Family liability when an older relative keeps driving

Family members are most exposed when they own the car, share ownership of it, pay to keep it on the road, or hand over keys while knowing the driver is no longer safe. In those situations an injured person's lawyer can try a claim called negligent entrustment, which is aimed at the family member's own conduct, not the driver's. A relative who has no ownership, no keys and no control over the car is in a very different position, though the rules differ by state and a plaintiff may name anyone who looks like a source of money.

That is the legal picture in broad strokes. The practical picture is that a family's best protection is the same as its best course of action: notice what is changing, get an objective evaluation, adjust the driving, and keep a record that shows you did.

What negligent entrustment actually requires

Negligent entrustment is a form of ordinary negligence. The injured person does not argue that the family member drove badly. The argument is that the family member let someone drive a vehicle when they knew, or should have known, that the person was unfit to do so, and that decision helped cause the harm.

California's jury instruction on the subject is a useful example, and an appeals court described how a jury applied it in Ghezavat v. Harris, decided September 27, 2019. The jury had to find that the defendant knew or should have known that the driver was incompetent or unfit, that the defendant permitted the driver to use the vehicle, and that permitting the use was a substantial factor in causing the deaths. Other states phrase the elements differently and set different thresholds for what counts as knowing, so this is an illustration of the logic, not a map of every state.

Three ideas carry most of the weight in a claim like this:

• Knowledge. What did the family member know about the driver's condition, and when? A physician's warning, a diagnosis, a string of minor crashes or a conversation in which the driver admitted getting lost all go to this element.
• Power to permit or forbid. The claim targets someone who could have said no. The Ghezavat court, quoting an earlier California Supreme Court decision, put it this way: "the power to permit is the correlative of the power to forbid."
• Causation. The decision to let the person drive has to be a substantial factor in the harm. A relative who merely worried and had no say is much harder to link to the crash than the one who held the keys.

A real case that shows how it plays out

Ghezavat did not involve an older driver, but the family logic transfers. The driver was an adult son with a seizure disorder who had a seizure at the wheel of a truck and killed two people. The truck was jointly owned by the driver and his father. The father had co-signed the loan, made some of the payments, paid for the insurance and registration, and was a registered owner. The court's opinion records that the father knew by June 2011 that his son had a seizure disorder after a grand mal seizure on a train, researched the condition within days, did not know whether his son kept driving but thought it possible, and took no step to dissuade him, such as canceling the insurance. The son had a second seizure on a train on July 30, and the fatal crash came in November 2011.

The jury assigned 90 percent of the fault to the son and 10 percent to the father, and the judgment against the father was $388,400. The Court of Appeal affirmed. The father argued that he had no power to forbid his son's use of a truck they co-owned. The court rejected a special instruction on that point, saying the standard jury instruction adequately told jurors that the father was not liable if he did not permit the use.

The details that mattered were exactly the ones families control: documented knowledge of a medical condition, some control over the vehicle, and no action. A parent who had taken the keys, cancelled the insurance or put the registration in the son's sole name before the crash would have been in a different position. The case is also a reminder that a plaintiff can recover from more than one person for one crash. Ten percent of the fault was still a six-figure judgment.

Who is exposed, and who usually is not

The following table sorts the roles. It describes how courts think about these relationships in general; the outcome in your state may differ, and a licensed attorney is the person to ask about a specific family.

The "family purpose doctrine" is a separate theory some states apply. The Legal Information Institute's summary says the family purpose doctrine holds a vehicle owner liable for damage caused by family members using the vehicle, whether or not the owner gave permission in the particular case, and that it varies by state, with some limiting it to parents and children and others extending it. It matters more for a household where a family car is available to several relatives. It is not an entrustment theory, since it does not turn on what the owner knew about the driver. Several states have also replaced or supplemented it with owner liability statutes. Our article on lending your car: owner liability and negligent entrustment covers those routes and how the owner's own insurance fits in.

Which insurance pays first

When an older driver causes a crash, money comes from a sequence of sources, and the family usually only comes into play if the first ones fall short.

