Should Your Teen Have Their Own Car Insurance Policy?

A separate policy for a 16-year-old can cost nearly twice as much as adding them to a parent's policy. Here is how the two options compare and the few cases where separate coverage makes sense.

When the quote for adding a teen arrives, some parents wonder whether it would be cheaper, or safer for their own record, to put the teen on a separate policy. In most cases it is neither. Here is how the numbers compare and when separate coverage does make sense.

Family policy vs. separate policy: the numbers

MoneyGeek compared the cost of adding a young driver to a family policy with the cost of a separate individual policy at the cheapest insurer for each age (October 2026):

For a 16-year-old, the separate policy costs about $2,390 more a year. Family policies benefit from multi-car and bundling discounts and from the parents' longer driving history.

Minors can't legally sign binding contracts on their own, so a teen under 18 usually needs a parent or guardian to co-sign a separate policy. In practice, the parent is still involved.

When a separate policy can make sense

  • Your teen owns and titles their own car and is the only person who drives it.
  • Your young adult lives elsewhere and isn't part of your household anymore.
  • Your teen has several accidents or violations. Experian notes that in this case a separate policy, possibly from an insurer that specializes in high-risk drivers, may be worth comparing.

Even then, compare the total household cost both ways before deciding.

Does a separate policy protect the parents?

Not automatically. If your teen still drives cars you own, your policy can still be involved after a crash, and as the owner you may still face liability. Splitting policies is a pricing decision, not a shield. Make sure every policy in the household carries solid liability limits; see how much car insurance you need.

Better ways to save

For most families, the bigger savings come from discounts and smart choices rather than separate policies. See 10 ways to lower car insurance for a teen driver and what adding a teen typically costs.

Frequently asked questions

Can a 16-year-old get their own car insurance?

Generally only with a parent or guardian co-signing, because minors can't sign binding contracts on their own. Once they turn 18, they can buy a policy in their own name.

Will my teen's accident raise my rates if they are on my policy?

Yes, an at-fault accident or ticket by any listed driver can raise the household premium. That is one of the few reasons some families consider separate policies, but compare total costs first.

Does a separate policy protect my assets if my teen crashes?

Not necessarily. If the teen drives a car you own, your insurance may still be involved, and as the vehicle owner you may still face liability. Talk to your insurer before splitting policies.

When should a young adult get their own policy?

Typically when they move out, own their own car or are no longer part of your household. The price gap is much smaller by the mid-20s.
