About the Colorado Pre Trip Inspection Test
Topics Covered
- ✓Brake system inspection — Colorado's steep grades on I-70 and Wolf Creek Pass demand perfect brakes. You'll need to check air pressure, slack adjusters, and brake chamber cracks.
- ✓Tire condition — High altitude and temperature swings in Colorado cause tire pressure to fluctuate. You must know how to spot worn tread, sidewall damage, and proper inflation.
- ✓Coupling devices — Trailer stability on winding mountain roads like US-40 means your fifth wheel, kingpin, and locking jaws must be secure. Miss a cracked jaw and you're in trouble.

📘 Study Tips & State Info
Colorado CDL examiners don't care if you're fast — they care if you're thorough. When you study, memorize the exact order of inspection: front of vehicle, driver's side, rear, passenger side. Don't jump around. If you miss a step during the skills test, that's an automatic deduction.
Focus on air brake checks. Colorado examiners love to ask about low air warning devices, brake lag, and how to test for leaks. Practice saying out loud: "I check the air gauge for pressure buildup, then test the low air warning by draining the system. It should activate between 55 and 75 psi." That's the kind of detail they want.
Also, get familiar with Colorado's specific requirements for winter driving. The exam might ask about chain installation points and when you need to carry chains. Even if the test doesn't, the examiner will expect you to know. Tie every study point back to a real Colorado road — it'll stick better.
Colorado CDL testing is handled by the Colorado DMV at regional offices. Major testing locations include Lakewood (main office), Colorado Springs, Grand Junction, and Fort Collins. You must schedule an appointment for the skills test — walk-ins aren't accepted. The written knowledge tests (including this one) can often be taken without an appointment, but check your local office first.
The CDL skills test fee in Colorado is $95 for the combination vehicle test (Class A) and $75 for single vehicle (Class B). The pre-trip inspection is part of that skills test — no separate fee. You'll need to bring a valid Medical Examiner's Certificate, your CDL permit, and a properly equipped vehicle. If you fail the pre-trip portion, you can retest after a waiting period, but you'll pay the full skills fee again.
Colorado has a unique requirement: you must provide your own vehicle for the skills test. That vehicle must pass a basic safety inspection before the test starts. If your truck has a cracked windshield or a burned-out light, they'll send you home. Use this practice test to make sure you know what they're looking for.
About the Colorado Pre Trip Inspection Test
The Colorado CDL Pre Trip Inspection isn't just a written test — it's your ticket to the skills exam. In Colorado, the pre-trip inspection is part of the road test. You'll have to walk around your rig and explain what you're checking to the examiner. This practice test covers the same knowledge points they'll expect you to know cold.
Colorado's roads are different. You'll haul loads through I-70's mountain passes, down long grades on US-6, and into construction zones on I-25. That means your brakes, tires, and coupling systems need to be perfect. A blown brake line on Floyd Hill isn't a minor issue — it's a crisis. This test prepares you for the real inspection you'll do on the road.
The written portion focuses on inspection procedures, air brake systems, and emergency equipment. You'll get questions about proper tire pressure at altitude, how to check slack adjusters, and what to do with a cracked spring hanger. Colorado examiners want you to know the order of inspection — start at the front, go around the vehicle, and don't skip anything.
Take this practice test seriously. The real CDL skills test in Colorado has a 30-minute pre-trip inspection segment. If you can't pass this written practice, you won't pass the road test. Study the Colorado CDL manual, especially the inspection section. Then run through this test until you're scoring 90% or better.
