A Good Samaritan law shields you from civil liability when you voluntarily help someone during a genuine medical emergency and something goes wrong. Every state and the District of Columbia has one, and federal statutes add protection for specific situations like defibrillator use, in-flight emergencies, and volunteering for nonprofits. The protection is real but conditional: it covers honest mistakes made in good faith, not reckless behavior, not paid care, and generally not treatment delivered inside a hospital.
Who the Law Protects
The protection applies to people who help without a pre-existing legal obligation to do so. That covers an ordinary bystander with no medical training, and it covers off-duty healthcare workers acting as private citizens: the nurse who stops at a crash on her commute, the physician who sees a diner collapse, the paramedic who witnesses a choking at the grocery store.
The on-duty versus off-duty line matters. During a shift, medical professionals are covered by their employer’s liability insurance and professional malpractice framework. When the shift ends, that coverage ends with it. Good Samaritan laws fill the gap. The protection follows the nature of the act, not the person’s job title.
Federal law adds a layer for volunteers. The Volunteer Protection Act of 1997 shields volunteers of nonprofit organizations and government entities from liability for harm caused while acting within the scope of their volunteer duties, provided they hold any required licenses or certifications and the harm did not result from willful misconduct, gross negligence, or reckless behavior.1Office of the Law Revision Counsel. 42 USC 14503 – Limitation on Liability for Volunteers The statute defines a volunteer as someone receiving no more than $500 per year beyond reimbursement for actual expenses.2Office of the Law Revision Counsel. 42 USC Chapter 139 – Volunteer Protection Act of 1997 One significant carve-out: this federal protection does not apply to harm caused while operating a motor vehicle, vessel, or aircraft.
What You Have to Do to Keep the Protection
Stepping in during an emergency does not automatically trigger immunity. Several conditions have to line up, and failing any one of them can expose you to a lawsuit.
- You must act in good faith, honestly believing your help is needed to prevent death or serious injury.
- You cannot accept or expect payment. Off-duty professionals cannot bill the victim or an insurer for roadside aid. The uncompensated nature of the rescue is the foundation of the immunity.
- There must be an actual emergency with an imminent threat where waiting for professionals would make things worse. Unsolicited advice on a minor complaint doesn’t qualify.
- You cannot have a pre-existing duty to treat that specific person. An on-call physician summoned to a patient at their own hospital is acting professionally, not as a volunteer rescuer.
Courts look favorably on intervention that is spontaneous and altruistic rather than tied to an ongoing professional or personal obligation.
Consent Is Part of the Equation
A conscious, alert person has the right to refuse your help, and overriding that refusal creates serious legal exposure. Providing treatment to someone who has clearly said no can constitute battery, regardless of your intentions. The law treats unauthorized physical contact as harmful whether the outcome was good or bad.
When someone is unconscious or otherwise unable to communicate, implied consent applies: the law presumes a reasonable person would want emergency care. That presumption lets you begin treatment without explicit permission, but it has limits. It cannot override a known refusal. If the victim refused care before losing consciousness, or carries a medical alert bracelet or advance directive indicating they decline certain interventions, treating them against those wishes leaves you exposed.
Simple rule: if they’re awake and tell you to stop, stop. If they’re unconscious and you have no reason to think they’d refuse, you can act. Calling 911 and staying with the person until help arrives is always protected.
Once You Start, You Cannot Just Leave
Beginning emergency care creates a relationship with the victim, and walking away before help arrives can support a negligence claim. Patient abandonment is the unilateral termination of care while the victim still needs it and has not agreed to the care ending. A responder who starts CPR, gets tired, and simply leaves could face liability that Good Samaritan protection would not cover.
You can stop providing care safely in a few situations:
- Paramedics, police, or other professional rescuers arrive and take over.
- The victim regains consciousness, stabilizes, and no longer needs help.
- A conscious victim tells you to stop.
- The scene becomes dangerous to you. No one is required to keep providing aid while a fire spreads or violence breaks out.
The guiding principle: don’t leave the victim worse than you found them. If you have to stop, call for professional help or hand off to someone who can continue.
Conduct That Destroys Your Protection
Immunity is not a blank check. Every state draws a line between an honest mistake and conduct too reckless to shield.
Gross Negligence
Ordinary negligence, like positioning someone’s head poorly during rescue breathing, is exactly what Good Samaritan law protects. Gross negligence is different: a conscious disregard for an obvious risk your actions create. Crossing that line strips the protection entirely.3StatPearls. Good Samaritan Laws Attempting a procedure you have no training to perform is the classic example. Courts ask whether the responder’s actions fell so far below a basic standard of care that the risk of harm was obvious.
