Permissive Use: What Happens When You Loan Your Car to a Friend?

What Happens to Your Insurance If You Loan Your Car?

In general, auto insurance policies follow the car, not the driver. Your auto insurance policy can temporarily extend coverage to other drivers who borrow your car based on the permissive use legal mechanism. The extended coverage can apply to liability, collision, and other potential expenses depending on the situation.

But sometimes insurance will NOT cover your friend who’s borrowing your car. In this guide, we will discuss how permissive use works, when it doesn’t, and what auto insurance types might be best for you and your friend.

When Permissive Use Works (Automatic Coverage)

Occasional Lending of Vehicle

If you lend your car out to a friend occasionally, it’s generally fine. This could be for something like a:

  • Weekend road trip
  • Move
  • Designated driver for a carpool

How Primary vs Secondary Coverage Work

Primary coverage refers to the main insurance policy of the car owner. This is the auto insurance policy that will kick in first to cover any eligible expenses, such as bodily injuries or vehicle damages. Coverage goes up to the maximum policy limits.

On the other hand, we have secondary auto insurance coverage. Secondary coverage is the vehicle borrower’s personal auto insurance (or non-owner policy), which acts as backup coverage if claims happen to exceed the owner’s own policy limits.

Explicit vs. Implied Permission

You can either give your friend explicit or implicit permission to borrow your car. Handing someone the keys is obviously the clear, explicit way to give someone permission.

Implicit permission can be trickier. It could be you and your family members who live together just knowing where the key is and handing errands off to each other without asking every single time. This implied permission happens a lot with household members, which can actually be a HUGE problem.

The 5 Major Exceptions to Permissive Use

Don’t expect the permissive use rule to always apply. There are so many exceptions, and if there is an issue, that means your auto insurance company may not pay out in case of a collision or incident. Let’s go over the five major exceptions that you should absolutely understand before lending your vehicle to someone else.

1. Unlisted Household Members

You should be very careful about lending your vehicle to any immediate household members. In-household members can include people like your roommate, partner, children, and family. They must be listed on your primary insurance policy. If you lend your vehicle to an unlisted household member, it is highly likely that your insurance policy will deny the claim.

In general, anyone who lives at the same address as you should be listed on your auto insurance policy. Yes, even if they are not related to you, like a roommate you dislike who runs the occasional errand by car. Even if they only decide to drive your car once a year, listing them is the safest way to secure auto insurance coverage if they get involved in an accident while living with you.

2. Frequent or Regular Drivers

A borrower cannot be the main or frequent user of your vehicle. Let’s say you tell your friend they can use your car every single week, either daily or just a routine day per Monday for work. An auto insurance company might consider your friend as a regular driver who needs to be added to the insurance policy in order to be covered properly.

3. Explicitly Excluded Drivers

Drivers who were deliberately removed from an auto insurance policy are truly in trouble with auto insurance companies. They may have been removed due to dangerous driving habits or high premiums. They will get zero insurance coverage from the insurer as they are blacklisted or removed, even if you technically are permitting them to drive your car.

4. Commercial & Gig Work

Permissive use gets voided instantly if your vehicle borrower is using it for any commercial purposes. Common examples include:

  • DoorDash
  • Uber
  • Business deliveries
  • Commercial transport
  • Grubhub

5. Unlicensed or Impaired Drivers

Do not lend your vehicle to somebody who has no license or is driving illegally or committing a crime. Anyone who is under the influence of drugs or alcohol cannot be legally be given permissive protection, it will be invalidated and claims with the auto insurance company will be denied.

Auto insurance companies take unlicensed drivers extremely seriously. It is considered much riskier than someone who does not own a car or have their own insurance coverage.

Driving without insurance coverage that works is typically considered a misdemeanor (traffic violation), which is technically illegal. Driving without a license is also a criminal misdemeanor. Be very careful if you know the person who is borrowing your vehicle has had traffic misdemeanors in the past. However, check your state law to see whether there are any special rules or exceptions.

4. Hidden Risks for the Car Owner

Loaning a car to someone else has the obvious risk: what if they get into a car crash and get hurt, or injure someone else? The car may also have to be written off as a total loss depending on the collision severity. And in some cases, you might be thinking your car will get stolen or damaged.

There are other hidden risks that may be less obvious if you feel like lending a car is a simple show of trust. It can be a real strain on your finances, your friendship, and your insurance standing if you aren’t careful.

