South Dakota state gas tax: 30¢/gal · Federal tax: 18.4¢/gal · Total tax: ~48¢/gal
South Dakota has moderate prices reflecting its central location with decent but not excellent pipeline access. Sioux Falls is well-supplied; western SD near Rapid City and the Black Hills is more expensive due to truck delivery distance. Tourist traffic in summer drives prices up near Mount Rushmore.
