About the Oregon Pre Trip Inspection Test
Topics Covered
- ✓Air brake system inspection — Oregon's mountain grades require you to know your brakes are perfect before descending. One failed chamber can mean losing control on a 6% grade.
- ✓Coupling systems — logging trucks on rough forest roads need secure fifth wheels. Oregon examiners watch how you check the jaw and release handle.
- ✓Lights and reflectors — Oregon's fog and rain mean you can't skip checking these. Dead tail lights get you pulled over on I-84.

📘 Study Tips & State Info
Oregon DMV examiners emphasize the walk-around pattern. They want you to start at the front, go driver's side, then rear, then passenger side, and finish at the front. Don't skip around — they'll ding you for it. Focus on the air brake check: build pressure, release, watch for leaks, then do the low-air warning test. That's where most people mess up.
Another thing: Oregon examiners sometimes ask you to show them a specific component, like the slack adjuster or the glad hands. They don't just want you to name it — they want you to touch it. Practice pointing and explaining out loud. If you're taking logs or heavy equipment, they'll also check your tie-downs and chain tension. That's a detail a lot of study guides miss.
Use the Oregon CDL manual, not some generic online list. Oregon's pre-trip requirements follow the state's specific inspection procedures, especially for combination vehicles. Memorize the order, practice with a friend, and don't skip the emergency equipment check. It's an automatic fail if you don't mention chains or flares.
Oregon DMV handles all CDL testing. You'll take the Pre Trip Inspection test as part of your skills exam after you pass the General Knowledge and any endorsement written tests. The skills test costs $90 (as of 2025) and requires an appointment. Walk-ins aren't available at most offices — you have to schedule online or by phone.
Major testing locations include Portland (NE 122nd Ave), Salem, Medford, Eugene, Bend, and Pendleton. Some of these offices only offer CDL skills tests on certain days, so check the schedule early. You'll need a valid Medical Examiner's Certificate and your CLP when you show up. Oregon also requires you to bring your own vehicle for the skills test — it must pass a basic safety inspection before you even start.
One unique Oregon rule: If you're taking the test during winter months (November through March), the examiner may ask about chain requirements. Your vehicle must have enough chains for all drive tires, and you need to know how to install them. That's not federal law — that's Oregon's specific requirement for mountain driving.
About the Oregon Pre Trip Inspection Test
The Oregon Pre Trip Inspection test isn't just a formality. It's the first thing you do during your CDL skills exam, and if you fail it, you don't get to drive. Oregon examiners are strict — they've seen thousands of drivers and know exactly where people cut corners.
This test covers your vehicle's major systems: air brakes, coupling, lights, tires, suspension, and emergency equipment. You'll need to walk around your truck and trailer, point to each component, and explain what you're checking. In Oregon, that includes being ready for mountain grades on I-5 over the Siskiyou Summit or hauling logs out of the Coast Range — your inspection has to hold up in real conditions.
The written version of this test (the one you take for your permit) has 25 multiple-choice questions. You need 80% to pass. But don't treat it like a trivia quiz — every question ties back to something you'll actually inspect on the day of your road test.
