What's the Passing Score on the Louisiana Permit Test?
You need 32 of 40 questions correct — 80% — to pass Louisiana's learner's permit knowledge test.
The math behind 80% on a 40-question test
32 correct out of 40 leaves room for 8 wrong answers, a bit more numeric margin than some states' shorter tests, though the underlying 80% standard is common nationally.
That margin doesn't excuse skipping preparation — a driver who guesses through several topics can still fail even with 8 misses to spare.
Building in a safety margin
Treat 80% as a floor, not a target — aim for 90%+ across all topic areas in practice, since real testing conditions 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.
What tends to trip people up
Louisiana's supervision rules are more detailed than most states' — a licensed sibling at least 18 can supervise a permit holder, alongside the more familiar parent/guardian/21+ adult option, and it's easy to forget that alternative.
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.
