Cost of full-coverage car insurance for 18-year-olds with their own policy.

Can an 18-year-old get their own car insurance?

It’s legal for an 18-year-old to get their own car insurance. Unlike younger drivers who are legally minors, 18-year-olds can enter into an insurance agreement without a parent or guardian’s permission.

But if you have an 18-year-old driver in your household, it’s a better idea to add them to your existing policy than for them to get their own. Most companies require you to list all the licensed drivers on your policy anyways. Adding a young driver to your policy will raise your rates, but it will probably still be cheaper than if they got their own policy.

But 18-year-olds who no longer live at home and have their own car will need their own policy. One exception is if they are away at school — many companies offer discounts for families who have a college student who is away at school without a car.

What is the cost to add an 18-year-old to your car insurance?

It’s expensive to add an 18-year-old to your car insurance. But it’s still cheaper to add a teenage driver to your insurance than for them to get their own policy.

How to get the cheapest car insurance for 18 year olds

Car insurance for 18-year-olds is expensive, but it’s still possible to find affordable coverage. You can avoid paying too much for insurance for teens by:

  • Not getting a separate policy: It’s expensive to add an 18-year-old to an existing plan, but it costs much more to get them a separate car insurance policy. Plus, if your 18-year-old has their own car, most insurers offer a discount for insuring more than one vehicle on the same policy.

  • Looking for discounts for teen drivers: Companies sometimes offer discounts for young drivers. These include discounts for good students, completing a new driver course, and away-from-home discounts for students.

  • Considering usage-based programs: Usage-based or telematics programs that monitor driving habits could lower insurance costs for 18-year-olds — as long as they’re safe drivers. 

  • Making sure you don’t have too much insurance: While it’s a good idea to carry comprehensive and collision coverage, they may not be necessary for older cars. If your teen drives an old clunker that isn’t worth much, you can drop those coverages

  • Switching to per-mile insurance: Per-mile insurance plans may be cheaper than a standard policy for 18-year-old drivers who don’t use their cars often. Liberty Mutual, Allstate, and Nationwide all have pay-per-mile car insurance plans, but 18-year-olds will have to get their own per-mile plans.

If you’re still having trouble finding affordable car insurance for an 18-year-old, the most dependable way to ensure you’re getting the lowest rates is to shop around and compare quotes from more than one insurance company in your area.
