Parents in three Midwestern states will soon know just how good or bad their kids' driving is when their children take the car for a spin (疾驶).

Starting today, American Family Insurance is offering customers with teen drivers free cameras that record what happens when a sudden change in the car's movement occurs.

The cameras record the action inside and in front of the car in 20 - second audio - video clips (剪辑). The clips are then transmitted to Drive Cam, a San Diego company that analyzes the clips for risky behavior.

Among things the analysts look for is the response time of the drivers and if they are paying attention to the road. Parents can receive a report on their kids' driving and view the clips on a home computer.

Car accidents are the leading cause of death among U. S. teens, according to the NHTSA

(National Highway Traffic Safety Administration).

"There will be fewer accidents," Rick Fetherston, vice president at American Family said of the new system. American Family will test the system out by offering it for free for one year to 30.000 families in Wisconsin, Indiana and Minnesota to see whether the system results in fewer accidents. If the system is proven to prevent accidents, customers who volunteer to use it might see their insurance premiums (保险费) drop. The company would not be viewing the videos or individual score cars, unless there is an accident.

Bruce Moeller, president of Drive Cam, says his company's system is already being used by companies with lots of cars. "Some of our customers are reporting a 30% to 90% reduction in their risky driver events," Moeller says.

But a lawyer in Minneapolis says. "If I felt I needed a camera in the car to watch over my kids, I shouldn't be letting them drive."

American Family tested the system in two high schools in Minnesota and Wisconsin.

Megan Ireland, 17, said the camera caught her stopping too late and taking turns too fast. The student at Prior Lake High School in Savage, Minn., said she didn't like it because she felt it invaded her privacy (侵犯隐私) but has warmed up to the system. "Now I don't really have a problem with it because it's made me a better driver," she says. "For real."
