The official book the Louisiana motorcycle knowledge test is based on — where to get it and how to study it.
The Louisiana Office of Motor Vehicles publishes the current motorcycle manual on its official site. Always study the latest edition.
Every question on the Louisiana 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 Louisiana Office of Motor Vehicles, 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.
