A puncture can feel like an inconvenience until you are stopped on a fast road, in the dark or with children in the car. This guide to roadside tyre safety while waiting is about one thing: keeping people out of harm’s way while professional help is on its way. The tyre can be replaced. Your safety cannot.
Make the vehicle safe before you make a call
If the tyre has gone down while driving, resist the urge to brake sharply or steer suddenly. Ease off the accelerator, keep a firm grip on the wheel and slow down gradually. A flat tyre affects handling, particularly on a bend or in wet weather, so give yourself as much space as possible to pull over safely.
Choose a location where other drivers can see you early. A lay-by, car park, quiet side road or wide verge is usually far safer than stopping just beyond a bend, at the bottom of a hill or close to a junction. If you can safely travel a short distance at low speed to reach a safer place, that may be the better option. However, do not continue driving on a completely flat tyre or damaged wheel. Doing so can destroy the tyre, damage the rim and make control of the vehicle more difficult.
Once stopped, apply the handbrake, select first gear or Park, switch on the hazard warning lights and turn on sidelights if visibility is poor. If it is safe to do so, position the wheels towards the kerb. Keep the engine off unless you need it briefly for lighting, heating or demisting, and make sure the exhaust is clear if the engine is running.
Put people first, not the tyre
Your next decision depends on where you have stopped. On a quiet residential road with a safe pavement, it may be sensible for passengers to leave the vehicle through the kerb-side doors and wait well away from traffic. On a narrow country lane, stepping out may be riskier than remaining inside with seatbelts fastened. Look at the road, traffic speed, weather and the safe space available before moving anyone.
Children, elderly passengers and pets need particular care. Do not allow children to stand near the carriageway, search through the boot or wander off while you deal with the problem. Keep pets secured. A nervous dog near passing traffic can create another emergency in seconds.
If you have a high-visibility jacket, put it on before leaving the car, but only if you can do so without exposing yourself to traffic. A torch is useful at night, yet avoid standing in the road to signal drivers. Your hazards and vehicle lights are there to make the vehicle more visible. Your job is to stay safe.
Motorway and dual carriageway tyre safety
A tyre failure on a motorway or fast dual carriageway needs a different response. Never try to change a wheel on the motorway. Even a quick-looking job puts you dangerously close to high-speed traffic.
If the vehicle is still mobile, leave at the next exit or pull into a service area where possible. If you cannot do that, aim for an emergency area, lay-by or hard shoulder. Stop as far left as you can, with the wheels turned left. Switch on hazards, leave the vehicle by the left-hand door if it is safe, and wait behind a safety barrier and well away from moving traffic. Do not stand directly behind your vehicle.
On a smart motorway, use an emergency area wherever possible. If you are stranded in a live lane and cannot get to a place of safety, keep your hazard lights on and call 999 straight away. Tell the operator your location, direction of travel and any nearby marker signs. If you feel it is unsafe to leave the vehicle, remain belted in and follow the emergency operator’s instructions.
Do not put out a warning triangle on a motorway or dual carriageway. Walking back along the road is an unnecessary risk. On other roads, a warning triangle can help in suitable conditions, but only place one if you can do it without entering danger. It should be positioned well back from the vehicle, never around a blind bend or where it cannot be seen in time.
Give the tyre technician the right information
A clear call can reduce delays. Explain whether the tyre is punctured, blown out, split at the sidewall or simply losing pressure. Mention any visible damage to the wheel, whether the vehicle is loaded, and whether you have locking wheel nuts but cannot find the key. These details help the technician arrive with the right tyre options and equipment.
Your precise location matters just as much. A postcode is useful in a car park or residential street, but it may not be enough on a rural road. Give the road name, closest village, direction of travel, nearby landmark or mileage marker. If you are near Gatwick, for example, say which terminal approach road or access route you are on rather than simply saying ‘the airport’.
Also tell the technician if you are in an unsafe position. A mobile tyre service may be able to attend, but the repair or replacement must only be carried out where there is enough room to work safely. Sometimes the right answer is to move the vehicle to a safer nearby spot first, or arrange recovery when the location makes roadside fitting unsafe.
Avoid the mistakes that make a bad situation worse
It is tempting to keep driving because the tyre is only ‘a bit low’. That can turn a repairable puncture into a ruined tyre and buckled alloy wheel. If the steering feels heavy, the vehicle pulls to one side, or you hear repeated flapping or knocking, stop as soon as it is safe.
Do not rely on tyre sealant as a universal fix. Some punctures can be temporarily sealed, but sidewall damage, a large split, a tyre that has been driven flat or a damaged valve may need replacement. Sealant can also affect later repair options. If you use it, tell the attending technician.
Avoid attempting a roadside wheel change if traffic is close, the ground is soft or sloping, visibility is poor, or you are not confident with the equipment. A jack can sink, slip or become unstable. Locking wheel nut removal is also not a job for improvised tools. Damaging the wheel or snapping a stud can leave the vehicle in a more difficult position than before.
Finally, do not accept help from a stranger if their behaviour makes you uneasy. Keep doors locked where appropriate, speak through a slightly open window, and contact the service you have booked to confirm who is attending. A legitimate mobile technician should be able to identify the job and explain what they are there to do.
Stay ready while help is on the way
Once you have called for assistance, keep your mobile phone charged and your ringer on. If battery power is low, send your location and key vehicle details before making other calls. Check on passengers, keep warm and keep clear of the traffic side of the vehicle.
If conditions change – traffic builds up, visibility worsens, or you feel exposed – update the service provider. A good roadside response depends on accurate information, not guesswork. Emergency Tyres 24/7 LTD can bring the tyre shop to your roadside location across Surrey and Sussex, with a stated 45-minute response where conditions allow, but safety at the scene always comes first.
A puncture does not have to become a dangerous roadside incident. Make the safest decision you can, stay visible without putting yourself in traffic, and let a trained tyre specialist deal with the wheel when it is safe to do so.
