It's a sickening thought and still unconfirmed at this point. However, Federal rail investigators have a sneaking suspicion that text messaging may at least be part of the reason for the "human error" of last week's horrific head-on collision between a freight train and commuter train in Southern California.

Word is, the conductor was text messaging back and forth with a 15 year old train enthusiast up until one minute before the crash.

Like I said, it's a sickening thought. The dangers of text messaging while driving have been making headlines around the country in recent months.

Whether this is proven or not about the train accident, it's one heck of a wake-up call for businesses to consider.

- Do your employees really need a texting function on those company-issued cell phones?

- What's your liability, if they cause a terrible accident on your time and with your equipment?

- Can you really afford not to draft an official text messaging policy for employees who operate heavy equipment or drive on the company dime?

- How about a little awareness training?
