Drivers using mobile phones were four times more likely to get into accidents than non-cell phone users. Six percent of drivers actively used hand-held phones. A different group, making up four percent, used a hands-free phone. Another recent study, found that cell phone users were more likely to get into an accident than individuals who were legally drunk.
Hands-free units, now being built into higher-end cars, are universally considered safer than handheld phones. In fact, like California, a growing number of states including are banning handheld cell phone use while driving.
Avoid talking while behind the wheel, let voice mail pick up calls, and pull over to a safe spot if you absolutely have to take the call.
