Ask any 18-year-old or their parent, and they’ll tell you car insurance is expensive. In fact, teenagers pay more than any other age group for coverage. That’s the bad news. The good news is that each year of safe driving makes car insurance a little more affordable.
For most 18-year-old drivers, the cheapest way to get insurance is to be added to a parent’s policy. On average, an 18-year-old female driver pays $3,349 per year for full coverage, while a male driver the same age pays $3,607 annually.
In some cases, however, a teen may want or need to obtain their own coverage, which means paying more. An 18-year-old female driver with her own policy pays $4,956 annually for full coverage, while a male the same age pays $5,543 per year.
Either way, 18-year-olds pay considerably more per year for car insurance than adults – the national average for full coverage is just $1,895 per year.
“While teen drivers will pay more for car insurance even with a clean driving record, steering clear of at-fault crashes and citations will help them keep their insurance premiums lower,” says Carole Walker, the Rocky Mountain Insurance Information Association executive director.

Why is car insurance expensive for 18-year-olds?
When it comes to car insurance, teenagers — those aged 16 to 19 — pay the most because they’re the riskiest age group to insure. According to the IIHS, teens are three times as likely to be involved in a fatal accident as older drivers. However, with every year of experience gained, insurance rates slowly decline for teens who drive safely and avoid citations and accidents.
Car insurance for young drivers is much cheaper when parents add the teen to their existing policy. You’ll see how much it costs to add a teen driver to a parent policy and how much you save in the chart below.
| Gender | 18-year-old policy | Parent’s policy with a teen | Savings |
|---|---|---|---|
| Female | $4,956 | $3,349 | $1,607 |
| Male | $5,543 | $3,607 | $1,936 |

Best car insurance companies for 18-year-olds
The best insurer for your teen driver will vary depending on a wide variety of factors related to their driving record and the vehicles you are insuring. Our analysts looked at the data, and these are the cheapest insurers for 18-year-old drivers:
Female drivers: Keeping teens on your policy is cheaper than getting them their own policy. Nationwide had the cheapest insurance for a female 18-year-old on their parent’s policy at $2,360. GEICO ($2,429) was No. 2, and State Farm ($2,775) rounded out the top three.
If a female teen moves to their own policy, the cost of coverage gets higher. Travelers is the cheapest option at $4,046, with GEICO ($4,438) in second and State Farm ($4,624) grabbed third.
Male drivers: Teen males are typically more expensive to insure than teen females, and the data backs this up. Nationwide was the cheapest insurer for a male teen on their parent’s policy at $2,506 yearly. GEICO was second ($2,566), and State Farm ($3,072) was third.
The cheapest option for a teen male on his own policy was Travelers, at $4,546. GEICO ($4,851) took second place, and State Farm ($5,531) finished third.
It should be noted that USAA was the cheapest option in each category, but because it is only available to military families, we left it out of the rankings. If your teen qualifies for USAA coverage, they can get the cheapest rates from a well-reviewed insurance company.
Used cars that cost the least to insure for 18-year-olds
The cost of auto insurance depends on many factors, including age, gender, and place of residence. However, the type of vehicle you drive is also a factor, regardless of age. And used vehicles are cheaper than new models, both to purchase and to insure.
The following are some of the cheapest used cars that cost the least to insure for a teen driver:
| Make and model | Full coverage cost | State minimum liability cost |
|---|---|---|
| 2017 Toyota RAV4 | $6,535 | $2,486 |
| 2018 Mazda CX-5 | $6,495 | $2,486 |
| 2017 Honda CR-V | $6,120 | $2,448 |
| 2021 Toyota Corolla | $8,347 | $2,686 |
| 2019 Mazda3 | $7,969 | $2,741 |
| 2018 Honda Accord | $7,308 | $2,534 |
| 2017 Toyota Prius | $7,329 | $2,564 |
| 2020 Honda Civic | $7,775 | $2,604 |
| 2019 Chevrolet Equinox | $7,203 | $2,540 |
What are the best cars for an 18-year-old?
The best vehicle for an 18-year-old will vary, but in general, avoid luxury and sports cars to keep your premium affordable. Consider sedans, minivans and small to midsize SUVs, which tend to be cheaper to insure and often top best cars for teens lists.
A vehicle loaded with advanced safety features will result in a number of discounts that can lower your premium while keeping your teen safe.
Another way to keep your insurance affordable is to put your teen in an older vehicle that you would replace if it were stolen or in an accident. Carrying liability only on a teen’s vehicle will help keep your coverage reasonable.
How do you get cheaper car insurance for 18-year-olds?
