Roadside survey on alcohol and drug use among drivers in the Arctic county of Finnmark (Norway).
The objective of this study was to determine the prevalence of alcohol and potentially impairing drugs among the general driving population in Finnmark and to compare the prevalence among Norwegian, Russian, and other foreign drivers by analyzing samples of oral fluid. ⋯ The total prevalence of alcohol and drugs among the general driving population in Finnmark was low and similar to previous Norwegian roadside surveys. Illicit drugs were detected significantly more often in samples from drivers with citizenship other than Russian and Norwegian and among young male drivers.

ReviewRoad accident fatality risks for "vulnerable" versus "protected" road users in northern Ghana.
Road traffic injuries (RTIs) are a serious epidemic that claims more than a million lives across the globe each year. The burden of RTIs is particularly pronounced in Africa and other low- and middle-income countries. The unfavorable disparity of the burden of road trauma in the world is largely attributable to unsafe vehicles, lack of appropriate road infrastructure, and the predominance of vulnerable road users (VRUs) in developing countries. However, little research exists in northern Ghana to highlight the scale and risk of death among road users. ⋯ Provision of requisite road infrastructure is vital for the safety of VRUs in northern Ghana. Cycle paths and lanes (for cyclists) as well as sidewalks (for pedestrians) in particular will separate VRUs from motorists and improve their safety. Enforcement of traffic laws particularly regarding helmet use, speeding, and alcohol use will be beneficial. Introduction of the demerit points system in the enforcement of traffic regulations may have significant deterrent effects on road users who have the penchant for violating traffic regulations. Road safety education is also required to create responsible road users.

Effects of speed-control measures on the safety of unsignalized midblock street crossings in China.
The primary objective of this study was to evaluate the effects of different speed-control measures on the safety of unsignalized midblock street crossings. ⋯ Consequently, in order to reduce vehicle speeds and improve pedestrian safety at mid blocks, several speed-control measures such as speed humps, speed bumps, and transverse rumble strips are recommended to be deployed in the vicinity of pedestrian crosswalks.

This is a descriptive study of the frequency and risk for brainstem injury by crash type, belt use, and crash severity (delta-V). NASS-CDS electronic cases were reviewed to see whether the transition from vehicles without advanced airbags and seat belts and side airbags and curtains to vehicles with the safety technologies has influenced the risk for brainstem injury. ⋯ The risk for brainstem injury in belted occupants has remained essentially constant over 20 years, whereas the risk for MAIS 4+F injury has declined 38.3%. The prevention of brainstem injuries must address the extreme speed of collisions and weight mismatches that overwhelm structures, seat belts, frontal airbags, side airbags, and curtains in modern vehicles.
