The DMV written test is the knowledge exam every U.S. state requires you to pass before it will issue a learner’s permit. It’s a multiple-choice test drawn directly from your state’s driver handbook, usually 20 to 50 questions long, and most states set the passing score at 80%. Study the handbook your state publishes, take a few free practice tests from the same DMV website, and the exam itself is straightforward.
What the Test Covers
Every question comes from your state’s official driver handbook. Topics are more consistent from state to state than people expect, and they cluster into a handful of categories.
- Traffic signs and signals. You need to tell regulatory signs (speed limits, stop, yield) from warning signs (curves, construction) and informational signs (highway markers, hospitals). Expect at least one question on what a flashing red light means versus a flashing yellow.
- Right-of-way rules. Who goes first at a four-way stop, yielding to pedestrians in crosswalks, and giving way to emergency vehicles. This category trips up a lot of test-takers.
- Lane markings. Solid versus broken yellow center lines, double white lines, and the arrows painted in turn lanes.
- Speed laws. The posted limit and the “basic speed law,” which requires you to drive at a speed safe for weather, traffic, and road conditions regardless of the sign.
- Impaired driving. The legal blood alcohol concentration is 0.08% for drivers 21 and older in every state except Utah, which uses 0.05%. For drivers under 21, most states set the limit at 0.02%. Questions cover DUI consequences, including license suspension and jail time.
- Distracted driving. As of late 2025, 49 states ban texting while driving and 33 states prohibit all handheld cellphone use. Expect questions on when phone use is and isn’t allowed.
- Move over laws. Every state requires drivers to change lanes or slow down when approaching a stopped emergency vehicle, tow truck, or highway maintenance vehicle with flashing lights.
- School zones and school buses. When to stop for a bus with its red lights flashing, and reduced speed limits in school zones during posted hours.
How Many Questions and What Score You Need
The test runs anywhere from 20 to 50 questions depending on the state. New York and Alaska use 20-question exams. Florida, Michigan, Nevada, and New Jersey give 50 questions. California falls in between at 46. The passing threshold is most commonly 80%, but it ranges from about 70% to 85%. Maryland requires 85%. Massachusetts requires 72%. A few states also include a separate road sign section with its own minimum score.
Don’t assume a shorter test is easier. On a 20-question test at 80%, you can only miss four. On a 50-question test at the same threshold, you can miss ten. The shorter exams leave less margin.
How to Study
Your state’s driver handbook is the single best study resource. Every state publishes it free on its DMV website, and every answer on the test is in it. Read it through once, then go back and reread the sections covering right-of-way, lane markings, and signs, since those produce the most missed questions.
After the handbook, use the free online practice tests on your state DMV’s site. They pull from the same question bank as the real exam. Take them repeatedly until you’re scoring well above your state’s passing threshold. If you consistently score 90% or better on the practice tests, the real one won’t surprise you.
Taking the Test at the DMV
Most people still take the test in person. Some states require appointments, others accept walk-ins, and many offer both; scheduling online is almost always faster than waiting in line. Arrive with your documents ready, because a staff member verifies your identification and application before you’re allowed to start.
The test is usually given on a touchscreen computer, though some offices still use paper. You’ll stow your phone and personal belongings before you begin, and the testing area is monitored. A computer terminal scores your test the moment you finish. Paper tests take a few extra minutes while a staff member grades them.
Online Testing
A growing number of states let you take the knowledge test online from home. These programs typically require a parent or guardian to proctor minor applicants, and you may need to complete a proctoring verification form. Availability changes often, so check your state DMV’s website. Even if you test online, you’ll still need to visit a DMV office for your vision screening and photo.
Accommodations and Language Options
The Americans with Disabilities Act requires testing entities to provide accommodations so the exam measures your knowledge rather than the effects of a disability. Common accommodations include large-print or Braille versions, screen reading software, extended time, a separate distraction-free room, and in some cases a staff member who reads questions aloud or records your answers.
Many states offer the test in multiple languages. Some have only English and Spanish; others provide a dozen or more based on local demographics. Audio versions and American Sign Language video translations are available in some states. Contact your local DMV office or check its website for the specific options where you’ll test.
What to Bring
Expect to bring proof of identity, proof of your Social Security number, and two documents showing your residential address. For identity, most states accept a certified U.S. birth certificate, a U.S. passport, or a permanent resident card. The residency documents are usually utility bills, bank statements, or official mail with your name and address. Bring your Social Security card or another document showing the full number. If you’re applying for a REAL ID-compliant permit, these same documents satisfy the federal requirements, though your state may list additional specifics.
Application fees vary widely. Some states charge nothing; others charge up to about $65. The median is around $20. A few states bundle the knowledge test fee into the application; others charge a small separate testing fee. Most offices take credit cards and money orders. Fees are generally non-refundable even if you fail.
If you’re under 18, a parent or legal guardian almost always needs to sign your application. The adult who signs typically accepts legal responsibility for your driving, and in many states can later revoke consent, which cancels the permit. The signature usually must be given in person at the DMV or before a notary. Exceptions exist for minors who are married or legally emancipated, but you’ll need a certified marriage certificate or court order.
Some states ask applicants to disclose certain medical conditions, most often seizure disorders, episodes of loss of consciousness, and vision impairments below minimum standards. A vision screening happens at the office itself. The standard across most states is 20/40 acuity in at least one eye, with or without corrective lenses.
If You Fail
Failing means you don’t get your permit that day, but it isn’t a permanent setback. Most states impose a short waiting period before a retake, typically one to seven days. A few, like Wyoming, let you retake the same day. Some states give you two or three attempts within a single application fee; others charge a new fee for each try. If you run out of allotted attempts, you’ll generally need to file a new application and pay again.
Rather than burning through retakes, spend the waiting period in the handbook. Focus on the sections tied to the questions you missed, then run the online practice tests until you’re consistently above your state’s passing score.
What Passing Gets You
If you pass, the DMV processes your permit the same day. You’ll have your photo taken and typically leave with either a printed permit or a temporary document that holds you over until a permanent card arrives in the mail. Learner’s permits are generally valid for one to two years. If yours expires before you pass the road test, you’ll need to reapply and may have to retake the knowledge test.
A learner’s permit is not a full driver’s license. The universal rule is that a licensed adult must sit in the passenger seat whenever you drive, usually someone at least 21 or 25 years old with a valid unrestricted license. Most states add further conditions: a nighttime driving curfew (often between 10 p.m. or midnight and 5 or 6 a.m.), passenger limits, a minimum number of supervised practice hours (commonly 50, with 10 at night), and a mandatory holding period of six months to a year before you can take the road test. Violating any of these can bring a citation or permit suspension.
