DMV Passing Score by State (All 50 + DC)

The national picture: 80% is the standard

Across all 51 jurisdictions, 80% is by far the most common passing bar — roughly 71% of states use it. That's no coincidence: the federal FMCSA mandates 80% for every CDL knowledge test nationwide, and most states aligned their regular driver test to the same threshold to keep examiner procedures uniform. States that deviate usually do so because of a different question count: a state with a short 18-question test (like Pennsylvania) can't hit exactly 80% on a whole number of questions, so the effective bar lands a little above or below.

Hardest and easiest states by the numbers

Raw percentage is misleading — what actually determines difficulty is your margin for error: how many questions you can miss and still walk out with a permit.

• Tightest margin: Alaska — you can only miss 4 questions out of 20. Every single question carries real weight, so a couple of careless misreads can end the attempt.
• Widest margin: Oklahoma — up to 12 misses allowed out of 50 questions. A longer test with proportionally more slack rewards steady, unrushed reading.
• Highest percentage bar: Maryland at 85% — versus Maine at the national low of 70%.

The takeaway: don't assume your friend's experience in another state applies to you. Check your row in the table above, note the "Need Correct" column, and treat that number — not the percentage — as your real target.

How is the passing score calculated?

The percentage is converted to a minimum number of correct answers, always rounded in the state's favor. If your state requires 80% on a 25-question test, you need 20 correct; missing 6 fails you. A few states add wrinkles worth knowing about:

• Category minimums. Some testing systems require competence across sections — acing every road-sign question while missing most right-of-way questions can still fail, because the sampling algorithm draws from each category.
• Instant-stop scoring. Computer-based tests in several states end the moment you either reach the passing number or exceed the allowed misses — you might answer only 15 of 36 questions and pass, or fail at question 9.
• Age-based differences. A handful of states test under-18 applicants on more questions (or a stricter bar) than adult first-timers, reflecting graduated-licensing rules.

What happens if you fail?

Failing is more common than most first-timers expect — national pass rates for first attempts hover around 50-60%. What happens next varies by state along three dimensions:

• Waiting period. Some states allow a retake the next business day; others enforce a mandatory 7-14 day study window after each failure, and a few extend the wait after the second or third miss.
• Attempt limits. Commonly three attempts per application or per fee. Exhaust them and you'll typically pay a new application fee, and in a few states complete a driver-education course before trying again.
• Retest fees. Several states charge per attempt (usually $5-$25), which turns careless first attempts into real money. Passing on attempt one is the cheapest route in every state.

Your state's exact retake rules, fees, and waiting periods are listed on its test page — find yours in the table above.

Why this matters for studying

Knowing your exact threshold changes how you should prepare. If your test allows 12 misses, perfectionism is wasted effort — spend your remaining study time exclusively on your weakest categories rather than re-reviewing what you already know. If you're in a tight-margin state, do the opposite: drill until your practice scores sit comfortably above the bar (we recommend 90%+ three runs in a row), because test-day nerves reliably shave off a few points. Our Challenge Library automatically tracks which topics you miss most, and each state's practice tests mirror the real exam's category mix.

Moving to a new state?

If you already hold a valid license from another state, most DMVs waive the knowledge test entirely when you transfer within the grace window (usually 30-90 days after establishing residency). Let it lapse, though, and you're treated as a new applicant — full written test at the new state's passing bar. The same is true for some license upgrades: adding a motorcycle endorsement means a fresh knowledge test at your state's Class M threshold, and any CDL class or endorsement is a federally mandated 80% regardless of what your state requires for regular licenses.
