Mobile phone users slow traffic down
By Brian Osborne
Sick of traffic congestion? Well, part of the blame needs to go to motorists who talk on mobile phones. At least, that is the conclusion of a study conducted by the University of Utah. The study found that if you use your mobile phone while driving, you are less likely to pass slower vehicles. If you think the study is not talking about you, because you have a hands-free device, then you are wrong. According to previous studies performed by psychology Professor Dave Strayer of the University of Utah, the ultimate distraction for drivers is the conversation - not just holding the mobile phone.
