Why is insurance so expensive for teenage drivers?

Q. Why is insurance so expensive for teenage drivers?

A. The cost of auto insurance varies from one group of drivers to another because some groups have worse driving records, higher accident rates and more costly accidents than others. The highest insurance rates are paid by any male driver under the age of 25. His rate then hinges on whether he’s married and whether he owns or is the main driver of the car being insured. With the increase in young female drivers in the last twenty years, however, the accident rates between the genders are evening out. Drivers age 15-20 accounted for 12.9 percent of all the drivers involved in fatal crashes and 16 percent of all the drivers involved in police-reported crashes in 2006.
