Auto insurance provider Progressive has announced that its MyRate, a behavior-based car insurance program that lets drivers save money based on how they drive, is now available in Alabama.

Drivers who choose to sign up receive a small wireless device that plugs into a port in their car. The device lets Progressive see how, how much and when the car is being driven. Cars driven less often, in less risky ways and at less risky times of day can receive a lower premium.

According to the company, New Alabama customers can earn a first-term discount of 10% for signing up. Then, when they renew their policy, they could earn up to a 40% discount based on their driving habits. There is also a $30 technology expense each policy period for the cost of the device and data transmission.
