Oregon Pre-Trip Inspection Test

About the Oregon Pre-Trip Inspection Test

Oregon's roads throw you curveballs. You'll climb the Coast Range, descend into the Willamette Valley, and cross the high desert east of the Cascades. Each route demands a thorough pre-trip inspection. Don't skip a single step – your safety and your CDL depend on it.

Weather here changes fast. Fog in the Gorge, ice on Santiam Pass, sudden rain near Portland. Your vehicle's lights, tires, and brakes must handle it all. That's why Oregon's CDL test focuses on real-world conditions. You'll need to identify problems before they become emergencies.

Logging trucks, farm loads, and chip vans share the road with you. These industries keep Oregon moving. Your pre-trip inspection shows you understand the weight, permits, and cargo securement rules. Use this practice test to build that confidence.

Each question comes from the Oregon CDL manual. You'll see the same format the DMV uses. Answer correctly, and you'll walk into your test ready. No surprises.

What This Test Covers

• Air Brakes – Oregon's mountain passes demand reliable braking. You'll check slack adjusters, air loss rate, and low-air warning devices.
• Lights & Reflectors – Fog, rain, and darkness hit Oregon year-round. Verify every light works so other drivers see you.
• Tires & Wheels – Gravel roads and sharp rocks damage tires fast. Check tread depth, inflation, and lug nuts.
• Steering & Suspension – Curves on Highway 101 can wear out components. Look for loose or broken parts you can spot from the ground.
• Coupling Systems – Log trailers and fifth wheels need secure connections. Practice the tug test and air line hookup.
• Cargo Securement – Oregon's forest products require proper tie-downs. Learn the number of straps needed for different loads.

Study Tips

Don't just read the manual – get hands-on. Park your truck at home and run through the entire walk-around. Time yourself. You'll have 30 minutes on test day, but don't rush. The inspector expects you to point and name every part.

Practice your engine start procedure. In Oregon, you must say the words out loud. 'I am checking the parking brake.' 'I am checking the air gauge.' Use the phrases from the manual. It's not weird – it's required. Record yourself and play it back. You'll catch mistakes.

Focus on Oregon's unique items: the exterior lights check includes the headlight dimmer switch, and you must explain how you'd test the ABS light. Also, know the tire section: minimum tread depth is 4/32 for steering tires, 2/32 for others.

Oregon DMV Information

Oregon DMV offices in Portland (Northeast 99th), Salem (Mission Street), and Medford (North Fir Street) offer CDL skills tests. You must schedule your pre-trip test online through the DMV appointment system. Walk-ins aren't accepted. The test fee is $11 for the CDL permit knowledge test; the skills test costs $88. Pay with credit or debit card – no cash at most locations.

Bring your own vehicle. It must pass a basic safety check before the inspector starts. The vehicle must be registered and insured in your name or your employer's. Make sure the windshield isn't cracked directly in the driver's line of sight. Oregon enforces that rule strictly.

If you fail, you can retest after 7 days. You get two attempts within a year before you must reapply. Use those attempts wisely – practice between them.
