2．Distracted drivers have been crashing cars since the days of Henry Ford．But today，cell phones are one of the biggest causes of car accidents．
David Strayer，a psychologist at the University of Utah，claimed in a recent report that taking your eyes off the road for a few seconds is just as dangerous as driving drunk．Strayer's research found that talking on a cell phone increases the risk of an accident．"For comparison purposes，someone who's drunk at a 0.08blood alcohol level has a four-time crash increase．So talking on a cell phone is about the same as driving drunk，"he says．"When you're text messaging，the crash risk goes up to eight times．"
So，why can't drivers simply stop reaching for their phones？According to Strayer，the answer lies in dopamine，which sends signals to the brain when a"reward"is received．The same chemical also works for addictions such as gambling and drug use．Therefore，while behind the wheel，people are more likely to pick up their device to check it，Strayer told The Seattle Times．"When the phone goes off，people feel compelled to look at that phone…because it's actually a part of their social network that's reaching out to them，"Strayer said．
And another reason to stay focused while driving？Science shows the front part of the brain is responsible for multitasking，decision making and planning．When drivers use phones or other electronics while also making decisions on the road，they're using the same part of the brain．
"It's a problem of dual tasks"，Strayer explained．"Our brain is overloaded，that's really what happens，"Strayer said．"You're trying to do two separate things at the same time，and there are issues．"
In the US，at least 12states ban the use of handheld cell phones and 41ban text messaging while driving．US lawmakers are currently considering proposals that would ban all use of handheld devices in most situations and prohibit watching video．

A．Because we are easily tired when driving a car．
B．Since we tend to focus on the message from the phone．
C．As the two tasks ask for different parts of our brain．
D．Because the dual tasks make our brain overloaded．
31．What does the passage mainly talk about？A
