You’ve probably seen the ads. A young man who has difficulty talking is reaching out to the rest of us, to warn us — don’t text while you drive. He was brain-injured in a crash, where a moment’s inattention resulted in a lifetime of dealing with serious brain damage.

No text or other message is worth risking your life, or harming your passengers or other people who share the roads. Imagine how horrible you would feel if you killed someone inadvertently just because you couldn’t wait to send a text.

AT&T has launched a national drive, to urge everyone to pledge not to text and drive. It’s a good idea, even if they are motivated partly because they want to stave off laws that prohibit texting and driving.

Don’t let your last text end with a crash.
