To pass the permit test, you generally need to answer 70% to 83% of the questions correctly, which translates to somewhere between 15 and 40 correct answers depending on your state. The total question count ranges from as few as 18 to as many as 50, so the exact number you need is set entirely by where you take the exam. Your state’s driver handbook and DMV website list the specific count and passing threshold.
Passing Scores in Major States
There is no national standard. Each state sets its own question count and passing percentage, and most land in a narrow band: 20 to 50 multiple-choice questions with a passing score between 70% and 83%.
Here is how that looks in several of the most populated states:
- California: 46 questions, 38 correct to pass (about 83%)
- Florida: 50 questions, 40 correct to pass (80%)
- New York: 20 questions, 14 correct to pass (70%)
- Pennsylvania: 18 questions, 15 correct to pass (83%)
- Ohio: 40 questions, 30 correct to pass (75%)
- Georgia: 40 questions split into two sections of 20, with 15 correct needed per section (75%)
If your state isn’t on that list, check the DMV website directly. The handbook will state the count and threshold on the pages describing the knowledge exam.
Why Fewer Questions Can Mean Less Room to Miss
The percentages look similar across states, but the actual margin for error is not. Pennsylvania gives you only 18 questions at an 83% threshold, so you can miss just three. Florida gives you 50 questions at 80%, which lets you miss ten. A short test with a high passing percentage is unforgiving in a way the number alone doesn’t suggest, and that math trips people up more often than the content does.
Before you walk in, do the arithmetic for your own state. Know the exact number of misses you can afford. It changes how you pace yourself on the questions you’re unsure about.
States That Split the Test Into Two Parts
In several states, a strong overall score isn’t enough. The exam is split into a road signs section and a general knowledge section, and you have to pass each one independently.
Georgia gives you 20 road sign questions and 20 road rules questions, with at least 15 correct required on each. Illinois splits its 35-question test into 15 sign identification questions and 20 rules questions. New York folds the requirement into a single 20-question test but still requires at least 2 of the 4 road sign questions to be correct, on top of the 14 correct overall. Virginia has a dedicated 10-question road signs portion alongside its general knowledge section.
If your state uses a split format, treat signs as their own study category. People who focus on rules and skip sign recognition pass one half, fail the other, and retake the entire exam.
What Happens If You Miss the Cutoff
Failing isn’t the end of the process. Every state allows retakes, but the waiting periods and attempt limits vary. Some states let you try again the next day; others impose a wait of up to a week. California, for example, requires a seven-day wait for minors.
Most states allow three attempts on a single application before you have to start over with a new application and a new fee. Application fees generally run between $15 and $50. After you exhaust your attempts, some states also restart the waiting period, so failing three times in quick succession can set you back several weeks once reapplication processing is factored in.
The practical takeaway: it’s cheaper and faster to over-prepare for the first attempt. If you have already failed once, treat it as diagnostic. Most DMV offices will tell you which topic areas you missed, and some will point you to specific handbook pages. Focus your studying there before trying again.
How to Make Sure You Hit the Number
The national pass rate for knowledge tests hovers around 62%, meaning roughly one in three people fail on their first try. That is a high failure rate for a test where every answer is printed in a free handbook. The people who fail have almost always skimmed the handbook or skipped it, relying on common sense. Common sense gets you through maybe half the questions. The rest tests specific rules you wouldn’t guess correctly without studying.
The effective approach is simple. Read your state’s driver handbook cover to cover, then take practice tests. Every state DMV website offers the handbook as a free download. Give yourself several days rather than cramming the night before, and spend extra time on signs, right-of-way, and impaired driving, since those areas are heavily tested in every state.
Practice tests are available on most state DMV websites and on free third-party platforms. They use the same question format as the real exam and often pull from the same question bank. Keep taking them until you consistently score above the passing threshold. When you miss a question, look up the answer in the handbook so you understand the rule rather than memorizing a letter. The handbook is the single source for every question on the official exam, so anything that seems oddly specific in those pages is exactly the kind of detail that shows up on test day.