The Premium Penalty

Any car accident that your car gets into, it goes onto your insurance record. Yes, your friend may have been the negligent driver who got into a collision, but you gave them permissive use of your vehicle. The claim gets stuck on your insurance record. You may be forced to deal with premium hikes for years.

If you know someone is a driver who has been in a collision, consider getting them to carry their own insurance policy. If no insurance company is willing to cover them, it may be time to reconsider how risky it is to let them borrow your vehicle.

Reduced Step-Down Limits

Some auto insurance companies will include step-down provisions in their policies for permissive users. These could automatically drop liability limits to state minimums when an unlisted driver is behind the wheel. This means that your insurance coverage, however much you are paying for the policy, could end up providing a lot less coverage than you would expect.

For example, let’s say John carries an auto insurance policy with $400,000 liability coverage. His mom is visiting for a while. She wants to borrow the car for the weekend to try it out. Unfortunately, she gets into a car crash and injures a pedestrian for $200,000. The primary auto insurance policy will only cover a small $25,000 liability expense instead of the usual $400,000. The family ends up having to pay $175,000 out of pocket.

Check your auto insurance policy to see whether they have any step-down provisions. If so, you may want to list the borrower on your policy to ensure there is proper coverage.

Out-of-Pocket Excess

If a friend causes a major accident exceeding the owner's policy limits, the car owner can be personally sued for the remainder if the driver does not carry any insurance policy.

Let’s say your friend hits a pedestrian while driving your car. He carries no insurance at all. Your insurance policy does a good job covering the $100,000 of medical expenses. However, due to the severity of the accident, the injured pedestrian files a lawsuit. Against you for allowing your friend to drive the car negligently. In this case you may be found liable for any out-of-pocket excess, which can be disastrous in a personal injury lawsuit.

Because of this, you may want to mention the possibility of your friend getting non-owner car insurance coverage. It can be affordable while providing significant peace of mind for both you and your friend who’s borrowing from you, ensuring that your friendship can stay intact.

5. When the Borrower Needs Dedicated Coverage

Non-owner car insurance is a lesser known but extremely useful type of car insurance. It can provide coverage for someone who plans to drive but isn’t going to be driving their own car. Their coverage can fill any gaps or cover excess expenses in case your primary auto insurance coverage is not enough.

Frequent Borrowers

A lot of the time when we give a friend or family member in the area use of our vehicles, we end up giving them permission for a long time. This is to be nice, but being nice could violate a car insurance policy term.

If someone borrows vehicles regularly, they should consider a non-owner auto insurance policy. That way they can have proper personal liability protection while driving regardless of who they are borrowing the vehicle from. In some cases the person who is borrowing regularly will not qualify for your coverage unless you have them listed on your insurance policy formally, which can cost more for you.

Car-Sharing Platforms

Peer-to-peer car rentals will not qualify under personal permissive use. Whoever is using the car for commercial purposes absolutely needs to obtain dedicated commercial platform insurance that aligns with the particular situation.

Turo and Getaround are popular car-sharing platforms that are used where people can rent a car for personal reasons.

Long-Term Borrowing

If someone borrows a car from you for more than 30 days (e.g., during a temporary job relocation), they must be added directly as a named driver on your auto insurance policy. Otherwise your auto insurance company may deny any related claims because they will think you are misrepresenting your driving risks.

Permanent Residence Sharers

Usually, people who live with you and borrow your car are not legally required to get their own car insurance policy. However, they need to be officially listed as someone who should be covered on your primary auto insurance policy. Otherwise any claims related to them may be denied.

6. Checklist Before You Hand Over the Keys

Permissive use is great for the occasional favor, but shouldn’t be a blanket pass for just anyone to drive your car. Here are some important questions to ask yourself before you let someone in your driver’s seat.

Does the driver live with you? Do they have a valid license? Are they using it for business? Is this an occasional favor or a regular routine?

Conclusion: Careful Loaning and Coverage

When in doubt, contact your insurance agent to confirm what your policy’s permissive terms are before handing over the keys. That way you know whether your friend needs to be listed on your policy, get a non-owner car insurance policy, or something else to be protected.

It takes only a few minutes to potentially save thousands of dollars in denied claims. Here are the best auto insurance companies for you to get started.
