Can You Be Sued for Performing First Aid?

The fear is understandable. You see someone collapse in a parking lot or slump over at a restaurant, and before your instinct to help fully fires, another thought arrives: what if I do something wrong? What if I hurt them and they, or their family, come after me legally? That concern keeps bystanders frozen at exactly the moment when moving would save a life. Research on bystander hesitation in cardiac arrest lists legal fear as one of the most common reasons people do not step forward.

Performing CPR or basic first aid during an emergency exposes a bystander to very little legal risk in the United States, and in most states almost none. That answer still needs context, because the fear is not only about probability. It is about not understanding the framework.

Why People Fear Helping

The fear of being sued for first aid has a few different roots. One is the general sense that the legal system can be unpredictable, even if you did everything right, someone could still file a lawsuit and drag you through an expensive process. Another is uncertainty about whether you are actually doing the technique correctly. A third is the specific worry about causing physical harm: CPR breaks ribs in many cases, and the person who called 911 and tried to help is now associated with that injury.

These concerns are not irrational, but they reflect a misunderstanding of how liability actually works in emergency situations. The legal system is not indifferent to the difference between a bystander who tried to save someone and a professional who made a preventable clinical error. Good Samaritan laws were specifically written to address this gap.

How Good Samaritan Laws Relate to First Aid

Every U.S. state has a Good Samaritan law. While the exact language varies, all of them share the same core principle: a person who voluntarily provides emergency care to someone in need, in good faith and without compensation, is protected from civil liability for the ordinary outcomes of that care. The protection exists precisely because state legislatures recognized that liability fear was causing people not to help, and people were dying.

Applied to CPR: if you see someone collapse, perform chest compressions, the person does not survive, and their family considers suing you, Good Samaritan laws are what shields you. The same applies if you break a rib during compressions, which happens frequently during effective CPR and is entirely expected. Courts understand this. Broken ribs from CPR do not constitute negligence; they are a known and accepted consequence of the technique. No case has successfully held a lay bystander liable for providing CPR in good faith in the United States.

The same principles apply to AED use. The federal Cardiac Arrest Survival Act and most state statutes explicitly protect lay responders who use an AED in a genuine cardiac emergency. Following the device’s voice prompts and applying the pads correctly is all that is required. The AED itself guides the responder; it will not deliver a shock unless it detects a rhythm that warrants one.

What Good Faith Means in an Emergency

The phrase “good faith” shows up in virtually every Good Samaritan statute. It is doing significant work, and it is worth understanding what it actually means in this context.

Good faith means you believed someone needed help and you acted to provide it. It means your motivation was to assist, not to cause harm or to act recklessly. It does not mean you did everything perfectly. It does not mean you have to be certified. It does not mean the person has to survive, or even that your intervention helped. The standard is intent and reasonable effort, evaluated against what a reasonable person with your level of training and knowledge would have done in the same situation.

A bystander with no formal training who calls 911, stays with the person, and performs hands-only CPR as best they can is acting in good faith. A certified first aid responder who follows their training is acting in good faith. Both are protected. The person who would not be protected is someone who acted recklessly or whose actions crossed the line into gross negligence, which is a dramatically different category from doing imperfect CPR under stress in a parking lot.

What Usually Falls Outside Protection

Good Samaritan laws do not provide unlimited protection, and it is worth being clear about what they do not cover. Gross negligence, conduct that is recklessly indifferent to the risk of harm, is excluded from protection in virtually every state. In practice, this standard is very difficult to meet for a bystander attempting CPR. The conduct would need to be so far outside reasonable bounds that it rises to something like intentional disregard for safety, not just performing a technique imperfectly.

Some states also limit protection to care provided by people who are not acting in a professional capacity. If you are an on-duty nurse or paramedic, you may be held to a different standard than a lay bystander, and your state’s Good Samaritan statute may treat you differently. Healthcare professionals should check the specific language in their state.

It is also worth noting that Good Samaritan laws govern civil liability, meaning lawsuits. They are not relevant to criminal law. For the vast majority of first aid and CPR scenarios, this distinction does not matter. For the kind of reckless conduct that falls outside Good Samaritan protection in the first place, it might.

Why Training Still Matters

None of the above is an argument against getting trained. If anything, training makes Good Samaritan protection more complete, more confident, and less theoretical.

When you are trained, “reasonable care” is easier to demonstrate because you know what reasonable care looks like. You know the correct compression rate, the proper hand placement, the ratio of compressions to breaths if you are providing rescue breaths. You have practiced on a manikin until it feels automatic. In an emergency, you are not guessing; you are executing a skill you have rehearsed.

Training also addresses the other piece of bystander hesitation that Good Samaritan laws cannot fix: the psychological barrier. Most people who freeze in emergencies are not afraid of being sued at that exact moment. They are afraid of doing it wrong, of making a decision they cannot take back. Certification removes the uncertainty. You know what to do. You have done it before, on a manikin, in a classroom, with an instructor watching. That practice turns a person who might help into a person who will help.
