How Many Questions Are on the Idaho Motorcycle Permit Test?
Idaho's motorcycle knowledge test has 25 questions, requiring 20 correct (80%) to pass — a more forgiving threshold than the state's own 85% car permit test.
What the test covers
The 25 questions are drawn from the Idaho Motorcycle Operator Manual, covering topics like protective gear, braking technique, cornering, and sharing the road with other vehicles.
The motorcycle permit itself costs $5, separate from any car permit or license fee.
A required course for the youngest applicants
An applicant under 21 must complete a Motorcycle Safety Foundation (MSF) course before earning an endorsement, in addition to passing the knowledge and skills tests.
Knowledge and skills test results stay valid for up to one year, giving an applicant real flexibility in scheduling the remaining steps.

dmvwrittenexam.com's Idaho motorcycle bank covers both nationally-consistent riding fundamentals and Idaho-specific rules like its under-18 helmet requirement.
Each question includes an explanation and a source reference, so you learn why an answer is correct instead of just memorizing a letter.
