A Good Samaritan law protects you from being sued for ordinary mistakes when you voluntarily help someone during an emergency. Every state and the District of Columbia has one, and the basic deal is the same everywhere: if you step in during a genuine emergency, act in good faith, and don’t charge for your help, you can’t be held civilly liable for honest errors made while trying to save someone. What the law will not do is protect reckless behavior, deliberate harm, or someone acting well outside the role of a volunteer rescuer.
What the Law Actually Protects
The protection is against civil liability for ordinary negligence. In practice, that means the person you helped (or their family) cannot successfully sue you because your rescue attempt was imperfect. If you perform chest compressions on someone in cardiac arrest and crack a rib, you’re covered. Broken ribs during CPR are common, and without this shield, every bystander who did compressions would be a lawsuit waiting to happen.1National Center for Biotechnology Information. Good Samaritan Laws
To qualify, four conditions generally need to line up:
- The situation is a true emergency involving real risk of serious injury or death.
- You acted voluntarily, without any professional or contractual duty to help.
- You did not charge for your assistance. Billing later strips the protection.
- You acted in good faith, meaning you were genuinely trying to help.
Most people acting on instinct meet these conditions without thinking about them. The law is deliberately forgiving on the front end because the whole point is to remove hesitation.
Where the Protection Ends
Good Samaritan immunity is not a blanket. It covers honest mistakes; it does not cover gross negligence, willful misconduct, or intentional harm.1National Center for Biotechnology Information. Good Samaritan Laws
The line between ordinary and gross negligence matters. Ordinary negligence is failing to do what a reasonable person would do in the same situation. Gross negligence is a conscious disregard for the safety of the person you’re trying to help. Splinting a broken arm badly is ordinary negligence and stays inside the protection. Deciding to attempt roadside surgery with a pocket knife is not.
The other way to lose the protection is to abandon the person. Once you start a rescue, you’ve taken on a duty of care. Walking away before qualified help arrives, without a good reason, can expose you to liability. The safest practice is simple: stay with the person until paramedics or other responders take over.
Consent From the Person You’re Helping
If the person is conscious and alert, ask before you help. A conscious adult can refuse aid, and continuing over their objection can cost you the protection.1National Center for Biotechnology Information. Good Samaritan Laws
When someone is unconscious or unresponsive, the law assumes they would consent to emergency care if they could. This is called implied consent. You can start CPR on an unconscious stranger without worrying you lacked permission. The narrow exception is when you know the person previously refused treatment, such as through a medical directive.
Do Doctors and Nurses Get the Same Protection?
It depends on whether they’re on the job. Healthcare professionals acting within their normal duties generally do not get Good Samaritan protection, because they already have a professional obligation to provide care.1National Center for Biotechnology Information. Good Samaritan Laws A physician on shift in an emergency department is doing their job, not volunteering. The same applies to any provider with a pre-existing duty to the patient through employment, an on-call agreement, or an existing provider-patient relationship.
Off duty is different. A cardiologist who stops at a highway crash and gives roadside first aid is acting as a volunteer, and Good Samaritan protection typically applies. Some states extend coverage even further, to off-duty physicians called into an emergency department they have no obligation to respond to. That piece varies by jurisdiction.
Federal Protections You Might Actually Use
Two federal laws layer on top of the state rules and reach situations most people never think about until they’re in one.
Using an AED
Automated external defibrillators are now mounted in airports, gyms, offices, and schools. Under 42 U.S.C. ยง 238q, anyone who uses or attempts to use an AED on someone in a perceived medical emergency is immune from civil liability for resulting harm. The person or organization that acquired and placed the device is also protected, as long as they maintained it properly, notified local emergency responders of its location, and trained employees reasonably expected to use it.2Office of the Law Revision Counsel. 42 USC 238q – Liability Regarding Emergency Use of Automated External Defibrillators
The usual carve-outs apply. Federal AED immunity does not cover willful misconduct, gross negligence, or reckless behavior, and it does not shield licensed healthcare professionals using an AED within the scope of their employment at a healthcare facility.2Office of the Law Revision Counsel. 42 USC 238q – Liability Regarding Emergency Use of Automated External Defibrillators
Volunteering With a Nonprofit
The Volunteer Protection Act of 1997 shields volunteers of nonprofit organizations and government entities from personal liability for harm caused while acting within the scope of their volunteer responsibilities. The volunteer must be properly licensed or certified if the activity requires it, and the protection does not cover harm from willful misconduct, gross negligence, or criminal behavior. Harm caused while operating a vehicle that requires a license or insurance is also excluded.3Office of the Law Revision Counsel. 42 USC Chapter 139 – Volunteer Protection
Calling 911 During a Drug Overdose
A separate branch of Good Samaritan law addresses overdoses, and it works differently from the classic version. As of a 2021 Government Accountability Office report, 47 states and the District of Columbia had enacted overdose Good Samaritan laws, along with naloxone access laws that protect people who administer the opioid-reversal drug.4United States Government Accountability Office. Drug Misuse – Most States Have Good Samaritan Laws and Research Indicates They May Have Positive Effects
The problem these laws address is specific: when someone overdoses, the people nearby often have drugs on them, so calling 911 can feel like inviting arrest. Overdose Good Samaritan laws provide immunity from arrest and prosecution for drug possession and related minor offenses when you call for emergency help in good faith. The person overdosing usually gets the same protection.
The immunity has real limits. It covers possession-level offenses discovered because you sought help, not trafficking, violent crimes, or other serious charges. It also only applies when you’re genuinely seeking medical assistance. Research cited in the GAO report suggests these laws increase the likelihood that bystanders call 911 during overdoses, which matters in a situation where every minute counts.
The Law Protects Helping. It Rarely Requires It.
One thing Good Samaritan laws generally do not do is make you help. In most of the country, you still have no legal obligation to assist a stranger in distress. A handful of states have gone further and created a duty to act in specific situations, such as witnessing someone suffering grave physical harm or certain violent crimes. “Reasonable assistance” in those states can be as basic as calling 911, and penalties for failing to act tend to be minor.5Minnesota Office of the Revisor of Statutes. Minnesota Statutes 604A.01 Good Samaritan Law These duty-to-rescue statutes remain the exception. The default rule almost everywhere is that the law removes a penalty for helping rather than adding one for standing by.
