Oregon CDL General Knowledge Practice Exam 2026

The Oregon CDL general knowledge test is the written exam every commercial driver must clear, and this 2026 simulator recreates it end to end. Sit it like the real CDL exam: no notes, no pausing, just you against a full-length cdl knowledge test that mirrors what the state actually asks.

So how big is the real thing? The commercial drivers license test for general knowledge is 50 questions, and you need 80 percent, which is 40 correct, to pass. That standard comes from the FMCSA and is federal, so it reads the same in Oregon as it does in any other state, regardless of whether you pursue Class A, B, or C.

Pass this rehearsal comfortably and you are ready for the counter; fall short and the miss shows you exactly which chapter of the Oregon commercial driver license manual to reopen. Treat every attempt as the genuine exam and test day becomes a formality.
