The official book the South Dakota motorcycle knowledge test is based on — where to get it and how to study it.
The South Dakota Department of Public Safety, Driver Licensing Program publishes the current motorcycle manual on its official site. Always study the latest edition.
Every question on the South Dakota motorcycle knowledge test is drawn from the official motorcycle operator manual — a different book from the regular car driver handbook. Always study the most recent edition published by the South Dakota Department of Public Safety, Driver Licensing Program, because rules and numbers change between revisions.
Read one chapter at a time, then test that chapter with the practice test before moving on. Pay extra attention to chapters on gear, the pre-ride inspection, hazard awareness (SEE), and emergency maneuvers — these are the most heavily tested sections. Score 20 of 25 correct (80%) to pass.
Source: Some test details are confirmed by the state agency; the rest reflect the consensus of major rider-education sources. dps.sd.gov states the written test must be passed at 80% or higher; the 25-question count is the third-party consensus. The manual is the standardized MSF Motorcycle Operator Manual, 18th Edition (June 2020), with a South Dakota DPS front section (Revised October 2020).
