📘 Study Tips & State Info
Wyoming DMV examiners focus on your ability to explain what you're looking for — not just point. When you check the engine compartment, say why you're checking the belt tension. When you check the fifth wheel, describe how you know the jaws are locked. They've seen too many drivers rattle off a memorized script and miss the actual problem.
Practice with the state's CDL manual. The pre-trip section has a detailed step-by-step. Walk around your truck or a friend's and say everything out loud. Do it in the cold. Do it in the wind. The test is indoors, but the conditions on the road aren't. If you can explain each inspection point in a Wyoming winter, you'll pass the written test easily.
Wyoming CDL testing is handled by the Wyoming Department of Transportation (WYDOT) Driver Services. You can take the written pre-trip inspection test at any WYDOT exam office. Major locations include Cheyenne, Casper, Rock Springs, Gillette, and Laramie. Most offices require an appointment for CDL written tests. Walk-ins are sometimes accepted but expect a wait. You'll need your commercial learner's permit (CLP) and a valid Medical Examiner's Certificate before testing.
The written test costs $10 per attempt. If you fail, you can retake it the same day in most offices, but you'll pay again. The pre-trip inspection test is part of the General Knowledge written exam for your CLP — you don't need a separate endorsement. After you pass the written, the pre-trip inspection skills test comes during your road test. You'll have to perform a full vehicle inspection for the examiner in person.
About the Wyoming Pre Trip Inspection Test
Wyoming's pre-trip inspection test isn't just a checkbox. It's the first thing your examiner watches you do, and it tells them everything about how you approach safety. On roads like I-80 between Rawlins and Laramie, a loose air line or a worn tire can kill you before you hit the next rest area. The test covers the same federal inspection points, but Wyoming examiners expect you to know them cold — and to show you understand why each item matters in wind, snow, and mountain grades.
The written test has 25 multiple-choice questions. You need 80% to pass. That's 20 correct out of 25. The questions pull from the Wyoming CDL manual's pre-trip section, but they're not trick questions. They test whether you can spot a problem before it becomes a breakdown. Topics include the engine compartment, cab checks, coupling systems, lights, brakes, and the vehicle exterior.
Don't just memorize a script. Learn what each component does and how failure affects your rig. Wyoming's oil fields and ranches mean you'll haul heavy loads over long, empty stretches. A pre-trip that catches a bad seal on a trailer brake chamber could save you from a runaway on a downhill grade. Treat this test like your life depends on it — because on Wyoming highways, it does.
