     [1]Sending text messages from your mobile phone while driving is more dangerous than driving after

drinking, which is found by the Transport Research Laboratory (TRL).

      [2]The reaction time of people who sent text messages as they drove slowed by 35%, while the reaction

time of those who had drunk alcohol slowed by 12%."This research shows how dangerous it is to text while

driving," researcher Nick Reed said in a statement. He said drivers who texted were distracted by trying to read

small texts on the phone and by thinking about how to write their messages. And using the phone requires them

to put their hands off the wheel. The combination of factors caused the slowness of reaction and the impairment (减弱) of vehicle control.

     [3]One conclusion researchers made about why texting while driving is so dangerous is the length of time it

takes to write a message. The TRL said that writing a text message behind the wheel took 63 seconds, in which a car travels nearly a mile within town centre speed limits and over a mile within motorway speed limits.

     [4]Nearly half of the 18-to 24-year-olds admitted texting as they drove, another survey discovered.

     [5]The TRL study selected 17 people from the 18-to 24-year-old age group to take part in a simulated (模拟的) road test, in which they were on a variety of roads."The participants in this study were almost unanimous (一致同意的) in their view that texting while driving was the most dangerous action on the road," RAC Director Stephen Glaister said.

      [6] "We need to ensure that drivers who love texting understand that texting is one of the most dangerous

things that can be done while in charge of a car," Glaister said in a statement.
