PA CDL General Knowledge Exam Simulator 2025

Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements.

Commercial drivers in Pennsylvania have a wide range of jobs to choose from. Industries such as manufacturing, distribution, and agriculture require a constant flow of goods across the Keystone State. However, delivering heavy equipment and transporting hazardous materials are difficult tasks involving great responsibility. Since even a small mistake can lead to disaster, road safety is an important topic that should be prioritized in your study sessions. In Pennsylvania, you will encounter varying road conditions. From busy cities like Philadelphia to rural highways, you must be ready for anything. The official Pennsylvania commercial driver’s manual (Pennsylvania CDL Handbook 2025) contains useful information on the various aspects of commercial driving theory. We recommend reading its contents at least once before incorporating other tools into your study routine.

The official CDL General Knowledge (permit) exam consists of 50 multiple-choice questions. You must answer them before the timer ends and score 80% or higher to pass. If you fail, you must pay a re-test fee and retake the exam no sooner than the next business day. Don’t rely on luck to pass. Instead, you should use our Pennsylvania CDL General Knowledge Exam Simulator to prepare in advance and build the knowledge and confidence necessary to obtain a passing score on your first attempt. You get unlimited attempts and nonstop access to this intuitive tool, which can be used even by those not skilled with computers. We have opted for a simple interface and omitted any timer for your convenience.

Understanding the most complex aspects of commercial driving theory can be difficult, especially if you are unfamiliar with this subject. Although this simulator will not provide any feedback, you can visit your personal Challenge Bank™ to learn from your mistakes. This section includes detailed explanations for the questions you got wrong during your previous sessions. As you study regularly with our simulator, your knowledge will naturally increase over time. Within a few weeks, you’ll be ready to take the official exam and ace it on your first attempt.

Follow the plan!
As long as you follow the plan that you are given, you will pass. I passed my Hazmat & Tanker endorsement on the same day.

Makes it too easy to pass.
Easy to sign up for and access the Information and practice tests. All the questions on the practice tests were on the PA Hazmat\Tanker tests, passed first time with 0 wrong.

Absolutely 💯%.
Absolutely 💯% you spend. I crammed for less than 24 hours and passed my PA CDL general knowledge as well as endorsements for Hazmat, Combination, Doubles/Triples, and Tank IN ONE TRY! The practice exams were tremendously thorough and matched nearly all the questions that I encountered on the actual exams. Don’t waste anymore time or money at the DMV then you absolutely must! Sign up for Driving-Tests and pass the first time!

Honest expierence.
My honest experience with this website has been awesome! I have the cdl book from the dmv here in pa but never really opened it, every time I did I just got really bored, it wasnt working. I'm a hands on type of guy so I always get nervous for written exams. But when I aced all of these tests, I decided to go to the dmv and give it a shot. I went for class a with airbrakes. I was really surprised at how close the questions on my actual test were similar to the ones on this site. If it wasnt for the little money I played for this site, I don't think i would've got my cdl. These guys are great and I'll recommend them to anyone who is attempting their cdl. Thank you so much for helping me advance my career, your help made this process a breeze.
