When Lisa McKee put her son on the family car insurance policy, their premium jumped $450 every sixth months.
That's a lot, but not as much as the average teenage driver. According to Quadrant Information Services and Insurance Quotes, the average premium increases 80 percent when adding a teenage driver.

"I don't think so," said McKee. "We have the same number of cars and there is a slight increase of driving going on, but not $450 worth."
Actually in California, the average policy goes up 88.57 percent. That's 14th in the country with New Hampshire leading the increase of 114.92 percent when adding a teen driver. In Hawaii where state laws limit an insurance company from considering age and gender, the increase is only 16.83 percent.