Rather than skimping on coverage, a better idea is to maximize discounts and shop around regularly for the best insurance coverage. Accident- and ticket-free driving, comparison shopping and maximizing discounts will help you find the cheapest car insurance rates for teens.
“Many big car insurance companies offer discounts to good students. Students are eligible for discounts if they have excellent academic performance, such as a high GPA or high test scores on SAT or ACT,” says Associate Professor Ting Liu of the College of Arts and Sciences at Stony Brook University.
“Some companies offer multiple policy discounts. For example, if a student needs renters insurance and car insurance, buying the two policies from the same company is a good idea and asking for a multiple policy discount.”
Best ways 18-year-olds can lower car insurance costs
Even though 18-year-olds pay hundreds more for car insurance than older drivers, there are ways to reduce the cost.
- Obtain coverage through a parent or guardian. Adding a child to the family car insurance policy can cost hundreds or thousands of dollars less than if a teen purchases their own coverage.
- Choose an affordable make and model. Popular models like the Toyota RAV-4, Kia Soul, and Mazda CX-5 are among the cheapest vehicles for teens to insure.
- Raise your deductible: If you can afford to do so, choosing a higher deductible for comprehensive and collision insurance can lead to a lower premium.
- Drop unnecessary coverage: If your teen drives an older vehicle that has depreciated significantly in value and is paid off, it may no longer be worth carrying comprehensive and collision insurance. Liability insurance is still a must.
- Look for car insurance discounts for teens. Two of the most common are:
- Good student discount: A savings of up to 16% may be available for drivers who maintain a 3.0 or “B” average in the classroom, but the average is 7%.
- Student-away discount: College students who live away from home could qualify for this discount.
Shop around for car insurance for 18-year-olds
Adding an 18-year-old to a parent’s insurance policy or getting their own car insurance policy is costly. The best way to minimize the pain is to shop around. Compare car insurance quotes from multiple insurance companies. Each insurer uses its own method for calculating what you pay, so prices for the same policy vary.
There is some good news. Car insurance gets cheaper as you age. Average rates by age show that premiums decrease significantly when drivers turn 26. CarInsurance.com has guides for car insurance for 16-year-olds, 17-year-olds, and 19-year-olds that break down rates for teens.
FAQs: How much is insurance for 18-year-olds?
Why is car insurance for 18-year-olds expensive?
The truth is that teens are not great drivers and often take unnecessary risks behind the wheel. According to the Insurance Institute for Highway Safety (IIHS), teenagers are disproportionately involved in car accidents, even though they drive less than most other age groups. The crash rate for 16- to 19-year-olds is nearly four times the rate for drivers 20 and older.
Young drivers lack the experience that older drivers have, which leads to accidents and claims, which will always raise your premium. Rates will drop if a teen driver keeps it safe out on the road and will hit the normal range around age 25.
Do 18-year-olds have to buy full coverage insurance?
No, there is no state that requires drivers to carry full coverage car insurance. Almost all of them require that you carry a certain amount of liability coverage; the required amount varies by state. If your teen is an older vehicle that you would replace if it were in an accident, there is probably no need to carry full coverage car insurance.
However, if you have a loan or lease on the vehicle your teen is driving, your lender will require that you carry full coverage to protect their investment.
Does an 18-year-old need car insurance to get a license?
No, you do not need car insurance to get a driver’s license. Many people with a driver’s license don’t own a car or have insurance coverage. However, in most states, if you want to legally drive or register a vehicle, you will need car insurance.
Most states require you to carry a certain amount of liability insurance to register a car and drive it legally on the street.
What are the rules for 18-year-old drivers?
The rules of the road are the same for everyone, regardless of age. Teen drivers need to keep their driving records clean to get the best rates for coverage. If a teen gets a speeding ticket or accident on their record, their insurance cost will skyrocket.
Can an 18-year-old have their own policy?
In most states, the answer is yes, but it depends on your state’s “age of majority.” In almost all states, that age is 18, but it may be higher in some states; for example, in Alabama, it is 19.
The age of majority is when a person can legally enter into a contract on their own, and an insurance policy is considered a contract which means most 18-year-olds will be able to purchase their own insurance coverage.
Can an 18-year-old own a car?
Yes, in most states, but again, it depends on your state. If you are paying cash for a vehicle and will own it outright, then owning a car as an 18-year-old is possible in most states.
However, if you need to finance the vehicle, the answer may vary. Purchasing a vehicle typically involves some type of contract if you are financing or leasing a vehicle, and you must be the age of majority in your state to enter into a contract. In most states, the age of majority is 18, but it can vary.