1. The liability coverage on the car involved. Insurance generally follows the car, so the policy covering the vehicle pays for injuries and damage to others up to its liability limits. If the older relative owns the car and is the named insured, that is their policy.
2. The driver's own assets. If damages exceed the limits, the driver is personally responsible for the excess. For a person whose home and savings are exposed, that can mean the family's inheritance. The analysis in what happens when damages exceed your liability limits shows how this works.
3. An umbrella policy, if the relative has one. An umbrella policy sits above auto liability limits and usually requires certain minimum underlying limits. See adding an umbrella policy to your auto bundle: what it requires.
4. Other defendants. If a family member also faces an entrustment claim, their own policies may or may not respond. Homeowners and renters liability coverage typically excludes liability arising from motor vehicles, so do not assume it will pick up a claim like this. Ask the insurer whether any umbrella or personal liability policy you hold would respond to such a claim, and read the exclusions.

Two common mistakes make this worse:

• Letting liability limits lag. An older couple that raised their limits once, decades ago, may be carrying state minimums or the limits they chose in a very different period. Review them while the relative is still driving. how much liability coverage do you need? offers a way to approach the choice.
• Using an exclusion as a safety measure. An excluded driver endorsement removes coverage entirely for the named person. If the relative then drives the car, as people sometimes do in an emergency, there is no insurance for the crash, and the family member who allowed it faces a harder situation than one who had kept an insured driver. excluded drivers: what a named-driver exclusion does in a crash explains what an exclusion does and does not do.

Does reporting to the DMV protect the family?

A DMV report can be a legitimate step, but nothing in the sources checked for this article says it shifts legal responsibility, and the safest way to think about it is as a way to get an objective evaluation, not as a shield.

The California DMV's senior driver guide lists the sources that can prompt a reexamination: a doctor, who it says is required by law to report medical conditions involving loss of consciousness or control, along with others that may affect safe driving; emergency personnel; a family member; a peace officer; the renewal application; and the driving record. It says family members, friends or neighbors may contact the DMV to express concern about someone's ability to drive safely, and that DMV may place restrictions on a license based on information shared by a family member, doctor or law enforcement. It also states the restrictions are meant to be reasonable and necessary for safety.

Several practical points follow:

• A report starts a process in which the licensing agency evaluates the driver. Results vary, and the agency may decide the driver can keep a license, with or without restrictions.
• Rules differ widely. Some states require physicians to report certain conditions, others permit reporting, and some give physicians legal protection for reporting while others do not. Dr. Adam Rosenbluth, writing for AARP in an August 2024 column, notes that in some states doctors must notify the DMV about conditions that interfere with driving and that some states protect doctors from liability for doing so, while New York, where he practices, does not. Our guides on physician reporting and medical review for older drivers and older driver license renewal rules by state give the state picture.
• A report does not cancel the car's insurance or take the relative off the policy. If the license is suspended, the insurer's questions change, and the family has to decide who drives the car.
• Whether the fact that you reported helps you in a later lawsuit, or the fact that you knew hurts you, is a question for a licensed attorney in your state. Both can be true at once.

Documenting concerns, and acting on them

Notes about what you have seen are useful, and they are not a substitute for action. A file that shows you knew and did nothing helps no one. A file that shows what you noticed, who you consulted and what changed afterward is a record of reasonable care.

A short, factual log is enough. Include:

1. Dated observations. "Mom missed a stop sign on Elm Street on March 3. She said she did not see it." AARP's warning signs list gives categories to watch for: delayed responses, getting lost in familiar places, trouble judging gaps, failing to stop at signs or signals, and scrapes or dents on the car, garage or mailbox.
2. Evidence of incidents. Photos of damage, tickets or warnings, and repair estimates for minor crashes.
3. Professional input. Notes from a physician conversation, the results of a driving evaluation, and a medication review. The California DMV page says occupational therapy practitioners trained in driving rehabilitation can evaluate whether someone can operate a vehicle safely and help with the move to other transportation.
4. Decisions and dates. "We agreed Dad would stop driving at night starting June 1." "Keys moved to the daughter's house on August 12."

Tools that work better than a confrontation

Families usually get further with a structured process than with an argument. These steps run from least to most intrusive.

