The Good Samaritan law protects you from civil liability when you voluntarily help someone in an emergency and accidentally make things worse. Every state and the District of Columbia has one, and a handful of federal statutes add protection for specific situations like using a defibrillator or helping during an in-flight medical crisis. The basic bargain is simple: if you act in good faith to help an injured or ill person, you shouldn’t face a lawsuit for honest mistakes made under pressure.
Who the Law Protects
These laws cover anyone who voluntarily steps in during an emergency, regardless of medical training. You don’t need to be a doctor, nurse, or EMT. If you see someone choking in a restaurant and perform the Heimlich maneuver, or pull an unconscious driver from a smoking car, the law is designed to shield you from civil liability for unintentional harm you cause in the process.
Medical professionals get the same protection when they’re acting as volunteers outside the scope of their regular duties. An off-duty nurse performing CPR at a car accident scene qualifies. The key requirement is that no pre-existing duty to treat exists. A physician with an on-call agreement, a paramedic responding to a dispatch, or a doctor treating their own patient already has a professional obligation to provide that care, so Good Samaritan protections don’t apply.
One rule cuts across nearly every state: you can’t expect payment. Rendering emergency aid for compensation disqualifies you from protection.
What Counts as an Emergency
The situation must be a genuine emergency requiring immediate action before professional responders arrive. Car accidents, heart attacks, choking, drowning, severe bleeding, and similar crises all qualify. A scraped knee at a picnic does not. The law contemplates scenarios where waiting for an ambulance could mean the difference between life and death, and the care is expected to happen at the scene rather than in a clinical setting.
Consent matters. If the person is conscious and coherent, you should ask before providing aid. If they’re unconscious, unresponsive, or otherwise unable to communicate, the law treats consent as implied on the assumption that a reasonable person would want help in a life-threatening situation. When a child is the victim and a parent is present, the parent’s consent is required.
The consent rule has teeth in the other direction, too. If a conscious, competent adult tells you not to help, you have to respect that. Overriding someone’s explicit refusal of care strips away your legal protection and could expose you to a claim for battery.
Where the Protection Ends
Good Samaritan immunity is not a blank check. The line between protected mistakes and unprotected ones is the distinction between ordinary negligence and gross negligence.
Ordinary negligence is the kind of error anyone might make in a high-stress emergency. Cracking a rib while performing chest compressions is the textbook example. That’s protected. The legal standard asks whether a reasonable person in the same circumstances, with the same level of training, would have acted similarly.
Gross negligence is something worse: a reckless disregard for the victim’s safety that goes beyond a simple mistake. Attempting surgery in a parking lot, administering random medication you found in someone’s bag, or using clearly excessive force when the situation doesn’t call for it could all cross that line. No state’s Good Samaritan law protects that kind of conduct. Deliberately harming someone is willful misconduct, and that is never protected anywhere.
If You Caused the Emergency
If you created the danger in the first place, you can’t claim Good Samaritan protection for trying to fix it afterward. A driver who causes an accident and then renders aid to the other driver isn’t shielded from the initial negligence that caused the crash.
If You’re Impaired
Providing emergency aid while intoxicated is risky legal territory. Under the federal Volunteer Protection Act, volunteers are explicitly excluded from liability protection if they were under the influence of alcohol or drugs at the time of the incident. At the state level, impaired judgment while rendering aid could easily be characterized as gross negligence or reckless conduct, which would void your protection regardless of your intentions.
You Can’t Walk Away Once You Start
This catches people off guard. You’re not legally required to start helping in most states, but the moment you do, you’ve created a duty of care you can’t simply abandon. If you begin chest compressions and then decide it’s too much effort, you could face liability for abandonment, especially if the victim relied on your help and lost the chance to get aid from someone else.
The standard is straightforward: once you begin providing care, you need to continue until someone with equal or greater training takes over, such as a paramedic, or until continuing would put your own safety at risk. You can hand off; you can’t just stop.
Federal Good Samaritan Protections
State laws handle most emergency rescue scenarios, but three federal statutes fill gaps that state law doesn’t consistently cover.
