Driving while chatting on a hands-free cellular phone is just as dangerous as driving while holding a mobile phone, according to a study conducted by the University of Utah in the US.

Talking while driving — even while using a hands-free device — makes drivers four times more likely to have an accident, according to David Strayer, a University of Utah psychology professor who led the study. The study was conducted by tracking drivers' brain activity.

Strayer said chatting on a cellphone while driving cuts the brain's ability to operate a car and process information about traffic by 50 percent.

The study asked 16 pairs of friends to “drive” using a highway-driving simulator while chatting on the phone. Meanwhile, the scientists tracked the brain's activity and eye movements as a variety of situations cropped up, from a car braking suddenly to one abruptly changing lanes and disrupting the flow of traffic.

In each instance, the brain's ability to react was cut in half.

Strayer noted, however, that a telephone conversation does not have the same impact as a conversation with an adult passenger. When driving with a passenger, the driver “has an interest in driving safely. He can say ‘I should stop talking.’”

Cellphones have been outlawed for motorists in only a half-dozen US states, according to the researcher.(AFP)
