A Good Samaritan law protects you from being held civilly liable for ordinary mistakes when you voluntarily step in to help someone during a medical emergency. Every state and the District of Columbia has one on the books, and two federal statutes add protection in specific situations. The core bargain is the same across jurisdictions: if you act in good faith, use reasonable care, and don’t expect to be paid, the law will shield you from a negligence lawsuit if your help doesn’t go perfectly.
If you try CPR on a stranger having a heart attack and crack a rib in the process, that’s the kind of outcome these laws exist to cover. Without them, bystanders who could save a life would often hesitate out of fear of being sued.
What You Have to Do to Be Covered
Immunity is not automatic. The specifics vary by state, but the same core conditions appear almost everywhere.
- You acted voluntarily. No one required you to help as part of a job or legal duty.
- You didn’t expect payment. Help has to be gratuitous.
- The situation was a genuine emergency, meaning an immediate threat to someone’s health or life.
- You used reasonable care. You acted the way a sensible person in your position would have acted. You don’t need to perform like a paramedic, but you need to use common sense.
- You had no pre-existing duty to this person. An on-duty EMT answering a dispatch call is doing a job, not acting as a Good Samaritan.
Do You Need the Person’s Permission First?
If the person is conscious and alert, yes. Ask before you touch them, and if they refuse help, respect that. When someone is unconscious, unresponsive, or otherwise unable to communicate, the law treats consent as implied, on the reasoning that a reasonable person would want life-saving help. The same principle extends to minors when no parent or guardian is available.
When the Protection Does Not Apply
Good Samaritan laws cover mistakes, not misconduct. A few situations will strip the shield away.
Gross Negligence and Reckless Conduct
Ordinary negligence is falling short of the care a reasonable person would provide. A cracked rib during CPR or a tourniquet applied too tightly in a panic are honest mistakes under pressure, and the law covers them. Gross negligence is a different animal. It involves more than simple inattention but stops short of trying to cause harm. Moving someone with an obvious spinal injury when there was no immediate reason to, or attempting a procedure you saw on television with no understanding of it, could cross the line. Willful and reckless misconduct goes further, involving actions so unreasonable the person must have known harm was likely. Courts look at whether the rescuer’s behavior was an extreme departure from ordinary care.
Expecting to Be Paid
If you provided aid expecting compensation, most states treat you as a service provider rather than a Good Samaritan. A different standard of care applies, and the immunity doesn’t.
You Already Had a Duty to the Victim
Doctors treating their own patients, on-duty paramedics, and lifeguards watching a pool already have legal duties to provide care. Their professional obligations and malpractice rules govern instead. Many states do extend Good Samaritan protection to healthcare workers who help in emergencies outside their professional setting. An off-duty nurse who stops at a highway accident would generally qualify like any other bystander.
You Walked Away
Once you start helping, you take on a limited duty not to leave the person worse off. If you begin CPR and then abandon the scene before emergency services arrive, with no one else taking over, you can lose your protection. The expectation isn’t that you stay for hours. It’s that you hand off care properly, to arriving paramedics or to another capable person willing to continue.
Two Federal Layers
State law does most of the work. Two federal statutes fill specific gaps.
The Cardiac Arrest Survival Act provides civil immunity when you use an automated external defibrillator on someone in cardiac emergency. The protection covers both the user and the person or organization that acquired and placed the device. It falls away for gross negligence, reckless conduct, or willful misconduct, and it does not apply to licensed health professionals acting within their professional duties or to hospitals and clinics.1Office of the Law Revision Counsel. 42 USC 238q – Liability Regarding Emergency Use of Automated External Defibrillators AEDs are built to be used by people with no medical training; the device analyzes the heart rhythm and decides whether to shock.
The Volunteer Protection Act shields volunteers of nonprofit organizations and government entities from personal liability for harm caused while acting within the scope of their volunteer duties. To qualify, the volunteer must have held any license or certification the activity required, and the harm cannot have come from willful misconduct, gross negligence, or reckless behavior. One important carve-out: the federal law does not cover harm caused while operating a motor vehicle, boat, or aircraft that requires a license or insurance. If you crash a volunteer shuttle van, standard insurance and state liability rules apply.2Office of the Law Revision Counsel. 42 USC 14503 – Limitation on Liability for Volunteers
Calling 911 for a Drug Overdose
A separate category of Good Samaritan protection has emerged for overdose situations. A 2021 Government Accountability Office review found that 47 states and the District of Columbia had enacted laws providing some form of legal protection to people who call 911 to report a drug overdose.3U.S. Government Accountability Office. Drug Misuse: Most States Have Good Samaritan Laws and Research Indicates They May Have Positive Effects
Scope varies. Some states shield both the caller and the victim from arrest and prosecution for low-level drug possession. Others only reduce sentencing exposure or provide an affirmative defense. Most do not protect against charges for drug sales, trafficking, or outstanding warrants. Many of these laws also give civil and criminal immunity to bystanders who administer naloxone, the medication that reverses opioid overdoses.
Are You Ever Required to Help?
In most of the country, no. American law generally follows the rule that you have no legal duty to rescue a stranger. The moral obligation is obvious; the legal one usually isn’t there.
A small number of states are exceptions. They require anyone who witnesses a person in grave physical danger to provide reasonable assistance, as long as doing so wouldn’t put the rescuer at risk. Violations are typically minor offenses, with penalties running from a small fine to a petty misdemeanor. The duty is deliberately limited: often, calling 911 is enough. Separate from these general duty-to-rescue laws, some states require witnesses to specific violent crimes to report them to police.
Certain relationships create a duty to act regardless of state. Parents must help their children. Employers owe duties to employees in some circumstances. If you caused the emergency, you have a duty to render aid. And once you begin helping, you’ve created a duty to continue until help arrives or someone else takes over.
How to Stay Inside the Protection
Knowing the law exists is one thing. Keeping yourself inside its shield is another.
Call 911 first, or have someone else do it while you provide aid. Professional responders are always the right endpoint for a medical crisis, and the fact that you called immediately strengthens your position if your actions are ever questioned.
Provide only the level of care you are actually trained or equipped to deliver. If you’re CPR-certified, perform CPR. If you’re not, keeping the person safe and comfortable until paramedics arrive is still valuable and still protected. The law protects reasonable efforts, not improvised heroics.
Don’t move an injured person unless they face an immediate danger that outweighs the risk of movement, like a fire or oncoming traffic. Stay until help arrives or someone equally capable takes over. And don’t accept or request payment. These aren’t just good habits. They’re the conditions that keep your legal protection intact.
