Take our free Pennsylvania CDL Permit Practice Test! Each free cdl (trucks and buses) practice test contains randomized rule and sign driving test questions taken from a comprehensive database of PA test-specific questions. These questions are based on the official driver handbook, so that the questions most closely mirror the actual driving test, administered by the Pennsylvania Driver and Vehicle Services. Please note that each time you take a test on our website, you will get a different set of randomized questions, creating an excellent learning experience so we can prepare you to pass your test. Good luck and please let us know if you come across any questions on the actual test that stump you! Happy driving!
