What To Do If Someone Has a Heart Attack While Driving

Key Takeaway: If someone develops chest pain or other heart attack symptoms while driving, get them to pull over safely, stop the car, call 000, and keep them resting. Help them take prescribed angina medicine if they have it, and chew 300 mg aspirin if it is safe. If they collapse once the vehicle is safely stopped and they are not breathing normally, start CPR and use an AED.

A heart attack while driving is both a medical emergency and a road-safety emergency. The danger is not only the chest pain. It is the crash risk if the driver keeps moving, tries to make it home, or deteriorates before the car is fully stopped.

🚨 What To Do Immediately

1. Get them to pull over and stop the car safely

Healthdirect’s chest pain advice says chest pain should be considered heart-related until proven otherwise, and the Heart Foundation says a heart attack is a medical emergency. Do not let them keep driving to the next suburb, service station, or hospital if they can stop safely sooner.

2. Make the vehicle and roadside scene safe

Once the vehicle is stopped, put it in park, apply the handbrake, switch on hazard lights, and turn the engine off. If the car is in a risky position, do not create a second emergency by stepping into live traffic. Call 000 and follow the operator’s instructions about location and safety.

3. Treat it as a possible heart attack

The Heart Foundation lists warning signs such as chest pressure or pain, pain in the arm, shoulder, jaw, neck, or back, shortness of breath, dizziness, sweating, nausea, and unusual fatigue. Some drivers will describe it as indigestion, tightness, or just feeling suddenly very unwell.

4. Help with prescribed angina medicine if they already use it

If they have prescribed angina spray or tablets, help them take it exactly as directed while they rest. The Heart Foundation’s angina advice says to stop and rest first. Do not use someone else’s medicine and do not guess the dose.

5. Chew 300 mg aspirin if it is safe for them

Healthdirect says to call 000 if chest pain is severe, getting worse, or has lasted for 10 minutes. The Heart Foundation notes the operator may tell you what to do next, which can include aspirin. If the person is not allergic to aspirin and has not been told by a doctor not to take it, chew 300 mg aspirin.

6. Keep them resting and watch them closely

Keep them sitting upright or half sitting if that feels easiest for breathing. Loosen tight clothing, reassure them, and note when symptoms started. Do not give food or drink. If they become drowsy but keep breathing normally, be ready to place them in the recovery position once it is safe to manage them outside immediate traffic danger.

📞 Call 000 and Give a Clear Road Location

Healthdirect’s 000 guidance says if you are driving, tell the operator the direction you are going and the last motorway exit or town you passed. In a roadside emergency, location detail matters as much as the medical detail.

  • Say you think it may be a heart attack
  • Give the road name, travel direction, nearest exit, cross street, landmark, or kilometre marker
  • Say whether the person is conscious and breathing normally
  • Tell them whether the car is safely off the road or still in a risky location
  • Tell them when symptoms started and whether angina medicine or aspirin was given

If you do not know exactly where you are, use the Emergency+ app or the phone’s location tools if available. Stay on the line until the operator tells you to hang up.

🛣️ Why a Heart Attack While Driving Can Be More Dangerous

A heart attack while driving carries two risks at once: the heart emergency itself and the possibility of a crash. Even if the symptoms begin mildly, the person may suddenly become more distressed, dizzy, breathless, or unresponsive.

The NSW Ambulance emergency guidance is blunt about this: do not drive to hospital yourself in an urgent medical situation. That warning matters even more when the person already started the emergency behind the wheel.

People also lose time trying to make it home, to work, or to the nearest servo because they hope the pain will pass. Our guide to first aid for heart attack explains the general response, but the driving version adds vehicle control, roadside safety, and location handover for the ambulance.

⏱️ What To Do While Waiting for the Ambulance

Keep them resting

The safest position is usually sitting upright or half sitting, wherever breathing feels easiest. Do not let them resume driving, walk around on the roadside, or move more than necessary.

Keep the roadside safer

Leave hazard lights on. If another safe helper is present, they can stand well clear of traffic and direct emergency crews in. Do not cross active lanes or create extra risk just to wave people down.

Gather useful handover details

Have their medicine, allergies, known heart history, and symptom start time ready. If angina medicine or aspirin was given, note what was taken and when.

Do not leave them alone

A person with heart attack symptoms can suddenly deteriorate. Stay close enough to respond straight away if they stop answering, slump over, or lose consciousness.

💔 If They Collapse and Stop Breathing Normally

A heart attack can lead to cardiac arrest. Our guide to heart attack vs cardiac arrest explains the difference, but the practical rule is simple: if they are unresponsive and not breathing normally, start CPR as soon as the vehicle is safely stopped and the scene is safe enough to work in.

Call for help, follow the operator’s instructions, start chest compressions, and get an AED if one is nearby at a service station, shop, venue, or public building. If you need a refresher, our guides to CPR for adults and DRSABCD cover the basic sequence.

If they are unconscious but breathing normally, use the recovery position and keep checking breathing until the ambulance arrives.

❌ What Not To Do

Do not tell them to keep driving to see if it settles.

Do not drive them yourself to hospital if an ambulance is available.

Do not let them walk around on the roadside unless there is an immediate safety reason.

Do not give aspirin if they are allergic to it or have been told not to take it.

Do not leave them alone in the vehicle if symptoms are worsening.

🎓 Why First Aid Training Matters

A heart attack on the road becomes less chaotic when someone in the car already knows the order: stop the vehicle safely, call 000, rest the patient, give aspirin if safe, and move into CPR if they collapse. A HLTAID011 Provide First Aid course helps you practise chest pain emergencies, CPR, AED use, and clear emergency handover under pressure.

FAQs

Should I tell them to drive themselves to hospital?

No. If someone may be having a heart attack while driving, the safer move is to get the car stopped, call 000, and wait for the ambulance. Continuing to drive risks a crash and delays treatment.

What if it feels more like indigestion than chest pain?

Treat it seriously anyway. Heart attack symptoms are not always dramatic. If the person has chest pressure, tightness, pain spreading to the jaw, back, shoulder, or arm, shortness of breath, sweating, nausea, or sudden dizziness, get them to pull over and call 000 if symptoms are severe, getting worse, or last more than 10 minutes.

Can they take angina spray and keep driving if they feel a bit better?

No. If symptoms started while driving, they should stay stopped and be medically assessed. Help them take prescribed angina medicine if they already use it, but do not tell them to resume driving through a possible heart emergency.

What if they collapse before the car is fully stopped?

Getting the vehicle safely stopped is the first emergency. If you are a passenger, try to help them bring the vehicle to a safe stop without creating another crash, then call 000 and start CPR if they are unresponsive and not breathing normally.
