SEATTLE - Curfews and strict rules are part of the teen driving experience. But a new system allows parents to make sure kids follow those rules.

It's called Teensurance, and it's a little black box with a GPS device that's installed under the dash.

If your teen driver speeds or breaks curfew, for example, Teensurance will give the parents a call, telling them what your teen is doing.

Safeco Insurance is rolling out the device. For a monthly fee, parents can monitor their teenaged driver's speed, and where they are, in real time, both online and on their cell phones.

"I can set up Teensurance, for example, to notify me every morning when my daughter reaches school," said Teensurance Project Manager Matt Gertmenian.

Safeco says the device will not lower insurance rates and insists the company has no plans to share with police any information stored.

"Parents have a responsibility over you," says Safeco's Jim Havens. "They should know where you're at and especially if something happens they know where you're at and they know that you're safe."

The cost is $14.99 a month through Safeco. In addition, Teensurance also lets parents program their cell phones to unlock the car if their teenager gets locked out.

Safeco launches the service at the end of the month.
