What the Course Entails and Exam Details

The Pre-Trip Inspection exam covers a comprehensive evaluation of the commercial vehicle’s components. Students must be prepared to inspect several key areas, including:

• Engine Compartment: Checking fluid levels (oil, coolant, power steering), belts, hoses, and the air compressor.

• Cab Check/Engine Start: Demonstrating knowledge of the dashboard gauges, warning lights, emergency equipment (fire extinguisher, fuses, triangles), and conducting critical air brake tests (leakage, warning light/buzzer, and tractor/trailer protection valve pop-out).

• External Inspection: Evaluating the front of the vehicle (lights, tires, suspension, steering), the side of the vehicle (fuel tanks, doors, mirrors), and the coupling system (for Class A combinations, checking the fifth wheel, kingpin, and air/electrical connections).

• Trailer (if applicable): Inspecting the sides, tires, suspension, brakes, and rear of the trailer.

During the exam, the applicant must walk around the vehicle, point to specific components, and clearly explain what they are checking and why.

What to Expect in the Final Exam

The Oregon Pre-Trip Inspection is a hands-on, practical demonstration administered by an Oregon DMV examiner or an authorized third-party tester. It is not a written, multiple-choice test.

Applicants are required to verbally identify vehicle components and accurately describe what they are inspecting for (e.g., "Checking the tire for properly inflated, no cuts or bulges; minimum tread depth is 4/32 inch").

While there isn't a strict time limit solely for the pre-trip portion, the entire CDL skills test appointment (which also includes the basic control skills and road test) typically lasts around 90 minutes. Points are deducted for missed components or incorrect explanations. To pass the Pre-Trip Inspection, applicants must successfully check and describe a significant percentage of the required items before they can proceed to the driving portions of the skills test.

How to Study and Exam Centers

Preparation is crucial for passing the Pre-Trip Inspection on the first attempt. Effective study strategies include:

• Review the Oregon CDL Manual: Study Section 11 of the official Oregon Commercial Driver’s Manual extensively. This section outlines exactly what the examiners are looking for.

• Practical Application: Practice the inspection routine repeatedly on an actual commercial vehicle similar to the type you will be testing in.

• Memorize a Script: Develop a consistent, memorized routine (start from the front and work your way back, inside to outside) to ensure you don't miss any components.

• Utilize Study Aids: Use checklists, flashcards, and online pre-trip inspection videos to reinforce your memory.

The CDL skills tests, including the Pre-Trip Inspection, are conducted at specific Oregon DMV testing locations and authorized third-party testing facilities. You must schedule these appointments in advance through the Oregon DMV website or by contacting an approved third-party test site.
