There's a new concern about obesity. Obese drivers are much more likely to die in car crashes than normal weight people. The study is published in the current Emergency Medicine journal. It's based on 12 years of fatalities recorded by the National Highway Traffic Safety Administration, which showed 57,000 collisions, in which one or both drivers died. The study found that obese drivers face a greater risk of death in a traffic accident because they are thrown further on impact before the seatbelt tightens. The theory is additional fat prevents the belt from tightening when it should. The study suggests with more and more people overweight, we may need some changes in car design.
