Adding a driver to your car insurance policy can be an exciting time, as it is generally associated with tying the knot, getting a new roommate or your teenager passing their driver’s license test. However, what happens to your insurance bill may be exciting or disappointing, depending on how the driver impacts your policy’s change in overall risk. For example, according to data from Quadrant Information Services as of March 2025, married couples who share one insured vehicle pay an average annual rate of $2,495 for full coverage insurance, as compared to the national average of $2,678 per year for single drivers. Conversely, adding a newly licensed 16-year-old causes the average premium for married drivers to jump to $5,757 per year due to the added risk. We outline some common requirements for adding a driver to your insurance policy and identify our picks for the top insurance providers for multi-driver policies.

Can multiple drivers share a car insurance policy?

Yes, multiple drivers can share a car insurance policy under certain conditions. With most auto insurance companies, you are required to list all household members, including spouses and children, on your policy if they have a valid driver’s license and access to your vehicle.

If someone you are not related to lives in your household, you may have to add them as a driver depending on how often they drive your vehicle and your car insurance company’s guidelines. For example, a few companies require roommates to be listed, but others do not have that requirement if your roommate has their own insurance policy.

Don’t be surprised if your insurance company requires you to add all licensed (or permitted) household members to your policy, even if they don’t drive your car. This practice is standard for many carriers because anyone with access to your car keys may pose a risk. However, you may be able to exclude certain household members from your policy, such as non-drivers or drivers with their own insurance policy. For more information, please get in touch with your insurance company directly.

Can you add someone to your car insurance policy that doesn’t live with you?

It’s important to note that you cannot add drivers from outside your household to your car insurance policy unless they regularly drive the vehicle, share ownership of the vehicle or meet your carrier’s specific requirements.

How to add a driver to your car insurance policy

Adding a driver to your car insurance policy is a fairly simple process. Start by reaching out to your insurance agent via phone or email, or, if available, you may be able to make changes to your policy directly through your provider’s website or mobile app. Be ready to answer questions related to the driver’s full name, date of birth, driver’s license number and the reason for adding them.

After adding a driver to your car insurance policy, your provider will likely adjust your premium. With multiple drivers on the same policy, premiums are based on each driver’s risk factors. Insurance companies will pull everyone’s motor vehicle records and claims history to determine overall risk. In turn, insurance companies will calculate your new premium.

If you’ve already pre-paid for six or twelve months of coverage, this update to your premium may come as a surcharge or a refund, depending on how the new driver impacts the overall risk profile of all drivers listed on the policy.

Best car insurance companies for multiple drivers

How to find cheap car insurance for multiple drivers

One of the best ways to find cheap car insurance for two people or more is to shop around with different carriers. Each company has its own risk guidelines, discounts and rate structures that can change how much you pay for car insurance, especially when insuring multiple drivers. Each person’s driving record and claims history will be reviewed, so if one driver has a risky driving history, it could increase the cost of the entire policy or affect eligibility with a particular carrier.

While there is an increased likelihood of risk, a multi-driver policy may also make you eligible for more savings opportunities. You may be able to keep the price low with other discounts, like insuring more than one product, being affiliated with an organization, being a safe driver, having low annual mileage and driving a car with safety features. Additionally, if another household member has a clean record and an experienced driving history, it can beneficially impact the rate.
