Pennsylvania CDL General Knowledge Practice Exam 2026

This Pennsylvania CDL general knowledge test simulator recreates the real exam experience for 2026, giving you a straight, no-frills run at the questions PennDOT actually asks. Treat it as the commercial drivers license test itself: no topic labels, no hints, just the mixed set you will face when it counts.

How many questions is the Pennsylvania CDL knowledge test, and what does it take to pass? The exam has 50 questions and requires an 80 percent score, so 40 correct answers clear it. That standard is set federally by the FMCSA and applies in every state, and the same written test also earns your Commercial Learner's Permit. Passing it is the gateway to the skills exam for whichever class you want.

Because this is a full CDL exam rehearsal, use it to gauge readiness rather than to learn from scratch. When a 2026 question here reveals a weak spot, go back to the Pennsylvania Commercial Driver's Manual and shore it up. Consistently scoring above 40 out of 50 is your green light to book the real PennDOT test.
