despite various state­law bans and nationwide campaigns to prevent texting from behind the wheel, the number of people texting while driving is actually on the rise, a new study suggests. according to the traffic safety administration (tsa), the percentage of drivers who send texts and use mobile devices while on the road has jumped from 0.6% in 2009 to 0.9% in 2010. the news comes as automakers and lawmakers try to bring more awareness to the dangers of distracted driving. in fact, the safety board is working to make cellphone use from talking hands­free to texting illegal in all states. the tsa said that drivers using mobile devices in any situation are four times more likely to have an accident and injure themselves or others.
