BACKGROUND All-terrain vehicle (ATV) injury is a serious problem in children and adolescents. We report an unusual case of a child with cranial impalement in a rollover ATV crash. CASE An 8-year-old, reportedly helmeted, was driving an ATV uphill when it rolled over causing cranial impalement of the brake handle just above the left ear. The child was awake and alert at the scene and on arriva...

The electronic stability program (ESP) is increasingly finding acceptance in vans and light commercial vehicles (LCV). Nearly all current models, whose gross vehicle weight is generally between 2.8 and 7.5 metric tons, are now available with this active safety system, either as an option or even as standard equipment. Many studies have now confirmed that ESP can prevent a vehicle from skidding ...

The risk of fatal rollover of utility vehicles per 100,000 registered vehicles relative to cars during 1982-87 was strongly correlated to the static stability of the vehicles. Distance between the center of the tires divided by twice the height of center of gravity explained 62 per cent of the variation in fatal rollover rates where rollover was the first harmful event. Statistical controls for...

Simulation is often used to gain an understanding of vehicle directional response. Furthermore, it is widely agreed that, given an adequate set of parameters that model the vehicle and the surface it drives on, it is reasonable to simulate a particular vehicle with a view toward understanding and perhaps improving its performance. This is not the case with the vehicle/driver system. Rather, in ...

This study investigated the effects of shoe heel height on the rollover characteristics of the biologic ankle-foot system. Ten nondisabled adult female volunteers walked using three pairs of shoes with varying heel heights and at three walking speeds with each pair of shoes. Kinematic and kinetic data needed to calculate the rollover shapes of the ankle-foot systems of the participants were col...

Subject review Crash detection sensors play a vital role in vehicular safety applications. One of the major applications of these sensing systems is the use in occupant restraint systems. Besides, sensors are extensively used in the accident mitigation and advanced vehicle control system. Crash sensors have advanced significantly in the last few decades. Yet, existing demands and challenges bri...

Motor vehicle crashes are the second leading cause of death for on-duty firefighters. Firetruck crashes, occurring at a rate of approximately 30,000 crashes per year, have potentially dire consequences for the vehicle occupants and for the community if the firetruck was traveling to provide emergency services. Data from the United States Fire Administration and the National Highway Traffic Safe...

This paper is an empirical investigation of the asset pricing implication of rollover risk, the risk that a firm might not be able to refinance its due liabilities. I focus on the long-term debt rollover risk and use the proportion of long-term debt falling due within the year to measure a firm’s exposure to rollover risk. I find that firm-specific rollover risk coupled with deteriorating marke...

The lateral security of heavy vehicle in deteriorative weather is one of the main causes of accidents of vehicles on roads. Road safety has become a subject of great concern to institutions of higher education and scientific research institutions. There are important theoretical and practical significances to explore applicable and effective lateral safety warning methods of heavy vehicles. One...

Vehicles with a high center of gravity (COG), such as light trucks and heavy vehicles, are prone to rollover. This kind of accident causes nearly 33 % of all deaths from passenger vehicle crashes. Nowadays, these vehicles are incorporating roll stability control (RSC) systems to improve their safety. Most of the RSC systems require the vehicle roll angle as a known input variable to predict the...
