This study evaluated the traffic-safety impact of the California Department of Motor Vehicles' Commercial Driver License (CDL) program. The program, initiated on 1 January 1989, began a new commercial-license classification and endorsement system, implemented stronger licensing standards and more comprehensive tests of knowledge and driving competency, required drivers to report specific violat...

OBJECTIVES The purpose of this study was to evaluate the rate of, and risk factors for, subsequent impaired driving activity (IDA) in a cohort of injured passengers who were treated for injuries in a Canadian trauma center. METHODS We studied adult passengers who were occupants in vehicles involved in motor vehicle crashes (MVCs) and either included in the British Columbia (BC) trauma registr...

PROBLEM Given the public safety risk posed by violation and crash repeaters and the substantial costs for state driver improvement programs, it is important that their effectiveness be scientifically demonstrated and that intervention programs are based on sound research findings. METHOD Crash and traffic violation standardized effect sizes (d) representing 106 individual interventions were c...

In this paper we describe a small electric vehicle equipped with automatisms that allow autonomous motion. A eet of such vehicles could be one element of a novel urban transportation system to door-to-door displacement in closed area (city centers but also touristic resorts, campuses, ...) if they are used in self-service and car-sharing mode. The speciications in the matter of performances (ra...

Objective. To determine the influence of deep brain stimulation (DBS) on daily routine driving behavior in Parkinson's disease (PD) patients. Methods. A cross-sectional questionnaire survey was done in 121 DBS-PD patients. The influences of patient characteristics and DBS on current driving and driving at time of surgery and the predictive value of the preoperative levodopa-test on postoperativ...

Studies have shown that the effect of passengers on accident propensity among young drivers is ambiguous—in some cases positive and some negative. In Sweden, various kinds of information are compiled in registers, including a national accident database and exposure data collected in a national investigation of the driving habits of license holders. Access to such data offers a good opportunity ...

epilepsy is one of the most prevalent serious neurologic conditions, affect 1 % of the population worldwide. people with epilepsy may feel it's safe to drive when their seizures seem to be under control, but patients with epilepsy were seven times more likely to have a driving accident leading to emergency room care than those without epilepsy. people with seizures had 2.3 times the rate o...

The new Brazilian Traffic Code considers drinking and driving as a traffic crime. A health behavior model suggests that much of the young people’s risky behavior is not planned and that questions measuring the willingness to drink and drive are useful. In face of the importance of drinking and driving as a national health problem, the objective of the present study was to analyze the behavior w...

conclusions the result of this study did not find an independent association between adhd and helmet use. results univariable analysis showed the mean of the age variable was significantly higher in the helmeted group, 26.94 ± 7.72 vs. 23.08 ± 7.7.32, (p < 0.001). the majority of the non-helmeted group was single (p < 0.001). subjects with secondary educational level were more often in the helm...
