View All PlansThe Beaver State is a great place to start your commercial driving career. With so many companies requiring CDL-licensed drivers, lots of opportunities await you. Passing the Oregon DMV CDL General Knowledge Test is required for operating a commercial motor vehicle, no matter which class of CDL you pursue. Oregon enforces a minimum passing score of 80%, and failing the exam results in delays and added fees. To help you pass this hurdle on your first attempt, our Free Oregon CDL Test Questions & Answers General Knowledge Practice Tests are scientifically crafted with amazing features. By focusing immediately on what Oregon actually tests, using material drawn directly from the current state Commercial Driver Manual and applicable federal standards, our practice materials include everything you need to pass with flying colors.
Unlike outdated PDF packets and printable study guides that no longer reflect real testing conditions, this practice test mirrors the sometimes tricky wording and structure used in the exam. We help you go beyond memorization to develop conceptual understanding, a level that is necessary for modern editions of the official exam. Our system presents multiple-choice questions with immediate AI-enhanced explanations, so you can learn as you go, rather than holding all assessments until the end of your practice session.

The Knowledge Test expects you to understand the management of speed and space on long downgrades, control a vehicle in rain, fog, snow, and ice, recognize hazards early, handle railroad crossings correctly, and respond to emergencies with sound judgment. You are also tested on fatigue management, braking and shifting techniques, skid control, and mountain driving practices. Additionally, commercial drivers in Oregon are expected to understand federal drug and alcohol regulations, participation in the FMCSA Drug and Alcohol Clearinghouse, and the state’s medical self-certification requirements.
Our experts have removed fluff from our practice tests and focused on what Oregon evaluates. With built-in tracking that revisits missed questions until concepts are fully understood (our trademarked Challenge Bank), this method gives you a clear advantage as you learn.
