Fatigue is a major risk factor in commercial motor vehicle operations, identified in naturalistic driving studies as a contributing factor in approximately 20 percent of safety-critical incidents. Understanding the nature of fatigued driving requires attention to several elements of the driving situation, including driver characteristics. The purpose of the present report is to explore driver body mass index (BMI) as a characteristic which may put one at increased risk for driving while fatigued.
