Development and validation of questionnaires on professional drivers’ knowledge and attitudes about various medications’ influence on driving ability

Introduction Professional drivers’ knowledge about driving-impairing medications is not satisfactory. The aim of this study was to develop and test the reliability and validity of the questionnaires designed to measure the knowledge and attitude of professional drivers about the influence of various medications on driving ability. Methods The questionnaires for assessing professional driver’s knowledge (performance-based) and attitudes about influence of various medications on driving abilities were developed by creating the item pool, testing reliability and validity, and factor analysis. The study was conducted as a multicenter, cross-sectional study in Serbia and Bosnia and Herzegovina. The study population consisted of professional drivers, who filled out both questionnaires in three time intervals. Results Both questionnaires showed great internal consistency and temporal stability. Cronbach’s Alpha for the first questionnaire was 0.984 and for the second it was 0.944. The Kaiser–Meyer–Olkin test for the first questionnaire confirmed sampling adequacy with its value of 0.964 and for the second questionnaire it was 0.933. Exploratory factor analysis of the questionnaire showed that three factors were revealed after rotation for the first questionnaire and they explained 78.0% of variance. Both questionnaires showed high degree of correlation between scores after the first and repeated administration, Spearman’s rho coefficient of correlation for was 0.962 and 0.980. Conclusion Based on the results of this study, we believe that both questionnaires are useful tools for testing professional drivers’ knowledge and attitudes about the influence of medications on driving ability.

Consumption, risk factors, and the impact of psychoactive substances in road transport by professional drivers: a review

Traffic accidents are a serious public health problem, especially in developing countries. Driving under the influence of psychoactive substances, such as illicit drugs, can significantly increase the risk of motor vehicle accidents. This fact potentiates the probability of serious traffic accidents occurring, making it necessary to combat them with seriousness and urgency. Many road traffic crashes are related to sleepiness and/or fatigue. In addition to long driving hours, important contributors to fatigue among professional drivers are insufficient night-time sleep and insufficient rest breaks. Research data on the topic show that several psychoactive drugs alter the motor and cognitive capacity of users, however, most of these studies pointed out such outcomes based on the prevalence of illicit drug use in professional hospitalized drivers. Despite the existence of laws against driving doped, the effectiveness of these laws in controlling the problem is questionable. For this research, the study was conducted to highlight and discuss, by a descriptive review, the consumption of psychoactive substances among professional drivers, and the role of working conditions in the prediction of such use. Data about drug use were obtained in this review aims to contribute for the development of preventive measures, especially public policies on the risks of driving while under the influence of psychoactive drugs.

Driver behaviour and traffic accident involvement among professional heavy semi-trailer truck drivers in China

The purpose of this study was to develop a driving behavior scale for professional drivers of heavy semi-trailer trucks in China, and study the causes of such driving behavior and its impact on traffic safety operation. Data was processed by IBM SPSS 25. In addition to principal component analysis, Promax rotation, Bartlett’s test, Cronbach’s alpha, correlation analysis and binary logistic regression were examined. A DBQ with 4 dimensions and 20 items, and a PDBQ with 1 dimension and 6 items were developed for professional drivers of heavy semi-trailer trucks in China. The KMO coefficients of PDBQ and DBQ were 0.822 and 0.852, respectively, and the significant level of Bartlett’s popularity test was p < 0.0001. The accident prediction model showed that the variables related to traffic accidents were negligence/lapses and driving time of heavy semi-trailer truck drivers. 1–5 a.m. was found to be the most dangerous period for drivers of medium and heavy semi-trailer trucks, during which accidents were most likely to happen. As negligence/lapses increased by one unit, the probability of traffic accidents increased by 2.293 times.

