People who talk on cell phones while driving, even using “hands-free” devices, are as impaired as drunken drivers, researchers said Thursday. The researchers studied 40 volunteers who used a driving simulator four times–while undistracted, using a handheld cell phone, using a hands-free cell phone and while intoxicated to a 0.08 percent blood-alcohol level–the average legal level of impairment in the United States–after drinking vodka and orange juice. Three study participants rear-ended the simulated car in front of them. All were talking on cell phones and none was drunk, the researchers said.
