PA CDL General Knowledge Practice Test 4 2025

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

This fourth PA General Knowledge practice test contains another set of 50 multiple-choice questions based on the official CDL manual. Just like our other practice tests, this one is also designed to prepare you for the General Knowledge portion of your 2025 Commercial Driver’s License exam. There are several answer options, but only one of them is correct. Each question also includes a hint and an explanation. It is recommended that you check each question’s explanation to gain some further insight into the rule being tested. Every time you answer a question, you’ll get immediate feedback with a detailed explanation, so you won’t need to wait until the end of the test to know the correct answers. Good luck and drive safely!

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.
