Hands-Free Cellphone Devices Don't Aid Road Safety, Study Concludes - New York Times

Hands-Free Cellphone Devices Don't Aid Road Safety, Study Concludes - New York Times: "A study of Australian drivers found that those using cellphones were four times as likely to be involved in a serious crash regardless of whether they used hands-free devices like earpieces or speaker phones that have been perceived as making talking while driving safer.
The study, which is to appear in The British Medical Journal today, is the first of its kind to use actual crash data and cellphone records to show a link between talking on the phone and being seriously injured in an accident.
It is also the first to conclude definitively outside of a laboratory setting that holding a phone to the ear or talking through a hands-free device pose the same risks."
