About the Arkansas Doubles and Triples Test

Arkansas’s highways carry a lot of freight—poultry, rice, timber, and more. Doubles and triples trailers are common on interstates like I-30, I-40, and I-55. You’ll see them hauling goods through the Ozarks and across the Mississippi Delta. That’s why the state requires a special endorsement. You need to know how to couple, inspect, and control these long rigs safely.

Arkansas weather adds another layer. Winter ice on I-40 near Alma can make a triple trailer’s rear swing unpredictable. Fog in the Arkansas River valley cuts visibility fast. You must adjust your driving. The state also has tight two-lane highways with sharp curves. A poorly balanced double can jackknife in an instant. Our practice test focuses on the maneuvers and checks that keep you out of trouble.

We built this test from the Arkansas CDL manual. It mirrors the real DMV exam. You’ll answer 20 questions. You need at least 16 correct to pass. The timer gives you 25 minutes—more than enough if you know the material. We don’t just quiz you. We explain each answer so you learn why it’s right.

Topics Covered

✓Inspecting coupling devices – Arkansas’s bumpy back roads can shake loose a poorly connected dolly.
✓Air brake systems for doubles/triples – you need reliable braking on long downhill grades near the Ozarks.
✓Safe following distances – extra length means more stopping room, especially on I-55’s flat, fast stretches.
✓Off-tracking and wide turns – many Arkansas intersections have tight radii; you need to swing wide without hitting curbs.
✓Loading and weight distribution – uneven loads cause sway on winding two-lane roads in the Ouachitas.
✓Accident procedures – what to do if a trailer jackknifes on a foggy morning along the Arkansas River.

Study Tips

Start with the Arkansas CDL manual’s doubles/triples chapter. Read it twice. Then take our practice test. Focus on the air brake questions—Arkansas’s hilly terrain demands flawless braking. The real test has 20 questions, and you can’t miss more than four. Don’t skip the coupling procedures; they’re a common weak spot.

Use the Arkansas DMV’s own practice materials if you can. Many testing locations offer a handbook at the counter. Write down the numbers for air brake pressure, slack adjuster travel, and trailer height. Memorize those. Then take our test again. You’ll be ready.

Arkansas Specific Information

You can take the Arkansas Doubles/Triples knowledge test at any State Police testing site. Most locations, including Little Rock and Springdale, require an appointment. Walk-ins aren’t guaranteed. The fee is $10 per endorsement, paid at the time of the test. Bring your valid CDL permit, Social Security card, and two proofs of Arkansas residency.

After you pass the written test, you’ll get a T endorsement on your license. You don’t need a separate road test for doubles/triples unless you’re adding it to a new CDL. The endorsement stays valid for your full CDL cycle. If you fail, you can retake the test the next business day. There’s no wait period.
