Oregon CDL Practice Test and Test Prep (2026)
Oregon gives CDL tests through Oregon Driver and Motor Vehicle Services (DMV), a division of the Oregon Department of Transportation (ODOT). Here is what you will be tested on, which of our practice quizzes match each test, and what the skills test involves in Oregon.
Knowledge tests for a Oregon permit
- General Knowledge (all applicants) — practice General Knowledge (60 questions)
- Combination Vehicles (Class A) — practice Combination Vehicles (30 questions)
- Air Brakes (if the vehicle has air brakes) — practice Air Brakes (40 questions)
- Any endorsement tests you need (H, N, P, S, T)
Permit minimum age: 18 (in-state driving) or 21 (interstate). Holding period before the skills test: 14 days. Permit validity: 365 days.
Oregon endorsement tests and practice
- Hazmat (H) practice
Oregon notes for this endorsement
Hazmat. Oregon is NOT a TSA self-managed state — you use the standard federal TSA process: pass the hazmat knowledge test, complete ELDT if first-time, and complete TSA security threat assessment/fingerprinting through TSA's contractor (start at the TSA website or Universal Enrollment Services, 855-347-8371). The background check can take 60 days or more.
- Tanker (N) practice
Oregon notes for this endorsement
Tank vehicle endorsement (liquids/gases in bulk). Requires the tank knowledge test.
- Passenger (P) practice
Oregon notes for this endorsement
Passenger. Requires ELDT for first-timers; Oregon passenger endorsements currently carry a restriction (M or N) limiting the passenger vehicle class.
- School bus (S) practice
Oregon notes for this endorsement
School bus. Requires ELDT for first-timers plus the passenger and school bus knowledge and skills requirements.
- Doubles/triples (T) practice
Oregon notes for this endorsement
Doubles/triples. Requires a Class A CDL and the doubles/triples knowledge test.
The Oregon skills test
Components: Pre-trip vehicle inspection, Basic control skills, On-road driving test.
Test vehicle: You must provide your own commercial vehicle representative of the class of CLP you hold; DMV/testers do not furnish a test vehicle. The vehicle must match the class, endorsements, and restrictions you are testing for.
Where and how to book: Oregon leans heavily on certified Third Party CDL Testers — applicants schedule the skills test directly with a third-party tester rather than a DMV field office. Tests are given in English only; translators are not permitted.
Waits and retests: Availability depends on the individual third-party tester's schedule; testers often set their own fees on top of the DMV's $40 third-party acceptance fee. Confirm current wait times with your tester (estimated market conditions, not a DMV-published figure).
Practice the inspection part with our pre-trip inspection guide. Research dated 2026-07-20; confirm testing details with Oregon.
