1. The easiest and cheapest solution is to call your cell phone service provider and ask they block texting access on a certain number. Most plans allow you to do this to as many or as few numbers as are on your plan. A few may even be able to do this for just certain hours in the day.

2. Textecution - this program disables texting when a GPS device detects the phone is travelling at more than 10mph.

3. DriveSafe.ly reads your texts out loud.

4. TXTBlocker allows you to set time and location restrictions for texting or talking on the phone.

These last 3 options have varying prices and work only on certain phones. See this excellent article by the consumerist.com for more information.

Drive safely!
