Quick answer
First make the scene safe: switch on hazard lights, warn other traffic and do not put yourself at risk. Call 999 and give a clear location. Then follow DR ABC: check Danger, Response, Airway and Breathing. Do not move casualties unless they are in immediate danger.
A road crash can happen in seconds, and as a driver you may be the first person on the scene long before an ambulance arrives. Those first few minutes matter enormously, but helping well does not mean being a trained paramedic. It means staying calm, protecting yourself and others from further harm, calling for help quickly, and doing a few simple, safe things that can keep a casualty alive until the emergency services take over.
The theory test expects you to understand this basic sequence, and the reason is practical rather than academic. Panic and well-meaning but risky actions, such as dragging an injured person from a vehicle, can make things worse. A clear, ordered routine helps you think straight under pressure and avoid the most common and most dangerous mistakes.
The routine most first-aid courses in the UK teach is summed up as DR ABC: Danger, Response, Airway, Breathing. Around it sit a handful of rules about bleeding, shock, spinal injury and motorcycle helmets. This guide walks through each step in the order you would actually use it at the roadside.

What you'll be able to do
- Understand exactly what to do, and in what order, if you're first to arrive at a crash.
- Understand the simple, safe things you can do for an injured person until help arrives.
- Understand what to do if you break down — and the one place you must never use a warning triangle.
The facts that matter
- Make the scene safe first (Danger): switch on your hazard warning lights, warn approaching traffic, and never put yourself in harm's way to reach a casualty.
- Call 999 for the emergency services as soon as possible and give a clear, precise location so help can find you quickly.
- Follow DR ABC in order: Danger, Response (check whether they respond), Airway (gently tilt the head back to open it), Breathing (check they are breathing).
- Do not move a casualty unless they are in immediate danger, such as from fire, because of the risk of spinal injury.
- Do not remove a motorcyclist's helmet unless it is essential to keep the airway open.
- Stop serious bleeding with firm pressure on a clean pad, keep the casualty warm and calm to reduce shock, and give them nothing to eat or drink.

DR ABC in order
Danger, Response, Airway, Breathing. Think of it as a staircase you climb one step at a time: you only move on once the step below is dealt with. Danger always comes first, because you cannot help anyone if you become a casualty too.
Warm, calm, nothing to eat or drink
To reduce shock, keep a casualty warm and reassure them, but never offer food, water or a cigarette. If surgery is needed later, an empty stomach matters, and drinking can be dangerous if they are drifting in and out of consciousness.
Stay sharp
The mistakes everyone makes
Moving the casualty too soon
The instinct to pull someone out of a crashed car is strong, but unnecessary movement can turn a survivable spinal injury into permanent paralysis. Leave them where they are and support them there, unless there is an immediate threat to life such as fire, flood or explosion.
Removing a motorcyclist's helmet
Many people assume the helmet must come off to help. In fact you should leave it on. The only exception is if it is genuinely essential to keep the airway open, and even then it should be done with great care by supporting the head and neck.
Giving food or drink to be kind
Offering a shaken casualty a cup of tea feels caring, but it is a mistake. Anything in the stomach can cause problems if they need an operation, and swallowing is risky for anyone whose consciousness is fluctuating. Reassure them with words, not refreshments.
Out on the road
What this looks like in real life
A quiet A-road at dusk
You come across a car in a hedge with the driver slumped but the engine off and no smoke. Rather than rushing over, you first pull up safely, switch on your hazards and place yourself where you can wave down oncoming traffic. Only once it is safe do you approach and speak to the driver to check for a response. Because there is no fire, you leave her in the seat, keep her still and talking, and stay on the phone to 999 until the ambulance arrives. Not moving her protects a possible neck injury you cannot see.
A motorcyclist down at a junction
A rider has come off at a roundabout and is lying still with his helmet on. You resist the urge to pull the helmet off. Instead you check whether he responds and watch his chest to see if he is breathing, keeping his head and neck supported and as still as possible. He is breathing, so you leave the helmet in place, keep him warm with a coat, and wait with him. Leaving the helmet on avoided jolting his spine, and he was breathing freely anyway.
Quick answers
Frequently asked questions
What does DR ABC stand for?
DR ABC is the basic first-aid routine: Danger, Response, Airway, Breathing. First check for danger and make the scene safe, then check whether the casualty responds, ensure their airway is open by gently tilting the head back, and check that they are breathing. It gives you a calm, ordered plan under pressure.
Should I move an injured person out of the car?
No, not unless they are in immediate danger, for example from fire, flood or explosion. Moving a casualty risks worsening a spinal injury you cannot see. In almost all cases the safest thing is to leave them where they are, support and reassure them, and wait for the emergency services.
Do I take a motorcyclist's helmet off?
Generally no. Leave the helmet on, because removing it can move the head and neck and worsen a spinal injury. The only exception is if taking it off is essential to keep the airway open and the casualty breathing, and even then it should be done as carefully as possible while supporting the head.
How do I stop serious bleeding?
Apply firm, steady pressure directly over the wound using a clean pad or cloth. Keeping pressure on helps the blood to clot and slows the loss. If a pad soaks through, add another on top rather than removing it. Raising the injured part can also help, and keep the casualty warm to reduce shock.
