Oregon CDL permit test: what to expect
The written exam most people call the Oregon CDL permit test is the general knowledge test, and passing it is what gets you a commercial learner's permit rather than the license itself. You need 80% to pass, a federal standard that is the same in every state. The number of questions is set by Oregon, and our practice tests use the common 50-question format.
Once you hold the permit you have to keep it for at least 14 days before you are allowed to attempt the skills test, so it is worth sitting the written exam as early as you can. Practice below until you are clearing Oregon's standard comfortably rather than scraping it.
