Free South Dakota CDL Practice Tests 2024

While South Dakota is sparsely populated, the state boasts a mature trucking industry supported by associations like the South Dakota Trucking Association. The most common route for drivers is through the I-29 corridor, which runs through the eastern part of the state from the Iowa border near Sioux City to the North Dakota border near New Effington. This route takes you through Sioux Falls, the state’s largest city.
