A recent study has found drivers with passengers were almost 60% more likely to have a crash resulting in hospitalization than those who hit the open road alone. The study, conducted by Suzanne McEvoy, of the George Institute for International Health, found crashes more than doubled with two or more passengers.
In the study, over 30% of drivers listed at least one distracting activity at the time of the crash, and driver distraction was reported to have contributed to 13.6% of all crashes. The major distracting activities were talking with passengers, lack of concentration, and outside factors.
However, the study also found the danger associated with the presence of passengers is still not as dangerous as talking on a cell-phone while driving.
