Oregon CDL Practice Test

Oregon DMV doesn’t publish its test sizes; tests end once enough answers decide a pass or fail. Our practice tests follow the usual CDL format: General Knowledge 50 questions (40 to pass), Hazmat 30 (24), Air Brakes 25 (20), and Combination, Tank, Doubles/Triples, Passenger and School Bus 20 each (16). Oregon Commercial Driver Manual p. i-3

The Oregon Commercial Driver Manual (form 36M, AAMVA 2025 edited for Oregon): Oregon’s own rules, then inspection, safe driving, cargo, passengers, air brakes, combination vehicles, doubles and triples, tankers, hazardous materials and school buses.

Yes, as terminals allow, with a fee each time. Tests are in English only with no interpreters, and passed scores stay valid for six months. Oregon Commercial Driver Manual p. i-3

Yes, all but one: hand in a current CDL from another state or Washington, D.C. for a comparable Oregon CDL and every knowledge test is waived except Hazardous Materials. A learner permit from elsewhere doesn't count.

80% on each of the 8 tests, each graded on its own (General Knowledge: 40 of 50). Every test's numbers are in the table on this page. Always confirm the current tests with the Oregon Department of Transportation, Driver and Motor Vehicle Services. Why 80% in every state →

Qualify for a Class C license, be 18 (21 for interstate), have a year of Class C driving experience, pass a vision screening, file a medical certificate and hold an Oregon CLP 14 days before the skills test. Oregon Commercial Driver Manual p. i-1

All three segments on the same day, in English, in a vehicle with a legible VIN plate. A failed segment can be retaken the next day, and results stay valid six months. Oregon Commercial Driver Manual p. i-4

No. DMV stopped issuing, renewing and replacing limited-term (non-domiciled) CLPs and CDLs on September 29, 2025, and ended the program on March 16, 2026 for good. Current ones stay valid until they expire but can’t be renewed or replaced, and DMV gives no tests to limited-term applicants.

Oregon Department of Transportation, Driver and Motor Vehicle Services lists the current fees for the commercial learner permit, the CDL tests and the license on its official fee page.

Oregon sends applicants to third-party CDL testers to book it. The vehicle can't carry any load, be placarded, pull more than one trailer, or pull a trailer with no brakes or surge brakes, and it must be legal and safe.

The Hazmat and Doubles/Triples endorsements can't be added to a permit. A permit can carry its own restrictions instead: P, no passengers in a bus, and X, no cargo in a tank.

Oregon offers three: non-excepted interstate, excepted interstate and non-excepted intrastate. The DMV recommends non-excepted interstate if you meet the federal rules and might ever drive in interstate commerce, which can happen without leaving Oregon; otherwise your CDL is restricted.

No, if you can prove you once held a Class A or B CDL, or the endorsement you're after (Passenger, School Bus or Hazmat), or got a military skills test waiver. Everyone else finishes the training before booking a skills test or taking the hazmat knowledge test.

Oregon lists three exceptions: recreational vehicles for personal use, emergency fire vehicles driven by firefighters, and emergency vehicles driven by qualified emergency service volunteers. For everyone else, a vehicle's weight is its weight rating or its actual weight, whichever is greater.

Possibly. Oregon DMV offers a Waiver of Physical Disqualification, but it covers only intrastate or excepted interstate driving. Interstate drivers may instead seek a federal exemption for hearing or seizure disorders, or a Skills Performance Evaluation for a limb impairment. Carry the waiver or exemption papers whenever you're on duty.

Three parts. In the pre-trip inspection you check the vehicle and tell the examiner what you're looking at and why (manual Section 11). Basic control tests handling and judging the vehicle's position (Section 12). The road test takes in turns, intersections, rail crossings and curves on both two-lane and multi-lane roads and highways (Section 13).

At least 180 days the first time, one year for two violations in ten years, and three years for three or more. Oregon Commercial Driver Manual p. i-4

No diversion for anyone holding commercial privileges, even expired ones. A hardship permit never covers a CMV, and getting one for a car means surrendering the CDL. Oregon Commercial Driver Manual p. i-4

For Class A or B, yes, if a main duty of your military job, now or within the last 12 months, is driving a commercial-type vehicle. Send the waiver application, signed with your commanding officer, plus your DD 214 or military ID and vehicle operator's permit; it must be approved before you go to a DMV office. Passenger and School Bus skills tests are never waived.

For the air brake (L) restriction, pass the Air Brakes knowledge test and a vision test, get a CLP, then pass all three skills segments in a vehicle with air brakes. For the automatic-only (E) restriction, take the same steps without the knowledge test, testing in a manual vehicle. Both end with a replacement license.

Oregon DMV knows of no Class A passenger vehicles driven in the state, so every passenger endorsement carries one. M allows Class B and C passenger vehicles; N allows Class C only. To change N to M, pass the skills test in a vehicle rated over 26,000 pounds.

Hold a Class A CDL or meet its requirements, pass the Doubles and Triples knowledge test and a vision screening, and pay for a replacement license. Oregon lists no extra skills test for it.

Five years, and a new one can take 60 days or more, so start early with TSA's Universal Enrollment Services. If you move to Oregon with a hazmat endorsement, you need a new check when your last one is more than 4 years and 9 months old.

Yes. If your latest license or permit was commercial, you still count as a commercial driving privilege holder when it has expired or is suspended, canceled or revoked. You stop counting only if you voluntarily surrendered it, or your CLP expired and your latest license wasn't a CDL.

Sometimes. Two major offenses, such as DUI or refusing a test, mean a lifetime suspension, but you may qualify for reinstatement after 10 years under OAR 735-063-0380. A new major offense during those 10 years restarts the clock, and one after reinstatement means life with no reinstatement.

Yes. Failing a breath or blood test at 0.08% or more in any vehicle is a major offense for a CDL or CLP holder, bringing a one-year suspension, the same as a DUI conviction or refusing the test.

Reckless driving, driving 100 mph or faster, and speeding by 30 mph or more when the court suspends your license all count as serious offenses in any vehicle. Two serious offenses within three years mean a 60-day CDL suspension; three or more, 120 days.

DMV suspends your CDL or CLP. That applies to a traffic case in any state while you hold commercial privileges, and to one from driving a commercial vehicle.

Often, on DMV2U: if your photo is under nine years old, you don't want a REAL ID, you have no farm or hazmat endorsement and you aren't changing any. Drivers 65 or older renew in person with a vision test. You can renew from 12 months before expiry to two years after; later than that you apply and test as a new driver.

Renew at a DMV office, pass the hazmat knowledge test again and show a TSA security check passed within the last 4 years and 9 months.

From the FMCSA National Registry: your examiner uploads it by midnight of the next day and it reaches your DMV record electronically. A new one must be on file before the old one expires, and tracking that date is up to you.
