Most drivers who are 18 have had two years of driving under their belts, and that experience begins to pay off in lower car insurance rates. The average car insurance rate for an 18-year-old on their own policy is $5,565 yearly for full coverage.
That rate is $3,883 higher than the national average of $1,682 for 40-year-old drivers. However, the car insurance rate for 18-year-olds is significantly lower than that for 16-year-olds ($7,625 per year and $635 a month) and for 17-year-old drivers ($6,272 per year and $523 per month).
As drivers gain more experience and improve their behind-the-wheel performance, car insurance rates are likely to drop, says Carole Walker, the Rocky Mountain Insurance Information Association executive director.
“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,” she says.

“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, it is a good idea to buy the two policies from the same company and ask for a multiple policy discount.”
