About the Colorado Passenger Test
Topics Covered
- ✓Pre-trip inspection for passenger vehicles – Colorado's altitude and temperature swings mean tire pressure and brake checks aren't optional; they're critical for safety.
- ✓Loading and unloading passengers – With ski resort shuttles and school bus routes, you need to handle crowded stops and wheelchair lifts properly.
- ✓Mountain driving and braking – On I-70's long downgrades, brake fade kills. You'll need to know how to use engine braking and when to pull over.

📘 Study Tips & State Info
Colorado DMV examiners love the pre-trip inspection. They'll ask you step-by-step what you check on a bus — from the engine compartment to the passenger door to the emergency exits. Don't just memorize a list. Understand why each item matters for a bus carrying people. For example, when you check the brakes on a bus, you're not just looking for air leaks. You're making sure the bus can stop on a 7% grade.
Mountain driving questions come up a lot. The test will ask about downgrade speed, escape ramps, and what to do if your brakes overheat. In Colorado, those escape ramps on I-70 aren't theoretical — they're real. Know where they are and how to use them. Also, expect questions about passenger management during an emergency. Colorado examiners want to know you can keep people calm while evacuating.
Use the Colorado CDL manual. Don't skip the section on passenger endorsements. And take our practice tests until you're scoring 90% or better. That way, when you sit down at the DMV computer, you'll be ready for anything they throw at you.
Colorado DMV handles all CDL testing. You can take the Passenger endorsement test at any full-service driver license office. Popular locations include the Lakewood office (1881 W. Bayaud Ave.), the Colorado Springs office (320 W. Fillmore St.), and the Grand Junction office (222 S. 6th St.). Appointments are strongly recommended — walk-ins wait hours. Book online at dmv.colorado.gov.
The fee for the written knowledge test is $30.25 (as of 2026). You'll need to bring your current CDL learner's permit, a valid Medical Examiner's Certificate, and proof of identity. The test is on a computer, and you'll get your results immediately. Pass? Great. You can move on to the skills test. Fail? You can retake it the next day, but you'll pay the fee again.
One unique Colorado rule: If you drive a school bus, you need both the Passenger endorsement and the School Bus endorsement. The Passenger test covers general bus safety, while the School Bus test adds student management and crossing procedures. Don't confuse the two.
About the Colorado Passenger Test
Colorado's Passenger endorsement isn't just a checkbox. If you're driving a bus carrying 16 or more people — including the driver — you need this. That includes school buses, shuttle vans, tour buses, and transit buses. And in Colorado, those buses run on some of the toughest roads in the country.
Think about it. You might take a charter group up I-70 from Denver to Breckenridge. That means the Eisenhower Tunnel at 11,158 feet, steep grades, and sudden snowstorms that roll in without warning. Or you could be driving a city bus in Colorado Springs, dealing with elevation changes and passenger safety at every stop. The Passenger test covers all of that — vehicle inspection, loading and unloading, emergency procedures, and mountain driving techniques.
The test is 20 multiple-choice questions. You need 16 correct to pass — 80%. The Colorado DMV administers it at driver license offices statewide. You'll take it on a computer, and you get about 25 minutes. Most people finish in 15 if they know the material.
Don't treat this like a generic test. Colorado examiners expect you to know how altitude affects brake performance and why you can't just follow the same procedures you'd use in flat terrain. This practice test will help you think like a Colorado bus driver.
