OBJECTIVE To investigate differences in the incidence of motor vehicle crashes (MVCs) and violations among drivers with multiple sclerosis (MS) when cognitive impairment is present. DESIGN Archival evaluation of Department of Motor Vehicles (DMV) records. SETTING Medical rehabilitation research organization. PARTICIPANTS Community-dwelling drivers, 27 subjects with documented MS (14 MS wi...

Case reports of 16 crashes involving pregnant occupants are presented that illustrate the main conclusions of a crash-investigation program that includes 42 crashes investigated to date. Some unusual cases that are exceptions to the overall trends are also described. The study indicates a strong association between adverse fetal outcome and both crash severity and maternal injury. Proper restra...

Click It or Ticket is a national campaign coordinated annually by the National Highway Traffic Safety Administration to increase the proper use of seat belts. In 2014, more than 21,000 passenger vehicle occupants died in motor vehicle crashes in the United States; 49% were unrestrained at the time of the crash (1). An additional 2.4 million occupants (restrained and unrestrained) were treated i...

The transportation system has a number of adverse environmental impacts. The effects can be direct, indirect and both. Indirect effects may have greater consequences than direct effects, but are not generally well known. Transportation system and the operation of vehicles can affect rural and urban community. Emission and road crashes have a significant impact on health, and the form of the tra...

Melissa M. Amick, PhD  the number of drivers over the age of 75 will dramatically increase over the next few decades. Adults age 85 and older have the highest rate of driver fatalities. Individuals age 70 and older have the greatest motor vehicle fatality rates per mile driven compared to all but the riskiest age group, those 25 years and younger. Advanced age is also a risk factor for motor v...

Dilemma Zone Design as a Marginal Cost-Benefit Problem" (2007). One control objective at high-speed isolated intersections is to provide safe phase transition by minimizing the occurrence of high-speed vehicles in the dilemma zone before the phase is terminated. An upper limit for extending the green (maximum green time) is used to avoid an indefinite extension of the main-street green. Current...

Driving under the influence of cannabis is an important public safety concern. Drug impaired driving endangers those both inside and outside the driver’s vehicle. Smoking, inhaling or eating cannabis with or without alcohol prior to driving is a common practice and increases the risks of driver impairment, motor vehicle crashes and fatalities. There are also new techniques for administering hig...

BACKGROUND In the United States, major compression and burst type fractures (>20% height loss) of the lumbar spine occur as a result of motor vehicle crashes, despite the improvements in restraint technologies. Lumbar burst fractures typically require an axial compressive load and have been known to occur during a non-horizontal crash event that involve high vertical components of loading. Rece...
