Drivers’ Beliefs,Habits,and Strategies Regarding High Beam Usage

Abstract

Research suggests that drivers do not fully understand the visual challenges they face when driving at night, and that drivers typically under-use their high beams. Because little is known about what factors influence drivers’ usage of high beams, this study surveyed 202 undergraduates concerning their beliefs, habits, and strategies in choosing beam settings. Participants completed a 29-question survey asking about their general understanding of headlamp usage and roadway safety. These data reflect what drivers learned about beam usage when they were taught to drive and describe the factors that influence drivers’ selection of high and low beams. The data also describe the participants’ estimates of the frequency with which they use high beams, and quantify drivers’ estimates of the distance at which they can see different objects at night. These data offer insight into drivers’ beliefs about headlights, night vision, and safety. These insights are expected to be useful when designing educational interventions to encourage appropriate usage of high beams.
