the speed of surrounding traffic and the reduced margin for error. If you can reach the hard shoulder, do so, indicating clearly and moving over as soon as it’s safe. Stop as far to the left as possible, ideally with the front wheels turned away from the traffic lanes toward the verge.
Exit the vehicle from the passenger side wherever possible, since this keeps you away from the traffic lane, and get behind the safety barrier if there is one, standing well back from both the hard shoulder and the live lanes. Never stand between your car and the traffic, and never attempt any repair yourself on the hard shoulder, this is genuinely one of the more dangerous places to be on the entire road network, and even fully stationary vehicles have been struck by other traffic misjudging the hard shoulder’s edge.
If your breakdown happens on a smart motorway without a hard shoulder, or in a section where the hard shoulder is used as a running lane, the guidance is different again: try to reach a designated emergency refuge area if at all possible, and if you can’t reach one and are stuck in a live lane, put your hazard lights on, keep your seatbelt on, and call 999 immediately rather than attempting to exit the vehicle in a live lane, which is far more dangerous than remaining inside with hazards on.
Warning other traffic you’re there
Once safely stopped, put your hazard warning lights on immediately, this is one of the simplest and most effective ways to alert approaching traffic that your vehicle isn’t moving as expected. If it’s dark or visibility is poor, also switch on your sidelights, since a stationary vehicle with only hazards flashing can still be harder to spot in certain conditions than one that’s also showing its regular lights.
A warning triangle, if you carry one and it’s safe to place, can add extra warning distance on an ordinary road, positioned a reasonable distance behind your vehicle to give approaching traffic time to react. Never place a warning triangle on a motorway, this specifically requires walking into the live carriageway or hard shoulder in a way that’s far more dangerous than the marginal extra warning it provides, and it’s not recommended by UK road safety guidance for this reason.
A high-visibility vest, kept in the car and put on before exiting the vehicle, makes you considerably more visible to approaching traffic in low light or poor weather, and is genuinely worth having ready in the car at all times, not just for breakdowns but for any roadside situation.
Staying safe while you wait for help
Once you’re in a safe position, resist the urge to get back in the car if it’s stopped on a motorway hard shoulder, current UK guidance is to wait outside the vehicle, behind a barrier if one is present, rather than inside it, given the risk of another vehicle colliding with yours while you’re waiting. On an ordinary road where you’ve been able to pull well clear of traffic, it may be safer to wait inside the vehicle depending on the specific situation, weather, visibility, and how far from traffic you actually are.
Keep children and pets inside a properly parked vehicle where it’s genuinely safer to do so, rather than having them stand at the roadside, and never let anyone attempt to cross a motorway carriageway or central reservation for any reason while waiting for help, regardless of how tempting a nearby service station or emergency phone on the opposite side might seem.
If you’re uncertain whether your specific situation is safer waiting inside or outside the vehicle, err toward getting as far from moving traffic as reasonably possible, since distance from the traffic flow is generally the biggest single factor in reducing risk while you wait.
Calling for help effectively
Once you’re in a safe position, call your breakdown provider or, on a motorway, use the free emergency roadside phones (marked posts pointing toward the nearest phone) or dial 999 if you don’t have a working mobile phone or the situation feels genuinely dangerous. Roadside phones connect directly to the National Highways control centre and can pinpoint your location precisely, which is genuinely useful if you’re not entirely sure of your exact position.
If you’re calling your own breakdown provider by mobile, be ready to give a clear description of your location, motorway name and junction numbers if applicable, or a specific description of the road and any nearby landmarks on an ordinary road. Modern breakdown apps and services can often use your phone’s location automatically, which speeds things up considerably compared with trying to describe your location verbally, particularly somewhere unfamiliar.
Give a brief, clear description of the fault if you know it, a warning light, unusual noise, or simply “won’t start,” since this helps the recovery service send appropriate assistance and gives them a rough sense of what to expect when they arrive.
What to keep in your car for breakdown situations
A hi-vis vest for each person who regularly travels in the car, kept somewhere easily reachable rather than buried in the boot under other items, is one of the simplest and most valuable additions to any car’s emergency kit. A torch, ideally one that doesn’t rely solely on a phone battery you might need for calling for help, is useful for breakdowns in poor light or after dark.
A basic first aid kit, a phone charger or power bank (so a flat phone battery doesn’t compound the situation), and a warm blanket, particularly useful if you’re waiting some time in cold weather, all add genuine value without taking up much space. If you’re prone to anxiety in unfamiliar situations, keeping your breakdown provider’s contact details saved somewhere accessible, rather than needing to search for them while stressed, is a small thing that helps considerably in the moment.
Building this kit once, and checking it periodically to make sure nothing’s gone missing or needs replacing, means you’re properly prepared rather than improvising in a genuinely stressful moment.
What not to do during a breakdown
Don’t attempt roadside repairs on a motorway hard shoulder, even something that feels simple, checking under the bonnet, changing a wheel, given how dangerous this specific location is regardless of how quick the task might seem. Don’t stand between your car and passing traffic at any point, and don’t attempt to push a stationary vehicle any distance on a motorway, this is far riskier than waiting for proper recovery.
Avoid unnecessary phone use beyond calling for help and updating anyone waiting for you, since staying alert to your surroundings matters more than being distracted by a screen while you’re in a roadside situation. And don’t assume other drivers will definitely see and avoid you, even with hazards on and a hi-vis vest, keep your distance from the traffic flow as a precaution rather than relying entirely on being seen.
Finally, don’t feel pressured to rush a decision about whether to attempt any DIY fix versus waiting for recovery. If you’re not certain the fault is something minor and safely fixable at the roadside, waiting for professional recovery is always the safer choice, even if it means a longer wait than you’d like.
Getting fast, reliable help across West Yorkshire
Knowing what to do if you break down matters, but having a reliable service to call matters just as much. SSK Mechanics offers recovery support across West Yorkshire and beyond, and we understand how stressful a roadside breakdown can feel, particularly if you’re unfamiliar with the area or travelling with children.
If your car breaks down and you need help fast, call SSK Mechanics recovery, and we’ll get to you as quickly and safely as possible, whether that’s a straightforward fix at the roadside or getting your vehicle recovered to somewhere it can be properly looked at. Staying safe while you wait matters most, but knowing help is genuinely on the way makes a stressful situation considerably more manageable.
Breaking down with children or vulnerable passengers
Breaking down is stressful enough alone, and it becomes more complicated when you have children, elderly relatives or anyone with reduced mobility travelling with you. Keep them calm and, on an ordinary road where it’s genuinely safer, inside the vehicle with seatbelts on rather than standing at the roadside. Explain simply what’s happening and what you’re doing about it, since a calm explanation tends to reduce anxiety more than trying to hide the situation entirely.
If you’re on a motorway and need everyone out of the vehicle and behind the barrier, move as a group rather than letting children wander, and keep a firm hold of younger children’s hands the entire time you’re near the hard shoulder. Pets should stay secured, either in a suitable carrier or on a lead well away from the traffic side of the vehicle, since a frightened animal near a live carriageway adds a genuine extra risk on top of everything else.
Having a plan for this scenario worked out in advance, rather than figuring it out under stress, makes a genuine difference to how smoothly everyone gets through what’s already an unwelcome interruption to the journey.
Talking through what to do in a breakdown before it actually happens, even briefly, means everyone in the car knows roughly what to expect and where to go if the worst does happen on a future journey.
It costs nothing but a couple of minutes of conversation, and it can make a genuinely stressful roadside situation much easier for everyone involved to handle calmly.
