Can You Temporarily Add Someone Else to Your Car Insurance Policy?

Last Updated on December 11, 2025

It’s usually very simple to temporarily add another driver to your car insurance policy. If you have a friend or family member who will be borrowing your car on a regular basis, you generally need to list them on your policy to be sure they’re covered in an accident.

Most insurers don’t sell a true “one-day” or “weekend-only” policy for your personal car. Instead, they let you add and remove listed drivers as needed, sometimes even for specific dates. Below, we’ll explain how to add someone to your car insurance, when you should (and shouldn’t) do it, and how it can affect your rates.

Key Takeaways

• You can usually temporarily add another driver to your car insurance by calling your insurer or updating your policy online.
• Household members and anyone who regularly drives your car typically must be listed on your policy to avoid coverage issues.
• Occasional drivers who don’t live with you are often covered as “permissive users” and may not need to be added.
• Adding a driver can raise or lower your premium depending on their risk profile, so it’s smart to compare quotes if you’re adding someone long term.

How Do I Add Someone to My Car Insurance?

It’s very easy to add someone to your car insurance. In many cases, you can do this online through your insurer’s website or app, or you can call an insurance agent.

To add a driver, you’ll usually need basic information, such as:

• Full name
• Gender
• Date of birth
• Driver’s license number and issuing state
• Social Security number (sometimes optional)
• Job description or occupation
• How long they’ve had a license
• Any tickets, accidents, or claims in the past three to five years

Once you provide this information, most insurers can add a new driver to your policy in just a few minutes. You can typically:

• Set an effective date for when their coverage should begin
• Schedule a future date to remove them (with some companies)
• Remove them later with another quick call or online change

When Should I Temporarily Add Someone to My Insurance?

You should consider temporarily adding someone when they’ll be using your car regularly, not just once in a while. Common situations include:

• Adult children moving back home. If your adult children move in for a month or two and plan to drive your car frequently, they should usually be listed on your policy.
• A roommate who often drives your vehicle. If a roommate uses your car a few times a week or is the primary driver for certain trips, your insurer will likely want them listed.
• A long-term guest. If a friend or relative is staying with you for several weeks or months and regularly borrowing your car, listing them is the safest move.
• Shared vehicle situations. If two or more people in the same household share the same vehicle, most insurers expect all regular drivers to be listed.

As a general rule, insurers want all household members who regularly drive your vehicle to be listed drivers. If someone lives with you and uses your car more than just occasionally, adding them is usually required.

When Do I Not Need to Add Someone to My Insurance?

There are many situations where a temporary add-on isn’t necessary.

If someone only borrows your car once in a while and does not live with you, most policies automatically cover them as a “permissive user.”

Most insurance policies include a permissive user clause, which usually covers anyone who borrows your car infrequently with your permission. This could be:

• A friend
• A relative
• A partner who doesn’t live with you
• A roommate who rarely uses your car
• A coworker or neighbor

If the person borrowing your car does not live with you and only drives it occasionally, you generally won’t need to add them to your policy.

Permissive users are drivers who are given permission to drive the vehicle by the policyholder. Drivers who fit this definition are usually granted the same liability coverage as the primary driver, although some insurers may:

• Apply higher deductibles or lower coverage limits for permissive users
• Exclude certain high-risk drivers from permissive use
• Require all household members to be listed, even if they don’t drive often

Because rules vary, it’s smart to check your policy language or call your insurer if you know someone will be borrowing your car more than once or twice.

Teen Drivers Learning to Drive

A special case is a teen or young adult who is just starting to drive.

If your child is on a learner’s permit, many insurers automatically cover them while they drive your car under your supervision. Once they get a full license, however, you’ll usually need to add them as a listed driver.

The catch is that adding a teen can significantly increase your premiums because they’re considered high-risk. The good news is that most insurance companies offer special programs and discounts for teen drivers, such as:

• Good student discounts
• Driver education or training discounts
• Telematics or usage-based programs that reward safe driving

If your teen is still practicing with a permit and only drives under your supervision, they may already be covered. Once they’re licensed and start driving on their own—even temporarily—you should talk with your agent about officially adding them to the policy.

How Will Adding Someone to My Policy Affect My Costs?

Adding someone to your insurance policy will usually change your monthly premium—but it doesn’t always increase it. In some cases, adding a low-risk driver can even lower your costs.

When you add a second driver, the insurance company will look at how likely that person is to file a claim. Important factors include:

• Driving history (tickets, accidents, and claims)
• Age and years licensed
• Where they live and park the car
• Credit-based insurance score (in states where allowed)
• How often they’ll drive your vehicle

If the new driver is considered low-risk—for example, an experienced driver with a good record—your premium increase might be minimal or could even go down. On the other hand, adding a high-risk driver (like a teen or someone with multiple accidents) can raise your rates significantly.

If you’re worried about cost, ask your insurer to:

• Quote your policy with and without the additional driver (if allowed)
• List the new driver as “occasional” instead of “primary” when accurate
• Review available discounts you might qualify for together

Alternatives to Temporarily Adding Someone

Depending on your situation, there may be other ways to make sure a driver is covered without permanently changing your policy.

• Relying on their own insurance. If the driver owns a car and has their own policy, your insurance may still be primary on your vehicle, but their policy can provide backup coverage in some situations. This varies by state and policy.
• Non-owner car insurance. A person who frequently borrows cars they don’t own can buy a non-owner policy that follows them from car to car. This can be helpful if they drive different friends’ vehicles.
• Rental or car-sharing coverage. If the guest could instead rent a car or use a car-sharing service, insurance can often be purchased through the rental company or platform for short periods.

These options aren’t perfect substitutes for being listed on your policy, but they may make sense in specific situations. Always confirm with the insurer how coverage would apply before relying on an alternative.

How Should I Shop for Multi-Driver Policies?

If you know another person will be driving your car regularly for the foreseeable future, it may be worth shopping your entire policy as a multi-driver household.

Just as with any other car insurance, you should get quotes from several companies. Each insurer uses its own formula to price risk, based on things like:

• The type of car they drive
• Driving history of everyone listed
• Where you live and park your vehicles
• Annual mileage and how the car is used (commuting, business, pleasure, etc.)

Because every company weighs these factors differently, your price can vary widely from one insurer to another. That’s why it’s so important to compare quotes from multiple companies instead of assuming your current insurer is cheapest.

When you shop around, be sure to ask each agent:

• How they handle permissive users and unlisted household drivers
• How easy it is to temporarily add and remove drivers
• Whether they can schedule temporary coverage dates in advance

FAQs on Temporarily Adding a Driver to Your Car Insurance

Final Word on Adding Someone to Your Car Insurance Temporarily

If you need to temporarily add or remove someone from your car insurance policy, the process is usually quick and straightforward.

If it’s somebody who won’t be driving your vehicle regularly and does not live in your household, they’re often covered under your policy’s permissive use clause and may not need to be added at all. If it’s someone who does live with you or who will be driving your car regularly—even for just a month or two—it’s usually best to list them as a driver to avoid coverage problems after a claim.

When in doubt, call your insurer, explain how often this person will drive your car, and ask whether they must be added to your policy or are already covered as a permissive user. A short phone call now can prevent very expensive surprises later.
