NEW YORK (TheStreet) -- Adding a teenager to your auto insurance can raise your bills by 79%.
That number comes from InsuranceQuotes.com, which says car insurance costs that much more after a typical married couple adds a teen driver to their policy.
Teenage boys are much more expensive to insure than teenage girls, InsuranceQuotes.com says in a report. Boys add 92% to your premiums, and girls add 67%. The good news is that the premium increases decline each year, from 96% for 16-year-olds to 58% for 19-year-olds.
Living in some states can really dent your wallet with a teen driver. The study notes that premiums double in seven states: New Hampshire (plus 111%), Rhode Island (plus 107%), Maine (plus 107%), Wyoming (plus 106%), Connecticut (plus 102%), Illinois (plus 101%) and Oregon (plus 101%).
The report says the lowest increases are in Hawaii (plus 17%), New York (plus 53%) and Michigan (plus 57%). Hawaii is the lone state in the union that bans insurance companies from framing insurance rates around a driver’s age or gender.

If you’re saddled with higher rates due to a teenage driver, there are a few steps you can take to ease the damage.
"A great strategy for lowering car insurance costs is to sign up for pay-as-you-drive car insurance," said Laura Adams, a senior analyst at InsuranceQuotes.com. "These programs allow companies to track your driving habits and can lead to significant discounts, especially if you're a safe driver who doesn't rack up too many miles. Teens who excel in the classroom should also take advantage of good student discounts."
