A number of companies now offer GPS devices that can be installed in the car your teen driver will be using to send data to their parents about their child's driving. Most GPS services allow parents to set parameters on their child's driving limits and will receive notifications, via e-mail or text message, if one of the parameters is broken.

The parameters usually include a max speed setting which notifies the parent if their child crosses the speed threshold. Restrictions can also be enforced as to where your child can drive. If you want to see where your child is, many of the teen GPS systems feature a map showing their exact location.

Some GPS programs also offer 24/7 roadside assistance and discounts on your car insurance premiums. No matter how safe your teen driver is, there is always a chance of a flat tire or running out of gas. Some car insurance providers offer discounts if you subscribe to a GPS tracking program.

I am curious to know whether there will be further studies done to see if technology such as GPS devices helps teens become better drivers. I think that parents knowing if their kid is speeding will help them discipline their child, but I'm skeptical that it will prevent the child from speeding the next time they get the keys.
