Motorized Vehicle Safety

Restraint devices such as seat belts are a key element of motor vehicle occupant protection systems. Each year, the National Highway Traffic Safety Administration (NHTSA) conducts the National Occupant Protection Use Survey (NOPUS) that measures, among many variables, the use of seat belts by occupants age eight and older. The 2019 NOPUS reported that seat belt use was 90.7 percent among front-seat passengers, a slight increase from the 89.6 percent observed in 2018. Additionally, the 2019 survey found that seat belt use increased during both weekday rush hours and non-rush hours. Use...

Collisions involving motorcycles are a major traffic safety concern in the United States. Motorcycle riders comprise a disproportionate share of all injured and killed vehicle occupants. In 2016, motorcycle riders were 28 times more likely than passenger car occupants to be fatally injured in a traffic collision, per vehicle miles traveled. The primary countermeasures used to address this problem have included motorcycle helmet laws and other helmet-oriented programs, rider training and licensing programs, vehicle enhancements, including anti-lock braking technology, rider conspicuity...

A significant proportion of fatalities from motor vehicle collisions (MVC) could be prevented through better emergency medical service (EMS) care. Despite a lack of conclusive research, there is a consensus that prehospital time (the time between the MVC and the patient’s arrival at the hospital) must be reduced as much as possible. Many studies use response time (the time between EMS dispatch and arrival at the scene) as an indicator of overall prehospital time and a metric of EMS performance. However, there are other components of prehospital time that may be equally important, including...
