Kansas Doubles and Triples Test

About the Kansas Doubles and Triples Test

Kansas isn't called the Wheat State for nothing. You'll see doubles and triples hauling grain, fertilizer, and oil field equipment all over the state. From the flat plains of I-70 to the rolling hills of US-54, you need to know how to handle those extra trailers safely. That's where this practice test comes in.

Driving doubles in Kansas means dealing with wind gusts that can hit 40 mph without warning. You'll cross the Flint Hills where sudden downdrafts push against those tall trailers. Snow and ice on I-135 near McPherson make coupling even more critical. Our test covers these real conditions.

The Kansas DMV written exam for the Doubles/Triples endorsement has 20 questions. You need 16 correct to pass. We built this practice test to match the official format. Every question comes from the Kansas CDL manual. You won't see any surprise topics.

Use this test to find your weak spots. Then go back to the manual. Repeat until you're scoring 90% or higher. That way you'll walk into the Topeka or Wichita DMV confident — and you'll pass on your first try.

What This Test Covers

• Coupling and uncoupling trailers – critical for grain haulers on Kansas backroads where you hook up in tight farm yards.
• Air brake systems for doubles – Kansas winters mean moisture freeze-ups; know your air tank draining.
• Speed management on curves – those rolling Flint Hills roads demand slower speeds with a long combination vehicle.
• Off-tracking and path of travel – essential when merging onto I-70 from short on-ramps near truck stops.
• Weight distribution and chain placement – applies to every Kansas potato hauler running US-83.
• Emergency procedures for trailer separation – think quick reactions when a seal pops on US-281 near the Nebraska line.

Study Tips

Start with the Kansas CDL manual's Doubles and Triples section. Highlight the coupling steps – that's where most people lose points. Practice reciting each step out loud. You'll need to explain them during the pre-trip inspection at the DMV.

Book your Kansas CDL skills test online at the KS Department of Revenue website. Most offices require an appointment. Bring your CLP, valid ID, and medical certificate. The written test for endorsements costs $4 per endorsement – yes, just $4. Pay with cash or card.

Don't skip the air brake questions. Even though Kansas doesn't require an air brake endorsement for doubles if your vehicle has hydraulic brakes, most testers will ask about air systems. Know your governor cut-out and cut-in pressures. That's 120-130 psi and 100 psi respectively.

Kansas DMV Information

You can take the Kansas Doubles and Triples written test at any full-service CDL office. Big locations like Topeka (2700 SW 6th Ave), Wichita (1240 S. Broadway), and Salina (300 W. Ash) offer daily testing. Smaller offices like Hays or Garden City require a call first – they don't always have a CDL tester on staff.

No appointment is needed for the written endorsement test. Just bring your current Kansas CDL or CLP and a valid ID. Walk-ins are welcome, but get there before 3 PM to guarantee same-day testing. The test is on a computer. You'll get your results instantly.

Fee for the Doubles/Triples endorsement is $4. That's per endorsement, so if you're adding air brakes too, it's $8 total. Pay with check, cash, or debit card. You don't need a medical card if you already have a CDL. But if you're getting your first CLP, bring your DOT medical certificate.
