About the Nevada Combination Vehicles Test
Topics Covered
- ✓Coupling and uncoupling procedures — Nevada examiners expect the full sequence in order, especially for trailers parked on an incline (common around the mining operations in Elko).
- ✓Trailer stability and rollover prevention — Nevada’s mountain grades and desert crosswinds make this critical; you’ll learn how speed and load distribution affect rollover risk.
- ✓Jackknife causes and prevention — Snow and ice on I-80 near the California border can trigger a jackknife fast; know how to avoid it and how to recover if it starts.

📘 Study Tips & State Info
Nevada examiners are sticklers for the exact coupling sequence. Memorize it step by step — they’ll ask you the order of connecting air lines, electrical cables, and the fifth wheel. If you mix up the steps, you fail that question. Practice by saying the steps out loud while you’re in your truck or car.
Focus on braking on downgrades. Nevada has serious mountain passes, and the test includes questions about proper gear selection, brake fade, and using engine brakes. Don’t just read the manual — picture yourself coming down the east side of the Sierra into Reno. That context helps.
Also, Nevada DMV offices often add a question about securing trailers on steep roads. Know how to set the parking brakes and chock the wheels when you’re parked on a grade. It’s a common scenario in the mining areas around Battle Mountain.
Nevada DMV handles all CDL written tests. You’ll take the Combination Vehicles test at any DMV office that offers CDL testing — locations include Carson City, Las Vegas (Decatur and Flamingo offices), Reno, Elko, and others. Appointments are strongly recommended. Walk-ins are possible but you might wait hours. Book online at dmv.nv.gov.
The test costs $10 per endorsement (as of 2025). You need your Commercial Learner’s Permit first, which requires passing the General Knowledge test. Bring your Medical Examiner’s Certificate, proof of identity, and residency documents. Nevada doesn’t allow retakes on the same day — if you fail, you wait until the next business day.
One Nevada quirk: the DMV uses a computerized testing system. You get your score immediately after finishing. If you pass, the endorsement goes on your CLP or CDL right away. If you fail, you can study and come back — no limit on retakes, but each retake costs $10.
About the Nevada Combination Vehicles Test
The Combination Vehicles endorsement is a must for every Class A CDL applicant in Nevada. If you plan to drive tractor-trailers, doubles, or triples on Nevada roads, you’ll take this test. It covers coupling and uncoupling, trailer stability, and how to avoid jackknifes — all skills you’ll use daily on routes like I-80 through the Sierra Nevada or US-95 across the high desert.
Nevada follows federal CDL standards, but the state adds its own flavor. You’ll face questions about braking on long downgrades (think Donner Pass), crosswind handling on open highways east of Reno, and securing loads for mining and distribution. The test is 20 multiple-choice questions. You need 16 correct to pass.
Don’t underestimate it. Nevada examiners watch for procedural knowledge — they want the exact sequence for coupling, especially when you’re parked on an incline. They also emphasize trailer stability because Nevada’s mountain grades and desert winds can push a trailer around faster than you’d think.
Use this practice test to get comfortable with the format and the Nevada-specific details. Study the manual, but also picture yourself on I-15 between Las Vegas and Mesquite, or on US-50 through Fallon. That mental practice makes the answers stick.
