The official book the New Mexico motorcycle knowledge test is based on — where to get it and how to study it.
The New Mexico Motor Vehicle Division publishes the current motorcycle manual on its official site. Always study the latest edition.
Every question on the New Mexico 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 New Mexico Motor Vehicle Division, 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 18 of 25 correct (70%) to pass.
Source: Some test details are confirmed by the state agency; the rest reflect the consensus of major rider-education sources. The official page states Class D and M tests must score 70%+ — the only state below 75%. The question count is an estimate (70% of 25 ≈ 18).