Willful or Intentional Misconduct
Deliberately causing harm, or acting with total indifference to whether you cause it, puts you in the same position as someone who never tried to help. That includes using a supposed emergency as cover for inappropriate touching, moving an injured person in a way you know could cause spinal damage, or giving someone a substance you know they’re allergic to.3StatPearls. Good Samaritan Laws
Going Beyond Your Training
A basic first aid course teaches you to stabilize someone and keep them breathing. It does not authorize you to set broken bones, administer prescription medication from the victim’s bag, or attempt invasive procedures. Acting outside your training level exposes you to civil liability and, if you hold a professional license, potential action against it. Do what you know, and nothing more.
Situations With Their Own Rules
Defibrillators
Federal law specifically addresses AED use. Under 42 U.S.C. ยง 238q, any person who uses or attempts to use an AED on someone experiencing a perceived medical emergency is immune from civil liability for any resulting harm. The entity that owns the AED is also protected, provided it notified local emergency responders about the device, maintained and tested it, and trained employees reasonably expected to use it. The usual exclusions apply: no immunity for willful misconduct, gross negligence, or reckless indifference. Licensed health professionals using an AED on the job are also excluded because their liability is governed by malpractice standards instead.4Office of the Law Revision Counsel. 42 USC 238q – Liability Regarding Emergency Use of Automated External Defibrillators
Overdoses and Naloxone
Roughly 40 states have overdose-specific Good Samaritan laws providing some degree of criminal immunity to people who call 911 to report an overdose, even if the caller possesses drugs or paraphernalia at the scene. The strength and scope of these protections vary widely. Some states shield callers from arrest entirely; others offer narrower procedural protection at trial. Some cover the person overdosing, not just the caller. Some condition continued immunity on cooperating with law enforcement or completing treatment.
Separately, 48 states provide civil immunity to laypeople who administer naloxone, the opioid-reversing medication sold under brand names including Narcan. Most of those states also provide some criminal immunity for administering it. If you witness a suspected overdose, the most protected course of action in nearly every jurisdiction is to call 911 and give naloxone if it’s available. Knowing your state’s specifics before you need them is worth the time.
In-Flight Emergencies
A medical emergency on a plane is a problem without an ambulance. The federal Aviation Medical Assistance Act of 1998 shields both the passenger who volunteers help and the airline that asks for it. An air carrier is not liable for damages arising from the acts or omissions of a passenger who renders medical assistance, provided the airline acted in good faith and the passenger is not an employee or agent of the carrier.5Office of the Law Revision Counsel. 49 USC 44701 – General Requirements This federal layer covers U.S.-registered airlines and fills a gap state law might not reach at cruising altitude.
Are You Ever Required to Help?
In most of the country, no. You can walk past someone having a heart attack on the sidewalk without any legal consequence, however uncomfortable that may feel. But roughly a dozen states have enacted some form of duty-to-rescue or duty-to-report law. The requirements vary. Some demand “reasonable assistance,” which can be as simple as calling 911. Others apply only to witnesses of specific violent crimes like sexual assault. Penalties are generally modest, typically misdemeanors with fines rarely exceeding $1,000. The duty almost always comes with a safety exception: you are never required to put yourself in physical danger.
If you’re in a state that requires you to act, Good Samaritan immunity still protects how you act. Being required to help does not raise the bar you have to clear. Honest mistakes made in good faith remain protected.
Where the Protection Doesn’t Reach
These laws are built for emergencies in the real world, not clinical settings. Most do not cover care provided inside hospitals, clinics, or other healthcare facilities, where institutional liability frameworks, professional oversight, and malpractice coverage already apply. One well-known ruling put it bluntly: “the protection of the Good Samaritan Act stops at the door of the hospital.”3StatPearls. Good Samaritan Laws
Other situations typically outside the protection:
- On-duty professionals. If you’re being paid to provide care when the incident happens, your employer’s insurance and professional malpractice standards govern.
- Pre-existing patient relationships. A doctor treating their own patient during a crisis is fulfilling an existing obligation, not volunteering.
- On-call physicians. Being on call creates a duty to respond, which makes the interaction professional even if you were at home when the call came in.
States define each of these boundaries differently, and some are broader than others. The core distinction everywhere is between spontaneous volunteer aid and care delivered as part of a professional arrangement. Good Samaritan law protects the first. The second has its own, separate liability framework.
