What the Pennsylvania written test covers and how it's scored
Pennsylvania's written knowledge test has 18 questions, and you need to answer at least 15 correctly to pass. The test covers Pennsylvania traffic laws, road signs, safe driving practices, and what to do in emergencies. You take it on a computer at a PennDOT Driver License Center, and you get your score when ready after you finish.
The questions come from the Pennsylvania Driver's Manual, which is the official source for everything on the test. PennDOT does not publish the exact questions in advance, but every question on test day will be about material in that manual. You can read the manual online for free on the PennDOT website, or pick up a printed copy at any Driver License Center.
The test is offered in English and several other languages. If English is not your first language, you can request an interpreter at the Driver License Center when you schedule your test, though availability varies by location.

Topics the test focuses on most heavily
Road signs make up a significant portion of the test. You need to know what each sign means, what shape and color it is, and what action you should take when you see it. This includes warning signs (yellow diamonds), regulatory signs (white rectangles), and guide signs (green rectangles). The manual has a full section with pictures of every sign you might encounter.
Right-of-way rules are another major topic. The test asks about who goes first at four-way stops, at intersections with traffic lights, when turning left across oncoming traffic, and when merging onto highways. Pennsylvania has specific rules about yielding to pedestrians, cyclists, and other vehicles, and the test checks that you know them.
Speed limits and safe following distance come up regularly. Pennsylvania law sets a 55 mph speed limit on most highways unless posted otherwise, and the test asks about the two-second rule for following distance in normal conditions and longer distances in bad weather. You should also know the rules for school zones and residential areas.
Impaired driving, seat belt laws, and child passenger safety are also tested. Pennsylvania requires all front-seat passengers to wear seat belts and has specific rules about where children can sit and what type of restraint they need based on age and weight.
How to study using the Pennsylvania Driver's Manual
Start by reading the entire Pennsylvania Driver's Manual from beginning to end. It is organized by topic, so you can focus on one area at a time — road signs in one section, traffic laws in another, safe driving practices in a third. Take notes on anything that seems unfamiliar or confusing.
After you finish reading, go back through and focus on the sections that felt hardest. Road signs trip up many test-takers, so spend extra time on that section. Read the description of each sign, look at the picture, and think about what you would do if you saw it on the road.
Use the practice tests available on the PennDOT website. These are not the actual test questions, but they follow the same format and cover the same topics. Taking a practice test shows you which areas you still need to study and gets you used to answering questions on a computer.
Study a little bit each day rather than cramming the night before. Spacing out your study over a week or two helps the information stick in your memory better than trying to learn everything at once.
What to bring and what to expect on test day
Bring a valid form of identification to your test appointment. If you are under 18, bring your school ID or passport. If you are 18 or older, bring a passport, military ID, or other government-issued ID. You will also need to bring your Social Security number or Individual Taxpayer Identification Number.
Arrive at least 15 minutes early. The Driver License Center will check your ID, verify your information, and take your photo before you sit down at the computer. The whole process from arrival to finished test usually takes 30 to 45 minutes.
You cannot bring notes, phones, or study materials into the testing area. You can bring glasses or contacts if you need them to see the screen. The testing room is quiet, and you sit at a computer terminal with a staff member nearby if you have a technical problem.
The test is multiple choice. Each question shows you four possible answers, and you click the one you think is correct. You can go back and change your answer before you submit the test, but once you submit it, you cannot change anything. After you finish, the computer tells you whether you passed or failed and shows you your score.
What happens if you fail and when you can retake it
If you score below 15 out of 18, you fail the test. You can retake it, but the waiting period depends on your age. If you are under 18, you must wait at least one day before retaking the test. If you are 18 or older, you can retake it the same day if the Driver License Center has availability, or you can schedule another appointment.
There is no limit to how many times you can retake the written test in Pennsylvania. However, each attempt costs money — currently $20 for the knowledge test — so it makes sense to study thoroughly before you go back.
When you retake the test, the questions will be different from your first attempt. Study the same way you did before, focusing on the areas where you felt least confident. Many people pass on their second try after spending a few more days with the manual.
Differences between the knowledge test and the road test
The written test and the road test are separate. You must pass the written test first, and then you can schedule a road test with a PennDOT examiner. The road test is where you actually drive a car and show that you can handle it safely on real roads.
The written test checks what you know. The road test checks what you can do. You might know all the rules but still fail the road test if you cannot execute them — for example, if you know the rule about turning left but cannot do it smoothly without hitting the curb, or if you know you should check your mirrors but forget to do it during the test.
After you pass the written test, you will get a learner's permit. With a learner's permit, you can drive only with a licensed adult in the car. You must hold the permit for a certain amount of time before you can take the road test — the length varies based on your age.
Frequently Asked Questions
Can I use my phone or notes during the written test?
No. You cannot bring any study materials, notes, or electronic devices into the testing area. You can bring glasses or contacts if you need them to see, but nothing else. The test is proctored, meaning a staff member watches to make sure everyone follows the rules.
What if I do not understand a question on the test?
Raise your hand and ask the staff member at the Driver License Center. They cannot tell you the answer, but they can clarify what the question is asking if the wording is confusing. Some questions are worded in a way that takes a second read to understand.
Is the written test the same for all license types in Pennsylvania?
The basic knowledge test is the same for a Class D (regular car) license. If you are getting a commercial driver's license or a motorcycle license, you take a different test with different questions. Ask at the Driver License Center which test you need based on what license you are going for.
How long does the written test take?
Most people finish the 18-question test in 10 to 20 minutes. You can take as long as you need — there is no time limit. You can also go back and change your answers before you submit, so take your time and think through each question.
What score do I need to pass the Pennsylvania written test?
You need to answer at least 15 out of 18 questions correctly. That is about 83 percent. If you score 14 or lower, you fail and must retake the test. Your score is based only on the questions you answer correctly; there is no penalty for guessing.
