What's the Passing Score on the Missouri Motorcycle Permit Test?
You need 20 of 25 questions correct — 80% — to pass Missouri's Class M motorcycle knowledge test, the same threshold used for the state's regular permit written test.
The same 80% standard, different material
Missouri doesn't set a higher bar for motorcycle applicants the way some states do — the 80% threshold matches the regular Class F written test.
What differs is the subject matter: braking technique, cornering, protective gear, and motorcycle-specific hazards replace the car-focused content of the regular test.
Building in a safety margin
Treat 80% as a floor, not a target — aim for 90%+ across every topic area in practice, since real testing conditions under time pressure tend to run a few points below your practice average.
Our practice tests break your score down by topic immediately after each set, so a weak spot doesn't stay hidden inside an otherwise decent overall percentage.
The parts of the test that pull scores down
Countersteering and threshold-braking questions trip up riders who've never had them explained in plain language, since both work differently than car intuition suggests.
Missouri's age-and-insurance-conditioned helmet rule is also a common miss — remembering exactly who's exempt (riders 26 and older with qualifying insurance) rather than assuming an age cutoff alone applies.
Read the explanation on every practice question, correct or not — it's what actually closes these gaps, not just re-answering until you get lucky.
Frequently Asked Questions
Is Missouri's motorcycle test passing score higher than the car permit test?
No — both require 80%. Missouri doesn't set a stricter threshold for motorcycle applicants.
How many of the 25 motorcycle questions can I miss and still pass?
At most 5, keeping you at 20 correct (80%).
What score should I aim for on practice tests?
Aim for 90% or higher consistently before your appointment. That buffer above the 80% minimum accounts for first-attempt nerves.
