More and more is being done everyday to ensure the safety of our nation's teens, and this includes actions working against teens who text while they drive. One of the leading causes of teenage automobile accidents stems from text messaging and performing other keypad related activities that divert the attention and eyes from the road. Oprah even had a live broadcast and created what seemed to be a sort of 'holiday' to bring awareness to and shed some light upon this problem. Now there is an application that parents can use with their teens in order to ensure their safety while driving our dangerous roads.   TextArrest is offering a free month of use for those interested in their services. TextArrest works by using the GPS and Location features of your smartphone to track the location and speed and compare them with the limits which are set on the account. If the current speed is higher than the threshold limit, TextArrest locks the phone by displaying a custom TextArrest lock screen on the top of everything else running on the phone - rendering the user unable to read or to write messages or perform other activities that requires to to look at the device.
