Over the years, driving under the influence of alcohol has been perceived to be the leading cause of car accidents resulting in tens of thousands of injuries and millions upon millions spent on accident settlements. According to the National Highway Traffic Safety Administration (NHTSA), a Blood Alcohol Content (BAC) of .05 which is considered legal, increases a driver’s chances of causing an accident by 100%, which is higher than that of a sober driver. However, the issue of road safety can not be entirely dealt with without reviewing other factors that contribute to the increase in the number of car accidents. As unlikely as it might seem, driving under the influence of sleep can significantly increase the likelihood of causing an accident.
A report drafted by the Automobile Association of America (AAA) indicates that drivers who have 6-7 hours of sleep before driving are 30% more likely to cause an accident compared to those who have 7-plus hours of sleep. What’s more shocking is that as sleep time decreases, the likelihood of causing an accident increases significantly as shown below.