1. Ride along. Spend an afternoon as a passenger on the routes the person drives. Rosenbluth's column suggests checking whether the driver misses full stops or red lights, changes lanes without looking, or has trouble after dark.
2. Start with a question. The column suggests opening with "what do you think of your driving?" and, if the answer is defensive, stepping back and proposing a family meeting with the doctor or an evaluation at a driving school. He adds that most older people with health problems stop driving too late, after an accident.
3. Get a professional evaluation. A driving rehabilitation specialist can assess skills on the road and in the clinic and recommend vehicle changes, limits or retirement from driving. It is an objective voice that is not a family member.
4. Talk to the physician. Medications and conditions matter. Ask the doctor whether any prescription affects driving, and whether the doctor considers the person safe.
5. Narrow the driving. Many people can keep driving with limits: daylight only, local trips, no freeways. The California DMV lists such restrictions among the common ones for senior drivers. IIHS notes that surveys show many older drivers already drive fewer miles and avoid night driving or other challenging situations.
6. Agree on a stopping point in writing. For progressive conditions, it is easier to agree in advance on triggers (a crash, a physician's recommendation, a failed evaluation) than to argue after one.
7. Change the car's availability. If the relative should stop, remove the keys, sell or move the car, or end the registration as appropriate, and replace the driving with rides. Rosenbluth stresses addressing the problem with a solution, since a driver loses access to appointments, shopping and friends.

For the insurance side of each step, insurance decisions for aging drivers and their families covers listing drivers, storage and cancellation.

Ethical duty and legal duty are different questions

The law asks narrow questions: who owned or controlled the car, what each person knew, and whether their conduct was reasonable. A family member who owns nothing and controls nothing might owe no legal duty and still feel a moral one. A person who owns the car might feel the moral pull weakly and still carry the legal risk.

The ethical question is simpler and tougher: if this driver hurt a child on a school route, would you be able to say you did what you could? The answer is usually to act on the same list as above. The Insurance Institute for Highway Safety reports that in 2024, 70 percent of the people killed in crashes involving drivers 70 or older were the older drivers themselves (57 percent) or their passengers (13 percent), which is a reminder that the person most at risk is often the one behind the wheel.

A worked example with invented numbers

Say Margaret, 84, owns a sedan insured with $100,000 per person and $300,000 per accident bodily injury limits. Her daughter Ana knows Margaret has early memory loss and has gotten lost twice. After a crash that injures a pedestrian, the injured person's damages are valued at $450,000.

• Variation A. Margaret owns and insures the car alone; Ana lives in another state, owns nothing and never held keys. The policy pays up to its $100,000 per-person limit. The remaining $350,000 is Margaret's personal exposure, which in practice reaches her estate. Ana is an unlikely defendant.
• Variation B. Ana is a co-owner and pays the insurance and registration from her own account. The insurer still pays $100,000. A plaintiff now has a plausible argument that Ana had the power to forbid the use and knew about the condition. If a jury finds Ana's conduct was a cause, she could be allocated some share of the fault in addition to the policy limits.
• Variation C. Ana lends Margaret her own car after the physician told the family that driving was unsafe. Ana's policy responds first as owner's coverage, and the facts line up the way plaintiffs want: ownership, knowledge, permission.

The numbers are hypothetical, and a real allocation depends on the state's rules and the jury. The pattern is the lesson: exposure grows with ownership, control and documented knowledge, and it shrinks when a family acts on what it knows.

Common questions

Can I be sued if I do not own my parent's car?

A plaintiff can name anyone, but a claim based on negligent entrustment depends on the defendant having the power to permit or forbid the use. Without ownership or control, the claim is weaker. State law varies, and a licensed attorney can say what applies where your parent lives.

Does being listed on my parent's policy make me responsible?

Being a listed driver or named insured is about coverage, not about responsibility for another driver. It can matter if you are also an owner or if you hold the keys. Ask the insurer what your status is and why.

What if my parent refuses to stop and there is no medical diagnosis?

Use the tools in order: an objective evaluation, the physician, then limits on the driving. If safety is at stake, a request to the licensing agency is an option. California, for example, says family members may contact the DMV with concerns. Check how your parent's state handles such requests.

Should I cancel the insurance to make them stop?

Usually not. Letting the policy lapse leaves the driver, and any victim, with no coverage if they drive anyway, and registered cars generally need continuous insurance. Taking the car away is a more reliable step than cancelling the policy.

Key takeaways

• Exposure comes mainly from ownership, control and documented knowledge, which is why a co-owner who paid the insurance was held partly responsible in Ghezavat v. Harris (2019).
• Insurance follows the car, and the family's risk is mostly what exceeds the limits, so review the older driver's liability limits while they still drive.
• A DMV report asks the licensing agency to evaluate the driver; it should not be treated as a legal shield, and state rules on reporting differ.
• Keep a dated, factual log, and pair it with action: an evaluation, a doctor's input, and agreed limits.
• Legal duty and ethical duty are separate questions, and the same steps serve both.