A Road Safety-Based Selection Methodology for Professional Drivers: Behaviour and Accident Rate Analysis

In this paper, we examine the factors affecting the behaviour of road users and the impact of these factors on professional drivers’ reliability and performance. A professional driver is considered as a driver involved in the processes of driving a vehicle as a matter of his/her business or the transportation of passengers or goods by bus or lorry, with higher liability in terms of road safety and requiring a higher degree of maintained attentiveness, constant concentration, and working capacity. This article highlights the process of selecting a professional driver by focusing on the driver’s individual and psychophysiological characteristics. An anonymous survey on professional drivers and a statistical analysis of the accidents caused by professional drivers was used to research the impact of fatigue on the behaviour of road users. The conducted statistical analysis demonstrates that the amount of professional driving experience most conducive to driving a vehicle safely was observed at between 29 and 33 years of experience. It was also found that a higher probability of causing an accident after rest days is related to the driver’s long period of engagement at work and inadequate rest. This study demonstrates that specific requirements should be applied to the methodologies for selecting professional drivers, the research on the reliability of which aims to develop a concept that enables opting for those drivers able to properly perform hired work, causing minimal losses due to road accidents.

Lifestyle Medicine Strategies for Combating Sleepiness and Fatigue in Professional Drivers - The "Highway 2 Health" study

Sleep has a number of health benefits, including memory and learning, vitality and energy as well as high quality of life levels. Lack of sleep impairs judgment, impacts longevity and safety, and increases the risk of a number of diseases including obesity, hypertension, heart disease, diabetes, mood disorders, and impaired immune function. In addition lack of sleep or disturbance of normal sleep cycle could have a major impact on people's lives and working performance such as driving. Daily sleepiness is a problem concerning professions with a non-fixed schedule. Specifically, professional long-haul drivers confront sleepiness problems and in combination with fatigue, they are prone to driving accidents and other incidents. Sleep quality and quantity are closed related to fatigue which is one of the most common reasons for driving and working accidents. In recent years, car accidents involving professional drives have increased significantly. The main reasons for those accidents were fatigue and sleepiness due to long hours of driving or difficult working conditions according to the recent European report (Driver Fatigue in European Road Transport - etf-europe.org).Lifestyle Medicine addresses health risk factors in primary, secondary, and tertiary prevention of developing disease rather than on acute care and reacting to illness, injury, and disease. Lifestyle Medicine strategies target modifiable risk factors, such as diet, sleep, stress, and physical activity. By applying those regimes the investigators could improve physical and mental health levels that can affect the quality of sleep, reducing daily sleepiness and fatigue, in professional drivers operating coaches and trucks. Any intervention that could improve alertness and reduce fatigue and sleepiness in those people, will automatically improve safety, reduce driving accidents and save lives and resources.The study is registered on the ClinicalTrials.gov public website (NCT05096130).

A GROUP OF PROFESSIONAL DRIVERS IN TRAFFIC: ATTITUDES OF MALE BUS DRIVERS TOWARDS TRAFFIC ACCIDENTS

Traffic accidents are among the leading causes of injury-related fatalities among the world. Considering driver-oriented studies, there are limited number of research in the literature about the general causes of traffic accidents involving professional drivers. In the current study, professional drivers' attitudes towards traffic accidents and the causes of accidents were examined. Semi-structured interviews were conducted with 20 bus drivers. The findings were categorized under seven themes: Evaluations of Accidents, Gender Differences, Positive Attitudes towards Colleagues, Violations, Age, Organizational Factors, External Factors. The results of the study indicate that the bus drivers, who are a subgrop of professional drivers, evaluate themselves more positively regarding their driving skills and see the responsible person as the opposite party in traffic accidents. In addition, if the other party involved in the accident was a female driver, even they attribute the responsibility to female drivers, they generally tried to be more tolerant. The results were discussed based on individual, organizational, national and socio-political levels. In order to see that there are many factors that play a role in traffic accidents, it has been a strong study that contributes to the field. In line with these findings, developing trainings for professional drivers about traffic accidents and factors that may cause traffic accidents might make people more conscious.
