The U.S. National Highway Traffic Safety Administration’s National Center for Statistics and Analysis has released a Traffic Safety Facts Research Note that examines restraint use patterns among fatally injured passenger vehicle occupants. According to the research note, in 2004, the majority (55%) of the occupants of passenger vehicles (passenger cars, light trucks, vans, and sport utility vehicles) killed in motor vehicle crashes were unrestrained. When examined more closely, the data show that the proportion of unrestrained fatalities was higher among males, on rural roadways, in pickup trucks and sport utility vehicles, in single-vehicle crashes, and in the age group of 8 to 44 years old.
