Drivers do a lot they should do when driving. One of the deadliest is the phenomenon of texting while driving, which is when folks send and receive SMS messages while behind the wheel.

DriveSafe.ly is a text-to-speech app that promises make driving safer. The free program reads text messages and e-mails aloud and automatically responds without users touching their smartphone. Developed by iSpeech.org founder Heath Ahrens, DriveSafe.ly uses iSpeech.org software as a service (SaaS) to convert text into speech.

In addition to one-touch activation, DriveSafe.ly automatically sends off a response to every incoming e-mail and text, letting senders know that the recipient is driving and will respond upon arrival at his or her destination. Users can customize their auto response message and change it as often as desired.

You can download the application to a RIM Blackberry and Google Android-run smartphone here. Beta versions are also supposed to be available for Windows Mobile and the iPhone.
