📘 Study Tips & State Info
Arkansas examiners don't play games. They want you to recite the coupling steps in order — from backing under the first trailer to hooking the last. Don't skip a step. Practice writing the sequence down until you can do it without thinking. Know the difference between a pintle hook and a fifth wheel for your doubles.
Focus on off-tracking. Arkansas has a lot of curved on-ramps and two-lane roads. The test will ask how much extra room you need when turning with two trailers. Remember: the rear trailer follows a tighter path. That's why you swing wide before turning. Study the diagrams in the Arkansas CDL manual — they show exact turning paths for different trailer lengths.
Finally, Arkansas weather matters. The test includes questions about reduced speed in rain, wind, and ice. Don't just memorize the numbers — understand why an empty double trailer is more likely to tip than a loaded one. If you can explain it, you'll pass.
The Arkansas State Police handles all CDL testing. You'll find exam sites in Little Rock, Springdale, Jonesboro, Fort Smith, Texarkana, and several other cities. Appointments are required — walk-ins rarely get in. You can book online through the Arkansas State Police website. Bring your valid Medical Examiner's Certificate, proof of Arkansas residency, and your Social Security card.
The Doubles and Triples endorsement costs $12.50 on top of your regular CDL fees. You must already hold a Class A CDL or be applying for one. The written test is 20 questions, 25 minutes. You can retake it the same day if you fail, but you'll have to pay the fee again. Arkansas does not offer the test in Spanish — you'll need an interpreter if you don't read English.
One unique thing: Arkansas requires you to pass the Combination Vehicles test before you can take the Doubles and Triples test. So study both. Also, if you plan to haul hazardous materials in your doubles, you'll need the Hazmat endorsement too — that means a TSA background check and an additional written test.
About the Arkansas Doubles and Triples Test
The Arkansas Doubles and Triples endorsement lets you operate combination vehicles pulling two or three trailers. Think poultry haulers on I-49 or freight doubles running I-30 through Little Rock. This test covers the specific skills you need: coupling and uncoupling multiple trailers, managing off-tracking on tight Ozark curves, and keeping everything stable when a gust hits you on the Mississippi River bridges.
Arkansas follows federal standards, so the test has 20 multiple-choice questions. You need 16 right (80%) to pass. The Arkansas State Police administers CDL testing at their exam sites — you'll take this endorsement test after passing General Knowledge and Combination Vehicles. Don't skip the air brakes part either; most doubles and triples in Arkansas use air brakes, and the test assumes you know them.
What makes Arkansas tricky? Our weather. Ice on I-40 near Ozark, sudden thunderstorms that flood low spots on I-55, and wind that can push an empty trailer sideways across the Delta flats. The test expects you to handle those conditions. Also, Arkansas has some of the tightest rural roads in the South — you'll need to understand how your rear trailer cuts corners when you're delivering to a feed mill off a two-lane highway.
Bottom line: this isn't just a memorization test. You need to understand how doubles and triples behave differently than a single trailer. Practice the coupling sequence until it's second nature. Know your off-tracking. And always, always check your air lines before you move.
