Age It is a well-understood fact that the more experience you are on the road, the better driver you will become. At 18, one is still considered relatively inexperienced and more at risk on the road to auto insurance companies. This is the reason why the average auto insurance for an 18-year-old is higher than those who are in their mid-twenties.


An 18-year-old girl could pay lower car insurance rates compared to an 18-year-old-boy. While Some states have outlawed considering gender when calculating car insurance rates, but still one’s gender will generally play a role. According to Insurance Information Institute, there are fewer accidents reports related to women, lower numbers of DUIs, and also less severe accidents than that of men.


To protect your teenage ones, auto insurance companies take almost everything into account, including location, so you can get the best quote possible. The ZIP code one lives in matters when companies verify their address, so if one lives in an area with a low rate of accidents, theft, and vandalism, their car insurance will be more affordable.

Driving Record

Maintaining a clean driving record goes a very long way for an 18-year-old. The fewer claims, accidents reported, or citations one has had, the less of a risk they are seen to the auto insurance company.

Type of Car

Do you know that the type of car your 18-year-old drives can grant and qualify for auto insurance discounts and lower rates? The less expensive the car is, the less expensive the auto insurance will be as well. If a teenager’s car has safety features like the anti-theft technology, the anti-lock brakes, or passive restraints, they could also qualify for discounts.


The Credit scores matter, even at the age of 18. Most big first-time purchases require a credit score. Data from the Federal Trade Commission suggests that drivers with a better credit score file fewer claims. Statistics show that drivers with a higher credit score tend to file lesser claims. Companies also view drivers with higher credit scores as generally more responsible.

Coverage Limits

The limits and deductibles you choose will determine how expensive your car insurance rates are going to be, so it’s important to shop around for policies.
