"We want the drivers of big rigs and buses and those who share the roads with them to be safe," said U.S. Transportation Secretary Ray LaHood. "This is an important safety step, and we will be taking more to eliminate the threat of distracted driving ( http://www.distraction.gov/ )."
LaHood has made the effort to curtail driver distractions a centerpiece of his tenure as the nation's top transportation official. Some saw his announcement as a step that might ultimately fuel a push to ban cellphone use by all drivers.
LaHood's announcement followed a study released in July ( http://www.washingtonpost.com/wp-dyn/content/article/2009/07/28/AR2009072802101.html ) by Virginia Tech's Transportation Institute that found that when truckers text, they are 23 times more likely to be involved in a crash or near miss.
