Teenagers usually pay the most expensive rates for car insurance. In fact, an 18-year-old driver could pay more than $7,000 a year for coverage. But there are cheaper rates available. USAA, for instance, offers these teen policies at about $3,800 a year.

Young drivers between the ages of 16 and 19 have a higher risk of accidents than any other age group. According to the CDC, the crash rate per mile driven is roughly 1.5 times higher for 16-year-olds than for 18- and 19-year-old drivers. 

Our recommendation for cheap insurance for 18-year-olds

Teen drivers pay the highest car insurance rates on average compared to any other age group. Because 18-year-old drivers lack experience behind the wheel, car insurance providers charge much higher rates.

While many 18-year-olds can legally purchase their car insurance policy, staying insured on a parent’s policy is more cost-effective. There are also many ways for 18-year-olds to lower their insurance costs, including shopping around to find the best deal.

Although teens can’t avoid expensive car insurance premiums, we suggest insurance shoppers look into various ways to lower insurance costs. Most insurance providers offer discounts for young drivers, including savings for being a good student or taking a driver’s education course. Shopping around and comparing quotes from several insurance companies can help teens find the most affordable policy. 

What is the cheapest insurance for an 18-year-old?

To help you better understand how much car insurance is for an 18-year-old, we collected quotes from some of the top insurance companies. Based on our analysis, we found that USAA is the cheapest car insurance company for 18-year-olds.

The average rate from USAA is $3,790 per year or $316 per month, which is well below the average of all providers we collected rates from. However, USAA only sells car insurance to military families. If you can’t get insurance through USAA, American Family has comparable rates and no eligibility restrictions. 

While most 18-year-olds can purchase their own car insurance policy, car insurance companies will only sell insurance to drivers who have reached the age of majority in their state. If the age of majority in your state is older than 18, young drivers must be insured on a parent’s policy. 

In the table below, you can see which insurance companies offer the cheapest car insurance for 18-year-olds.

Is car insurance expensive for 18-year-olds?

However, car insurance rates decrease as drivers age, assuming they maintain a good driving record and have a clean claim history.

“Adding a teen to a family’s auto insurance policy can be very expensive due to their inexperience behind the wheel and higher propensity to be involved in an at-fault accident than other demographic groups,” says Mark Friedlander, director of corporate communications for the Insurance Information Institute.

How to get cheap car insurance rates for 18-year-old drivers

There are many ways for 18-year-olds to reduce their car insurance premiums. Here are some tips for saving money:

• Look for discounts: Car insurance discounts can help you get a cheaper premium. Some insurers offer discounts aimed specifically at teen drivers.
• Bundle your policies: Purchasing two or more insurance products from the same insurer, like auto and renters insurance, could help you save money with a bundling discount.
• Choose higher deductibles: For car insurance policies that require a deductible, such as collision insurance and comprehensive insurance, selecting a higher deductible will result in a lower monthly premium. Ensure you can afford a higher deductible.
• Compare quotes from multiple providers: The cost of car insurance can vary between insurance companies, even for the same type and amount of coverage. Compare personalized rate quotes from several insurers to find the most affordable policy. 

Which discounts are available for 18-year-olds?

Eighteen-year-olds can often qualify for car insurance discounts which can reduce their premium. Here are some of the most common discounts car insurance companies offer to 18-year-old drivers:

• Good student discount: If you’re looking for affordable car insurance for 18-year-old college students, consider a good student discount. Full-time high school and college students can qualify for a good student discount if they maintain a good GPA.
• Driver training course discount: Many insurance companies offer a discount to young drivers who complete an approved driver training course or driver’s education course.
• Student away at school discount: Students who attend school at least 100 miles away from home and leave their vehicle behind can qualify for this discount. Oftentimes, it only applies to collision and/or comprehensive insurance.  
• Telematics program discount: Most car insurance companies offer a telematics-based driver rewards program. Your smartphone or device in your car tracks your driving habits, like brake force and speed. Drivers who demonstrate safe habits behind the wheel can earn a discount on their premium. 

Which cars are the cheapest to insure for 18-year-old drivers?

Getting insurance quotes is a good idea before purchasing a car for an 18-year-old. The cost of car insurance can vary significantly depending on your vehicle. In most cases, brand-new cars are more expensive to insure than used cars that have already depreciated.