Automated External Defibrillators
Federal law provides civil immunity for anyone who uses or attempts to use an AED on someone experiencing a perceived medical emergency. The protection extends to the person who used the device and to whoever acquired and placed it in that location, provided the device was properly maintained and local emergency responders were notified of its placement. The usual carve-outs apply: immunity disappears if the harm resulted from willful misconduct, gross negligence, or reckless indifference to the victim’s safety. Health care professionals using an AED within the scope of their employment are excluded, since their professional liability standards already govern that situation.1Office of the Law Revision Counsel. 42 U.S. Code 238q – Liability Regarding Emergency Use of Automated External Defibrillators
In-Flight Medical Emergencies
The Aviation Medical Assistance Act of 1998 protects anyone who provides or attempts to provide medical assistance during an in-flight emergency on a commercial aircraft. You’re shielded from civil liability in both federal and state courts unless you were guilty of gross negligence or willful misconduct. The law also protects the airline itself from liability for seeking a passenger’s help, as long as it in good faith believed the volunteer was medically qualified. Airlines satisfy that requirement simply by asking whether the person who volunteers is a health care provider.2GovInfo. Aviation Medical Assistance Act of 1998
The Volunteer Protection Act
The Volunteer Protection Act of 1997 shields volunteers of nonprofits and government agencies from personal liability for harm caused while acting within the scope of their volunteer responsibilities. The protection applies if the volunteer was properly licensed or certified for the activity (where required), and if the harm wasn’t caused by willful or criminal misconduct, gross negligence, or reckless disregard for the victim’s safety. Volunteers who earn more than $500 per year from the organization (beyond expense reimbursement) don’t qualify. The law also carves out an exception for harm caused while operating a vehicle that requires a license or insurance.3Office of the Law Revision Counsel. 42 USC 14503 – Limitation on Liability for Volunteers
One detail worth knowing: this federal law doesn’t eliminate the organization’s own liability. It protects the individual volunteer, not the nonprofit or government entity that deployed them.
Overdose Good Samaritan Laws
A newer wave of Good Samaritan laws addresses a different fear entirely: not civil lawsuits, but criminal prosecution. As of mid-2024, 48 states and the District of Columbia have enacted overdose-specific Good Samaritan laws. These statutes encourage witnesses to call 911 during a drug overdose by shielding both the caller and the person overdosing from arrest or prosecution for certain drug-related offenses, typically possession of controlled substances, possession of drug paraphernalia, and in some states, underage alcohol possession.
The protections have limits. They generally don’t cover drug trafficking or sales charges, large-quantity possession, outstanding warrants, or probation and parole violations. The purpose is narrow: remove the fear of arrest so that people actually make the call that saves a life. The specific offenses covered and the quantity thresholds vary significantly from state to state.
Breaking a Window to Rescue Someone
Breaking a car window to rescue a child or animal trapped in extreme heat is one of the most common real-world Good Samaritan scenarios people ask about. Roughly a third of states have enacted specific laws granting civil immunity for vehicle forced entry when a person reasonably believes someone inside faces imminent danger of serious harm. These laws typically require that you first confirm the vehicle is locked, call 911 or attempt to contact emergency services, use no more force than necessary, and stay at the scene with the victim until responders arrive.
In states without those specific protections, you could be responsible for the cost of the damage even if you saved a life. Some states split the difference and require the rescuer to cover a portion of the repair cost. The safest approach in any state is to call 911 first and document the situation, including the vehicle’s condition and the victim’s apparent distress, before taking action.
States That Require You to Help
Most states treat the decision to help as entirely voluntary. Good Samaritan laws protect you if you choose to act, but they don’t punish you for standing by and doing nothing. A handful of states break from that rule and impose a limited duty to assist.
These duty-to-rescue laws generally don’t require you to perform CPR or rush into a burning building. The obligation is typically limited to calling 911 or otherwise summoning emergency services when you witness someone suffering serious physical harm, provided you can do so without endangering yourself. Penalties for failing to act are minor. Vermont caps the fine at $100.4Vermont General Assembly. Vermont Statutes 12 VSA 519 Minnesota classifies the violation as a petty misdemeanor.5Minnesota Office of the Revisor of Statutes. Minnesota Statutes 604A.01
The penalties are deliberately light because the point isn’t punishment. It’s a legal floor: when someone is in grave danger and a phone call could save them, the law says you have to at least make the call.
Why the Details Vary by State
The broad principles are consistent nationwide, but what protects you in one state may not protect you in another. Common areas of variation include who qualifies as a protected rescuer (some states limit protection to people with specific certifications like CPR training), what standard of negligence voids the protection, whether medical professionals acting as volunteers in hospitals are covered, and which specific emergencies trigger specialized protections like naloxone administration or AED use. If you want certainty about your own state’s rules, read the statute or ask a local attorney before you need to rely on it.
