How to Add a Family Member to Your Car Insurance Policy
What happens when you add someone to your policy
When you add a family member to your car insurance policy, the insurance company will run a driving record check on that person and may adjust your premium based on their age, driving history, and the vehicle they will drive. Most insurers let you add a spouse, child, parent, or domestic partner to an existing policy within a few minutes by phone or online. The new person does not need their own policy — they become a listed driver on yours, which means they are covered to drive any vehicle on the policy.
The cost increase depends on who you are adding. A teenage driver typically raises your premium more than an adult with a clean record. A driver with accidents or violations will raise it more still. Some insurers offer discounts if the new driver completes a defensive driving course, which can offset part of the increase.
You should add someone before they drive your car regularly. If they get into an accident and were not listed on the policy, the insurer may deny the claim. If you knowingly left them off to keep the premium lower, the company can cancel your policy.
Key Takeaways
- You can add a spouse, child, parent, or domestic partner to your existing policy by calling your insurer or logging into your online account.

- A teenage driver typically costs more to insure than an adult, but some insurers discount the increase if the teen completes a defensive driving course.
- You must add someone to the policy before they drive your car regularly, or the insurer may deny a claim if they get into an accident.
- If you intentionally leave a regular driver off the policy to lower your premium, the insurer can cancel your coverage.
When to add someone before they start driving
Add a family member to your policy as soon as you know they will drive your car regularly — ideally before their first time behind the wheel. This protects you legally and ensures the insurer will cover any accident they cause. If you wait until after an accident happens, the company will likely deny the claim and may cancel your policy for misrepresenting who drives the vehicle.
"Regularly" means more than once or twice a year. If a relative visits and borrows your car once, you do not need to add them. If your teenager is learning to drive or your adult child moves in and will use a car on the household, add them right away.
Some insurers allow you to add a driver retroactively for a short window — usually 30 days — if you contact them immediately after an accident. This is not may provide and depends on the company's policy. Do not rely on it.
How to add a driver to your policy
Contact your insurance company by phone, through their website, or by visiting an agent in person. Have the new driver's full legal name, date of birth, driver's license number, and driving history ready. The insurer will ask whether they have had any accidents, violations, or insurance claims in the past three to five years.
Most companies can add someone over the phone in five to ten minutes. Your premium will change immediately or on your next billing date, depending on the insurer. You will receive an updated policy document in the mail or by email showing the new driver listed.
If you use an independent agent rather than calling the insurer directly, the agent can shop the change across multiple companies to find you the best rate. This takes longer — usually a few days — but may save you money if another insurer charges less for the new driver you are adding.
What information you need to provide
The insurance company will ask for the new driver's full legal name as it appears on their driver's license, their date of birth, and their driver's license number and state. They will also ask their relationship to you — spouse, child, parent, or other — because some insurers offer discounts for certain relationships or household situations.
You will need to disclose any accidents, moving violations, or insurance claims from the past three to five years. This includes speeding tickets, at-fault accidents, DUIs, and any previous insurance cancellations. The insurer will verify this information by pulling the driver's record from the state motor vehicle department, so lying about it will be caught and can result in policy cancellation.
If the new driver has a suspended or revoked license, most insurers will not add them to your policy. Some will add them but exclude them from coverage — meaning they are listed on the policy but cannot legally drive any vehicle on it — until their license is restored.
How much your premium will increase
The cost increase varies widely by insurer, location, and the driver being added. A teenage driver with a clean record typically raises a family policy by 50 to 100 percent, though some insurers charge more and some less. An adult driver with a clean record might raise it by 10 to 30 percent. A driver with an accident or violation can raise it by 20 to 50 percent or more, depending on how recent and serious the incident was.
Your current premium, the vehicle being driven, and your state's insurance regulations also affect the increase. A sports car costs more to insure than a sedan, and a 16-year-old costs more than a 19-year-old. Some states cap how much insurers can raise rates for young drivers, while others do not.
Ask your insurer for a quote before you commit to adding someone. Many companies will give you the new premium over the phone or online without requiring you to make the change immediately. Compare quotes from at least two insurers if the increase is steep — you may find a better rate elsewhere.
Discounts that can lower the increase
Many insurers offer a discount — usually 5 to 15 percent — if a teenage driver completes an approved defensive driving course. The course teaches collision avoidance and hazard recognition and typically takes four to six hours. Some courses are in-person classroom sessions; others are online. Ask your insurer which courses they recognize before enrolling.
Some companies also discount if the new driver maintains a B average or higher in school, if they have had their license for at least one year without incidents, or if they agree to use a monitoring app that tracks their driving habits and sends reports to you. These discounts vary by insurer and state.
If the new driver is a spouse and you bundle your auto and home insurance with the same company, you may already have a multi-policy discount that reduces the impact of adding them. Ask whether bundling saves you money compared to shopping separately.
What to do if the premium increase is too high
If the cost of adding a family member is more than you can afford, you have several options. First, get quotes from at least three other insurers — rates vary significantly, and another company may charge much less for the same driver. Second, ask about all available discounts: defensive driving courses, good student discounts, usage-based insurance programs, and bundling can all reduce the increase.
Third, consider raising your deductible — the amount you pay out of pocket if you cause an accident. A higher deductible lowers your premium. If you raise it from $500 to $1,000, your monthly cost will drop, but you will pay more if you have an accident. Only raise your deductible if you have savings to cover it.
Fourth, if the new driver will only occasionally use your car, ask whether the insurer offers a "named driver exclusion." This means the driver is listed on your policy but explicitly excluded from coverage — they cannot legally drive any vehicle on the policy. This keeps your premium lower, but it also means any accident they cause will not be covered. This option is risky and should only be used if the person truly will not drive.
Removing a driver from your policy
If a family member no longer lives with you or will not drive your car, contact your insurer and ask to remove them from the policy. This usually lowers your premium. The change takes effect on the date you request it or on your next billing date, depending on the company.
If a driver moves out but you do not remove them from the policy, you are still paying for coverage you do not need. More importantly, if they cause an accident while driving someone else's car, your policy might be involved in the claim, which could complicate things. Remove drivers promptly when their situation changes.
Frequently Asked Questions
Can I add a driver who does not have a license yet?
Most insurers will not add someone who does not have a valid driver's license. Some will add a permit holder if a licensed adult is in the car supervising, but this varies by company. Call your insurer to ask about their policy on permit holders before your teenager starts driving lessons.
What if the new driver has a suspended license?
Most insurers will not add someone with a suspended or revoked license. Some will add them but exclude them from coverage until the license is restored. If you add someone with a suspended license without disclosing it, the insurer can cancel your policy. Contact your insurer and be honest about the situation.
Does adding a spouse to my policy cost more?
Adding a spouse usually costs less than adding a teenage driver, but it depends on their driving record. A spouse with a clean record might raise your premium by 10 to 20 percent. A spouse with accidents or violations could raise it more. Get a quote from your insurer before assuming the cost.
Can I add a roommate or boyfriend to my policy?
Most insurers will not add someone who is not a family member or spouse to your policy. If a roommate or dating partner drives your car regularly, you will need to list them as a household member or explore other options with your insurer. Driving without being listed on the policy can result in a denied claim if there is an accident.
What happens if someone drives my car without being on the policy?
If an unlisted driver causes an accident, the insurer may deny the claim, leaving you responsible for all damages. If you knowingly allowed an unlisted driver to use your car regularly, the company can cancel your policy. Always add anyone who will drive your car more than occasionally.
