GAO examined a nongeneralizable sample of 178 polling places during early in-person voting and on Election Day 2016. At these polling places, GAO examined a number of features outside and inside the voting area. Outside the voting area, GAO was able to examine features at all 178 polling places and found that 60 percent had one or more potential impediments. The most common were steep ramps located outside buildings, lack of signs indicating accessible paths, and poor parking or path surfaces.
