Vehicles entering a driveway from an exclusive right-turn lane may restrict the sight distance available to vehicles waiting to enter the arterial street from the driveway. The sight distance available to the vehicles waiting at a driveway is a function of the geometric design of the driveway and the right-turn lane. The relationship between available sight distance and the relevant geometric design variables is examined. The analysis identifies geometries that provide adequate sight distances for various design speeds.
