“…One possible explanation for this result is that the concentration, cognitive ability, and reaction time required for safe driving begin to decrease in truck drivers as they age, making them more likely to be involved in wrecks. However, sex difference was not found to have an influence on the chance of being involved in injury and fatality crashes, which is in accordance with our previous finding [3] and in discordance with the results of other studies [24,25]. This may be due to the very low proportion of female truck drivers (6.30% of the total sample).…”

The occurrence and severity of truck crashes generally involve complex interactions among factors correlated to driver characteristics, vehicle attributes, roadway geometry and environment conditions. Thus, the elucidation of the significance of these potential contributory factors is critical when developing safety improvement countermeasures. To this end, data from a total of 1175 crashes involving at least one large truck and collected between 2010 and 2015 from two typical freeways in mountainous areas in Jiangxi and Shaanxi (China), were analyzed using a partial proportional odds model to determine the significant risk factors for injury severity of these crashes. Fourteen total explanatory variables, including the age of the driver, seatbelt status, number of vehicle involved, type of transport, freight conditions, brake system status, disregarding speed limit or not, following distance, horizontal roadway alignment, vertical roadway alignment, seasons, day of week, time of crash, and weather were found to significantly affect the severities of the truck crashes. In addition, old drivers, involvement of multiple vehicles, failure to wear seatbelts, overloading, speeding, brake failure and risky following behavior, curve section, seasons (summer, autumn and winter), nighttime period, and adverse weather conditions were also found to significantly increase the likelihood of injury and fatality crashes. Taken together, these findings may serve as a useful guide for developing legislation and technical countermeasures to ensure truck safety on freeways in mountainous regions, particularly in the context of a developing country.

“…According to police evaluations, nearly one half of women compared to one‐fifth of men with PD involved in FMVAs were thought to have suicidal intent . A previous study has established that driver suicides represent a small proportion (2%) of all suicides committed in Finland each year. However, according to their findings, the proportion of driver suicides of all FMVAs is greater (8–9%).…”

Objective: To examine the association of personality disorders (PDs) to deaths of drivers in fatal motor vehicle accidents (FMVAs) and analyze gender differences in lifetime psychiatric disorders and medico-legal findings at the time of accident. Method: The study sample consisted of 4810 Finnish drivers killed in FMVAs in Finland between 1990 and 2011. Doctor-diagnosed PD was found in 146 drivers (118 men and 28 women). The information of psychiatric morbidity was obtained from the Finnish Care Register for Health Care. Results: The proportion of deceased drivers with PDs had increased significantly over the study period, particularly among females and those with PD not otherwise specified (NOS). Suicidality and use of medication affecting driving ability were more common among females with PD compared to males with PD. 88% of all deceased drivers with PD had comorbid psychiatric disorders. Conclusion: Our findings indicate that PDs may predispose drivers to FMVAs, particularly females. This study emphasizes the importance of evaluating the fitness-to-drive of subjects with PD and especially comorbid substance use disorders, which may relate to an increased risk of fatal motor accidents. Significant outcomes• In Finland, the proportion of deceased drivers with hospital-treated personality disorders (PDs) has significantly increased during the years 1990 to 2011.• The increase was emphasized in female drivers with PD. • Suicidality and medication use were more common among female drivers with PD. Limitations• Personality disorders (PDs) are underestimated in register-based data.• This study lacks of alive control population with PD.

“…However, most confirmed road suicides are collisions with another, typically heavy, vehicle (Björnstig et al 2008;Hernetkoski et al 1998;Gauthier et al 2015;Sassi et al 2018). The occupants of the other vehicle, if they survive, as heavy vehicle drivers normally do, can provide valuable information for investigation processes into the actions of the car driver just before the crash.…”

Objective: Road traffic suicides typically involve a passenger car driver crashing their vehicle into a heavy vehicle, as 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 the in-depth road crash investigation data from the Finnish Crash Data Institute. Results: The results showed that all but two 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 9000€ on average. Material damage to heavy vehicles was significant, with average insurance compensation paid being 70 500€. Three out of four 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.

Abstract: The findings give support to the recommendation that suicidal ideation must be considered when assessing fitness-to-drive.
