About the Kansas Combination Vehicles Test
Topics Covered
- ✓Coupling and uncoupling procedures – Kansas examiners want the exact order, especially for grain trailers that sit high and need a solid fifth wheel lock.
- ✓Off-tracking and trailer swing – narrow county roads in western Kansas mean you've got to know how a long trailer cuts corners.
- ✓Jackknife causes and prevention – ice on I-70 near Topeka can turn a simple brake tap into a jackknife if you don't understand trailer push.

📘 Study Tips & State Info
Kansas examiners don't care if you memorized every page of the manual – they care that you can apply it. The number one thing they emphasize is the coupling sequence. You'll get at least three or four questions on the exact order: check fifth wheel, back under, lock, test. Do not skip a step.
Second, know your winds. Kansas has more than its share of high-wind days, especially spring and fall. The test will ask about reducing speed in crosswinds and watching for empty trailers that catch the wind. Picture driving a flatbed with hay bales on I-70 near Colby – that's the scenario they want you to understand.
Finally, practice the air brake pre-trip. Even though this is a written test, the knowledge carries over to your skills exam. Kansas examiners watch your air brake check like a hawk. Know your low-air warning, spring brake application, and how to do a tug test on the trailer.
The Kansas DMV handles all CDL written tests at designated driver's license stations. You don't need an appointment at every location, but it's strongly recommended – especially at busier offices in Johnson County, Wichita, and Topeka. Walk-ins wait longer.
You'll need to bring your valid Kansas driver's license, Social Security card, proof of residency, and a current Medical Examiner's Certificate (DOT physical). The fee for the Combination Vehicles endorsement is $20, payable by cash, check, or card depending on the office. You can take the test as many times as you need, but you have to wait until the next business day after a fail.
Kansas does not add any state-specific endorsement questions beyond the federal standard. But the manual includes a section on agricultural hauling – read it. Grain trucks and livestock trailers are common here, and the test might ask about securing different types of cargo.
About the Kansas Combination Vehicles Test
Kansas is flat, but don't let that fool you. Hauling a loaded grain trailer down I-70 near Salina means fighting crosswinds that can push you into the next lane. The Combination Vehicles test makes sure you know how to keep that trailer behind you, not beside you.
You'll get 20 multiple-choice questions on coupling and uncoupling, trailer stability, and avoiding jackknives. The test follows federal standards, but Kansas examiners pay close attention to how you handle wind and winter slick spots – because you'll face both on I-35 and US-83.
If you're going for a Class A CDL in Kansas, this endorsement is mandatory. You take it after passing the General Knowledge test, and you need 16 out of 20 to pass. No exceptions.
Study the Kansas CDL manual, but think about real roads. That coupling sequence matters when you're hooking up a cattle trailer at a feedlot in Dodge City. Brake application matters when you're coming down a hill near the Flint Hills. The test checks your book knowledge, but it's built for Kansas driving.
