PA CDL General Knowledge Exam Simulator 2025

Want your commercial driver’s license in Pennsylvania? The General Knowledge Exam given by the Department of Transportation (DOT) in Pennsylvania is 50 tricky multiple-choice questions long. You have only one hour and if you get less than an 80% (that’s 40 questions right) you fail the test. Failure means you have to come back to take the test another day — you can’t take it more than once in a 24 hour period. That’s rough if you already were taking time off of work on a weekday to head into the office for the test. It’s important not to waste time. You want to pass on the first shot. To do that, you’ll need to pick up the official Pennsylvania Commercial Driver’s Manual and figure out how the questions on the test work. Your best bet is to take some of our CDL General Knowledge practice tests. Our tests feature questions that are very similar, if not identical, to the real thing. And with hints and performance tracking, you’ll see just what you need to work on to gain the confidence you need to pass on your first visit. But before you even see the test you need to make sure you have all your paperwork in order. The first thing they’ll want to check at the DOT is your DOT card. This is also known as a medical examiner’s certificate and can only be obtained by seeing a licensed medical examiner as listed by the Federal Motor Carrier Safety Administration (FMCSA) National Registry. This proves you are physically qualified to drive a commercial vehicle in Pennsylvania. Then you’ll also need proof of your citizenship or permanent legal residency status. For this, a green card, social security card, or birth certificate will work. Then lastly you’ll want to make sure you have a standard current valid driver’s license. With all the paperwork set, and after you’ve prepared properly for the exam, you should be able to sweep in and out of the DOT with a Commercial Driver’s License ready to go.
