Women judging: is a young male drunk driver perceived as more negligent than a young female drunk driver?

Objective: It is well established that young men are the riskiest group of all drivers, and men in general more often drive under the influence of alcohol. However, potentially oversimplified representations such as a young male problem and drunk driving as a male problem can influence action and reinforce existing attitudes by selectively directing attention to stereotypically consistent behavior. The purpose of this study was to test the hypothesis of possible bias toward young male drivers in the context of drunk driving.Methods: We have created a scenario study investigating whether the sex of an imaginary young drunk driver would be associated with a different perceived negligence (ranging from 0=not negligent at all to 10=extremely negligent) among our participants. These participants were a representative sample of Finnish female driver's license holders. The data for the study were gathered as part of a larger survey study on women's drinking and driving culture.Results: Perceptions of how negligent a person was depended on the age of the respondents such that the older the respondent, the higher the perceived negligence. Perceived negligence was similar for male and female drivers in the scenario; however, there was an interaction effect between driver sex and the age of respondents. The youngest (20-29 years) and 2 oldest (50-69 years) groups of our respondents found the young woman to be more negligent, whereas the opposite occurred for the other 2 groups.Conclusions: The results of our imaginary scenario study of a representative sample of Finnish female driver's license holders do not support a hypothesis that there would be a negative bias toward young male drivers in the context of drunk driving behavior.Peer reviewe

Suicide by crashing into a heavy vehicle: Professional drivers’ views

Objective: Every profession has its own safety and health risks. In addition to the risk of being involved in a "normal" road crash, professional heavy vehicle drivers are at risk of becoming victims of people attempting suicide by crashing into their vehicles. Road suicides are not that rare, at least not in Finland, where they represent about 12% of all fatal road crashes. The purpose of this study was to survey professional heavy vehicle drivers about their experiences, views and opinions regarding road suicides. Methods: The sample included heavy vehicle drivers (N = 863) randomly recruited from a transport workers' union. Results: About 18% of the respondents reported a suspected suicide attempt of a motor vehicle driver crashing into their vehicle, with 15% of these (i.e.2.8% of the whole sample) also reporting a resulting crash. More than half of the respondents reported personally knowing another professional driver who had experienced a crash caused by a suicidal driver. Almost 80% of the drivers reported being afraid that someone would attempt suicide by crashing into their vehicle; however, thinking about such a possibility produces a level of anxiety in less than half of all respondents. Most respondents agreed about the challenges of avoiding a crash if somebody deliberately drives their car towards their vehicle. Conclusion: Heavy vehicle drivers perceive road suicides as an occupational risk in their profession. We discuss possible preventive measures against suicide attempts by crashing into a heavy vehicle.Peer reviewe

Suicide by crashing into a heavy vehicle : A one-year follow-up study of professional drivers

Train and heavy vehicle drivers can experience a traumatic event caused by people attempting suicide by crashing into their vehicles or jumping in front of them. While there are a number of studies on train drivers showing the negative consequences these events can have on their well-being, there are no studies on heavy vehicle drivers involved in these types of crashes. In the current study, we surveyed Finnish heavy vehicle drivers(N = 15) involved in a suicide crash in the year 2017 regarding their experiences and coping approximately one month (T1) and one year (T2) after the crash. Ten of these drivers reported one or various combinations of measurable consequences such as minor physical injuries, shorter or longer sickness absences, significant posttraumatic stress symptoms(measured using the Impact of Events Scale-Revised) and requiring psychological help. Posttraumatic stress symptoms decreased over time; however, three out of the four drivers who had a high IES-R score at T1 were still around the IES-R cut-off score at T2. This research raises questions whether and what kind of support heavy vehicle drivers who have been involved in a suicide crash should be givenPeer reviewe

Endangering yourself to save another : A real life ethical dilemma

Unlike hypothetical trolley problem studies and an ongoing ethical dilemma with autonomous vehicles, road users can face similar ethical dilemmas in real life. Swerving a heavy vehicle towards the road-side in order to avoid a head-on crash with a much lighter passenger car is often the only option available which could save lives. However, running off-road increases the probability of a roll-over and endangers the life of the heavy vehicle driver. We have created an experimental survey study in which heavy vehicle drivers randomly received one of two possible scenarios. We found that respondents were more likely to report they would ditch their vehicle in order to save the hypothetical driver who fell asleep than to save the driver who deliberately diverted their car towards the participant's heavy vehicle. Additionally, the higher the empathy score, the higher the probability of ditching a vehicle. Implications for autonomous vehicle programming are discussed. (C) 2019 Elsevier Ltd.

Suicide by crashing into a heavy vehicle: Focus on professional drivers using in-depth crash data

Objective: Road traffic suicides typically involve a passenger car driver crashing his or her vehicle into a heavy vehicle, because death is almost certain due to the large mass difference between these vehicles. For the same reason, heavy-vehicle drivers typically suffer minor injuries, if any, and have thus received little attention in the research literature. In this study, we focused on heavy-vehicle drivers who were involved as the second party in road suicides in Finland. Methods: We analyzed 138 road suicides (2011-2016) involving a passenger car crashing into a heavy vehicle. We used in-depth road crash investigation data from the Finnish Crash Data Institute. Results: The results showed that all but 2 crashes were head-on collisions. Almost 30% of truck drivers were injured, but only a few suffered serious injuries. More than a quarter reported sick leave following their crash. Injury insurance compensation to heavy-vehicle drivers was just above euro9,000 on average. Material damage to heavy vehicles was significant, with average insurance compensation paid being euro70,500. Three out of 4 truck drivers reported that drivers committing suicide acted abruptly and left them little opportunity for preventive action. Conclusions: Suicides by crashing into heavy vehicles can have an impact on drivers' well-being; however, it is difficult to see how heavy-vehicle drivers could avoid a suicide attempt involving their vehicle.Peer reviewe
