Drivers on cell phones kill thousands

A new study confirms that the reaction time of cell phone users slows dramatically, increasing the risk of accidents and tying up traffic in general, and when young adults use cell phones while driving, they're as bad as sleepy septuagenarians.

"If you put a 20-year-old driver behind the wheel with a cell phone, their reaction times are the same as a 70-year-old driver who is not using a cell phone," said University of Utah psychology professor David Strayer. "It's like instantly aging a large number of drivers."

The study was announced Tuesday and is detailed in winter issue of the quarterly journal Human Factors.

Traffic jams and death

Cell phone distraction causes 2,600 deaths and 330,000 injuries in the United States every year, according to the journal's publisher, the Human Factors and Ergonomics Society.

The reason is now obvious:

Drivers talking on cell phones were 18 percent slower to react to brake lights, the new study found. In a minor bright note, they kept a 12 percent greater following distance. But they also took 17 percent longer to regain the speed they lost when they braked. That frustrates everyone.

"Once drivers on cell phones hit the brakes, it takes them longer to get back into the normal flow of traffic," Strayer said. "The net result is they are impeding the overall flow of traffic."

Obviamente esto no aplica para los conductores puertorriqueños por que todos sabemos lo excelente que somos como conductores.
